Hemorrhoids, also known as piles, are the dilatation, the stretching beyond normal dimensions of radicles of rectal veins inside the anal canal. In this instance a radicle is the smallest branch of a blood vein. Veins are weak compared to arteries due to their thin walls, therefore veins can become strained and twisted with any great back pressure. Veins have one-way valves to prevent back flow. The three rectal veins are named accordingly superior, middle and inferior rectal veins. Obstructions or pressure increase in these veins cause hemorrhoids.
Piles, or hemorrhoids, come in two types, internal and external. External hemorrhoids are outside the anus and are skin covered. Their color may be brown or black. Because nerves are so abundant in the anal area an external hemorrhoid is extremely painful.
The second type, internal hemorrhoids are in the interior of the anal canal, internal to the anus. They are purple or red and have a mucous membrane covering. They are usually painless. It isn’t unusual for a person to have both external and internal hemorrhoids at the same time.
Conditions that can lead hemorrhoids –
Hemorrhoids, a familial disease, tend to occur among members of a family, is sometimes blamed on heredity. The only animals that get hemorrhoids are those that stand on two legs. Most likely this is due to rectal vein congestion because of the pull of gravity. People who are chronically constipated often have piles problems. Resisting the urge to move your bowels at your body’s signal can bring about constipation and then hemorrhoids.
A high intake of meat, chicken, shrimp, spicy foods and more lead to hemorrhoids. The people least likely to get piles are those who have a high percentage of vegetables and fibrous food in their diet. Some women get hemorrhoids during pregnancy because of the uterus compressing the rectal veins. Rectal cancerous lesions might bring about hemorrhoids through obstructing blood flow. proctolab crema
Symptoms and indications of hemorrhoids –
With external hemorrhoids a protuberance can be seen and felt around the anus. There will be pain and discomfort in the anal area. While straining to expel a stool the pain will be worse.
Early on, internal hemorrhoids can’t be felt. Subsequently, in progression of the disease, the hemorrhoids will protrude as a stool is expelled and then retreat by themselves. When the condition worsens the protruded hemorrhoids won’t go back.
Bleeding isn’t unusual for either type hemorrhoid. However, when an internal hemorrhoid is retracted it could bleed internally, into the rectum. Bleeding occurs in splashes while pushing to expel a stool. In some cases the bleeding may be quite profuse. With both types of hemorrhoids there may be a mucus discharge and it will itch around the anus.
