The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The NIDDK translates and disseminates research findings through its clearinghouses and education programs to increase knowledge and understanding about health and disease among patients, health professionals, and the public.
External hemorrhoids form under the skin around the anus. Bleeding during bowel movements is the most common sign of hemorrhoids. Your doctor can do a physical examination and perform other tests to confirm hemorrhoids and rule out more-serious conditions or diseases.
Also talk to your doctor if you know you have hemorrhoids and they cause pain, bleed frequently or excessively, or don't improve with home remedies. Don't assume rectal bleeding is due to hemorrhoids, especially if you are over 40 years old. Rectal bleeding can occur with other diseases, including colorectal cancer and anal cancer. If you have bleeding along with a marked change in bowel habits or if your stools change in color or consistency, consult your doctor.
These types of stools can signal more extensive bleeding elsewhere in your digestive tract.

Swollen veins hemorrhoids can develop from increased pressure in the lower rectum due to:. Hemorrhoids are more likely with aging because the tissues that support the veins in your rectum and anus can weaken and stretch. As you get older, you're at greater risk of hemorrhoids.
That's because the tissues that support the veins in your rectum and anus can weaken and stretch. This can also happen when you're pregnant, because the baby's weight puts pressure on the anal region. The best way to prevent hemorrhoids is to keep your stools soft, so they pass easily. To prevent hemorrhoids and reduce symptoms of hemorrhoids, follow these tips:.
Consider fiber supplements. Most people don't get enough of the recommended amount of fiber — 25 grams a day for women and 38 grams a day for men — in their diet. Studies have shown that over-the-counter fiber supplements, such as Metamucil and Citrucel, improve overall symptoms and bleeding from hemorrhoids. These products help keep stools soft and regular.
If you use fiber supplements, be sure to drink at least eight glasses of water or other fluids every day. Otherwise, the supplements can cause constipation or make constipation worse.
