Characteristics of
hemorrhoids (piles)
There are two kinds!?
What are hemorrhoids (piles)?
As the name implies, hemorrhoids (piles) are wart-shaped swellings on the anus. The piles that form on the inside of the anus across the dentate line are called internal hemorrhoids, whereas the ones that form outside are called external hemorrhoids.
These mostly form due to excessive pushing during bowel movements or constipation, which puts pressure on the anus, restricting blood circulation around the anal canal, congesting blood in the capillaries of the venous plexus and causing swelling. The symptoms of the hemorrhoids (piles) differ when they are formed in a different location.
Internal hemorrhoids are wart-shaped swellings that are formed by blood congestion in the venous plexus above the dentate line and below the mucous membrane due to pressure during bowel movements. Because there are no sensory nerves (nerves that feel pain) passing through the tissues in this area, many people have very little pain, only realizing they have hemorrhoids when they notice bleeding. In some cases, you may bleed so much that the toilet becomes bright red. If symptoms progress, hemorrhoids may come out of the anus during bowel movements, and inflammation can occur, resulting in pain.
External hemorrhoids are wart-shaped swellings that are formed by blood congestion in the venous plexus of the skin below the dentate line due to pressure during bowel movements. Because sensory nerves (nerves that feel pain) pass through the skin outside the anus, most external hemorrhoids cause pain.
They can also become suddenly inflamed, causing thrombi (blood clots) and significant swelling, resulting in severe pain.
Furthermore, incarcerated hemorrhoids and external thrombosed hemorrhoids can cause severe pain.
