Abdominal Bloating Causes

Abdominal bloating is common. Many people experience the same type of bloating again and again. Normally, bloating that follows a predictable pattern is not a worry. When the pattern changes or bloating becomes worse than expected, it may be one of the following conditions:

Gas:  A buildup of gas in the stomach and intestines is among the most common causes of bloating. Other symptoms include:

  • Frequent burping
  • Passing too much gas
  • Feeling a sudden urge to pass stool
  • Feeling nauseous

Bloating caused by gas may cause mild discomfort up to intense pain. Some people describe feeling that there is something trapped inside their stomach.

Possible Causes of Gas Include:

  • Certain foods, including carbonated beverages, dairy, beans, cauliflower, broccoli, and cabbage
  • Swallowing air while eating or chewing gum
  • A stomach infection
  • Chronic illnesses, such as celiac disease or irritable bowel syndrome (IBS)
  • Indigestion

In most cases, gas goes away on its own after a few hours.

Indigestion: Indigestion, sometimes called dyspepsia, is discomfort or pain in the stomach that can include bloating. Most people experience brief episodes of indigestion from time to time.

It is often caused by:

  • Eating too much
  • Drinking excessive alcohol
  • Taking medications that irritate the stomach, such as ibuprofen
  • A minor stomach infection

Frequent indigestion with bloating that does not appear to be associated with food, or other apparent causes could be a sign of something more serious. Potential serious causes are a stomach ulcer or stomach cancer.

Infection: Stomach infections can cause bloating, which may be accompanied by:

  • Diarrhea
  • Vomiting
  • Nausea
  • Stomach pain

These can be caused by bacteria such as Escherichia coli or Helicobacter pylori — or a viral infection such as norovirus or rotavirus.

Stomach infections usually go away on their own after a few days. However, some people may become severely dehydrated or continue to get worse over several days.

  • Fever
  • Bloody stool
  • Severe and frequent vomiting

Gastroparesis: Gastroparesis is a disorder that affects regular stomach emptying. As a result, the nerves that regulate stomach motion stop working correctly, which causes food to pass much more slowly through the stomach and intestines. Symptoms include:

  • Bloating
  • Constipation
  • Feeling full quickly when eating
  • Loss of appetite
  • Heartburn
  • Nausea and vomiting
  • Pain and discomfort

Diseases such as diabetes or hypothyroidism sometimes cause gastroparesis.
