Ever wonder how long food takes to leave the body? Well, under good conditions, within 8 to 10 hours, food has passed through the small intestine and is mostly digested when it then enters the final digestive process.
The colon contains 6 sections called: the cecum, ascending colon, transverse colon, descending colon, sigmoid and rectum. Situated at the extreme end of the cecum is the worm-like organ called the appendix. It's about 3 inches long and is often the source of inflammation because of lodged food and bacteria causing painful appendicitis.
The colon, unlike the small bowel, has a mucous lining or membrane which is smooth and contains no villi. Surrounding thus mucous layer is a muscular coating consisting of circular internal muscles and longitudinal external muscles s found in the small bowel. The colon is shaped into bulbous pouches called haustras. Haustras are composed of muscles which contract to gather the colon up into a puckered appearance and which allow for a great deal of expansion.
The colon ends in the rectum and anus, the exterior opening where elimination takes place. The anus is held closed by the anal sphincter muscle.
The lining of the rectum contains mucus and is striated in length-wise segments giving a fluted appearance. Generally the nerve supply to the colon is not prolific and therefore sensory impulses are very weak. Colonic activity is unfelt for the most part, as a result. An exception is found in the rectum where nerve endowment is greater and thus there is the pain associated with hemorrhoids and other tears and fissures.
There are basically four types of hemroids that is internal, external, prolapsed and bleeding hemorrhoids
Internal hemroids occur inside the anus and rectum, from where they can cause a lot of uneasiness and inflammation.
External hemroids appear on the outside of the anus, especially around the anal opening. They too can cause a lot of discomfort because of constant friction with clothes, etc.
Prolapsed hemroids basically represent a later stage in the development cycle of internal hemroids. When the latter become too bulky due to clogging of the veins with blood they begin to sag and consequently protrude from the anus.
Bleeding hemroids are also a more severe form or stage of internal hemorrhoids characterized by profuse bleeding.
How can hemroids be treated?
There are several methods of treating hemorrhoids and they include temporary remedies as well as longer lasting ones. The common ones are:
Band Ligation
This method of treating hemorrhoids involves blocking the flow of blood to the excessive growth or lump using a rubber band. Your medical practitioner will show you how.
Injection Therapy
This method involves injecting the affected area with hardening agents which stop circulation and reduce the size of the hemroids. It is good for treating multiple hemorrhoids.
Coagulation
This method is recommended for treating small hemorrhoids. It involves using electric current or infrared light to burn off the hemorrhoids. With continuous treatment hemorrhoids shrink and finally disappear.
Hemroids surgery
A surgical operation is used to remove the hemorrhoids while the patient is under anesthesia.
Creams and other medical products
There are a number of creams and other medications available on the market for the treatment of hemorrhoids. Your medical practitioner will guide you accordingly regarding which ones are best for your type of hemroids.
