Hemorrhoids

Symptoms

Symptoms of hemorrhoids usually depend on the type of hemorrhoid.

Internal hemorrhoids

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:

• Painless bleeding. You might notice small amounts of bright red blood on your toilet tissue or in the toilet.
• A hemorrhoid to push through the anal opening, called a prolapsed or protruding hemorrhoid. This may result in pain and irritation.

External hemorrhoids

These are under the skin around the anus. Symptoms might include:

• Itching or irritation in the anal area.
• Pain or discomfort.
• Swelling around the anus.
• Bleeding.

Thrombosed hemorrhoids

Blood can pool in an external hemorrhoid and form a clot, called a thrombus. A thrombosed hemorrhoid can result in:

• Severe pain.
• Swelling.
• Inflammation.
• A hard, discolored lump near the anus.

When to see a doctor

If you have bleeding during bowel movements or you have hemorrhoids that don't improve after a week of home care, talk with a healthcare professional.

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.

Risk factors

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 area.

Prevention

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:

• Eat high-fiber foods. Eat more fruits, vegetables and whole grains. Doing so softens the stool and increases its bulk. This will help you avoid the straining that can cause hemorrhoids. Add fiber to your diet slowly to avoid problems with gas.
• Drink plenty of fluids. Drink 6 to 8 glasses of water and other liquids each day to help keep stools soft. Avoiding alcohol also may help.

• 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.

• Don't strain. Straining and holding your breath when trying to pass stool create greater pressure in the veins in the lower rectum.
• Exercise. Stay active to help prevent constipation and reduce pressure on veins. Exercise also can help you lose excess weight that might be causing your hemorrhoids or making them worse.
• Avoid long periods of sitting. Sitting too long, especially on the toilet, can increase the pressure on the veins in the anus.

Treatment

Home remedies

You can often lessen the mild pain, swelling and inflammation of hemorrhoids with home treatments.

• Eat high-fiber foods. Eat more foods that are high in fiber. This helps soften the stool and increases its bulk, which can help you avoid straining. Add fiber to your diet slowly to avoid problems with gas.
• Use topical treatments. Apply a hemorrhoid cream or suppository containing hydrocortisone that you can buy without a prescription. You also can use pads containing witch hazel or a numbing medicine.
• Soak regularly in a warm bath or sitz bath. Soak your anal area in plain warm water for 10 to 15 minutes two or three times a day. A sitz bath fits over the toilet.
• Take pain relievers by mouth. You can temporarily use acetaminophen (Tylenol, others), aspirin or ibuprofen (Advil, Motrin IB, others) to help ease your discomfort.

With these treatments, hemorrhoid symptoms often go away within a week. See a healthcare professional if you don't get relief after a week of home care. Contact a health professional sooner if you have severe pain or bleeding.

Medicines

Your hemorrhoids might only produce mild discomfort. In this case, a healthcare professional 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 professional how long you should use it.

External hemorrhoid thrombectomy

If a painful blood clot has formed within an external hemorrhoid, a healthcare professional can remove the hemorrhoid. Removal can provide relief right away. This procedure is done with a medicine that numbs a part of the body, called a local anesthetic. Thrombectomy works best when done within 72 hours of getting a clot.

Minimally invasive procedures

For bleeding that doesn't stop or for painful hemorrhoids, a healthcare professional might recommend a minimally invasive procedure. These treatments can be done in a medical office or another outpatient setting. They don't usually require numbing medicine.

• Rubber band ligation. A healthcare professional 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.

• Sclerotherapy. With sclerotherapy, a health professional injects a chemical solution into the hemorrhoid tissue to shrink it. While the injection causes little or no pain, it might be less effective than rubber band ligation.
• Coagulation. Coagulation techniques use laser or infrared light or heat. They cause small, bleeding internal hemorrhoids to harden and shrivel. Coagulation has few side effects and usually causes little discomfort.

Surgical procedures

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, a healthcare professional might recommend one of the following:

• Hemorrhoid removal, also called 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 having a hard time urinating, which can lead to urinary tract infections. This complication is short-term and happens mainly after spinal anesthesia.

  Most people have some pain after the procedure. Medicines can ease this pain. 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 linked to a greater risk of hemorrhoids coming back and rectal prolapse. Rectal prolapse happens when part of the rectum pushes through the anus.

  Complications also can include pain, bleeding and trouble emptying the bladder. A rare complication is a life-threatening blood infection called sepsis.

  Talk with a healthcare professional about the best option for you.
