Hemorrhoids, also called "piles," are swollen tissues that contain veins. They are located in the wall of the rectum and anus and may cause minor bleeding or develop small blood clots. Hemorrhoids occur when the tissues enlarge, weaken, and come free of their supporting structure. This results in a sac-like bulge that extends into the anal area. This is a unique disease because no other animal can get this, up to 86% of people would say that they have had Hemorrhoids at some time throughout their life. They can be painful and annoying but aren't usually serious. Hemorrhoids differ depending on their location and the amount of pain, discomfort, or aggravation they cause. Internal hemorrhoids are located up inside the rectum. They rarely cause any pain, as this tissue doesn't have any sensory nerves. These hemorrhoids are graded for severity according to how far and how often they protrude into the anal passage or protrude out of the anus. Grade I is small without protrusion. Painless, minor bleeding occurs from time to time after a bowel movement. A grade II hemorrhoid may protrude during a bowel movement but returns spontaneously to its place afterwards. In grade III, the hemorrhoid must be replaced manually. A grade IV hemorrhoid has prolapsed it protrudes constantly and will fall out again if pushed back into the rectum. There may or may not be bleeding. Prolapsed hemorrhoids can be painful if they are strangled by the anus or if a clot develops. Other factors that increase the risk for getting hemorrhoids include constipation, diarrhea, lifting heavy objects, poor posture, prolonged sitting, pregnancy, eating a diet low in fibre, anal intercourse, and being overweight. Liver damage and some food allergies can also add stress to the rectal veins.
I chose this disease because it randomly popped up and I find things like this very interesting. Our bowel movement is very important to our Digestive System, that is why when this topic popped up I had to write about it. This relates to our topic because Ms. Phillips has shown us pretty neat videos like this and I think its good to learn different things every day.
