Summary

Endometriosis is a complex condition that can be challenging to diagnose, often remaining undetected until severe symptoms arise or infertility issues occur. The primary symptom is pelvic pain, particularly during menstrual cycles, but the severity of pain does not correlate with the extent of the disease. Other common symptoms include gastrointestinal disturbances, painful intercourse, painful bowel movements, neuropathy, and infertility.

Recognizing the various symptoms is crucial for timely diagnosis and treatment. Women experiencing symptoms such as dysmenorrhea, chronic pelvic pain, or gastrointestinal issues should consult a healthcare provider for evaluation and potential management options.

It can be very difficult for any woman, regardless of her age, to recognize the symptoms of endometriosis. The disease often goes undiagnosed for years, only to be discovered when a patient experiences infertility or symptoms that have become very severe. The most common symptom of endometriosis is pain in the lower abdomen, the pelvis, or the lower back, predominantly during menstrual cycles. However, the amount of pain a woman feels does not depend on how much endometriosis she may have. Some women experience no pain, even though their disease affects large areas. Others experience severe pain, despite having only a few small endometriosis growths.

The six cardinal symptoms of endometriosis

1. Dysmenorrhea (painful periods)

Cramping during periods usually points to a uterine source, while pain and aches point to the peritoneum and ligaments. Endometriosis pain does not disappear in one day. The duration of pain associated with endometriosis usually continues for over two days. But it can even persist after your period is over. Pain from endometriosis characteristically does not respond well to painkillers and birth control pills. Over three out of four women with endometriosis have a history of incredibly painful, crampy periods since their adolescence. Ovulation (that occurs on or around day 14 of the reproductive cycle) is often also very painful in patients with endometriosis. Once a patient goes through menopause, they may still experience non-menstrual pelvic pain.

Since pain is a subjective experience, its description varies from one individual to another. Association with other symptoms, like frequent or painful bowel movements, gas around and during periods, constipation, and diarrhea, is common in cases of endometriosis. Therefore, the nature and duration of painful periods and their association with other symptoms are important in making clinical decisions and ruling out other pelvic disorders.

2. GI abnormalities

Another cardinal symptom of endometriosis is the gastrointestinal (GI) triad of bloatedness, gassiness, and cramps associated with or without diarrhea and constipation. Generally, these are more pronounced around menstruation.

3. Dyspareunia (painful sex) and painful orgasm

Painful sex (dyspareunia) and painful bowel movements
Painful sex (dyspareunia) and painful bowel movements are two of the cardinal symptoms of endometriosis. In this image, there is deep involvement of endometriosis in the posterior cul-de-sac (the area between the back of the uterus and rectum). During sexual intercourse or a bowel movement, this area of tissue becomes irritated and causes pain due to the build-up of endometriosis scar tissue.

Painful sex, the fourth cardinal symptom, is at times positional and usually involves deep involvement of endometriosis in the rectovaginal septum and pelvic walls. This symptom often leads to intimacy issues, as intercourse starts to become unpleasant for a woman. If your partner suffers from endometriosis and is experiencing dyspareunia, it is important to be kind, supportive, and mindful of the endometriosis pain they may be experiencing.

4. Painful bowel movements

Painful bowel movement may point to endometriosis in the rectovaginal septum and pelvic lateral walls. Endometriosis patients are often misdiagnosed as having IBS when their symptoms are caused by endometriosis.

5. Neuropathy

The nerves may be directly involved or stimulated by surrounding pathology due to the swelling and scarring that changes the retroperitoneum (the space in the abdomen behind the peritoneum), as well as the direct involvement of the nerves. Symptoms naturally differ—from changes in sensation to pain radiating to the back, lumbosacral area, inner thigh, or along the course of the sciatic nerve—according to the location of the endometriosis lesions. Some of these patients find they cannot comfortably cross their legs; in some cases, the disease affects their gait.

The peripheral nervous system in the uterus and ovaries directly feeds into the central nervous system: the body’s brain and spinal cord. In cases of endometriosis, these nerve signals can be damaged, resulting in nerve pain that radiates to the leg, back, and inner thigh.

6. Infertility

The most frequent yet most elusive symptom of endometriosis is infertility, which is both the difficulty in conceiving and the difficulty in carrying a pregnancy to term. Due to its silent nature, we sometimes call infertility the “cardinal symptom 0” of endometriosis. Complex immunobiological factors at both the cellular and antibody levels contribute. Inflammatory toxins that arise because of endometrioma scar tissue do not allow the sperm and egg to join naturally. Endometriosis causes visible tubal dysmorphisms and ovarian pathology in the form of micro-endometriomas and adhesions that serve as barriers to a successful pregnancy. Unable to get pregnant, many patients are unnecessarily treated with in-vitro fertilization treatments without their endometriosis ever being addressed.

What to do if you have symptoms of endometriosis?

An endometriosis diagnosis is dependent on a physician’s evaluation, in which the patient’s medical history will be discussed, and a pelvic exam will be conducted. The presence of the disease can only be confirmed by subsequent laparoscopy and pathology. However, you know your body best. If you feel that you have the aforementioned symptoms and that endometriosis may be the probable cause, you do not need to suffer. Consult with Seckin Endometriosis Center today.
