5 Causes & Symptoms of Hemorrhoids – Diagnosis & Treatment

Hemorrhoids are structures within the anal canal that help with stool control. They basically aid in smooth passage of stool. This is made possible by their composition; they are composed of arterio-venous channels with connective tissues. Hemorrhoids are very necessary for continence and the protection of anal sphincter muscles during passage of stool. The presence of hemorrhoids in the anal canal is therefore normal and beneficial. It is only when hemorrhoids experience abnormal changes that they start causing problems. Problematic pathological) hemorrhoids are usually swollen or inflamed.

Types of Hemorrhoids

Pathological hemorrhoids are classified into two categories depending on their position within the anal canal.

External pathological hemorrhoids – External pathological hemorrhoids occur at the end of the anal canal. They are usually swollen, irritative and can be very painful. This is mainly because they are usually varicosities of the veins that drain the inferior rectal arteries. Left untreated, external pathological hemorrhoids can become thrombosed.

Internal pathological hemorrhoids – Unlike external pathological hemorrhoids, internal pathological hemorrhoids occur within the rectum. Because they are varicosities of veins that drain an area without pain receptors, internal pathological hemorrhoids do not cause any pain. They can however bleed if irritated. Left untreated, internal pathological hemorrhoids can develop into severe forms of hemorrhoids-prolapsed and strangulated hemorrhoids, which can be pushed outside the anus.

Treatment of Hemorrhoids
