Data and research on postpartum headaches are skewed towards severe headaches as many patients self-medicate with analgesics in the setting of mild or moderate headaches and never seek medical care. Because the features of many types of postpartum headaches overlap—and headache syndromes can exist concurrently—differentiation of the conditions that present with headaches in the postpartum period may be difficult. The threshold for advanced diagnostic testing and imaging is lower in this population than in those in a comparable age group, highlighting the importance of a detailed history-taking and physical examination with vigilance to the elicitation of red-flag historical features and symptoms and neurological findings, which are often subtle and easily overlooked.

Pathophysiology
The sharp increase in both primary and secondary pain in the head or upper neck. সহজ বাংলা: মাথাব্যথা।" data-rx-term="headache" data-rx-definition="Headache means pain in the head or upper neck. সহজ বাংলা: মাথাব্যথা।">headache presentations in the puerperium results from the many social and physiologic changes in this period. The postpartum period is rife with factors that may exacerbate primary headache disorders. These women also experience sleep deprivation, increased stress levels, disordered sleep cycles, and irregular nutritional intake, all of which can trigger primary headaches.[rx] The dramatic fluctuations in estrogen, serotonin, and oxytocin levels associated with childbirth and breastfeeding may also exacerbate underlying primary pain in the head or upper neck. সহজ বাংলা: মাথাব্যথা।" data-rx-term="headache" data-rx-definition="Headache means pain in the head or upper neck. সহজ বাংলা: মাথাব্যথা।">headache disorders.[rx] The physiologic changes of the puerperium also contribute to an increased risk of secondary pain in the head or upper neck. সহজ বাংলা: মাথাব্যথা।" data-rx-term="headache" data-rx-definition="Headache means pain in the head or upper neck. সহজ বাংলা: মাথাব্যথা।">headache syndromes. Ischemic stroke incidence rises due to hypercoagulability in pregnancy, reaching its peak in the immediate postpartum period.[rx][rx] Rising estrogen and progesterone levels lead to vasodilation and increased vascular distensibility, which contributes to the higher rate of rupture of vascular malformations and intracranial hemorrhages in the puerperium.[rx]

-
Vaginal vs. surgical delivery
-
Complications of the pregnancy, such as pre-eclampsia or gestational hypertension
-
Delivery complications, including bleeding and postpartum fevers
-
Use of epidural anesthesia
-
New medications
-
Illicit drug use
-
Personal or family history of hypercoagulability or bleeding syndromes
-
Shortness of breath
-
Chest pain
-

Evaluation
The diagnosis of primary headache disorders and PDPH is clinical; no additional laboratory or imaging studies are necessary. Laboratory workup for secondary headache syndromes in the puerperium includes a urinalysis, a spot urinary protein to creatinine ratio, complete blood count, comprehensive metabolic panel, and lactate dehydrogenase. Lumbar puncture with fluid analysis is necessary if meningitis is suspected. The imaging modality of choice differs based on the most likely suspected diagnosis. Non-contrasted head CT is rapid and non-invasive but is not sensitive to early ischemic strokes and sinus venous thrombosis.[rx][rx] It is most appropriate for the diagnosis of spontaneous and traumatic intracranial hemorrhage. For sinus venous thrombosis, CT venography is as sensitive as MR venography and is more readily available.[rx] MRI is most sensitive for early ischemic strokes.
Treatment of Postpartum Headache
Management of postpartum headaches varies by the cause of the headache. Management of primary headache exacerbations includes analgesia and counseling regarding the importance of consistent nutrition and sleep. The treatment of choice for PDPH is bed rest, analgesia, intravenous hydration, and caffeine supplementation. Patients who do not respond to this treatment within 48 hours may require a blood patch. The treatment of secondary causes of headache in the postpartum period often requires collaboration with consulting services both for acute management and risk factor modification. Headaches caused by preeclampsia resolve with treatment of the condition, including initiation of magnesium and anti-hypertensive medications and admission to an obstetrics service for monitoring. Ischemic stroke should undergo management with the aid of a neurologist for consideration of the initiation of thrombolytics or endovascular intervention. Spontaneous and traumatic intracranial hemorrhages may require neurosurgical intervention. Sinus venous thrombosis treatment is with systemic anticoagulation.[rx]
Complications
Prompt diagnosis and treatment initiation is imperative in secondary headache syndromes as delay can result in loss of life or permanent disability. The young age of this patient population makes the diagnosis of the life and limb-threatening disease particularly important, as it represents an opportunity for acute intervention that accounts for a significant increase in both years lived and disease-free time. It also adds significant social and medicolegal consequences for missed or delayed diagnosis.
