This uncomfortable feeling of fullness or tightness can make your stomach appear larger and clothes to feel tighter. Bloating may be caused by how and what you eat, abnormal reactions to food, or certain medical conditions. How you relieve bloating depends on what's causing it. This article looks at the causes and symptoms of bloating plus how to treat and prevent it, and when it's concerning enough to call your healthcare provider.

Can Bloating Cause Shortness of Breath? What Causes Bloating? Bloating tends to be linked to certain foods and beverages, as well as eating habits that cause the build-up of gasses in the digestive system. But there are other potential causes as well. How You Eat If you have regular bloating, the first thing to do is take a look at your eating habits. Eating too much: Bloating happens when you put more into your stomach than it can easily handle.Eating too fast: Eating quickly can cause you to swallow a lot of air, which can lead to bloating. Abdominal bloating will continue until the food in an overfull stomach is digested or accumulated gas is released. This can take hours or days. What You Eat or Drink What you eat or drink can also lead to bloating. Gum and carbonated beverages: These can increase the amount of air you swallow. High-fiber foods: These can increase healthy gut bacteria, which can cause bloating if you aren't used to eating them. Alcohol: Wine, beer, and hard alcohol may cause temporary bloating by irritating your stomach lining. Food Sensitivity, Intolerance, and Allergy Food sensitives occur when your body isn't able to process certain substance. When you eat foods containing that substance, it triggers an immune reaction that produces symptoms but is not life-threatening (as an allergy can be). Common substances that can trigger food sensitivities and intolerances are: Gluten, a protein found in wheat and other grains, for reasons that are yet unknown Lactose, a sugar in dairy products, in people who lack the enzyme needed to digest it Food allergies can range from mild to life-threatening. A substance in food you're allergic to triggers an immune-system response that leads to symptoms, including bloating. Common food allergies include: EggsMilk and other dairy productsPeanutsTree nuts Identifying Food Allergy Symptoms Health Conditions Several medical conditions can cause bloating and other digestive symptoms. Common ones are: Constipation: Stool backed up in the bowels; may occur alone or as a symptom of another condition Celiac disease: An autoimmune disorder; gluten passing through the small intestine triggers an immune-system attack Irritable bowel syndrome (IBS): A gastrointestinal disorder often triggered by particular foods or beverages, which vary from person to person Bloating can also be caused by the hormonal fluctuations that occur during menstruation. Splenic Flexure Syndrome: What You Need to Know When to See a Healthcare Provider Bloating is rarely a sign of a serious medical problem. If you notice that you become bloated after eating certain foods, bring it up to your healthcare provider. You may have a food sensitivity or intolerance. Call for an appointment if you have long-term bloating that doesn't respond to changes in eating habits or OTC treatments. It may be due to certain conditions that need to be diagnosed and treated. Besides those conditions already mentioned, this includes kidney or heart failure—both of which can cause fluid to accumulate in the abdomen. Identifying Trigger Foods It helps to keep a food journal in which you note what you eat and when bloating occurs. You and your healthcare provider may then be able to see a pattern. Be sure to note any other symptoms, as well. Bloating Treatment Most bloating doesn't need medical care.

Summary Bloating—when your abdomen sticks out more than usual—is usually accompanied by a feeling of fullness and discomfort. However, it is rarely something to worry about. Bloating can be caused by eating habits like eating too quickly or too much, certain foods and beverages, constipation, or hormonal changes related to the menstrual period. But bloating can also have a medical cause that requires diagnosis and treatment, including IBS, food sensitivities, food intolerances, food allergies, and even heart or liver failure. Many OTC medications may help relieve bloating. If you continue to have frequent bloating, make an appointment with your healthcare provider. Frequently Asked Questions How can I avoid bloating? To prevent bloating, try to avoid foods that make you gassy, as well as bubbly drinks. Eating slowly may also help. How long should I take to eat? It takes about 20 minutes for your stomach to signal your brain that you're full. Taking between 20 minutes and 30 minutes to eat a meal may lead to eating less and a reduced chance of bloating. Why should I avoid drinking with a straw? Drinking with a straw increases the likelihood of swallowing air, which can lead to gas and bloating. The same goes for fizzy drinks, like soda, which contain lots of bubbles. 11 Sources Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.
