Endometriosis : Causes and Symptoms
Endometriosis
is the abnormal growth of endometrial tissue similar to that which lines the
interior of the uterus, but in a location outside of the uterus. Endometrial
tissue is shed each month during menstruation. Areas of endometrial tissue
found in ectopic locations are called endometrial implants. These lesions are
most commonly found on the ovaries, the Fallopian tubes, the surface of the
uterus, the bowel, and on the membrane lining of the pelvic cavity. They are
less commonly found to involve the vagina, cervix, and bladder. Rarely,
endometriosis can occur outside the pelvis. Endometriosis has been found in
the liver, brain, lung, and old surgical scars. Endometrial implants,
while they may become problematic, are usually benign.
Symptoms
Other
medical conditions such as pelvic inflammatory disease, ovarian cysts,
and irritable bowel syndrome can mimic the symptoms of
endometriosis.Symptoms of endometriosis include:
●Severe menstrual cramps, unrelieved
with NSAIDS
●Long-term lower-back and pelvic
pain
●Periods lasting longer than 7 days
●Heavy menstrual bleeding where the
pad or tampon needs changing every 1 to 2 hours
●Bowel and urinary problems
including pain, diarrhea, constipation, and bloating
●Bloody stool or urine
●Fatigue
●Pain during intercourse
Pain is the
most common indication of endometriosis, but the severity of the pain does not
always correlate with the extent of the disease.Pain often resolves after menopause,
when the body stops producing estrogen production. However, if hormone therapy
is used during menopause, symptoms may persist.Pregnancy may provide temporary
relief from symptoms.
Causes
Although
the exact cause of endometriosis is not certain, possible explanations include:
●Retrograde menstruation. In retrograde menstruation,
menstrual blood containing endometrial cells flows back through the fallopian
tubes and into the pelvic cavity instead of out of the body. These displaced
endometrial cells stick to the pelvic walls and surfaces of pelvic organs,
where they grow and continue to thicken and bleed over the course of each
menstrual cycle.
●Transformation of peritoneal cells. In
what's known as the "induction theory," experts propose that hormones
or immune factors promote transformation of peritoneal cells — cells that line
the inner side of your abdomen — into endometrial cells.
●Embryonic cell transformation. Hormones such as estrogen
may transform embryonic cells — cells in the earliest stages of development —
into endometrial cell implants during puberty.
Treatment
Treatment
for endometriosis is usually with medications or surgery. The approach you and
your doctor choose depends on the severity of your signs and symptoms and
whether you hope to become pregnant. Generally, doctors recommend trying
conservative treatment approaches first, choosing surgery as a last option.
Diagnosis
Endometriosis
is most commonly treated by obstetrician-gynecologists. Endometriosis can be
suspected based on symptoms of pelvic pain and findings during physical
examinations. Occasionally, during a rectovaginal exam (one finger in the
vagina and one finger in the rectum), the doctor can feel nodules (endometrial
implants) behind the uterus and along the ligaments that attach to the pelvic
wall. At other times, no nodules are felt, but the examination itself causes
unusual pain or discomfort. Unfortunately, neither the symptoms nor the
physical examinations can be relied upon to conclusively establish the
diagnosis of endometriosis
Exercise,
such as walking, may reduce pain and slow the progress of the condition by
reducing estrogen levels. It is important to spot symptoms on time, because of
the long-term complications of endometriosis. Intolerable pain or unexpected
bleeding should be immediately reported to a doctor. Although there is
currently no cure for endometriosis, most women are able to relieve the pain and will still be able to have children.
