What is Endometriosis?
Endometriosis is a chronic condition where tissue similar to the lining of the uterus (endometrium) grows outside the uterus. This tissue can be found on the ovaries, fallopian tubes, the outer surface of the uterus, and other areas in the pelvic cavity. In rare cases, endometriosis may even occur in more distant parts of the body, such as the lungs.
During a normal menstrual cycle, the endometrial tissue inside the uterus thickens and breaks down, resulting in menstrual bleeding. However, when endometrial-like tissue grows outside the uterus, it also responds to hormonal changes but cannot exit the body. This leads to inflammation, scarring, and the formation of adhesions, which can cause the reproductive organs to stick together.
Endometriosis is classified into four stages based on the location, size, and depth of the endometrial implants:
- Stage I (minimal)
- Stage II (mild)
- Stage III (moderate)
- Stage IV (severe)
It is important to note that the stage of endometriosis does not always correlate with the severity of symptoms. Some women with advanced stages may experience little to no pain, while others with mild endometriosis may have severe symptoms.
Endometriosis is a relatively common condition, affecting an estimated 2-10% of women of reproductive age. It is more prevalent among women with infertility, with 25-50% of infertile women being diagnosed with endometriosis. The exact cause of endometriosis is unknown, but several theories exist, including retrograde menstruation, genetic factors, and immune system dysfunction.
Symptoms of Endometriosis
The most common symptom of endometriosis is pelvic pain, either during or outside of the normal menstrual period that is beyond normal cramping. Normal menstrual cramping should be tolerable and should not require someone to miss time from school, work or normal activities.
Other symptoms of endometriosis include:
- Cramps that begin before and extend after a menstrual period
- Lower back or abdominal pain
- Pain with intercourse
- Pain with bowel movements or urination
- Infertility
Individuals with endometriosis may also experience fatigue, constipation, bloating, or nausea, especially during periods. The symptoms of endometriosis can vary from person to person. Some people may have very few patches of endometriosis and still experience severe pain, while others might have severe endometriosis but not experience a great deal of pain.
It’s important to note that endometriosis symptoms are variable and broad, meaning that healthcare workers may not easily diagnose it. Individuals with symptoms may not be aware of the condition. If you are experiencing any of these symptoms, it’s a good idea to talk to your healthcare provider for proper diagnosis and treatment options.
Causes and Risk Factors
The exact cause of endometriosis is still uncertain, but there are several possible explanations for what sparks the endometrial-like tissue to grow outside the uterus. Some of the potential causes include:
- Blood or lymph system transport: Endometrial tissues may be transported to other areas of the body through the blood or lymphatic systems, similar to how cancer cells can spread.
- Direct transplantation: Endometrial cells may attach to the walls of the abdomen or other areas of the body after surgery, such as a C-section or hysterectomy.
- Genetics: Endometriosis seems to affect some families more often than others, suggesting a potential genetic link to the condition.
- Reverse menstruation: Endometrial tissue may go into the fallopian tubes and the abdomen instead of exiting the body during a woman’s period.
- Transformation: Other cells in the body may transform into endometrial cells and start growing outside the endometrium.
While the exact cause remains unknown, certain factors can increase the risk of developing endometriosis:
- Never giving birth
- Menstrual cycles occurring more frequently than every 28 days
- Heavy and prolonged menstrual periods lasting longer than seven days
- Having higher levels of estrogen in the body
- Having a low body mass index
- Structural issues with the vagina, cervix, or uterus that prevent the passage of menstrual blood from the body
- Family history of endometriosis
- Starting menstruation at an early age
- Starting menopause at an older age
Additionally, the more exposure a person has to menstruation, the higher the chance of developing endometriosis. Factors that increase menstrual exposure and thus the risk include:
- Having 27 days or fewer between each period
- Starting the first period before the age of 12 years
- Experiencing periods that last seven days or longer each month
Pregnancy, which reduces the number of times a person has periods, decreases the risk of endometriosis. If someone with endometriosis becomes pregnant, their symptoms may fade during the pregnancy but commonly return after the baby is born.
Diagnosis of Endometriosis
Diagnosing endometriosis can be challenging, as the symptoms often mimic other conditions. To determine if a person has endometriosis, healthcare providers typically begin with a physical exam and a discussion of the individual’s symptoms, including the location and timing of pain.
Several tests can be performed to check for signs of endometriosis:
- Pelvic exam: During a pelvic exam, the healthcare provider uses one or two gloved fingers to feel for any abnormalities in the pelvic area, such as cysts on the reproductive organs, painful spots, nodules, or scars behind the uterus. However, small areas of endometriosis may not be detectable unless a cyst has formed.
- Ultrasound: An ultrasound uses sound waves to create images of the internal organs. The transducer may be pressed against the abdomen or inserted into the vagina (transvaginal ultrasound). While a standard ultrasound cannot definitively diagnose endometriosis, it can identify cysts associated with the condition, known as endometriomas.
- Magnetic Resonance Imaging (MRI): An MRI uses a magnetic field and radio waves to produce detailed images of the organs and tissues within the body. This test can help with surgical planning by providing the surgeon with information about the location and size of endometriosis growths.
- Laparoscopy: Laparoscopy is the only way to confirm an endometriosis diagnosis definitively. During this minimally invasive surgical procedure, the surgeon makes a small incision near the navel and inserts a thin viewing instrument called a laparoscope to examine the abdominal cavity for endometriosis tissue. The surgeon may also take a biopsy for further testing. If endometriosis is found, the surgeon can often treat it during the same procedure.
It is important to note that a healthcare provider will only perform a laparoscopy after obtaining a full medical history and conducting a thorough physical and pelvic exam. The information gathered from these assessments, along with the results of an ultrasound or MRI, will help the individual and their healthcare provider make informed decisions about treatment options.
Researchers are also working on developing less invasive methods to diagnose endometriosis and determine its severity. For example, NICHD-funded researchers have created a “diagnostic classifier” for endometriosis based on the presence of specific genes, with an accuracy of 90% to 100%. Once validated, this classifier may allow for a nonsurgical diagnosis of endometriosis through a simple biopsy in a doctor’s office.
Complications of Endometriosis
Endometriosis can lead to several complications that may significantly impact a woman’s quality of life. Some of the most common complications associated with endometriosis include:
Fertility Problems
Endometriosis can cause fertility issues, making it difficult for affected women to conceive. The exact mechanism is not fully understood, but it is thought to be related to damage to the fallopian tubes or ovaries. However, not all women with endometriosis will experience infertility, and some may be able to get pregnant without treatment. Medications alone will not improve fertility, but surgery to remove endometriotic tissue can sometimes help. If infertility persists, assisted reproductive techniques such as in vitro fertilization (IVF) may be an option, although success rates tend to be lower in women with moderate to severe endometriosis.
Adhesions and Ovarian Cysts
Women with endometriosis may develop adhesions, which are “sticky” areas of endometriotic tissue that can bind organs together. Additionally, they may develop ovarian cysts called endometriomas, which can become large and painful. These complications often occur when the endometriotic tissue is located on or near the ovaries. While surgery can treat adhesions and ovarian cysts, there is a risk of recurrence if the endometriosis returns.
Surgery Complications
Like any surgical procedure, surgery for endometriosis carries certain risks. Common complications, which are usually not serious, include:
- Wound infections
- Minor bleeding
- Bruising around the incision site
More serious but less common risks include:
- Damage to organs, such as accidental punctures to the uterus, bladder, or bowel
- Severe internal bleeding
- Blood clots in the legs (deep vein thrombosis) or lungs (pulmonary embolism)
It is essential for patients to discuss the potential benefits and risks of surgery with their surgeon before undergoing the procedure.
Bladder and Bowel Problems
Endometriosis affecting the bladder or bowel can be particularly challenging to treat and may require extensive surgery. In such cases, referral to a specialized endometriosis center may be necessary. Surgery for bladder endometriosis may involve partial removal of the bladder, and a urinary catheter may be temporarily required post-operatively. In rare cases, a urostomy, where urine is collected in a bag attached to a small opening in the abdomen, may be needed. Similarly, treatment for bowel endometriosis may require the removal of a portion of the bowel, and a temporary colostomy may be necessary to allow the bowel to heal.
Treatment Options for Endometriosis
There are several treatment options available for managing endometriosis symptoms and improving quality of life. The choice of treatment depends on factors such as the severity of symptoms, the extent of the disease, and whether the woman wishes to become pregnant.
Pain Medications
Over-the-counter pain relievers like nonsteroidal anti-inflammatory drugs (NSAIDs), including ibuprofen and naproxen sodium, can help alleviate painful menstrual cramps associated with endometriosis. However, the effectiveness of these medications in treating endometriosis-related pain is limited.
Hormone Therapy
Hormone therapy aims to slow the growth of endometrial tissue and prevent new lesions from forming. Several types of hormone treatments are used to manage endometriosis:
- Hormonal contraceptives: Birth control pills, patches, and vaginal rings containing estrogen and progestin can help control the hormones that stimulate endometriosis growth. Continuous use of these contraceptives may provide better pain relief.
- Antagonists: These medications block the production of hormones responsible for ovulation, menstruation, and endometriosis growth. They induce a temporary menopausal state and can cause side effects like hot flashes, vaginal dryness, and bone loss.
- Progestin therapy: Progestins, such as levonorgestrel (delivered through an intrauterine device), contraceptive implants, or birth control shots, can stop menstrual periods and endometriosis tissue growth.
- Aromatase inhibitors: These medications lower estrogen levels in the body and may be used in combination with other hormonal treatments.
It is important to note that while hormone therapy can effectively manage endometriosis symptoms, it is not a permanent solution, and symptoms may return once the treatment is stopped.
Conservative Surgery
Conservative surgical procedures aim to remove endometriosis tissue while preserving the uterus and ovaries. Laparoscopy, a minimally invasive surgery, is commonly used to diagnose and treat endometriosis. During the procedure, the surgeon makes small incisions in the abdomen, inserts a laparoscope to visualize the lesions, and removes or destroys the endometriosis tissue using surgical instruments or laser.
Laparoscopic surgery can provide significant pain relief, especially in cases of severe endometriosis. However, there is a risk of endometriosis recurrence after surgery, and pain may return over time.
Hysterectomy with Removal of the Ovaries
In severe cases of endometriosis that do not respond to other treatments, a hysterectomy (surgical removal of the uterus) along with the removal of the ovaries may be considered as a last resort. This procedure induces early menopause and can lead to a significant reduction in endometriosis pain. However, it is not always a guaranteed solution, as endometriosis tissue may still be present and cause symptoms even after the surgery.
Fertility Treatment
For women with endometriosis who wish to become pregnant, fertility treatments may be recommended. Laparoscopic surgery to remove endometrial lesions can improve fertility in some cases. If pregnancy does not occur naturally after surgery, assisted reproductive technologies like in vitro fertilization (IVF) may be considered.
Alternative and Complementary Therapies
Some women with endometriosis find relief from alternative therapies such as acupuncture, chiropractic care, herbal remedies, and dietary supplements. However, there is limited scientific evidence supporting the effectiveness of these treatments for endometriosis. It is essential to consult with a healthcare provider before trying any alternative therapies to ensure their safety and potential interactions with other medications.
Ultimately, the best approach to treating endometriosis is a personalized one that takes into account the individual’s specific symptoms, goals, and overall health. Working closely with a healthcare provider who specializes in endometriosis can help women navigate the various treatment options and find the most effective management plan for their unique situation.
