What causes abdominal bloating?
Causes of abdominal bloating can include gas, fluid retention, IBS, food intolerances, menstrual symptoms, and infections. People can often treat bloating at home, but some causes may need medical attention.
Abdominal bloating — and uncomfortable, full feeling in the belly area — can be alarming, particularly when painful. The abdomen can look larger than usual or be shaped abnormally. Persons may also have piercing abdominal pain. Yet, most times, the cause may just be indigestion or gas building up in the stomach and gut.
Usually, bloating is not a concern if it:
- is associated with food or eating
- does not get worse with time
- goes away within a day or two
In this article, we look at the causes of abdominal bloating, treatments, and how to know when to see a doctor.
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 include a stomach ulcer or stomach cancer.
Infection
Stomach infections can cause bloating, which may be accompanied by:
- diarrhea
- vomiting
- nausea
- stomach pain
These can occur due to bacteria such as Escherichia coli or Helicobacter pylori — or a viral infection such as norovirus or rotavirus.
Some stomach infections may go away on their own after a few days. However, some infections do not resolve without treatment. As such, if symptoms persist for over a week, it is advisable to contact a doctor.
Individuals should also contact a doctor if the bloating coincides with:
- fever
- bloody stool
- severe and frequent vomiting
Small intestinal bacterial overgrowth (SIBO)
The stomach and intestines are home to various bacteria, which help the body digest food. Disturbing the balance of bacteria can lead to an increase in harmful bacteria in the small intestine. This is known as small intestinal bacterial overgrowth or SIBO.
SIBO can cause bloating, frequent diarrhea, and difficulties digesting food and absorbing nutrients. These chronic symptoms may lead to osteoporosis, metabolic bone disease, or weight loss in some people.
Fluid retention
Salty foods, changes in hormone levels, and food intolerances can cause a person’s body to hold more fluid than it would otherwise. For instance, some females may become bloated right before their periods or early in pregnancy.
Chronic bloating caused by fluid retention could have a more serious cause, such as liver or kidney failure or diabetes. If the bloating does not go away, a person should speak with a doctor.
Food intolerances
Some people become bloated after eating certain foods — for example, people who have lactose intolerance, gluten intolerance, or celiac disease. Bloating can be linked to diarrhea or stomach pain and will go away by removing the problem-causing food.

Chronic disorders
Irritable bowel disease (IBD) and IBS often produce bloating. For example, Crohn’s disease is a type of IBD and digestive tract inflammation and has a specific course and treatment. In contrast, the cause of IBS is unknown and is often diagnosed when there is no specific reason for symptoms.
Both IBS and IBD can cause gas, diarrhea, and vomiting. If a person is also experiencing unexplained weight loss, they’re more likely to have Crohn’s disease.
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, as well as certain gastrointestinal surgeries, can sometimes cause gastroparesis.
Gynecological disorders
Some gynecological problems cause bloating, such as a monthly period or menopause. Also, endometriosis — in which the womb lining attaches to the stomach or intestines — can cause bloating, cramping, and stomach pain.

bloating as the only symptom of a problem. However weight gain, constipation, and pain could also occur.
Constipation
Bloating begins when food contents build up in the gut. This condition — called constipation — can come from:
- dehydration
- not enough fiber in the diet
- food intolerance
- pregnancy
- certain bowel disorders
- nutrient deficiencies, including magnesium
- certain medicines
In most people, laxatives, exercise, drinking water, or changing the diet can resolve episodes of constipation and bloating.
Other causes
Less commonly, abdominal bloating may be due to other serious conditions. People with gallstones or gallbladder disease may experience intense abdominal pain that mimics bloating.
Ascites, a pool of fluid in the abdominal cavity is another condition that leads to abdominal pain and bloating. The most common cause of this fluid buildup is liver disease.
Outlook
Abdominal bloating can be upsetting and painful. There are many simple causes of abdominal bloating, such as gas, constipation, indigestion, food intolerance, and fluid retention.
These symptoms are easily treated with home remedies, lifestyle changes, OTC medications, and prescription medications.
For most people, the cause can be treated at home and is something simple. A person should speak with a doctor if the symptoms worsen or do not go away after a few days.
