Hemorrhoids Symptoms
Signs and symptoms of hemorrhoids may include:
- Painless bleeding during bowel movements — you might notice small amounts of bright red blood on your toilet tissue or in the toilet bowl
- Itching or irritation in your anal region
- Pain or discomfort
- Swelling around your anus
- A lump near your anus, which may be sensitive or painful
- Leakage of feces
But straining or irritation when passing stool can damage a hemorrhoid's delicate surface and cause it to bleed. Occasionally, straining can push an internal hemorrhoid through the anal opening. This is known as a protruding or prolapsed hemorrhoid and can cause pain and irritation.
External hemorrhoids are under the skin around your anus. When irritated, external hemorrhoids can itch or bleed. Sometimes blood may pool in an external hemorrhoid and form a clot (thrombus), resulting in severe pain, swelling and inflammation.
Hemorrhoids Causes
The veins around your anus tend to stretch under pressure and may bulge or swell. Swollen veins (hemorrhoids) can develop from an increase in pressure in the lower rectum. Factors that might cause increased pressure include:
- Straining during bowel movements
- Sitting for long periods of time on the toilet
- Chronic diarrhea or constipation
- Obesity
- Pregnancy
- Anal intercourse
- Low-fiber diet
Hemorrhoids Complications
Complications of hemorrhoids are rare but include:
- Anemia. Chronic blood loss from hemorrhoids may cause anemia, in which you don't have enough healthy red blood cells to carry oxygen to your cells. This may result in fatigue and weakness.
- Strangulated hemorrhoid. If blood supply to an internal hemorrhoid is cut off, the hemorrhoid may be "strangulated," which can cause extreme pain and lead to tissue death (gangrene).
