Pictures of Hemorrhoids Piles

If the Hemorrhoids originates at the top (rectal side) of the anal canal, it is referred to as an internal Hemorrhoids. If it originates at the lower end of the anal canal near the anus, it is referred to as an external Hemorrhoids. Technically, the differentiation between internal and external Hemorrhoids is made on the basis of whether the Hemorrhoids originates above or below the dentate line (internal and external, respectively).

As discussed previously, Hemorrhoidsal cushions in the upper anal canal are made up of blood vessels and their supporting tissues. There usually are three major Hemorrhoidsal cushions oriented right posterior, right anterior, and left lateral. During the formation of enlarged internal Hemorrhoids, the vessels of the anal cushions swell and the supporting tissues increase in size. The bulging mass of tissue and blood vessels protrudes into the anal canal where it can cause problems. Unlike with internal Hemorrhoids, it is not clear how external Hemorrhoids form.

What are the causes of Piles ? 

• It can be hereditary with congenital weakness of the vein walls.
• In men, due to erect posture there is high pressure in rectal veins.
• Straining by constipation and over purgation.
• Dysentery may aggravate latent Hemorrhoids.

Hemorrhoids are also common among pregnant women. The pressure of the foetus in the abdomen, as well as hormonal changes, cause the Hemorrhoids vessels to enlarge.
