The Million Women March for Endometriosis is being held March 13, 2014 in Washington, DC. This fact sheet provides an overview of the disease and helps explain why raising awareness of this condition is important.
• Endometriosis affects an estimated 1 in 10 women during their reproductive years (ie, usually between the ages of 15 to 49), which translates to approximately 176 million women in the world.1,2
• Depression is 15% to 20% higher for the chronically ill than for the average person.3
• Various studies have reported that physical illness and uncontrollable physical pain are major factors in up to 70% of suicides.4
• The 2002 US Census Bureau reported that approximately 96% of people who live with an illness have an illness that is invisible. They note that these people may look perfectly healthy.
• Endometriosis is one of the top three causes of female infertility. While it is one of the most treatable, it remains the least treated.5
• Up to 30% to 50% of women with endometriosis may experience infertility.6
• Anglo-American studies have shown a delay from 3 to 11 years between the onset of pain symptoms and the final diagnosis of endometriosis.7
• The National Endometriosis Society claims that around 2 million women in the UK have undiagnosed endometriosis.
• Studies carried out in the USA, the UK, and Australia have demonstrated that the difficulty in timely diagnosis of endometriosis is universal. The delay in diagnosis was recorded as 9.28 years in the North American Endometriosis Association Survey (NAEAS) of 4000 members; this includes a delay in the patient seeking help from a physician for an average 4.67 years and a delay of 4.61 years in the physician making a diagnosis of endometriosis.
• The length of time from the onset of symptoms to the definite diagnosis is often an average of 6 to 10 years. This delay is even longer in young patients and in severe cases.8-11
• A range of problems may result from this delay in diagnosis, including deterioration of patient's quality of life, progression of the disease, the impact of absence of an explanation of pain, and the financial burden on the budget of medical services.12
• Studies show adolescents usually turn to their primary care physician for evaluation of dysmenorrhea (painful periods) and chronic pelvic pain.13
• Many arguments exist to organize the clinical care for women with advanced endometriosis in centers of excellence, but continuing education of primary care physicians also remains a priority.14
• In survey findings, 63% of general practitioners indicated they felt ill at ease in the diagnosis and follow-up of patients with endometriosis. One half could not cite three main symptoms of the disease out of dysmenorrhea, dyspareunia, chronic pelvic pain, and infertility. Only 38% of general practitioners indicated that they perform a clinical gynecological examination for suspected endometriosis, and 28% recommended MRI to confirm the diagnosis.15-17
• Pain before and during periods
• Pain during sex
• Painful urination during periods
• Painful bowel movements during periods
• Other gastrointestinal upsets such as diarrhea, constipation, nausea.
In addition, many women with endometriosis suffer from:
• Chemical sensitivities
• Frequent yeast infections
Endometriosis is an estrogen-dependent disorder that can result in substantial morbidity, including pelvic pain, multiple surgeries, and infertility. Affected women are at higher risk than the general female population for ovarian cancer, and they also may be at increased risk for breast and other cancers as well as autoimmune and atopic disorders.18 It is recommended that clinicians assess and follow up affected women for these and other associated disorders.
There will probably be a new repertoire of approaches for treatment of disease-associated pain and infertility and perhaps cure of this enigmatic disorder as researchers better understand the science behind the genetics, the possible roles of the environment and the immune system, intrinsic abnormalities in the endometrium of affected women, and secreted products of endometriotic lesions.18
