Hemorrhoids, also called piles, are swollen and inflamed veins in your anus and lower rectum. Hemorrhoids may result from straining during a bowel movement or from the increased pressure on these veins during pregnancy, among other causes.
A sometimes embarrassing topic of discussion, hemorrhoids are one of the most common ailments. By age 50, about half of adults have had to deal with the itching, discomfort and bleeding that can signal the presence of hemorrhoids.
Fortunately, many effective options are available to treat hemorrhoids. Most people can get relief from symptoms using home treatments and lifestyle changes.

Signs and symptoms of hemorrhoids may include:
Hemorrhoid symptoms usually depend on the location. Internal hemorrhoids lie inside the rectum. You can't see or feel these hemorrhoids, and they usually don't cause discomfort. But straining or irritation when passing stool can injure a hemorrhoid's delicate surface and cause it to bleed. Occasionally, straining can push an internal hemorrhoid through the anal opening. This is known as a protruding or prolapsed hemorrhoid and can cause pain and irritation.
External hemorrhoids are under the skin around your anus. When irritated, external hemorrhoids can itch or bleed. Sometimes blood may pool in an external hemorrhoid and form a clot (thrombus), resulting in severe pain, swelling and inflammation.
When to see a doctor
Bleeding during bowel movements is the most common sign of hemorrhoids. But rectal bleeding can occur with other digestive diseases, including colorectal cancer and anal cancer. Don't assume that bleeding is coming from hemorrhoids without consulting a doctor. Your doctor can do a physical examination and perform other tests to diagnose hemorrhoids and rule out more serious conditions or diseases. You should also seek medical advice if your hemorrhoids cause pain, bleed frequently or excessively, or don't improve with home remedies.
If your hemorrhoid symptoms began along with a marked change in bowel habits or if you're passing black, tarry or maroon stools, blood clots or blood mixed in with the stool, consult your doctor without delay. These types of stools can signal more extensive bleeding elsewhere in your digestive tract.
Seek emergency care if you experience large amounts of rectal bleeding, lightheadedness, dizziness or faintness.

The veins around your anus tend to stretch under pressure and may bulge or swell. Swollen veins — hemorrhoids — can develop from an increase in pressure in the lower rectum. Factors that might cause increased pressure include:
It's also possible to inherit a tendency to develop hemorrhoids. Hemorrhoids are more likely as you get older because the tissues that support the veins in your rectum and anus can weaken and stretch with aging.

Because talking about hemorrhoids can be embarrassing, many people are reluctant to see a doctor about the condition. But it's a good idea to consult a doctor any time you experience rectal bleeding, to make sure you don't have a more serious digestive disease. Start by talking to your regular doctor. If you have other signs and symptoms, such as a change in bowel habits or abdominal pain, your doctor may refer you to one or more specialists. These might include a doctor with expertise in the digestive system (gastroenterologist) or a colon and rectal surgeon, for evaluation and treatment.
You can help your doctor by being prepared with as much information as possible. Here are some suggestions to help you get ready for your appointment.
What to expect from your doctor
Your doctor may ask:

Your doctor may be able to see if you have external hemorrhoids simply by looking. For internal hemorrhoids, he or she will insert a rubber-gloved finger into your rectum. Because internal hemorrhoids are often too soft to be felt in a rectal examination, your doctor may also examine the lower portion of your colon and rectum with an anoscope, proctoscope or sigmoidoscope. These are flexible, lighted tubes that allow your doctor to see into your anus and rectum.
Your doctor may want to do a more extensive examination of your entire colon using colonoscopy. This might be recommended if:

Most of the time, treatment for hemorrhoids involves steps that you can take on your own, such as lifestyle modifications. But sometimes medications or surgical procedures are necessary.
Medications
If your hemorrhoids produce only mild discomfort, your doctor may suggest over-the-counter creams, ointments, suppositories or pads. These products contain ingredients, such as witch hazel or hydrocortisone, that can relieve pain and itching, at least temporarily.
Don't use an over-the-counter cream or other product for more than a week unless directed by your doctor. They can cause side effects, such as skin rash, inflammation and skin thinning.
Minimally invasive procedures
If a blood clot has formed within an external hemorrhoid, your doctor can easily remove the clot with a simple incision, which may provide prompt relief.
For persistent bleeding or painful hemorrhoids, your doctor may recommend another minimally invasive procedure. These treatments can be done in your doctor's office or other outpatient setting.
Surgical procedures
If other procedures haven't been successful or you have large hemorrhoids, your doctor may recommend a surgical procedure. Surgery can be performed on an outpatient basis or you may need to stay in the hospital overnight.

You can temporarily relieve the mild pain, swelling and inflammation of most hemorrhoidal flare-ups with the following self-care measures:
These self-care measures may relieve the symptoms, but they won't make the hemorrhoid disappear. See your doctor if you don't get relief in a few days, or sooner if you have severe pain or bleeding.
