Many women can have endometriosis but have no endometriosis symptoms. No two women will have the same symptoms
of endometriosis and some may experience no signs of endometriosis at all. Some women experience pain that
gradually worsens while others find pain varies each month. Often endometriosis pain is thought to be from normal
menstruation but as the pain worsens over time a woman realizes there is a problem.
The level of pain a woman experiences is not related to the amount of endometriosis growth in her body. A woman
can have very little or no pain but still have extensive development of endometriosis. Likewise, a woman can have
severe endometriosis pain but only a small amount of endometriosis.
Pelvic pain is by far the most common sign of endometriosis. Infertility is another common symptom, affecting
about 1 in 3 women with endometriosis. The type and severity of pelvic pain depends upon the location of the
What is Endometriosis?
Endometriosis is the presence and growth of endometrial cells outside the uterus. The disease begins
when normal endometrial cells from the inside of the uterus are released and adhere to the outside of the
uterus, ovaries or other organs in the pelvic area. This abnormal growth is not cancerous but can cause other
An endometrioma is a kind of cyst that is caused by endometriosis. An endometrioma, also called an endometrioma
cyst, or “chocolate cyst” is a sac filled with fluid and or solid blood mass that develops inside the ovaries.
These cysts originate from small sections of endometrial tissue shed by the uterine wall.
Endometriosis Symptoms and other Diseases
It is very common for endometriosis symptoms to be mistaken for other health problems. This is because some
symptoms of endometriosis are present in other diseases such as:
• Ovarian cysts
• Pelvic inflammatory disease
• Ectopic pregnancy
• Irritable bowel syndrome
• ovarian cancer
• uterine fibroids
• fibroid tumours
• colon cancer
In addition to pelvic pain, the most common symptoms of endometriosis
• Irregular and/or heavy periods
• Bleeding between periods or discharge of blood clots
• Pain before and during periods but less after periods
• Pain during sexual intercourse especially when blood is present
• Constant dull pain in the pelvic area
• Lower back pain
• Pain in the abdomen especially cramping or sharp pain
• Pain in the bowels or rectum
• constipation or diarrhea especially with blood present
• Pain while urinating especially with blood
• Lack of energy or fatigue
Other common endometriosis symptoms:
There are thought to be endometriosis stages through which the disease progresses. As endometriosis
develops into later stages, a woman’s immune system can become weakened. She is then more likely to suffer
infections and other diseases including chronic fatigue syndrome (CFS), fibromyalgia, Rheumatoid arthritis, and
• Migraine headaches
• Bloating or feeling of fullness in the lower abdomen
• Fevers and or vomiting
• Low blood sugar (hypoglycemia)
• Panic attacks
• Frequent infections or signs of allergies
Endometriosis Symptoms by Location in the Body
Endometriosis can grow in different parts of the body tissues, including the ovaries, uterus, fallopian tubes,
cervix, space between the vagina and rectum, the inner layer of the pelvic cavity, large and small intestines,
bladder and bowels. Though not common, endometriosis can develop in other parts of the body including the surface
of the liver, lungs and brain.
Endometrial cancer symptoms
Endometriosis and endometrial cancer are similar in that both are abnormal growth of the endometrial tissue of
the uterus. Endometrial cancer symptoms can be similar to endometriosis symptoms. The important difference between
the two though is that endometrial cancer growths can be fatal while endometriosis is benign. It is unknown to what
degree endometriosis is connected to endometrial cancer risk. There may exist a link to other forms of cancer
however, such as ovarian cancer and brain cancer.
Endiometriosis symptoms and uterine cancer symptoms
Endometriosis symptoms can be very similar to uterine cancer symptoms and ovarian
cancer symptoms. It’s no surprise then that nearly all uterine cancer cases involve endometrial cancer.
Menopausal women are most likely to have uterine cancer and should be aware of the following symptoms: pelvic pain,
pain during urination or sexual intercourse, and bleeding separate from normal menstrual.
