Enlarged veins that occur in the anal canal are known as hemorrhoids. While hemorrhoids are uncomfortable they are rarely a serious health problem until they become severe hemorrhoids. To help control bowel movements the tissue surrounding the anus known as the anal cushions will fill with blood. When the veins in these cushions swell and stretch they will lead to hemorrhoids. At some point in their life everyone will have hemorrhoids. Any age can experience hemorrhoids although those after the age of thirty have an increased risk.

Hemorrhoids are caused by excessive pressure on the pelvic and rectal veins. Blood pools in the veins as the pressure increases which causes swelling and stretching in the surrounding tissues which leads to hemorrhoids. Rushing to complete a bowel movement, persistent diarrhea or constipation can also lead too hemorrhoids if there is too much straining.

Developing hemorrhoids can also be linked to being overweight. During the last six months of pregnancy women may frequently develop hemorrhoids because of the increased pressure on the pelvic blood vessels. Hemorrhoids can also be caused by the strain of pushing the baby out during birth.

Types of Hemorrhoids

There are two main types of hemorrhoids, internal and external. Both of these can occur at the same time. Depending on where the hemorrhoids develop the symptoms, progression and treatment will vary. There are four degrees of severe hemorrhoids when it comes to the internal type. Any of these severe hemorrhoids may experience bleeding. First degree severe hemorrhoids do not protrude from the anus and remain largely internal.

During a bowl movement, second degree severe hemorrhoids will protrude from the anus and then return to the anal canal after. Third degree severe hemorrhoids must be pushed back into the anus with your finger after a bowel movement. Then the fourth degree severe hemorrhoids are always outside of the anus and cannot be pushed back inside the canal.

Symptoms of Severe Hemorrhoids

With external severe hemorrhoids there are symptoms such as itching, burning and irritation. After straining to have a bowel movement you may find streaks of bright red blood on the toilet paper and the anal area may be difficult to clean.

For internal severe hemorrhoids the most common symptom is bleeding. There may be blood in the toilet bowl after a bowel movement and some blood may be on the surface of the stool. Severe internal hemorrhoids may have pain if they are protruding all the time. Severe hemorrhoids that protrude may have mucus on the stool or toilet tissue after a bowel movement.
