Hemorrhoids or piles are pathologically changed blood vessels located around the anus. The problem arises when these structures become inflamed or swell. Depending on the position, hemorrhoids may be internal and external.
Symptoms usually include itching, rectal pain and bleeding and they subside in several days. Internal hemorrhoids are often presented as red blood covering the stool and this is known as hematochezia. This type of hemorrhoids rarely causes any pain, unless they are severely damaged. Thrombosis or necrosis of these hemorrhoids may cause some pain. External hemorrhoids cause significant amount of pain to the patients suffering from this problem. There is less or no bleeding involved, but the lumps and swelling around the anus is sometimes extremely painful for the person.
Doctors have identified certain factors which may contribute to the development of hemorrhoids. Irregular bowel habits, including both diarrhea and constipation, lack of fibers in the diet, physical inactivity and sedentary way of life, as well as genetic predisposition are some of these factors. Absence of valves within the hemorrhoidal veins, increased rectal vein pressure or increased intra-abdominal pressure because of the strain may also contribute to hemorrhoids. Pregnancy and age are also found to be important factors. Pregnant women frequently experience troubles with hemorrhoids, but most of them resolve on their own, without the need for surgical intervention.
As the treatment, specialists recommend increasing intake of fibers through the food and propped hydration of the body. For the pain, doctors usually advise taking some non-steroidal anti-inflammatory drugs (NSAIDs). Plenty of rest and sitz baths may also help, but if there is nothing that seems to give good results, there are some surgical procedures.
As already mentioned, hemorrhoids may bleed, especially if you happen to suffer from internal hemorrhoids. It doesn’t have to last for a long time but patients have been reporting hemorrhoids bleeding for several weeks.
The most common cause of this problem is the pressure exerted to the anus. It can happen if you are standing or sitting for a long period of time, but it usually happens when the person is going to the toilet. Added pressure on hemorrhoids in that situation causes bursting and bleeding. Since this is something happening every single day, there is no chance for hemorrhoids to heal and so they can they bleed for several weeks.What you need to learn is how to evacuate on the toilet and not to cause damage to your already problematic hemorrhoids. Once you learn to do so, the healing process will start and hemorrhoids may never return.
