What Are Hemorrhoids?
Hemorrhoids are painful veiny lumps that develop around the anus. They form due to pressure on the veins around the rectum and pelvis area. You can have either external or internal hemorrhoids (or both). Internal hemorrhoids develop inside of the anus, while external ones grow outside of the opening. Both are extremely painful. You can clearly tell when you have external hemorrhoids because you can see or feel them bulging from the anal area. If you see blood, or mucus, in your stool or the toilet after going to the bathroom, that is a possible sign of internal hemorrhoids.
Causes
Straining when having a bowel movement mostly causes hemorrhoids. Pushing hard to expel feces causes those veins to enlarge and become swollen. So if you have ongoing issues with constipation, this could be a chronic issue. Having a baby can also cause hemorrhoids because the mother must strain to push out her baby. Sitting for long periods of time in an uncomfortable position, such as on a rock or the cement, could also put undue pressure on the anal muscles, causing hemorrhoids.
