To avoid gas problems, make it a habit to chew your food slowly. Avoid drinking too much water with meals and drink water half an hour after meals to help ease digestion. If you experience chronic gas problems along with abdominal pain or blood in your stool, you should seek medical attention immediately.
The following factors may be behind the sudden gas problem:
Eating food quickly: When you swallow food quickly without chewing it properly, air enters the stomach along with the food. This causes bloating and gas.
Dietary changes: Suddenly eating more fiber-rich foods or eating too much nuts, beans, cabbage, and tubers can cause gas in the stomach.
Carbonated drinks: When you drink soda and cool drinks, the carbon dioxide in them accumulates in the stomach as gas.
Food intolerance: Some people may suddenly have gas when they eat milk or dairy products (Lactose intolerance). Some people also experience this problem when they eat wheat dishes.
Constipation: When stool accumulates in the intestines, gas is prevented from leaving and the stomach swells quickly.
