WHAT IS A HEMORRHOID?
Hemorrhoids consist of both arteries and veins in the rectum which can become engorged or inflamed due to
an increase in venous pressure.
WHAT CAUSES HEMORRHOIDS?
Hemorrhoids are caused by increased pressure in the hemorrhoid system of vessels. These vessels can
become dilated when exposed to chronic or intermittent pressure. Hemorrhoids may become symptomatic as
a result of activities that cause an increase in venous pressure. Pregnancy, constipation, prolonged sitting,
obesity, low-fiber diet, physical exertion and straining during bowel movements all may contribute to the
exacerbation of hemorrhoids.
WHAT ARE THE SYMPTOMS OF INTERNAL HEMORRHOIDS?
The most common symptoms of internal hemorrhoids are painless bleeding and protruding bulge. There are
many types of anorectal pathology that can cause rectal bleeding. It is imperative to notify your physician
immediately if you have this symptom so the cause can be determined. Symptomatic hemorrhoids are often
associated with discharge, rectal itching, tissue prolapse and aching after a bowel movement.
WHAT ARE THE SYMPTOMS OF EXTERNAL HEMORRHOIDS?
External hemorrhoids develop near the anus and are covered by very sensitive skin. These are usually
painless. However, if a blood clot (thrombosis) develops in an external hemorrhoid, it becomes a painful hard
lump. The external hemorrhoid may bleed if it ruptures.
