External hemorrhoids can be seen or felt easily around the anal opening. When the swollen veins are scratched or broken by straining or rubbing, they bleed. Veins in the rectum and around the anus tend to expand under pressure. Hemorrhoids can result from too much pressure on these veins. Flare-ups of hemorrhoids may occur during periods of stress or as a result of overuse of alcohol.
Some people inherit a tendency to have hemorrhoids.
Your health care provider will examine your rectum and anus. He or she may use a lighted viewing tool called a proctoscope or anoscope to look inside the rectum. Fluids Drink plenty of fluids, especially water. Fluid helps to soften bowel movements so they are easier to pass. Sitz baths and cold packs Sitting in lukewarm water 2 or 3 times a day for 15 minutes cleans the anal area and may relieve discomfort.
