Hemorrhoids (HEM-uh-roids), also called piles, are swollen veins in the anus and lower rectum. Hemorrhoids are similar to varicose veins. Hemorrhoids can develop inside the rectum, called internal hemorrhoids. They also can develop under the skin around the anus, called external hemorrhoids.
There are several options available to treat hemorrhoids. Many people get relief with home treatments and lifestyle changes.
Symptoms of hemorrhoids usually depend on the type of hemorrhoid.
Internal hemorrhoids lie inside the rectum. You usually can't see or feel them, and they rarely cause discomfort. But straining or irritation when passing stool can cause:
These are under the skin around the anus. Symptoms might include:
Blood can pool in an external hemorrhoid and form a clot, called a thrombus. A thrombosed hemorrhoid can result in:
If you have bleeding during bowel movements or you have hemorrhoids that don't improve after a week of home care, talk to your health care provider.
Don't assume rectal bleeding is due to hemorrhoids, especially if you have changes in bowel habits or if your stools change in color or consistency. Rectal bleeding can happen with other diseases, including colorectal cancer and anal cancer.
Seek emergency care if you have large amounts of rectal bleeding, lightheadedness, dizziness or faintness.
The veins around the anus tend to stretch under pressure and may bulge or swell. Hemorrhoids can develop from increased pressure in the lower rectum due to:
As people age, the risk of hemorrhoids increases. That's because the tissues that support the veins in the rectum and anus can weaken and stretch. This also can happen during pregnancy because the baby's weight puts pressure on the anal region.
Complications of hemorrhoids are rare but may include:
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 fiber in their diets. Studies have shown that nonprescription fiber supplements, such as psyllium (Metamucil, Konsyl, others) or methylcellulose (Citrucel), can lessen symptoms and bleeding from hemorrhoids.
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 it worse.
Your health care provider might be able to see external hemorrhoids. Diagnosing internal hemorrhoids might include an exam of your anal canal and rectum.
Your health care provider might want to look at your entire colon using colonoscopy if:
You can often relieve the mild pain, swelling and inflammation of hemorrhoids with home treatments.
With these treatments, hemorrhoid symptoms often go away within a week. See your health care provider within a week if you don't get relief. Contact your provider sooner if you have severe pain or bleeding.
Your hemorrhoids might only produce mild discomfort. In this case, your health care provider may suggest creams, ointments, suppositories or pads that you can buy without a prescription. These products contain ingredients such as witch hazel, or hydrocortisone and lidocaine, which can temporarily relieve pain and itching.
Hydrocortisone is a steroid that can thin your skin when used for more than a week. Ask your health care provider how long you should use it.
If a painful blood clot has formed within an external hemorrhoid, your health care provider can remove the hemorrhoid. Removal can provide relief right away. This procedure, done with a medicine that numbs a part of the body, also called a local anesthetic, works best when done within 72 hours of getting a clot.
For bleeding that doesn't stop or for painful hemorrhoids, your health care provider might recommend one of the other minimally invasive procedures available. These treatments can be done in your provider's office or another outpatient setting. They don't usually require numbing medicine.
Rubber band ligation. Your health care provider places one or two tiny rubber bands around the base of an internal hemorrhoid to cut off its blood flow. The hemorrhoid withers and falls off within a week.
Hemorrhoid banding can be uncomfortable and cause bleeding. The bleeding might begin 2 to 4 days after the procedure but is rarely severe. Sometimes, more-serious complications can occur.
Only a small percentage of people with hemorrhoids need surgery to remove them. However, if other procedures haven't worked or you have large hemorrhoids, your health care provider might recommend one of the following:
Hemorrhoid removal, also called a hemorrhoidectomy. Your surgeon removes extra tissue that causes bleeding by using one of various techniques. The surgery can be done with a local anesthetic combined with a medicine to help you feel calm or less anxious, also called a sedative. Spinal anesthesia or general anesthesia also may be used.
Hemorrhoidectomy is the most effective and complete way to treat severe or recurring hemorrhoids. Complications can include temporarily having a hard time urinating, which can lead to urinary tract infections. This complication happens mainly after spinal anesthesia.
Most people have some pain after the procedure, which medicines can relieve. Soaking in a warm bath also might help.
Hemorrhoid stapling. This procedure, called stapled hemorrhoidopexy, blocks blood flow to hemorrhoidal tissue. It is typically used only for internal hemorrhoids.
Stapling generally involves less pain than hemorrhoidectomy and lets you get back to regular activities sooner. Compared with hemorrhoidectomy, however, stapling has been associated with a greater risk of hemorrhoids coming back and rectal prolapse. Rectal prolapse is when part of the rectum pushes through the anus.
Complications also can include bleeding, troubles emptying the bladder and pain. A rare complication is a life-threatening blood infection called sepsis.
Talk with your health care provider about the best option for you.
If you have symptoms of hemorrhoids, make an appointment with your primary care provider. If needed, your provider might refer you to one or more specialists for evaluation and treatment. These may include a doctor with expertise in the digestive system, called a gastroenterologist, or a colon and rectal surgeon.
Here are some suggestions to help you get ready for your appointment.
Be aware of any pre-appointment restrictions. When you make the appointment, ask if there's anything you need to do in advance.
Make a list of:
For hemorrhoids, some questions to ask your provider include:
Don't hesitate to ask other questions.
Your health care provider is likely to ask you questions, including:
Before your appointment, take steps to soften your stools. Eat more high-fiber foods, such as fruits, vegetables and whole grains. Consider a nonprescription fiber supplement, such as Metamucil or Citrucel. Drinking 6 to 8 glasses of water a day also might help relieve your symptoms.
