Among the common symptoms of hemorrhoids is thrombosis.
Understanding what a thrombosed external hemorrhoids is and how to best treat them can be a little bit of a mystery. A refresher course on human physiology can help to clear up any misunderstandings about what is involved with this condition.
The first thing to understand is that the word hemorrhoid refers to the vascular structures in the anal canal that help to control the movement of stool through the canal.
When we talk about hemorrhoids then, we are talking about a system of blood vessels that surround the anal canal.
Everyone has hemorrhoids, and complications that arise from these useful and necessary structures in the anal canal are very common. In fact it is thought that at least 50% of the population will have some kind of difficulty with their hemorrhoids during their lifetime.
The second thing to understand is that because we are dealing with blood in these structures, we are subject to some of the issues that determine how successful the blood is at traveling through the veins in the hemorrhoids.
The human circulatory system is made up of many thousands of blood pathways or veins in varying sizes and lengths that help to facilitate the moving of the blood throughout the body.
This provides for the delivery of life giving nourishment and maintenance to the cells. This miracle liquid we call blood is comprised of many substances that allow it to carry out numerous needed functions in the body in addition to providing nourishment to the cells.
One of the amazing things about blood is that it has the ability to build a dam or blockage at the site of any opening in the blood vessels to help keep the blood from leaking out.
This is an outstanding characteristic when one has a cut or a scrape but this attribute is also one that can lead to problems in the lower regions of the anal canal and rectum.
Certain conditions such as inadequate blood flow, trauma or injury to the vessel wall, or blood that is for some reason too thick or viscous, can result in blockage to the veins in the hemorrhoids.
The third thing to understand is that when this blockage occurs it is referred to as a thrombus or clot. Thrombosis is a serious condition because of the risk of further complications from the lack of blood movement through the area.
Some of the complications that might result from a thrombosed external hemorrhoid are bacterial infection which could cause the thrombus to break down and spread the infection throughout the circulatory system, or the thrombus could become detached and enter the circulatory system as an embolus or free floating clot, which might lodge elsewhere in the body and completely obstruct the flow of blood in that location.
Often times the thrombus will attach itself to other thrombi and become a fibrous tissue which the blood vessel will then form a new canal around.
It is obvious that a thrombosed external hemorrhoid is not a good condition to have and a course of action should be taken that will lead to the eventual removal of the hemorrhoid and the return to normal function of the circulatory system in the effected area.
