Bloating is any abnormal general swelling, or increase in diameter of the abdominalarea. As a symptom, the patient feels a full and tight abdomen, which may cause abdominal pain. sometimes accompanied by borborygmus. Bloating may have several causes, the most common being accumulation of liquids and intestinal gas. Ascitesis the proper medical term for abdominal bloating caused by excessive accumulation of liquid inside the cavity.

Common causes for abdominal bloating are:

  • Overeating (gastric distension)
  • Lactose intolerance, fructose intoleranceand other food intolerances
  • Food allergy
  • Aerophagia(air swallowing, a nervous habit)
  • Alvarez' syndrome, hysterical or neurotic abdominal bloating without excess of gas in the digestive tract
  • Irritable bowel syndrome
  • Partial bowel obstruction
  • Gastric dumping syndromeor rapid gastric emptying
  • The ingestion of some gas-producing foods
  • Constipation
  • Splenic-flexure syndrome
  • Menstruation, dysmenorrheaand premenstrual stress syndrome
  • Polycystic ovary syndromeand ovarian cysts
  • Massive infestation with intestinal parasites, such as worms (e.g, Ascaris lumbricoides)
  • Diverticulosis

Important but uncommon causes of abdominal bloating include large intra-abdominal tumors, such as those arising from ovarian, liver, uterusand stomach cancer; and megacolon, an abnormal dilation of the colon, due to some diseases, such as Chagas disease, a parasiticinfection.

Gaseous bloating may be a consequence of cardiopulmonary resuscitationprocedures, due to the artificial mouth-to-mouth insuflation of air.

Postmortem bloating occurs in cadavers, due to the formation of gases by bacterial action and putrefactionof the internal tissues of the abdomen and the inside the intestines.

In some animals, like cats, dogsand cattle, gastric dilatation-volvulus, or bloatalso occurs when gas is trapped inside the stomach and a gastric torsion or volvulus prevents it from escaping.
