What is bloating?
A bloated stomach leaves you with a feeling of fullness, tightness and swelling in your abdomen (belly). You can have bloating after eating a heavy, rich meal or as a symptom of several different medical conditions.
Most people experience bloating at some time or another. Stomach bloating usually occurs when gas or air builds up in the intestines, leading to notable swelling in the belly area. Most of the time, bloating isn’t a cause for concern, but persistent, frequent or severe stomach bloating can be a sign of a more serious medical issue.

Symptoms of a bloated stomach
The most common symptom of bloating is a feeling of fullness in the abdomen, almost like you have an inflated balloon in your stomach. Other symptoms may include:
- Abdominal rumbling or gurgling
- Belching
- Distended abdomen (swelling in the stomach area)
- Gassiness
- Stomach pain
When to see a doctor
While it’s normal to experience stomach pain and bloating occasionally, see your doctor if your stomach feels bloated and you have any of the following symptoms:
- Blood in your stool
- Heartburn that isn’t alleviated with over-the-counter meds
- Nausea or vomiting
- Vaginal bleeding between periods or after menopause
- Weight loss with no known cause
It’s also a good idea to see your doctor if you’re experiencing extreme stomach bloating, a persistent stomachache or a hard, bloated stomach that has lasted for longer than a few days.
What causes bloating in the stomach?
The causes of stomach bloating can vary depending on the part of your stomach that’s affected. Upper stomach bloating is most often associated with swallowing too much air when eating or drinking, while lower stomach bloating can be related to gas produced during the digestive process.
Other causes for stomach bloating include:
- Acid reflux
- Blockages in the bowel or bladder
- Cancer of the stomach, ovaries, uterus, colon and pancreas
- Certain medications
- Crohn’s disease
- Diverticulitis
- Food intolerances and sensitivities
- Hormonal fluctuations
- Infection
- Irritable bowel syndrome
- Lactose intolerance
- Liver disease
- Menstruation
- Overeating
- Small intestine bacterial overgrowth
Stomach bloating and pain are also common after certain surgical procedures, such as a hernia repair, during which surgeons pump gas into the abdomen. This type of bloating typically goes away on its own in the days after surgery.
Foods and drinks that lead to stomach bloating
A bloated stomach is most often caused by excessive air or gas. Because of that, your eating habits can impact whether and when you experience bloating. Eating or drinking quickly can cause you to swallow more air while you’re gulping down food, which can lead to bloating. In addition, certain foods and drinks can increase the risk of bloating. They include:
- Beans: Contain sugars and fiber that can’t be broken down by the digestive system, leading to excess gas
- Carbonated beverages: Can introduce excess air into the digestive system or lead to excess gas
- Cruciferous vegetables such as broccoli, cauliflower or cabbage: Contain fiber and carbohydrates that are poorly absorbed by the digestive system and produce excess gas
- Dairy products: Contain lactose, which can cause excess gas in people with lactose intolerance
- Fruit such as apples, peaches, bananas and prunes: Contain sugars and fiber that aren’t easily digested, leading to excess gas
- Hard candy or chewing gum: Can introduce excess air into the digestive system
- Sugar-free candy or gum: Contain sugar alcohols, which can’t be fully digested, leading to excess gas
- Whole grains: Contain fiber and carbohydrates that can’t be broken down by the digestive system, leading to excess gas
How is bloating diagnosed?
Bloating is typically a symptom of another issue, and not usually a health concern on its own. If you are concerned about stomach bloating, your doctor will likely try to diagnose the underlying cause.
A comprehensive physical exam allows your doctor to understand your diet and lifestyle as well as your history of health conditions and treatments for those health issues. From there, they’ll decide whether you need more tests and, if so, what kind.
How can I reduce stomach bloating
In many cases, stomach bloating can be relieved by tweaking your eating habits and using home remedies to alleviate discomfort and swelling.
Dietary changes can help you prevent bloating from happening in the first place. If you experience frequent bloating, it may be helpful to keep a food diary of when you experience bloating and what you ate around that time. This can help you learn what foods may trigger bloating and other digestive symptoms, such as discomfort and stomach cramps.
