Hemorrhoids are inflamed and swollen veins in the lower rectum or around the anus. Rectum is the last part of large intestine and anus opens at the end of digestive tract. External hemorrhoids can be found under the skin around anus and internal hemorrhoids in the lower rectum.
The internal hemorrhoids may prolapse or protrude through anus. Most of the internal hemorrhoids are painless and they shrink back inside the rectum. However, severely prolapsed hemorrhoids protrude permanently and they can cause itching, discomfort, pain, etc. Increased pain in internal hemorrhoidal veins is the major cause of internal hemorrhoids. It also occurs due to constipation, diarrhea, sitting for a long period, aging, pregnancy, anal intercourse, obesity, cirrhosis, low fiber high fat diet, etc. (For further information on hemmorrhids, please click this link Hemmorrhids)
Bright red blood on stool, in toilet bowl or toilet paper is one of the major hemorrhoid symptoms. Patients will not feel any pain if the internal hemorrhoids are not prolapsed. The prolapsed hemorrhoids cause discomfort, pain and anal itching. There is also a chance to clot blood in external hemorrhoids. If the blood clot is formed in the vein, it is called thrombosis. These thrombosed external hemorrhoids cause painful swelling, bleeding, and a hard lump around anus. Extra skin is left behind after dissolving blood clots. This skin becomes itchy or irritated. Excessive straining, cleaning or rubbing around anus can make symptoms such as irritation and itching.
Internal Hemorrhoid Treatment
Hemorrhoids are not life threatening or dangerous and the hemorrhoid symptoms go away in a few days. However, immediate medical care is essential if there is abnormal bleeding from anus or rectum, inflammatory bowel disease, weakness, lightheadedness, thrombosed external hemorrhoids, etc.
Internal Hemorrhoids can be diagnosed by conducting physical examinations, observing hemorrhoid symptoms, etc. Colonoscopy, sigmoidoscopy, barium enema X-ray, etc are also used for diagnosing this disease. Internal hemorrhoid treatment includes both home remedies and medicinal cures. The swelling and other hemorrhoid symptoms can be cured by changing lifestyle and diet. Fiber rich diet helps to make stools soft. So the bowl movement becomes easy and it also reduces the pressure on hemorrhoids. Fiber is also essential for preventing constipation and improving digestion. Whole grains, vegetables, fruits, etc are good sources of dietary fiber. According to the American Dietetic Association, man should consume 38 grams fiber per day and woman should 25 grams. Drinking lots of water, sitting in a tub of warm water for few minutes, doing exercise, etc are the other home remedies for internal hemorrhoids treatment. Inflammation and itching can be reduced by applying some suppositories and creams. Local anesthetics such as benzocaine, benzyl alcohol, tetracaine, pramoxine, etc are used for getting relief from itching, burning and pain. If applied in anus, Vasoconstrictors help to make blood vessels smaller. Protectants such as aluminum hydroxide gel, cocoa butter, glycerin, kaolin, lanolin, mineral oil, starch, white petrolatum, cold liver oil, zinc oxide, etc are used for preventing irritation in perianal area. Doctors can also prescribe some antiseptics such as boric acid, hydrastis, phenol, benzalkonium chloride, etc for treating hemorrhoid symptoms. Astrigents, keratolytics, analgesics, corticosteroids, etc are also effective for internal hemorrhoid treatment.
Hemorrhoid removal can be done by conducting various surgical procedures such as rubber band ligation, sclerotherapy, infrared coagulation, laser therapy, stapled hemorrhoidectomy and hemorrhoidectomy. Hemorrhoid removal is used for patients with chronic piles.
