Hemorrhoids are masses or lumps of tissues in the anus or rectum, which contain inflamed blood vessels. Any boost in abdominal pressure can produce hemorrhoids. It may be because of repeated straining for having a bowel movement, particularly in people who have frequent constipation, repeated episode of diarrhea, pregnancy, obesity; lots of patients have no clear explanation for formation of hemorrhoids, though. Internal hemorrhoids lie down in the anal canal, the place where they chiefly cause the symptoms of intermittent bleeding, generally with a bowel movement, and mucous discharge at times. They are painless usually. Internal hemorrhoids may protrude (prolapsed) also outside the anus, the place where they come into view as small, just grape-like masses. Generally the prolapsed hemorrhoid may be pushed back in the anus using your finger tip. The external hemorrhoids lie outside the anal’s opening, where they principally cause symptom of swelling or inconvenient protrusions, and at times discomfort. Discomfort and Swelling may occur only sporadically. External hemorrhoids also may cause difficulties keeping anal area fresh after bowel movement. External hemorrhoids at times build up a blood clot in them ("thrombosis"), habitually after a constipation or diarrhea. In this case, this produces an unexpected painful and firm lump or swelling around the brim of the anus.
Lots of patients suffer from internal and external hemroids both. Hemorrhoids are an extremely common health trouble. Hemorrhoids are more probable to build up in people who eat inadequate dietary fiber as well as don't get adequate exercise, which can result in repeated episode of constipation as well as straining to have the bowel movements.
