Causes of a bloated stomach include overeating, eating fatty foods, eating too quickly and presence of gas in the stomach, states WebMD. Other causes include irritable bowel syndrome, stress, smoking, and conditions such as lactose intolerance and celiac disease, according to Mayo Clinic.
A bloated stomach is usually related to what and how a person eats, notes WebMD. Fats take a longer time to digest and absorb than carbohydrates or protein, causing the stomach to stay full for longer. Gas can also build in the stomach due to the inability of the gastrointestinal tract to move swallowed air and air produced by the bacteria in the gut through it. A person can swallow air through chewing gum, drinking through a straw, sucking on hard candy and guzzling carbonated beverages. Changes in bowel function and the inability of the intestines to digest and absorb some food components can also cause a bloated stomach, explains Mayo Clinic.
Abdominal bloating can be a symptom of health conditions such as ovarian cancer, wheat gluten intolerance, fluid in the abdominal cavity and impaired digestion due to insufficient production of digestive enzymes by the pancreas, states Healthline. Treatment includes avoiding drinking through a straw, eating slowly, avoiding chewing gum, limiting intake of carbonated drinks and avoiding gassy foods such as lentils and dried beans.
