Laryngopharyngeal reflux (LPR), also known as silent reflux, is a condition where stomach acid travels up the esophagus and into the throat and larynx. Unlike typical acid reflux, LPR often doesn’t cause heartburn or indigestion, making it difficult to diagnose.

Types:

There are no distinct types of LPR; however, it can vary in severity from mild to severe.

Causes 

1. Dietary Factors: Consuming acidic or spicy foods, caffeine, alcohol, and fatty foods can trigger LPR.
2. Obesity: Being overweight puts pressure on the stomach, which can force acid up into the throat.
3. Smoking: Tobacco smoke irritates the throat and weakens the muscles that prevent acid reflux.
4. Hiatal Hernia: When the upper part of the stomach protrudes through the diaphragm, it can lead to reflux.
5. Pregnancy: Hormonal changes and pressure from the growing uterus can cause acid reflux.
6. Medications: Certain medications, such as aspirin, ibuprofen, and muscle relaxants, can relax the muscles that keep acid in the stomach.
7. Stress: Stress can increase stomach acid production and worsen reflux symptoms.
8. Lack of Sleep: Poor sleep habits can weaken the body’s defenses against acid reflux.
9. Tight Clothing: Wearing tight belts or waistbands can put pressure on the stomach and trigger reflux.
10. Eating Before Bed: Eating large meals or snacks close to bedtime can increase the risk of reflux during sleep.
11. Lying Down After Eating: Gravity helps keep stomach acid down, so lying down after a meal can promote reflux.
12. Carbonated Beverages: Drinking fizzy drinks can cause bloating and increase pressure on the stomach.
13. Certain Foods: Some people may be sensitive to particular foods like tomatoes, citrus fruits, onions, and chocolate, which can trigger reflux.
14. Eating Too Quickly: Eating too fast can lead to swallowing air, which can exacerbate reflux symptoms.
15. Excessive Alcohol Consumption: Alcohol can relax the muscles that control the opening between the esophagus and stomach.
16. Carbonated Beverages: The bubbles in carbonated drinks can expand in the stomach, leading to increased pressure and reflux.
17. Certain Medications: Some medications, such as calcium channel blockers and nitrates, can relax the muscles of the esophagus, promoting reflux.
18. Delayed Stomach Emptying: Conditions like gastroparesis, where the stomach takes too long to empty its contents, can increase the risk of reflux.
19. Smoking: Tobacco smoke can weaken the muscles that keep stomach acid from flowing back into the esophagus.
20. Genetic Factors: Some people may have a genetic predisposition to LPR.

12. Difficulty Breathing: Feeling like it’s hard to catch a breath or breathlessness.
13. Wheezing: Wheezing or whistling sounds when breathing.
14. Nausea: Feeling nauseous or experiencing an upset stomach.
15. Difficulty Sleeping: LPR symptoms can worsen at night, leading to disrupted sleep.
16. Chronic Fatigue: Poor sleep quality due to LPR can result in ongoing fatigue.
17. Voice Changes: Changes in voice pitch or quality.
18. Dry Cough: A persistent cough that doesn’t produce mucus.
19. Difficulty Speaking: Struggling to speak clearly or feeling like the voice is strained.
