Hemorrhoids are swollen veins. They are found in and around the anus and lower rectum. External hemorrhoids grow under the skin around the anus. Internal ones grow inside the anus.

The exact cause not known. It may be due to:
- Chronic constipation that results in straining during bowel movements
- A buildup of pressure or fluid inside the belly, such as from pregnancy or health problems
This problem is more common in older adults. Other things that may raise the risk are:
Some people may not have symptoms. Others may have problems that range from mild to severe. Common ones are:
Bleeding, which may be seen:
- On stool
- On toilet paper
- In the toilet bowl
- Anal itching and burning
- Swelling and pain during bowel movements
- Sensitive lumps around the anus
The doctor will ask about your symptoms and health history. A physical exam may be done. It will focus on the anal area. An anoscope may be used to see internal structures. This is often enough to make the diagnosis.
The goal of treatment is to ease symptoms and promote healing.
Initial treatments may be:
- Supportive care, such as warm baths or cold packs
- Lifestyle changes, such as a high-fiber diet and drinking plenty of fluids
Medicines to ease pain, such as:
- Ointments, creams, and suppositories applied to the skin
- Over the counter pain relievers taken by mouth
Procedures may be done when other methods are not helpful. Options are:
- Rubber band ligation—places a rubber band around the base of the hemorrhoid to cut off blood flow to it until it withers away
- Sclerotherapy—injects a chemical mix near the vein to scar and shrink the vein
- Coagulation therapy—uses electricity, laser, or infrared light to shrink the tissue
- Hemorrhoidectomy—uses surgery to remove the hemorrhoid
To lower the risk of this problem:
- Do not strain or read while having a bowel movement.
- Treat constipation.
- Drink plenty of fluids during the day.
- Eat a high fiber diet.
