External Hemorrhoids – Causes and Treatment
Hemorrhoids refer to swollen veins which develop in the lower part of rectum and anus. These veins or walls of blood vessels stretch thinly, resulting in bulging of the veins, which causes irritation in them. This condition is referred to as piles. Difference between internal and external hemorrhoids Internal hemorrhoids occur deep inside the rectum and are not visible. In this condition, the pain is minimal since the presence of pain-sensing nerves is also negligible in this region. This kind of hemorrhoids can only be identified through bleeding, as and when it occurs. In contrast, external hemorrhoids are found in the skin which surrounds the anus area. This region has more pain-sensing nerves, and therefore, it tends to bleed more often. Causes of external hemorrhoids One of the most common causes of external hemorrhoids has been found to be straining while undergoing bowel movement. This condition develops when the vein of rectum gets dilated or enlarged. This condition develops when the person is experiencing severe diarrhea or constipation. Pregnant women also face the risk of hemorrhoids as they experience pressure from the uterus on their veins. How to recognize symptoms External hemorrhoids have a range of symptoms. These symptoms tend to vary according to the severity of hemorrhoids.
