Common Questions
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.
Why Am I Constipated?
Constipation means that a person has three bowel movements or fewer in a week. The stool is hard and dry. Sometimes it is painful to pass. You may feel "draggy" and full.
Why Do I Have Indigestion?
Indigestion, also known as upset stomach or dyspepsia, is a painful or burning feeling in the upper abdomen, often accompanied by nausea, abdominal bloating, belching, and sometimes vomiting.
How Does My Digestive System Work?
The digestive tract is a complex system of organs responsible for converting the food we eat into the nutrients we need to live. We would expect a system as well used as the digestive tract to be the source of many problems--and it is.
