Farting is a normal physiological phenomenon,

Improper diet: Diet containing too much greasy, spicy and irritating food causes increased farting.

Indigestion: If the gastrointestinal tract is unable to digest and absorb the nutrients in food, it may cause increased farting.

Irritable Bowel Syndrome: Irritable Bowel Syndrome is a common functional disorder of the intestinal tract, which in turn causes increased farting.

Gastrointestinal inflammation: Gastrointestinal inflammation may cause intestinal mucosal congestion, edema, erosion and other injuries, which in turn cause increased farting.

Intestinal dysbiosis: Intestinal dysbiosis refers to abnormalities in the type and number of bacteria in the intestinal tract, which in turn causes increased farting.

Medication side effects: Some medications may have an irritating effect on the gastrointestinal tract, leading to abnormal peristalsis and increased gas production, which in turn causes increased farting.
