Why do I feel bloated every night?

Feeling bloated at night is common, and it often comes from a mix of what and how you eat during the day plus how your digestive system handles it. Common reasons include:

• Gas buildup from swallowing air or from normal digestion throughout the day
• Larger or later dinners, which can leave your stomach feeling fuller at night
• Carbonated drinks, which add gas
• Eating too quickly, which can make you swallow more air
• Saltier meals, which can cause water retention and a puffy feeling
• Food sensitivities or trigger foods, such as lactose, onions, garlic, beans, certain vegetables, or sugar alcohols
• For some people, high-FODMAP foods can also trigger gas and bloating

A few things that may help:

• Eat a bit slower and chew well
• Try a smaller, lighter dinner
• Limit carbonated drinks in the evening
• Take a short walk after eating
• Notice whether specific foods consistently trigger symptoms

If the bloating happens most nights, it may be worth keeping a simple food and symptom log to spot patterns.

Seek medical care sooner if bloating comes with severe or worsening pain, vomiting, blood in the stool, unexplained weight loss, fever, persistent diarrhea, or if it’s new and persistent.
