What is bloated stomach?

Bloated stomach is any abnormal gas swelling or increase in diameter of the abdominal area. Unlike the common myth, the cause of bloating is strictly not fluid retention. In bloating, the patient feels tightness around abdomen which can cause uneasiness and pain (1).

The pathophysiology of bloating is complicated and incompletely understood, some individuals can get a bloated stomach without any specific cause. Let us have a look at otherwise common causes that lead to bloating and abdominal distension.

What causes bloating?

Eating too much or too fast

Overeating is one of the main reasons for bloating. It leads to stomach expansion to accommodate the increased volume of food (2).

When you eat too fast, you tend to swallow air with every morsel which also triggers bloating. Also talking while eating leads to air gulping with morsels, which is a common cause of a distended stomach.

Food Intolerances

For certain people digesting ordinary food can lead to the production of excessive gas, nausea, and cause bloating. Lactose intolerance is a fairly common condition wherein it becomes difficult for the person to digest dairy products (3).

Fructose intolerance is also seen in individuals who are unable to process sugar in fruits. Artificial sugar substitutes like sorbitol also cause bloating in some individuals.

Gas-producing foods

Certain cruciferous vegetables like broccoli, cabbage, brussels sprouts, asparagus, cauliflower, and beans contain a complex sugar called raffinose.

The metabolism of raffinose causes excess gas during digestion resulting in a  bloated stomach (4). If you are already symptomatic with bloating try and avoid these food items.

Imbalance in fiber intake

Fibrous food like artichoke, pea, bananas, avocado is essential for proper functioning of our digestive system. Lack of fiber in the diet can cause constipation.

As a result of this, the intestine gets stuffed and the gas is entrapped in between causing distension of abdomen. It is common for individuals with constipation to have a  bloated belly.

Chronic stress or anxiety

Our digestive system functions primarily due to digestive enzymes. Chronic stress can cause an increase in cortisol levels in our blood.

Our digestive enzymes are sensitive to this hormone, and thus people with anxiety usually experience stomach upset, bloating, constipation, diarrhea, and nausea.

Inflammatory bowel disorders

Inflammatory bowel disorders such as irritable bowel syndrome, Coeliac disease, and Crohn’s disease cause inflammation and irritation of bowel lining(5).

This inflammation is a result of our own immunity acting against the intestine. The gas which is produced is unable to be pass through the inflammative bowel, leading to bloating.


Spicy meals including garlic and onion, fatty food, raw fruits like tomato, tangerines, and caffeine require more acid production for digestion.

Heartburn occurs when this excess acid moves from the stomach up to the esophagus. This gastric reflux causes bloating, nausea, belching, and flatulence.


Bloating and abdominal pain occurs accompanying pre-menstruation syndrome that many women experience. Hormonal fluctuations in estrogen levels and progesterone level trigger bloating.

Women experiencing dysmenorrhea also have shown symptoms of abdominal pain, hormonal imbalance and bloating.

A decrease in LB count

Lactobacillus is an essential bacteria found in our gut lining. It aids in proper digestion of food. An imbalance in the intestinal flora causes gas production leading to bloating(6).

Lactobacillus keeps the other opportunistic bacteria in check, an increase in other bacterial counts can cause serious bloating.


Certain medications such as aspirin, NSAIDs, opioids, antacids, stool bulking medication causes gas build up leading to distention and bloating.

Overuse of antibiotics causes a decrease in the functional bacteria levels in our gut which are necessary for proper digestion. This irrevocably leads to bloating.

Few other abdominal bloating causes include

  • Alvarez’ syndrome, bloating of unknown or psychogenic origin
  • Gastric dumping syndrome
  • Splenic-flexure syndrome
  • Infestation with intestinal parasites like Ascaris
  • Chagas disease, a parasitic infection
  • Polycystic ovary syndrome and ovarian cysts
  • Ovarian cancer
  • Diverticulosis
  • Celiac disease
  • Salivary hypersecretion and dehydration.
  • Megacolon, abnormal dilation of the colon.
  • Aerophagia, air swallowing habit
  • Partial bowel obstruction
  • Visceral fat

Conventional treatment

Many over the counter medication such as Pepto-Bismol and Simethicone help alleviate bloating symptoms. Activated charcoal tablets have also proven effective in treating stomach upset and preventing bloated stomach.

For those with lactose intolerance, consuming Lactaid which is lactase enzyme will help prevent gas production and bloating.
