The most common age is normally between 45 to 65 years.
 Even though most people think hemorrhoids are abnormal, they're present in everyone.
It's only when the hemorrhoidal pillows enlarge that hemorrhoids can cause problems and be considered abnormal or a disease.
Hemorrhoids are a piled up masses or clumps of tissue coming from the unsmooth circulating of venous blood in the anus part on the human body.
 It's normally present veins in the anus and rectum that become swollen and inflamed.
Hemorrhoids can be divided into internal hemorrhoids, external hemorrhoids, mixed hemorrhoid and so on.
The veins in the anal canal can swell which forms internal hemorrhoids.
Also, near the opening of the anus if veins swell then form external hemorrhoids.
You also can have both types at the same time.
Hemorrhoids look like slight ailments but actually have great harm on human's body.
Venous Blood will come into being hemorrhoids because of long-term accumulation.
Greater or larger Hemorrhoids then occur and even prolapsed with the forming of external hemorrhoids and mixed hemorrhoids and perforation of hemorrhoids.
This could lead to, leaking waste matter discharge from the body, passage of bloody stools, redness of cloacal opening, excessive itching and other symptoms will arise.

Internal hemorrhoids are the ones that are inside the anal cavity.
 Normally it causes painless bleeding at the end of a bowel movement.
Other symptoms are a feeling of fullness, sometimes said as feeling the urge to have a bowel movement even when there is no stool.
Straining gets worse and the discomfort does also.
You might also feel sharp pain, itching, and irritation around the anus.
This usually happens when the hemorrhoid has prolapsed and you can see it outside the anus or it can be caused when a blood clot develops.
There may be a painful lump or swelling around the anus as well.

The causes of hemorrhoids are usually caused putting to much pressure on the veins in the pelvic and anal area.
Normally, tissues inside the anus fills with blood to help control bowel movements.
If you strain to move stool, the increased pressure causes the veins in this tissue to swell and stretch, this also can cause hemorrhoids.
Diarrhea or constipation may lead to straining and can increase pressure on veins in the anal canal.
Pregnant women can get hemorrhoids during there last 6 months of pregnancy, it's because of the increased pressure on the blood vessels in the pelvic area, and also straining to push the baby out during labor can make it worse.
