3. Lying down affects digestion

When you lie down, digestion naturally slows down. Gas that is easily expelled during the day can become trapped in the intestines at night, causing pressure, bloating, and increased flatulence. Some people also sleep in positions that facilitate the expulsion of gas, such as on their side or stomach.

If gas is causing you trouble sleeping, try slightly changing your head position or sleeping on your left side to aid digestion.

4. Food Intolerances.
Undiagnosed food intolerances, such as lactose or gluten sensitivity, can cause significant gas, especially after meals. When the body cannot properly digest certain ingredients, they ferment in the colon and produce excess gas.

If you think you have a food intolerance, consider talking to a doctor or trying an elimination diet under professional supervision.

5. Imbalance of the gut microbiota

The gut is teeming with bacteria that help break down food. When the balance of this bacterial flora is disrupted (due to antibiotics, a poor diet, or illness), excess gas can occur, especially at night. Conditions such as small intestinal bacterial overgrowth (SIBO) can cause gas, bloating, and discomfort, particularly when lying down.

Probiotics or fermented foods such as yogurt, kefir, and sauerkraut can help restore balance.
