Can running or exercise make hemorrhoids worse or cause them not to heal?
Symptoms of hemorrhoids may sometimes be brought on by activity. Vigorous exercise, or any activity that causes exertion, straining, or bearing down (such as weight lifting, childbearing, or even straining to have a bowel movement) can cause hemorrhoids to swell. Exercise will not, however, cause a lasting negative change in the hemorrhoids. In other words, exercise may make symptoms temporarily worse, but the hemorrhoids will not permanently worsen. There is no reason to avoid exercise because of hemorrhoids, unless it causes symptoms that you find unacceptable.
Hemorrhoids are lumps of tissue in the anus. These lumps contain enlarged blood vessels. Hemorrhoids may be inside the anal canal ("internal hemorrhoids"), where they primarily cause sporadic bleeding, usually when having a bowel movement. Hemorrhoids may also lie outside the anal canal ("external hemorrhoids"), where they primarily cause swelling and sometimes discomfort. These symptoms may occur sporadically. Many people have both internal and external hemorrhoids.
Sometimes blood vessels in external hemorrhoids may clot (undergo "thrombosis"). This causes the sudden appearance of a firm lump (½ to 1 inch) at the anal opening. This may be quite painful. The underlying hemorrhoid may have been so small that the person never noticed it before. The hemorrhoid thrombosis usually goes away with time.
Hemorrhoids are not dangerous, so treatment is almost always optional. Minor symptoms can be relieved with home treatment. The most important treatment is a daily fiber powder (such as Metamucil). This keeps the stools soft. Also, soaking in warm water three times a day can help if there is swelling, inflammation or discomfort. Ointments, creams, and suppositories are less important.
Hemorrhoids don't actually "heal." They just have ups and downs in terms of the symptoms they cause. Nevertheless, if you see rectal bleeding, visit your doctor. This is to determine if the bleeding is only from hemorrhoids and not from something more serious, such as rectal cancer.
If hemorrhoid symptoms are persistent and bothersome despite home treatment, you may consider surgery (hemorrhoidectomy) or office treatment with rubber band ligation. Although this surgical removal of hemorrhoids is painful, it is effective. With rubber band ligation, a rubber band is slipped around the base of the hemorrhoid to cut off its circulation. Once it has been deprived of its vital blood supply, the banded hemorrhoid withers and falls off.
