About Gas

This site contains information from government publications about gas that have been reformatted and reorganized. There are numerous links to the original documents.

The goal is to make the information easier to find and to allow the sharing of information between users.

This is a very big undertaking and you can help me help others. Please add your comments or questions to any topic that concerns you. If you know of additional resources please include links to them.

I am especially looking for:

• Experiences of family members of people with gas
• Experiences of caregivers experienced with gas
• Experiences of physicians experienced with gas
• Experiences of researchers experienced with gas

• Information about specific gas products
• Information about specific gas diet plans
  
• Information about specific gas treatments
• Information about specific gas medications
• Information about hospitals specializing in the treatment of gas
• Information about clinics specializing in the treatment of gas
• Information about physicians specializing in the treatment of gas

If possible please include:

• Links to gas websites
• Links to gas blogs
• Links to gas news articles
• Links to gas research articles

Why do I have gas?

Everyone has gas. Burping or passing gas through the rectum is normal. Because it is embarrassing to burp or pass gas, many people believe they pass gas too often or have too much gas. It is rare for a person to have too much gas.

Most of the time gas is odorless. The odor comes from sulfur made by bacteria in the large intestine. Sometimes gas causes bloating and pain. Not everyone has these symptoms. How much gas the body makes and how sensitive a person is to gas in the large intestine have an effect on how uncomfortable having gas is.

What can I do about gas?

Changing what you eat and drink can help prevent or relieve gas. If you feel like you have too much gas, you might want to try these things before going to the doctor.

1. Cut down on foods that cause gas.

The amount of gas caused by certain foods varies from person to person. The only way to know your own limits is through trial and error. These are some foods that cause gas:

• beans
  
  
• vegetables such as broccoli, cabbage, brussels sprouts, onions, artichokes, and asparagus
  
  
• fruits such as pears, apples, and peaches
  
  
• whole grains such as whole wheat and bran
  
  
• soft drinks and fruit drinks
  
  
• milk and milk products, such as cheese and ice cream
  
  
• packaged foods that have lactose in them, such as bread, cereal, and salad dressing
  
  
• dietetic foods and sugarfree candies and gums
  
  

2. Drink plenty of water, non-"fizzy" liquids, and clear soup.

Try not to drink liquids that cause gas, like soda and beer. If you do drink these liquids, pour them into a glass first to let some of the "fizz" out.

3. Reduce the amount of air you swallow. Here are some ways to avoid swallowing air:

• Eat slower and chew more to cut down on the amount of air you swallow when you eat.
  
  
• Avoid chewing gum and eating hard candy.
  
  
• If you smoke, try to cut down or quit.
  
  
• If you have false teeth, see your dentist to make sure they fit right.
  
  

4. Keep a diary.

Write down the foods (and the amounts) that seem to cause you the most problems. Also keep track of the number of times you pass gas.

If you are still troubled by gas, you may want to see your doctor. Take your diary with you to help you answer the doctor's questions about eating habits and symptoms.
