Nighttime acid reflux is more than just an occasional inconvenience. For many people, symptoms such as chest burning, a sour taste, coughing, or disturbed sleep can quietly become part of their nightly routine. Gastroesophageal reflux disease (GERD) often worsens at night because lying down removes gravity’s natural help in keeping stomach acid where it belongs, allowing acid to creep upward and irritate the oesophagus during sleep.. In a recent Instagram post, Dr Kunal Sood, a Maryland-based physician specialising in anesthesiology and interventional pain medicine, shared a practical “cheat sheet” to manage nighttime acid reflux. One of the most common triggers, he pointed out, is eating too close to bedtime. “Short dinner-to-bed intervals are associated with higher GERD risk,” he noted. “Lying down soon after eating allows acid to travel upward and clear more slowly, worsening nighttime reflux and cough.” This habit, often overlooked, can set the stage for persistent nocturnal symptoms.. Dr Sood also highlighted simple positional and dietary strategies that can make a meaningful difference. Elevating the head of the bed, he explained, works because “gravity reduces overnight oesophageal acid exposure,” helping people wake up less often and reducing reflux-related coughing. Dietary choices matter too. Fried and spicy foods can aggravate reflux, while gentler options may help. As he observed, “Plant-forward diets are associated with lower GERD incidence.” Along with food and posture, Dr Sood discussed targeted therapies, such as alginates and medications like famotidine, noting that “bedtime H2 blockers can reduce nocturnal acid production and help targeted nighttime symptoms.”. But why does acid reflux tend to worsen specifically at night?. Dr Pranav Honnavara Srinivasan, consultant surgical gastroenterologist at Fortis Hospitals, tells indianexpress.com, “Acid reflux often worsens at night because several natural protective mechanisms are reduced during sleep. When we lie flat, gravity no longer helps keep stomach acid in the stomach, making it easier for acid to flow back into the oesophagus. Saliva production also drops at night, and saliva plays a key role in neutralising acid.”. ALSO READ | Dr Shriram Nene shares tips to avoid acid reflux, GERD. In addition, Dr Srinivasan says, swallowing frequency decreases during sleep, which means acid clearance from the oesophagus is slower. If dinner is late or heavy, the stomach remains full when a person lies down, increasing pressure on the lower oesophageal sphincter and worsening reflux symptoms.. View this post on Instagram. Identifying the dietary triggers that are most likely to worsen their nighttime GERD. Dr Srinivasan mentions that dietary triggers vary from person to person, so the most practical approach is “mindful observation.” Keeping a simple food and symptom diary for two to three weeks can help identify patterns.. “Common triggers include spicy foo
