Gas (flatus), burping, and bloating are all normal conditions. Gas is made in the stomach and intestines as your body breaks down food into energy. Gas and burping may sometimes be embarrassing. Bloating, which is a feeling of fullness in the abdomen, can make you uncomfortable. Although many people think that they pass gas too often or have too much gas, it is rare to have too much gas. Changing what you eat and drink can sometimes cut down on gas and relieve discomfort caused by gas.

Belching or burping (eructation) is the voluntary or involuntary, sometimes noisy release of air from the stomach or esophagus through the mouth. Burping 3 to 4 times after eating a meal is normal and is usually caused by swallowing air. Other causes of burping include nervous habits or other medical conditions, such as an ulcer or a gallbladder problem. In some cultures, a person may belch loudly after eating to show appreciation for the meal.

All people pass gas, but some people produce more gas than others. It is normal to pass gas from 6 to 20 times a day. Although this may embarrass or annoy you, excess intestinal gas usually is not caused by a serious health condition.

Common causes of gas and bloating include:

• Swallowed air. If swallowed air is not burped up, it passes through the digestive tract and is released through the anus as flatus. Excessive air swallowing may cause hiccups.
• Foods and beverages. The amount of gas that different foods cause varies from person to person.
• Constipation. This can cause bloating but generally does not increase gas. For more information, see the topics Constipation, Age 11 and Younger or Constipation, Age 12 and Older.
• Medicines or nutritional supplements. Both prescription and nonprescription medicines, as well as dietary supplements, can cause bloating and gas as side effects.
• A medical condition, such as a bowel obstruction or Crohn's disease.
• Changes in hormone levels. It is common for women to have bloating right before their periods because their bodies retain fluid.

Dyspepsia is a medical term that is used to describe a vague feeling of fullness, gnawing, or burning in the chest or upper abdomen, especially after eating. A person may describe this feeling as "gas." Other symptoms may occur at the same time, such as belching, rumbling noises in the abdomen, increased flatus, poor appetite, and a change in bowel habits. Causes of dyspepsia can vary from minor to serious.

Occasionally, a person may dismiss serious symptoms, such as symptoms of a heart attack, as "just gas or indigestion."

Home Treatment

Gas, bloating, and burping

Gas, bloating, and burping are usually harmless and go away without any treatment. If gas, bloating, or burping is making you uncomfortable, take the following steps to help manage your symptoms:

• Increase the amount of fluid you drink, especially water. Avoid carbonated drinks and alcoholic beverages.
• Avoid foods that cause gas, such as beans, broccoli, cabbage, and bran. The amount of gas that different foods cause varies from person to person.
• Avoid swallowing air. Swallowing air may increase your symptoms.
  • Eat slowly. Avoid gulping food or beverages. When you rush through meals or eat on the run, you are more likely to swallow air.
  • Chew your food thoroughly before you swallow.
  • Avoid drinking through a straw.
  • Avoid chewing gum or eating hard candy.
  • Do not smoke or use other tobacco products.
  • If you wear dentures, check with a dentist to make sure they fit properly.
  • Keep calm. Tension and anxiety can cause you to swallow air.
• Take a medicine that you can buy without a prescription. Be sure to follow the instructions on the label.
  • Activated charcoal tablets, such as CharcoCaps, may decrease odor from gas. Charcoal is usually taken after meals or at the first sign of gas discomfort.
  • Antacids, such as Di-Gel, Maalox Anti-Gas, and Mylanta Gas, allow gas to be belched away more easily. However, these medicines often have no effect on gas that is already in the intestines.
  • Food enzymes, such as Beano, which help break down the sugars found in vegetables and grains, can be added to foods that cause you to have gas.

Hiccups

Hiccups are usually harmless and go away without any treatment. But if hiccups are making you uncomfortable, the following safe and easy home remedies may help you manage your symptoms.

• Swallow a teaspoon of dry granulated sugar. Do not use this remedy if you have been diagnosed with diabetes.
• Hold your breath and counting slowly to 10.
• Breathe repeatedly into a paper bag for a limited period of time.
• Quickly drink a glass of cold water.

Symptoms to Watch For During Home Treatment

Use the Check Your Symptoms section to evaluate the symptoms if any of the following occur during home treatment:

• New symptoms develop, such as abdominal pain, constipation, diarrhea, heartburn, or vomiting.
• Hiccups last longer than 24 hours.
• Hiccups return frequently.
• Symptoms become more severe or frequent.

Prevention

Gas, bloating, and burping

You may be able to prevent gas, burping, and bloating.

• Take steps to avoid swallowing air:
  • Eat slowly. Avoid gulping food or beverages. When you rush through meals or eat on the run, you are more likely to swallow air.
  • Chew your food thoroughly before you swallow.
  • Avoid drinking through a straw.
  • Avoid chewing gum or eating hard candy.
  • Do not smoke or use other tobacco products.
  • If you wear dentures, check with a dentist to make sure they fit properly.
  • Keep calm. Tension and anxiety can cause you to swallow air.
• Keep a food diary if you suspect that gas is caused by certain foods. Write down what you eat or drink and when symptoms occur to help you identify foods or drinks that may cause gas. Once these problem foods are identified, avoid or limit them to reduce or prevent symptoms.
  • Talk with your health professional or a dietitian about ways to maintain a balanced diet if you want to permanently eliminate certain foods or drinks. For more information, see the topic Healthy Eating.
  • If you suspect milk or other dairy products are causing your symptoms, try limiting or eliminating these foods. For more information, see the topic Lactose Intolerance.
  • If you cook with dry beans, soak them in water overnight, then pour off the water and cook the soaked beans in fresh water. This may reduce the amount of natural sugars in the beans after the cooling process and help prevent gas and bloating.
• Do not overeat. Large meals can make you feel bloated. Try eating 6 small meals a day rather than 3 large ones.
• Avoid constipation, which is a common cause of bloating. For more information, see the topic Constipation, Age 12 and Older or Constipation, Age 11 and Younger.
• Avoid laxatives.
• Use an antigas product that you can buy without a prescription.
  • Food enzymes, such as Beano, which help break down the sugars found in vegetables and grains, can be added to foods that cause you to have gas.
  • If you have lactose intolerance, lactase enzyme supplements, such as Dairy Ease and LactAid, can be taken with dairy products to help break down lactose in food.
  • Peppermint and other herbs (carminatives) that soothe the digestive tract may permit belching and decrease bloating after large meals.
• Exercise regularly.

Hiccups

You may be able to prevent the hiccups by avoiding things that trigger them.

• Take steps to avoid swallowing air:
  • Eat slowly. Avoid gulping food or beverages. When you rush through meals or eat on the run, you are more likely to swallow air.
  • Chew your food thoroughly before you swallow.
  • Avoid drinking through a straw.
  • Avoid chewing gum or eating hard candy.
  • Do not smoke or use other tobacco products.
  • If you wear dentures, check with a dentist to make sure they fit properly.
