At night, digestion naturally slows down. Eating onions close to bedtime may lead to:
Acid reflux or heartburn, particularly in people with GERD
Gas and bloating, which can cause pressure and discomfort when lying down
Stomach irritation, making it harder to relax and fall asleep
Gastroenterologists note that reflux symptoms are more likely when you lie flat, which is why onions eaten at dinner or as late-night snacks can disturb sleep quality.
