Internal hemorrhoids can cause many different types of problems, which are discussed below. It is important to remember, though, that there are a number of other conditions that can mimic the symptoms of hemorrhoids. Some examples of these other conditions include anal fissures, fistulas, abscesses, warts, and cancer. Do not ignore anal symptoms no matter how minor or benign they may seem.
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.
