Hemorrhoids (Piles) Overview
Popular speaking, hemorrhoids are the venous congestion masses that induced by the disturbance of anal blood circulation in fact.The term hemorrhoids refers to a condition in which the veins around the anus or lower rectum are swollen and inflamed. There are two kinds of hemorrhoids:
Internal hemorrhoids: usually don't hurt or itch; you can't feel them because they are deep inside the rectum. Internal hemorrhoids are pretty harmless. But since their bleeding could mask blood from a dangerous source like colorectal cancer, they should be treated.
External hemorrhoids: cause most of the symptoms we commonly hear about --- pain, burning, and itching. If an external hemorrhoid becomes strangulated (cut off from blood supply), a clot can form in it and become an excruciatingly painful thrombosed hemoroid. Because of these unpleasant symptoms, external hemorrhoids get the most treatment attention.
Hemorrhoids Causes
Hemorrhoids are caused by pressure on the veins in the rectum and anus. hemorrhoids are called human patents, because only humans are the senior upright-walking vertebrates. Many factors, e.g. the vertical gravitation of the earth to human anal blood vessel, the constant fatigue during working, illness and diet can cause the anal venous drainage impeded, muscle tension relaxed, blood vessel elasticity decreased and vein congestion masses assembled, thus hemorrhoids are caused.Listed below are the most frequent causes of hemorrhoids:
Hemorrhoids Symptoms
Hemorrhoids usually are not dangerous or life threatening. In most cases, hemorrhoidal symptoms will go away within a few days.
Although many people have hemorrhoids, not all experience symptoms. The most common symptom of internal hemorrhoids is bright red blood covering the stool, on toilet paper, or in the toilet bowl. However, an internal hemorrhoid may protrude through the anus outside the body, becoming irritated and painful. This is known as a protruding hemorrhoid.
Symptoms of external hemorrhoids may include painful swelling or a hard lump around the anus that results when a blood clot forms. This condition is known as a thrombosed external hemorrhoid.
In addition, excessive straining, rubbing, or cleaning around the anus may cause irritation with bleeding and/or itching, which may produce a vicious cycle of symptoms. Draining mucus may also cause itching.
Hemorrhoids Treatment
The common traditional therapies for hemorrhoids are: traditional surgical therapy, ultra-low and ultra-high temperature surgery therapy, drinking medicine, external medicine and medicine sticking therapy etc. Their shortcomings are: rapid recurrence, slow effect, high cost, with side effects, body hurts and may cause sequels etc.
You can relieve pain, itching, and swelling by using over-the-counter ointments, creams, and suppositories. You can also relieve pain and swelling with ice packs or warm water soaks. Larger internal hemorrhoids are treated with a variety of non-surgical and surgical techniques. Banding, or rubber band ligation, involves placing a tight band around the hemorrhoid. If there is a blood clot in the hemorrhoid, the doctor may cut the hemorrhoid open and remove the clot. Because the band cuts off the hemorrhoid’s blood supply, the vein withers and falls off within a few days. This procedure is usually painless. Internal hemorrhoids can also be injected with a chemical that will cause them to shrink, or destroyed with infrared light, a laser, an electrical current, or freezing with liquid nitrogen (cryosurgery). A hemorrhoidectomy is performed when hemorrhoids are severe and other treatments are not effective. Patients having a hemorrhoidectomy are given either spinal or general anesthesia. Then, the doctor inserts a lighted viewing tube, such as an anoscope, into the rectum and removes the hemorrhoids and any extra tissue around them.
