What Are Hemorrhoids?

How Do Hemorrhoids Develop?

The final sections of the digestive tract are called the rectum and the anal canal. This is where stool is stored just prior to elimination. Embedded within the wall of the canal are three inflatable areas called anal cushions. These cushions have a very important function. Whenever you put pressure on your abdomen, such as during lifting, straining, or coughing, the anal cushions instantly inflate with blood to form a strong seal that prevents you from leaking stool. With time, repeated inflations at high pressures can cause the anal cushions to stretch out. When this occurs, they are easily irritated and can cause lots of problems. The anal cushions have now become internal hemorrhoids.
