What Is Hemorrhoids?

A hemorrhoid is a varicosity in the inferior rectum or anus caused by an obstruction in the veins of the hemorrhoidal plexus.  Anatomically, the hemorrhoidal plexus is created by the veins of the rectal submucous membrane, structured in the internal and external hemorrhoidal plexus, situated under the pectineal line. Hemorrhoid symptoms typically depend on the location.  Internal hemorrhoids lie inside the rectum, above the internal sphincter of the anus.  Usually, you cannot see or feel these hemorrhoids because they normally don't cause discomfort.  However, straining or irritation when passing stool can damage a hemorrhoid's delicate surface and cause it to bleed.  Moreover, if they become large enough to protrude from the anal opening, they become constricted, irritated and painful.  These small internal hemorrhoids may bleed upon defecation.  On the other hand, the external hemorrhoids home treatment canappear outside the anal sphincter.  This type of hemorrhoids is commonly not painful and bleeding is rare unless, otherwise, a hemorrhoidal vein ruptures.  Additionally, hemorrhoids can build up from any increase in pressure in the veins in the inferior area of the rectum.  Most common causes of hemorrhoid cases include diarrhea due to continuous loose stools expulsion, constipation and its’ associated straining of bowel, obesity, pregnancy, and sitting for a long period of time.  External hemorrhoids can be diagnosed by a physician, simply by just looking.  For internal hemorrhoids, manual rectal examination using a rubber-gloved finger will be conducted.  Frequent follow-up is necessary and continued rectal bleeding despite compliance to hemorrhoid home treatment, requires additional tests and examinations.
