General Info Concerning Internal Hemorrhoids
Hemorrhoids are anatomically defined as, "the blood vessel-filled tissue at the end of the anus and the rectum." If used in the popular sense of, "I have hemorrhoids," the phrase refers to vein varicosities in the hemorrhoids, which is to say inflamed, tangled and/or enlarged veins in the tissue at the end of the rectum and the anus. Perianal hematoma, which is actually bruising caused by ruptured veins inside the perianal tissue, can be mistaken for and misdiagnosed as hemorrhoids. The treatment for hemorrhoids is different compared with the treatment for perianal hematoma. This text would look at internal hemorrhoids.
There are two kinds of hemorrhoids, internal and external. For our purposes, we shall define internal hemorrhoids as, "varicosities (swollen, knotted and/or enlarged veins) in the hemorrhoid tissue in the rectum."
Hemorrhoid tissue inside the rectum drains the area of the superior rectal arteries. The tissue in this specific region does not have pain receptors. So, internal hemorrhoids typically go unnoticed unless irritated, at which time they may bleed. Sometimes different rectal problems are incorrectly identified as hemorrhoids. Conditions that could create hemorrhoid-like signs and symptoms include abscesses, anal irritation, itching or melanoma, fistulae, and fissures.
Internal hemorrhoids are not life threatening or dangerous. Slight hemorrhoid signs and symptoms often resolve in just a few days. Many people with hemorrhoids don't manifest symptoms. For many, their first sign of hemorrhoids is blood on the stool, toilet paper or in the bowl. When a swollen internal hemorrhoid is forced outside the anus, generally during defecation, it's called a protruding hemorrhoid. With hemorrhoids, rubbing and washing of the anus makes matters worse. The irritation can lead to a series of symptoms.
Without correct treatment internal hemorrhoids may worsen to prolapsed hemorrhoids or even strangulated hemorrhoids. A prolapsed hemorrhoid is a protruding internal hemorrhoid that is outside the anus even when the anus is closed. Note the progression: from an internal hemorrhoid to a protruding hemorrhoid and then into a prolapsed hemorrhoid.
The final stage is a strangulated hemorrhoid. This happens when the sphincter, attempting to rid itself of the irritant of the prolapsed hemorrhoid, becomes spastic. The muscle spasm cuts off the blood supply to the veins within the hemorrhoid, strangling it.
The Banov grading system is the most common means of classifying hemorrhoids by severity. Under the Banov system, hemorrhoids are graded on a scale of 1 to 4. A grade 1 hemorrhoid does not protrude - that is, it is a true internal hemorrhoid. Grade two hemorrhoids protrude out of the anus when defecation is taking place, but spontaneously diminish with the removal of muscle tension and withdraw to an interior position. Grade 3 hemorrhoids have to be manually reduced (squeezed) once defecation is complete to allow to withdraw within the anus. Grade 4 hemorrhoids call for surgery as they're external to the body and cannot be manually reduced.
Internal hemorrhoids can be caused by persistent constipation, diarrhea, portal hypertension, obesity, poor muscular tone, poor stance and pregnancy. Extreme consumption of alcohol or caffeine is thought to at least aggravate hemorrhoids.
Causes And Treatment Of Internal Piles
Hemorrhoids are classed as either internal or external. All hemorrhoids start as an internal hemorrhoid. At their worst, hemorrhoids protrude out the anus even when the muscle is closed.
A Simple Definition Of External Hemorrhoids
This is a discussion of the symptoms and progression of external hemorrhoids. Not all external hemorrhoids are correctly diagnosed and many are actually distended internal hemorrhoids. The true external hemorrhoid has its source in the exterior of the anal verge.
Basic Facts About External Hemorrhoids
There are two types of external hemorrhoids:Type I external hemorrhoids protrude from the area around the outside of the anus. Type 2 external hemorrhoids are interior hemorrhoids that protrude outside the anus. This article concerns external hemorrhoids, and will discuss both types.
