Hemorrhoids occur when excessive strain is placed on the veins in the anus and rectum. This might be because of weakening over time, or it might happen because of chronic diarrhea or constipation. Hemorrhoids come in several forms and levels of severity, and it is largely dependent on these how bad the symptoms will be.
In their beginning stage, internal hemorrhoids are perhaps the least severe of the types. While there may be some itching and discomfort, for the most part, you may not even realize they are there. However, the presence of bright red blood on the toilet paper or in the toilet, particularly after a difficult bowel movement, can be an indicator.
