Definition:
Hemorrhoids are varicosities or swelling and inflammation of veins in the rectum and
anus. Hemorrhoids are actually the anatomical term for "'Cushions of tissue filled with blood vessels at the part of the rectum and the anus." However, the term has come into usual usage to indicate the condition described herein.q
Diagnosis:
Perianal hematoma are sometimes misdiagnosed and mislabeled as hemorrhoids, when in fact they have different causes and treatments.
Treatment:
Prevention of hemorrhoids includes drinking more fluids, eating more dietary fiber (such as fruits, vegetables and cereals high in fiber), exercising, practicing better posture, and reducing bowel movement strain and time. Hemorrhoid sufferers must avoid using laxatives and should strictly limit time straining during bowel movement.
Symptoms and Signs:
Although several people have hemorrhoids, not all experience symptoms. The most usual symptom of internal hemorrhoids is bright red blood covering the stool, on toilet paper, or in the toilet bowl. An internal hemorrhoid can protrude through the anus outside the body, becoming irritated and painful. This is considered as a protruding hemorrhoid.
Symptoms of external hemorrhoids can include painful swelling or a hard lump around the anus that results when a blood clot forms. This condition is also known as a thrombosed external hemorrhoid.
Causes:
Increased straining during bowel movements, by constipation or diarrhea, may lead to hemorrhoids. It is usual condition due to constipation caused by water retention in women experiencing premenstrual syndrome or menstruation.
Hypertension, particularly portal hypertension, can also cause hemorrhoids because of the connections between the portal vein and the vena cava which occur in the rectal well known as portocaval anastomoses
