Congenital diarrhea caused by mutation in GUCY2C is a very rare inherited bowel disease in which a change in the GUCY2C gene makes the intestine send out too much salt and water into the bowel. This causes watery diarrhea from birth or early infancy. In many children, the diarrhea is secretory, which means it continues even when feeding is reduced, because the problem is in the body’s salt-and-water transport system, not only in food digestion. This condition is often placed in the group called congenital sodium diarrhea, and some families are described as having familial GUCY2C diarrhea syndrome. [1]
The GUCY2C gene makes a receptor called guanylate cyclase C (GC-C) on the lining of the intestine. When this receptor becomes too active because of a harmful mutation, it raises cGMP inside the intestinal cells. That high cGMP level turns on CFTR chloride secretion and turns down NHE3 sodium absorption. As a result, chloride, sodium, and water move into the bowel lumen, and the child passes large volumes of loose stool. This is why dehydration, weight loss, and acid-base or electrolyte problems can happen early in life. [2]
Congenital diarrhea caused by a GUCY2C mutation is a very rare inherited bowel disease. Most reported disease-causing GUCY2C changes are activating mutations. They make the intestinal guanylate cyclase-C (GC-C) receptor too active. This raises intestinal cGMP, reduces sodium absorption, increases chloride and water secretion, and causes very early-onset secretory diarrhea, salt loss, dehydration, poor weight gain, and sometimes bowel dilation or obstruction. In many babies, symptoms begin before birth or in the newborn period. Treatment is mainly supportive, because there is no established FDA-approved cure that corrects the gene defect itself. 1 2 3 4
Congenital diarrhea caused by GUCY2C mutation is also described under names such as familial GUCY2C diarrhea syndrome, GUCY2C-associated congenital sodium diarrhea, or congenital secretory diarrhea due to activating GUCY2C mutation. The main medical goal is to protect the child from dehydration, electrolyte loss, growth failure, nutrition deficiency, and complications from long-term intestinal failure care. 1 2 3
This disease is important because it can start before birth. Some babies have polyhydramnios during pregnancy, which means too much amniotic fluid, and some have dilated fluid-filled bowel loops on prenatal imaging. After birth, the stool may be so watery that it is mistaken for urine. Some affected people improve somewhat with age, but many still need careful follow-up because the disease can be linked with dehydration, kidney injury, bowel obstruction, inflammation, or later gut problems such as inflammatory bowel disease in some reported patients. [3]
Another names
This condition may be described by several names in medical writing. Common names include GUCY2C-related congenital diarrhea, GUCY2C-related congenital sodium diarrhea, familial diarrhea syndrome caused by activating GUCY2C mutation, familial GUCY2C diarrhea syndrome, and in some databases diarrhea type 6 or a non-syndromic congenital sodium diarrhea spectrum. The exact wording may differ between papers, but they all describe a similar disease process caused by overactive GC-C signaling in the intestine. [4]
Types
Type 1: Familial autosomal dominant form. In this type, the mutation is passed through a family from one affected parent to a child. The classic example is the Norwegian family reported with early-onset chronic diarrhea caused by an activating GUCY2C mutation. [5]
Type 2: De novo sporadic form. In this type, the mutation is new in the child and is not found in either parent. Several patients with congenital sodium diarrhea were reported with new, spontaneous GUCY2C mutations. [6]
Type 3: Prenatal or intrauterine-onset form. In this type, the disease already affects the baby during pregnancy and may cause polyhydramnios and swollen bowel loops before birth. [7]
Type 4: Severe neonatal secretory form. This type presents in the first days or weeks of life with large-volume watery diarrhea, dehydration, abdominal distension, and need for urgent fluid and electrolyte replacement. [8]
Type 5: Milder chronic childhood or adult-persistent form. Some patients continue to have lifelong diarrhea but with lower severity later in life, because symptoms may lessen as the child gets older. [9]
Causes
For this disease, the main true cause is an activating mutation in the GUCY2C gene. So, unlike common diarrhea, there are not 20 totally separate main causes. To match your requested format honestly, here are 20 cause-related genetic and disease mechanisms that explain how this condition develops. [10]
1. Activating mutation in GUCY2C. This is the core cause. The mutation makes the GC-C receptor too active. [11]
2. Autosomal dominant inheritance. One altered copy can be enough to cause disease in some families. [12]
3. De novo mutation. A new mutation can arise in the child without family history. [13]
4. Mutation in the catalytic domain. Some mutations in this important working part of the receptor strongly increase activity. [14]
5. Mutation in the kinase homology domain. This can disturb receptor control and raise signaling. [15]
6. Mutation in the linker region. Changes here can also make the receptor over-responsive. [16]
7. Excess basal GC-C activity. Some mutations make the receptor active even without strong stimulation. [17]
8. Excess ligand-stimulated GC-C activity. The receptor responds too strongly to normal gut ligands such as guanylin and uroguanylin. [18]
9. Increased intracellular cGMP. Overactive receptor signaling raises cGMP inside enterocytes. [19]
10. PKGII activation. High cGMP activates downstream protein kinase pathways that promote secretion. [20]
11. Indirect PKA activation through PDE3 effects. This helps amplify the secretory signal. [21]
12. Increased CFTR chloride secretion. More chloride enters the bowel, pulling water with it. [22]
13. Reduced NHE3 sodium absorption. Less sodium is taken back into the body, so stool sodium stays high. [23]
14. Net intestinal water loss. Salt movement into the bowel causes water loss and watery diarrhea. [24]
15. Secretory diarrhea physiology. The bowel keeps secreting fluid even during fasting, unlike purely diet-triggered diarrhea. [25]
16. Fetal intestinal secretion before birth. In severe cases, the same process starts in utero and contributes to polyhydramnios. [26]
17. High fecal sodium loss. The disease causes sodium-rich stool, which is a defining mechanism in congenital sodium diarrhea. [27]
18. Associated chloride loss. GUCY2C-driven disease may also show chloride loss because of downstream CFTR effects. [28]
19. Disturbed intestinal motility and dilation. Excess fluid inside bowel loops may lead to distension and obstruction-like problems. [29]
20. Inflammatory tendency in some patients. Some reported patients later developed inflammatory bowel disease or arthritis, suggesting that abnormal GC-C signaling may also affect gut inflammation in a subset of cases. [30]
Symptoms
1. Watery diarrhea from birth or early infancy. This is the main symptom. The stool is usually large in volume and very loose. [31]
2. Diarrhea that may continue during fasting. Because the problem is secretory, the stool may not stop fully when feeding is reduced. [32]
3. Dehydration. Large fluid losses can quickly dry the body, especially in newborns. [33]
4. Weight loss or poor weight gain. The child may fail to grow well because of fluid loss and feeding difficulty. [34]
5. Abdominal distension. The belly can look swollen because the bowel is full of fluid. [35]
6. Stool mistaken for urine. The stool can be so watery that caregivers may think it is only urine. [36]
7. Hyponatremia or low body sodium. Sodium loss in stool may lead to weakness, poor feeding, or illness. [37]
8. Metabolic acidosis. The child may become acidotic because of heavy electrolyte loss. [38]
9. Polyhydramnios in pregnancy. This is a symptom-sign of fetal disease before birth rather than after birth. [39]
10. Premature birth. Some affected babies are born early after complicated pregnancies with excess amniotic fluid. [40]
11. Vomiting or feeding intolerance. Some case reports describe vomiting with the diarrheal illness. [41]
12. Acute kidney injury or kidney stress. Delay in diagnosis can lead to renal problems from severe dehydration. [42]
13. Bowel obstruction or ileus-like episodes. Some patients have obstruction, volvulus, or severe dysmotility. [43]
14. Later inflammatory bowel disease symptoms. A minority of patients may later develop chronic gut inflammation, blood or mucus, abdominal pain, or related bowel symptoms. [44]
15. Long-term chronic diarrhea in older children or adults. Even when severity improves with age, loose stools may continue for many years. [45]
Diagnostic tests
A doctor does not diagnose this disease with only one test. The diagnosis usually comes from a pattern: early watery diarrhea, high stool sodium, secretory stool studies, signs before birth or soon after birth, and finally genetic confirmation of a GUCY2C mutation. [46]
Physical exam tests
1. Hydration assessment. The doctor checks dry mouth, sunken eyes, poor tears, weak pulses, slow capillary refill, and general appearance. This helps show how much fluid has been lost. [47]
2. Body weight and growth measurement. Repeated weight checks are very important because progressive weight loss may be an early clue. [48]
3. Abdominal examination. The doctor looks for distension, visible bowel fullness, tenderness, or signs of obstruction. [49]
4. Stool volume and stool appearance assessment. Very watery, high-volume stool that may look like urine supports a secretory congenital diarrhea disorder. [50]
Manual test / bedside evaluation
5. Fasting response observation. Secretory diarrhea often continues despite fasting, which helps separate it from diet-induced diarrhea. [51]
6. Strict stool-versus-urine separation and collection. This bedside step is very important, because watery stool can be confused with urine and can mislead diagnosis. [52]
7. Input-output charting. Measuring all fluid taken in and all stool and urine passed helps show the severity of losses. [53]
8. Prenatal history review. Careful history of polyhydramnios, preterm delivery, or fetal bowel dilation can strongly support congenital sodium diarrhea. [54]
Lab and pathological tests
9. Serum electrolytes. Blood sodium, potassium, chloride, and bicarbonate are checked to identify electrolyte loss and metabolic acidosis. [55]
10. Blood gas analysis. This shows whether the child has metabolic acidosis and how severe it is. [56]
11. Kidney function tests. Urea and creatinine are checked because dehydration may injure the kidneys. [57]
12. Stool electrolyte analysis. Measuring stool sodium, chloride, and potassium is central. High stool sodium strongly supports congenital sodium diarrhea. [58]
13. Stool osmotic gap calculation. Secretory diarrhea usually has a low stool osmotic gap, helping separate it from carbohydrate malabsorption. [59]
14. Urine sodium. This can be low when the body is sodium-depleted and trying to conserve salt. [60]
15. Fractional sodium excretion. This is a more accurate marker of sodium status than urine sodium alone in some patients. [61]
16. Inflammatory markers such as CRP and ESR. These are not specific for GUCY2C disease, but they may help if doctors suspect very-early-onset inflammatory bowel disease or inflammatory complications. [62]
17. Genetic testing for GUCY2C. This is the key confirmatory test. It may be done by targeted gene testing, congenital diarrhea panel, exome sequencing, or genome sequencing. [63]
18. Intestinal biopsy when diagnosis is unclear. Biopsy is not always needed for GUCY2C disease itself, but in the work-up of congenital diarrheas it may help rule out other enteropathies such as tufting enteropathy or microvillus inclusion disease. [64]
Electrodiagnostic / functional tests
19. Functional epithelial testing in research settings. Some centers study patient cells, organoids, or receptor signaling to show increased GC-C activity and excess cGMP signaling, but this is mainly a specialist or research tool. [65]
Imaging tests
20. Prenatal or postnatal imaging. Prenatal ultrasound can show polyhydramnios and dilated bowel loops. Fetal MRI can help when congenital diarrheal disease is suspected before birth. After birth, abdominal imaging may help assess distension or obstruction-like complications. [66]
Non-Pharmacological Treatments
- Oral rehydration therapy is one of the most important treatments. It gives back water and salts that are lost in stool. Its purpose is to prevent dehydration. Its mechanism is simple: glucose and sodium move together across the gut wall, and water follows. In mild disease or between severe episodes, it can reduce hospital visits and support safer feeding. 1 2
- Intravenous fluid replacement is used when stool losses are heavy or the child cannot drink enough. Its purpose is urgent correction of dehydration, shock, and poor blood circulation. Its mechanism is direct replacement of lost body fluid into the bloodstream. In severe congenital secretory diarrhea, IV fluids are often lifesaving. 1 2
- Careful sodium replacement is essential because this disorder causes large fecal sodium loss. Its purpose is to correct hyponatremia, weakness, poor feeding, and poor growth. Its mechanism is restoration of extracellular sodium balance so nerves, muscles, and circulation can work normally. 1 2
- Potassium replacement is often needed when chronic diarrhea causes low potassium. Its purpose is to prevent muscle weakness, fatigue, heart rhythm problems, and worsening dehydration effects. Its mechanism is restoration of the body’s main intracellular cation. 1 2
- Correction of metabolic acidosis with oral or IV alkali support is often necessary. Its purpose is to normalize blood acid-base balance, improve appetite, and protect growth. Its mechanism is buffering excess acid when bicarbonate is lost or metabolism becomes unstable during severe diarrhea. 1 2
- Early nutrition assessment by a pediatric dietitian is very important. Its purpose is to prevent calorie, protein, and micronutrient deficiency. Its mechanism is matching intake to stool loss, absorption ability, and growth needs. 1 2
- Enteral nutrition when tolerated helps keep the gut active. Its purpose is to support growth and reduce total parenteral nutrition dependence when possible. Its mechanism is stimulation of the bowel lining and preservation of gut function. 1 2
- Amino acid-based or elemental formula may help some infants who do not tolerate standard feeds. Its purpose is to improve feeding tolerance and nutrition delivery. Its mechanism is reduced digestive work and easier absorption of nutrients. 1 2
- Small, frequent feeds can be useful. Their purpose is to improve tolerance and reduce sudden fluid shifts into the bowel. Their mechanism is lower meal load at one time, which may reduce feeding stress. 1 2
- Parenteral nutrition (PN/TPN) is often needed in severe disease. Its purpose is to provide full nutrition when the intestine cannot keep up with fluid and nutrient loss. Its mechanism is direct intravenous delivery of calories, protein, fat, vitamins, minerals, and trace elements. 1 2
- Intestinal rehabilitation program follow-up is helpful for complex cases. Its purpose is to reduce complications, optimize feeding, and move toward the safest long-term plan. Its mechanism is coordinated care by gastroenterology, surgery, nutrition, pharmacy, and nursing teams. 1 2
- Central line care education is essential in children on PN. Its purpose is to prevent bloodstream infection and line failure. Its mechanism is sterile handling, dressing care, and early recognition of infection signs. 1 2
- Regular weight, length, and head growth monitoring is a treatment step, not just a check. Its purpose is to show whether hydration and nutrition are enough. Its mechanism is early detection of growth faltering so feeding and fluid plans can be changed fast. 1 2
- Daily stool and fluid balance records are very useful. Their purpose is to measure disease burden and guide fluid replacement. Their mechanism is simple tracking of intake, urine, stool volume, vomiting, and weight change. 1 2
- Routine electrolyte monitoring helps prevent sudden instability. Its purpose is to detect sodium, potassium, chloride, magnesium, and bicarbonate problems early. Its mechanism is lab-based adjustment of fluids and supplements before major symptoms appear. 1 2
- Micronutrient monitoring is needed in chronic diarrhea and PN dependence. Its purpose is to prevent trace element and vitamin deficiency. Its mechanism is scheduled blood testing and nutrition adjustment. 1 2
- Prompt treatment of dehydration episodes at home or hospital is important. Its purpose is to stop kidney injury, lethargy, and shock. Its mechanism is early action when diarrhea rises, urine falls, or the child becomes sleepy. 1 2
- Genetic counseling helps families understand recurrence risk and testing options. Its purpose is informed planning for future pregnancy and family screening. Its mechanism is explanation of inheritance, mutation testing, and prenatal options. 1 2
- Psychosocial and caregiver support matters in chronic rare disease. Its purpose is to improve treatment adherence and reduce caregiver burnout. Its mechanism is education, planning, and emotional support for long-term home care. 1 2
- Rapid referral to specialist pediatric gastroenterology is a major treatment step. Its purpose is to confirm diagnosis, prevent delay, and manage severe fluid loss safely. Its mechanism is specialized testing and coordinated intestinal failure care. 1 2
Drug Treatments
There is no FDA-approved medicine that directly cures the GUCY2C mutation. The drugs below are supportive or complication-directed medicines that may be used in selected patients under specialist supervision. They are not all proven specifically for every child with GUCY2C diarrhea. 1 2 3
- Loperamide is an antidiarrheal that slows gut movement. FDA labeling supports symptom control of diarrhea in selected settings, but use in infants and very young children needs great caution. Purpose: reduce stool frequency. Mechanism: opioid receptor action in the gut slows transit and improves water absorption. Side effects can include constipation, abdominal swelling, drowsiness, and dangerous heart rhythm problems if overdosed. 1 2
- Octreotide is a somatostatin analog sometimes used off-label for high-output secretory states. Purpose: decrease intestinal secretion. Mechanism: suppresses several GI hormones and may reduce stool output in selected patients. Side effects include gallstones, blood sugar changes, abdominal pain, and bradycardia. 1 2
- Potassium chloride is used when diarrhea causes hypokalemia. Purpose: restore potassium and protect muscle and heart function. Mechanism: direct electrolyte replacement. Side effects include nausea, vomiting, and GI irritation; severe cases may need IV therapy instead of oral therapy. 1
- Sodium chloride injection is used for fluid and electrolyte replenishment. Purpose: treat dehydration and sodium depletion. Mechanism: isotonic IV replacement expands circulating volume and replaces sodium and chloride. Side effects include fluid overload in vulnerable patients. 1
- Sodium bicarbonate may be used when metabolic acidosis develops. Purpose: correct dangerous acid-base imbalance. Mechanism: bicarbonate buffers excess acid. Side effects include alkalosis, sodium overload, and fluid issues if not monitored carefully. 1
- Magnesium sulfate may be needed if magnesium loss occurs with severe diarrhea or long-term nutrition support. Purpose: treat hypomagnesemia. Mechanism: direct magnesium replacement. Side effects include low blood pressure, flushing, and toxicity if given too fast or in kidney failure. 1
- Zinc sulfate injection can be added to parenteral nutrition when zinc deficiency risk is high. Purpose: replace zinc needed for growth, immunity, and tissue repair. Mechanism: trace element replenishment. FDA labeling notes that higher monitored daily doses may be needed in patients with excess stool or ileostomy output. 1
- Parenteral multivitamin infusion is used in children dependent on IV nutrition. Purpose: prevent multiple vitamin deficiencies. Mechanism: direct intravenous vitamin replacement when enteral intake is not enough. Side effects depend on product and dose. 1 2
- Teduglutide is a GLP-2 analog approved for short bowel syndrome with parenteral support dependence, not for GUCY2C mutation itself. Purpose: help selected patients with intestinal failure reduce parenteral support. Mechanism: improves mucosal growth and absorption. Side effects include abdominal pain, fluid overload, and GI obstruction risks. 1
- Oral rehydration salts formulations are cornerstone supportive therapy, though formulations vary and are not a gene-specific FDA cure. Purpose: replace sodium, glucose, and water losses. Mechanism: sodium-glucose cotransport enhances water absorption. 1 2
- Antibiotics for line infection or bacterial complications are used only when infection is present. Purpose: treat sepsis or catheter-related infection. Mechanism: kill or suppress pathogenic bacteria. Choice depends on culture results, not on the gene mutation itself. 1 2
- Antifungals for catheter-related fungal infection are sometimes needed in PN-dependent patients. Purpose: treat invasive fungal infection. Mechanism: inhibit fungal growth or destroy fungal cell membranes. 1 2
- Ursodiol may be considered if parenteral nutrition-associated cholestatic liver disease develops. Purpose: support bile flow and protect the liver in selected patients. Mechanism: hydrophilic bile acid effect. This treats a complication, not the diarrhea gene defect. 1 2
- Acid suppression medicines may be used when reflux, gastritis, or tube feeding intolerance coexists. Purpose: improve comfort and protect the upper gut when clinically indicated. Mechanism: lower gastric acid exposure. They do not fix secretory diarrhea itself. 1 2
- Pain or cramp relief medicines may be used carefully in bowel obstruction episodes or postoperative care. Purpose: symptom relief. Mechanism depends on the medicine used. These are supportive only and require medical supervision. 1 2
- Electrolyte additives in PN such as sodium, potassium, and magnesium are often part of daily treatment. Purpose: replace ongoing stool losses. Mechanism: direct IV replacement tailored by lab results. 1 2
- Trace element preparations in PN are used when long-term IV nutrition is needed. Purpose: prevent deficiency of zinc and other elements important for enzymes, growth, and healing. Mechanism: controlled IV supplementation. 1 2
- Lipid emulsions for PN are used to provide energy and essential fatty acids in intestinal failure. Purpose: maintain growth and avoid energy deficiency. Mechanism: IV fat delivery bypasses the gut. Product choice depends on age, liver status, and team protocol. 1 2
- Glucose-containing IV solutions are used during acute illness or fasting. Purpose: support hydration and prevent catabolism. Mechanism: provide immediate fluid and carbohydrate support while stool losses are corrected. 1 2
- Investigational GC-C inhibitors are being studied because they target the disease mechanism more directly. Purpose: reduce excessive GC-C signaling. Mechanism: block overactive receptor activity and lower secretory drive. At present, these are research-stage, not standard FDA-approved treatment for routine care. 1 2
Dietary Molecular Supplements
- Zinc may support mucosal repair and reduce diarrhea burden in some children with diarrhea, although evidence is broader for pediatric diarrhea in general than for this rare mutation specifically. 1 2
- Oral sodium supplements may be needed because sodium loss is a central problem in GUCY2C-related disease. They help maintain hydration, growth, and nerve-muscle function. 1 2
- Potassium supplements may support muscle function and heart rhythm when chronic stool losses lower potassium. 1 2
- Bicarbonate or citrate salts may be used to support acid-base balance in selected patients with metabolic acidosis. 1 2
- Magnesium may be needed in patients with chronic intestinal loss or long-term PN. 1 2
- Calcium and vitamin D support may be needed when nutrition is poor or PN is long term. They help bone health and growth. 1 2
- Iron may be required if chronic illness or poor intake leads to iron deficiency. 1 2
- Folate may support red blood cell production in children with poor nutrition intake. 1 2
- Vitamin B12 may be needed in patients with long-term intestinal failure or poor intake patterns. 1 2
- Complete multivitamin and trace element support may be necessary when enteral intake is not enough to cover daily needs. 1 2
Drugs for immunity booster, regenerative, or stem cell support
At present, no FDA-approved immunity-booster drug, regenerative drug, or stem cell drug is established as a proven treatment for congenital diarrhea caused by GUCY2C mutation. This is important to say clearly. The options below are related intestinal rehabilitation tools or investigational approaches, not true gene-correcting cures. 1 2
- Teduglutide may help selected patients with intestinal failure by improving absorptive capacity, but it is not an immune booster and not a direct GUCY2C cure. 1
- Somatropin has been used in some intestinal failure and short bowel settings to support adaptation, but not as a standard treatment for GUCY2C diarrhea itself. 1
- PN-associated micronutrient optimization can improve immune function indirectly by correcting deficiency, but this is nutritional support, not a stem cell therapy. 1
- Fish-oil or mixed lipid PN strategies may reduce liver complications in intestinal failure, but they do not repair the mutated receptor. 1
- Investigational GC-C inhibitors are the most mechanism-based research direction, but they remain experimental. 1
- Future gene or cell therapies are a research hope, but there is no routine approved stem cell drug for this condition at this time. 1 2
Surgeries
- Central venous catheter placement is often needed for long-term parenteral nutrition. It is done because the child needs reliable IV access for fluids, nutrition, and electrolytes. 1 2
- Ileostomy or other decompressive stoma surgery may be needed in rare patients with bowel obstruction, massive bowel dilation, or difficult management of intestinal contents. 1 2
- Surgery for bowel obstruction or adhesions may be needed if recurrent obstruction develops. It is done to relieve blockage and protect bowel health. 1 2
- Line revision or replacement surgery may be required when a central line is infected, blocked, or damaged. It is done to keep life-supporting nutrition access safe. 1 2
- Intestinal transplantation is a last-resort option in severe irreversible intestinal failure with major PN complications. It is not common, but it may be considered in highly selected cases. 1 2
Preventions
- Prevent dehydration by starting oral or IV replacement early during worsening diarrhea. 1
- Prevent sodium deficiency by regular monitoring and replacement. 1
- Prevent potassium deficiency by scheduled lab follow-up. 1
- Prevent malnutrition through early dietitian-guided feeding plans. 1
- Prevent growth failure by frequent weight and length checks. 1
- Prevent central line infection with sterile catheter care. 1
- Prevent micronutrient deficiency with regular nutrition labs. 1
- Prevent diagnostic delay with early genetic testing in persistent neonatal secretory diarrhea. 1
- Prevent family confusion with genetic counseling and clear home-care teaching. 1
- Prevent severe complications by long-term specialist follow-up in an intestinal rehabilitation center. 1
When to see doctors
Seek urgent medical care if the child has very low urine output, sunken eyes, unusual sleepiness, poor feeding, repeated vomiting, fast breathing, severe weakness, fever, blood in stool, abdominal swelling, or sudden worsening of diarrhea. These signs can mean dehydration, electrolyte crisis, infection, or bowel obstruction. Regular follow-up with pediatric gastroenterology is also needed even when the child looks stable. 1 2 3
What to eat and what to avoid
Use feeds that the child’s specialist team recommends, often including carefully planned formula, enough sodium, enough calories, and nutrition adjusted to stool losses. Some patients do better with elemental or amino acid-based formula, small frequent feeds, and close fluid tracking. Avoid random diet changes, sugary drinks without salt balance, dehydration, and any supplement started without the gastroenterology team. Avoid assuming that common diarrhea diets will work for this rare genetic secretory disease. 1 2 3
