About Hemorrhoids
The term
hemorrhoids refers to a condition in which the veins around the
anus or lower rectum are swollen and
inflamed.
Hemorrhoids may result from straining to move stool.
Other contributing factors include pregnancy, aging, chronic
constipation or diarrhea, and anal intercourse. Hemorrhoids are
either inside the anus (internal) or under the skin around the
anus (external).
Symptoms
Many
anorectal problems, including fissures, fistulae, abscesses, or
irritation and itching (pruritus ani), have similar symptoms
and are incorrectly referred to as
hemorrhoids.
Hemorrhoids usually are not dangerous or life
threatening. In most cases, hemorrhoidal symptoms will go away
within a few days.
Although
many people have hemorrhoids, not all experience symptoms. The
most common symptom of internal hemorrhoids is bright red blood
covering the stool, on toilet paper, or in the toilet bowl.
However, an internal hemorrhoid may protrude through the anus
outside the body, becoming irritated and painful. This is known
as a protruding hemorrhoid.
Symptoms
of external hemorrhoids may include painful swelling or a hard
lump around the anus that results when a blood clot forms. This
condition is known as a thrombosed external
hemorrhoid.
In
addition, excessive straining, rubbing, or cleaning around the
anus may cause irritation with bleeding and/or itching, which
may produce a vicious cycle of symptoms. Draining mucus may
also cause itching.
Diagnosis
A thorough
evaluation and proper diagnosis by the doctor is important any
time bleeding from the rectum or blood in the stool occurs.
Bleeding may also be a symptom of other digestive diseases,
including colorectal cancer.
The doctor
will examine the anus and rectum to look for swollen blood
vessels that indicate hemorrhoids and will also perform a
digital rectal exam with a gloved, lubricated finger to feel
for abnormalities.
Treatment
Medical
treatment of hemorrhoids is aimed initially at relieving
symptoms. Measures to reduce symptoms include
- tub
baths several times a day in plain, warm water for about 10
minutes
- application of a hemorroidal cream or suppository
to the affected area for a limited time
Preventing
the recurrence of hemorrhoids will require relieving the
pressure and straining of constipation. Doctors will often
recommend increasing fiber and fluids in the diet. Eating the
right amount of fiber and drinking six to eight glasses of
fluid (not alcohol) result in softer, bulkier stools. A softer
stool makes emptying the bowels easier and lessens the pressure
on hemorrhoids caused by straining. Eliminating straining also
helps prevent the hemorrhoids from
protruding.
Good
sources of fiber are fruits, vegetables, and whole grains. In
addition, doctors may suggest a bulk stool softener or a fiber
supplement such as psyllium (Metamucil) or methylcellulose
(Citrucel).
Prevention
The best
way to prevent hemorrhoids is to keep stools soft so they pass
easily, thus decreasing pressure and straining, and to empty
bowels as soon as possible after the urge occurs. Exercise,
including walking, and increased fiber in the diet help reduce
constipation and straining by producing stools that are softer
and easier to pass.
