Hemorrhoids are swollen blood vessels in and around the anus and lower rectum. They stretch under pressure and are similar to varicose veins in the legs. Hemorrhoids are either internal or external.
- Internal hemorrhoids develop inside the anus. They are painless and sometimes bleed a lot during bowel movements. They may also protrude during bowel movements. If they protrude from the anal opening and cannot be pushed back, they can cause severe pain.
- External hemorrhoids develop under the skin around the anus and can easily be felt or seen as a lump. They bleed when broken by straining, rubbing, or scratching.

Hemorrhoids are more common in older adults. Factors that increase your risk of getting hemorrhoids include:
- Straining when trying to pass a stool
- Chronic constipation or diarrhea
- Sitting on the toilet for long periods of time
- Pressure on the veins from pregnancy and childbirth
- Family members with hemorrhoids
- Chronic cough
- Liver disease
- Chronic use of enemas or laxatives
In most cases, symptoms will go away within several days. Although many people have hemorrhoids, not all experience symptoms.
Common symptoms include:
Bleeding from the anus that may appear:
- On the stool
- On the toilet paper
- In the toilet bowl
- Anal itching and burning
- Swelling and pain during bowel movements
- Sensitive lumps of various sizes around the anus
Bleeding from the rectum or blood in the stool can be a symptom of other diseases involving gastrointestinal tract or colon/rectal cancer. It is important to see a doctor if you have any rectal bleeding.
You will be asked about your symptoms and medical history. A physical exam will be done. Your anus and rectum will be examined to look for swollen blood vessels. A digital rectal exam will be done. This is done by inserting a gloved, lubricated finger into the rectum to feel for abnormalities. Sometimes, it is necessary to do the exam with the use of an endoscope that allows the rectal canal and other parts of the colon to be viewed.
Initial medical treatment of hemorrhoids is aimed at relieving symptoms. Measures to reduce symptoms include:
- Sitz baths—sitting in plain, warm water 2-3 times a day for about 10 minutes each time
- Ice packs—putting cold packs on the anus for short periods of time to relieve pain and swelling
- Medication—applying hemorrhoidal creams or suppositories to the affected area
- High-fiber diet —eating more fresh fruit, raw or cooked vegetables, and whole grains has been shown to reduce hemorrhoid symptoms
- Fluids—drinking plenty of non-alcoholic fluids will help soften stools
If these treatments do not provide relief, one of several nonsurgical procedures may be used to shrink or destroy the hemorrhoidal tissue. These procedures, which are generally performed in a doctor’s office, include:
- Rubber band ligation —a rubber band is placed around the base of the hemorrhoid to cut off circulation and force the hemorrhoid to wither away within a few days
- Sclerotherapy—a chemical solution is injected near the blood vessel to cause scarring and shrinkage of the hemorrhoid
- Coagulation therapy—electricity, laser, or infrared light is used to shrink the hemorrhoidal tissue
If nonsurgical procedures are not an option or fail to resolve the problem, surgery may be needed.
Hemorrhoidectomy is the permanent removal of hemorrhoids by cutting the hemorrhoidal tissue away. Some of the newest surgical treatments involve using stainless steel staples. While many surgeons favor these treatments, there is some evidence that techniques that are more traditional produce more consistent and long-lasting relief.
