Internal hemorrhoids are enlarged (varicose) veins in the wall of the anus, usually a consequence of prolonged constipation, dehydration, improper diet, exercise, medications, pregnancy, obesity, diarrhea, and some diseases like diabetes, thyroid, or heart disease. Some of the symptoms can include bleeding, itching, pain, and protrusion of external hemorrhoids.
There are four degrees of hemorrhoids.
First-degree or internal hemorrhoids always remain inside the anal canal, and the only symptom is bleeding after a bowel movement. Hemorrhoids that protrude outside the rectum during defecation as a swelling causing discomfort then go back inside on their own are second-degree hemorrhoids. Third-degree hemorrhoids protrude, and need help with pressure, or pushing back into the anal canal. The hemorrhoids that remains outside anal cavity are fourth-degree or external hemorrhoids.
Treatments for hemorrhoids.
First- and second-degree hemorrhoids may respond to bowel regulation using a high-fiber diet with stool softening products. If bleeding persists, a sclerosing fluid may be injected around the hemorrhoid to make them shrivel up. Forceful dilation of the anus under general anesthesia is also effective. Other procedures might include rubber band ligation, heat, laser or infrared light to shrivel up the hemorrhoids. The fourth-degree requires surgical removal.
