Main causes of gas
Swallowing air while eating:
Excessive air enters the stomach by eating quickly, talking while eating, and drinking drinks through a straw.
Dietary habits:
Gas-producing foods: Legumes, cabbage, cauliflower, onions, and broccoli take time to digest, so they can cause gas.
Carbonated drinks: The gas contained in drinks like soda and cola can cause stomach discomfort.
Digestive problems:
Lactose intolerance: A condition in which the body is unable to digest milk or dairy products.
Constipation: Stool retention in the stomach can increase the activity of bacteria and produce more gas.
Bacterial activity: Some bacteria in the stomach produce gas when they digest food. This can be excessive in some people.
Other health problems: Irritable bowel syndrome (IBS), gastritis, and stomach infections can cause gas problems.
