Hemorrhoids Questions & Answers
What Are Hemorrhoids?
Hemorrhoids, also known as piles, are the result of swollen inflamed veins in the anus and rectum. They have the appearance of lumps of tissue within the anal canal that contain blood vessels and tissue including muscle and elastic fibers.
Similar to varicose veins, blood vessels can become unusually swollen in the rectal area. Hemorrhoids can range in size from the size of a raisin to the size of a grape. They can be internal or sometimes protrude through the anus.
The Anatomy of Hemorrhoids
Arteries round the anal canal form a complex network known as hemorrhoidal blood vessels. These supply arterial blood to the surrounding area. The blood vessels that supply the hemorrhoidal vessels pass through the supporting tissue of the hemorrhoidal cushions.
Although many people think hemorrhoids are abnormal, they are present in everyone. It is only when the hemorrhoidal cushions enlarge that hemorrhoids can cause problems and are considered abnormal or a health problem.
Prevalence of Hemorrhoids
Although hemorrhoids occur in everyone, they become large and cause problems in only 4 percent of the general population. Hemorrhoids that cause problems are found equally in men and women, and their prevalence peaks between 45 and 65 years of age.
Who Suffers from Hemorrhoids
Statistics indicate that up to 10 million people in the United States suffer from hemorrhoids. This means that almost 4% of the population have to endure the pain, discomfort and embarrassment of this condition. Over 1.5 million prescriptions are handed out by doctors for medical treatment.
The number of people requiring surgical treatment (hemorrhoidectomies) has sharply decreased in the past 30 years. This partly is due to improvements in the available treatments and better awareness levels of self help/ health issues.
For he majority of hemorrhoid sufferers the condition manifests between the ages of 45-65 years old.
Overview of Causes
Straining and constipation have long been thought of as culprits in the formation of hemorrhoids. This may or may not be true. Patients who report hemorrhoids have a canal-resting tone that is higher than normal. Of interest, the resting tone is lower after hemorrhoidectomy than before. This change in the resting tone is the mechanism of action of Lord dilatation, which is most commonly performed in the United Kingdom.
Pregnancy clearly predisposes women to symptoms from hemorrhoids, although the etiology is unknown. Notably, most patients revert to their previously asymptomatic state after delivery. The relationship between pregnancy and hemorrhoids lends credence to hormonal changes or direct pressure as the culprit
