Swollen Hemroids 

Hemroids are abnormally swollen veins in the rectum and anus. They are much like varicose veins you might see on a person's legs. When bulging hemroidsal veins are irritated, they cause surrounding membranes to swell, burn, itch, become very painful, and bleed. Hemroids are caused by too much pressure in the rectum, forcing blood to stretch and bulge the walls of the veins, sometimes rupturing them. Listed below are the most frequent causes of hemroids: 

• Constant sitting 

• Straining with bowel movements (from constipation or hard stools) 

• Diarrhea 

• Sitting on the toilet for a long time 

• Severe coughing 

• Childbirth 

• Heavy Lifting 

There are two kinds of hemroids: internal and external 
Internal hemroids usually don't hurt or itch; you can't feel them because they are deep inside the rectum. Internal hemroids are pretty harmless. But since their bleeding could mask blood from a dangerous source like colorectal cancer, they should be treated. 

External hemroids cause most of the symptoms we commonly hear about - pain, burning, and itching. If an external hemroids becomes strangulated (cut off from blood supply), a clot can form in it and become an excruciatingly painful thrombosed hemroids. Because of these unpleasant symptoms, external hemroids get the most treatment attention. 

Once the rectal veins have been stretched out and hemroids created, they are difficult to get rid of completely and tend to recur with less straining than it took to cause them in the first place. Fortunately, good habits and simple medical treatment usually control hemroids well, and surgery is only recommended in unusually severe cases.
