Hemorrhoids
What are hemorrhoids?
Hemorrhoids are found inside the anus and/or under the skin around the
anus. Straining to move stool may cause
Hemorrhoids. Hemorrhoids occur when the veins around the anus
or lower rectum are swollen and inflamed.
Straining or irritation from passing stool can injure a hemorrhoid's
delicate surface and cause it to bleed. Due to internal anal membranes
lacking pain-sensitive nerve fibers, the internal hemorrhoids typically
do not cause discomfort but you might experience a feeling of fullness
in your rectum following a bowel movement. Sometimes straining pushes
internal hemorrhoids through the anal opening. If a hemorrhoid remains
displaced it can cause pain and irritation. Blood may pool in
an external hemorrhoid and form a clot causing severe pain, swelling
and inflammation.
You can't see or feel internal hemorrhoids. External
hemorrhoids are usually painful.
Pregnancy, aging, chronic constipation or diarrhea and anal intercourse
may cause Hemorrhoids.
What are signs that you have hemorrhoids?
In most instances, Hemorrhoids are not dangerous. In fact, most
symptoms of hemorrhoids are gone within a few days. Some
anorectal conditions have similar symptoms and are incorrectly referred
to as hemorrhoids. These other anorectal conditions include
fissures, fistulae, abscesses, or irritation and itching.
A protruding hemorrhoid is an internal hemorrhoid that protrudes
through the anus outside the body and becomes both irritated and
painful. Some people have hemorrhoids even though they do not
experience any symptoms of hemorrhoids. The most common symptom of
internal hemorrhoids is bright red blood covering the stool, on toilet
paper, or in the toilet bowl.
External hemorrhoids may have the following symptoms: painful swelling
or a hard lump around the anus which is the result of a blood clot
forming. This external hemorrhoid condition is called thrombosed
external hemorrhoid.
Excessive straining, rubbing, or cleaning around the anus may cause
irritation with itching and/or bleeding. Itching may also be caused by
draining mucus.
When irritated, external hemorrhoids can itch or bleed.
Are hemorrhoids very common?
Men and women both may have hemorrhoids, this is a common condition in
both men and women. By age 50 half of the population has hemorrhoids.
Hemorrhoids are also common among pregnant women because the fetus puts
pressure on the abdomen. Hormonal changes in pregnant women
may also cause hemorrhoidal vessels to enlarge. These hemorrhoidal
vessels are placed under intense pressure during childbirth.
Hemorrhoids caused by pregnancy are a temporary problem with most women.
What is the method used to diagnose hemorrhoids?
The doctor will examine the anus and rectum to look for swollen blood
vessels which indicate that hemorrhoids are present. The doctor will
also perform a digital rectal exam with a gloved, lubricated finger in
order to check for abnormalities. If bleeding from the rectum
or blood in the stool occurs, an evaluation and diagnosis by a doctor
is very important . Bleeding from the rectum or blood in the stool may
also be a symptom of digestive diseases such as colorectal cancer.
An exam with an anoscope, which is a hollow, lighted tube useful for
viewing internal hemorrhoids, or a proctoscope, which is useful for
examining the entire rectum, will be used by the doctor in order to
take a closer examination of the rectum for hemorrhoids.
The doctor may examine the rectum and lower colon with sigmoidoscopy or
the doctor may examine the entire colon with colonoscopy in order to
rule out other causes of gastrointestinal bleeding. Sigmoidoscopy and
colonoscopy are procedures involving the doctor using a lighted,
flexible tubes inserted through the rectum in order to view the rectum
and lower colon.
How may I medically treat hemorrhoids?
Initially, the goal is to relieve symptoms. A 10-minute warm water tub
bath several times a day and use of a hemorrhoidal cream or suppository
may be used to relieve symptoms. It is a good idea to
re-increase fiber and fluid intake which will result in a softer,
bulkier stool.
In order to prevent hemorrhoids from recurring, doctors recommend
relieving the pressure and straining of constipation. In turn, a softer
stool will make emptying the bowels easier and less straining will
lesson hemorrhoid pressure and help to prevent hemorrhoids from
protruding.
Fruits, vegetables and whole grains are a great source of fiber. It may
also be suggested by your doctor that you use a bulk stool softener or
a fiber supplement such as Metamucil or Citrucel.
Hemorrhoids sometimes need to be removed through surgery.
Below is a list of techniques used to remove or reduce the size of
internal hemorrhoids:
Rubber band ligation. The doctor will
place a rubber band around the base of the hemorrhoid. The band will
cut off circulation to the hemorrhoid causing it to wither away soon
after.
Sclerotherapy. In order to shrink the
hemorrhoid, a chemical solution is injected around the blood vessel.
Infrared coagulation. A device burns
the hemorrhoidal tissue.
Hemorrhoidectomy. Severe hemorrhoids
may be removed through surgery.
What can I do to prevent hemorrhoids?
Diet (increasing your fiber intake) and exercise are the best ways to
prevent hemorrhoids. A soft stool will decrease pressure and
straining.
