Endometriosis isn’t the uterine lining – it’s tissue that’s SIMILAR to it.
Endometriosis does NOT bleed and shed with your period and then that blood has no where to go. Endo does NOT act like the uterine lining (endometrium) because it’s NOT the uterine lining.
Endometriosis isn’t caused by retrograde menstruation.
Hysterectomy, pregnancy, and medical (or natural) menopause don’t treat endometriosis.
Birth controls, hormones, and GnRh drugs (such as Lupron, Orilissa, Zoladex, Visanne, Dienogest, Mirena IUD) don’t treat or diagnose endometriosis. These treat the SYMPTOMS ONLY. They don’t stop the progression of endometriosis nor remove the existing lesions.
Endometriosis doesn’t just affect reproductive organs – it can be found in other body locations as well, such as the intestines, bladder, lung, or diaphragm.
Teens and postmenopausal womxn can have endometriosis. There is no age too old or too young. Endometriosis has been found in fetuses as well as people in their 70s!
You can have a negative ultrasound or MRI and STILL have endometriosis, as not all forms of endometriosis show up on scans. Additionally, when endometriosis signs are present on a scan, not all doctors have experience in recognizing them.
The only way to have a confirmed diagnosis of endometriosis is via surgery and a pathology report.
There are 2 types of surgery: ablation (superficial burning of endometriosis) and excision (cutting out at the root.) With excision, the rate of recurrence (endo coming back) can be as low as 7%. With ablation, disease persistence is fully expected, since the endometriosis wasn’t truly removed in the first place (and therefore persists).
Most gynecologists do ablation surgery. It takes special training and high levels of skill to do excision, so there are only about 200 excision specialists worldwide. See the treatment section below for more information and links for finding a doctor.
You aren’t doomed. Even without excision, many people live with less or no symptoms by changing their diet and lifestyle, reducing stress, or doing Traditional Chinese Medicine (such as acupuncture or Chinese herbs).

What is Endometriosis?
Endometriosis is tissue similar to the endometrium (the uterine lining) but is NOT the endometrium, despite what many misinformed websites and even doctors say! These endometriosis lesions shouldn’t be in the body. While endo is most commonly found on the female reproductive system, it has been found in nine other body systems. Patients with endometriosis may have it on the ovaries, peritoneum (lining of the abdomen cavity and organs), bowel, bladder, uterosacral ligaments, rectovaginal septum, lung, diaphragm, or other parts of the body.
There are three types of endometriosis: Superficial (lesions are less than 5mm deep), Ovarian Endometrioma (a cyst caused by endo on the ovary; also knows as chocolate cysts), and Deeply Infiltrating Endometriosis (when lesions are more than 5mm deep). DIE is considered the most severe form of endometriosis.
Endometriosis has glands and stroma, but doesn’t generally have blood vessels. Endometriosis glands secrete an inflammatory substance, which can irritate the surrounding tissue and destabilize nearby capillaries, causing bleeding in the surrounding tissues. This bleeding and inflammation can cause an immune response, the formation of scar tissue and adhesions, new blood vessels to grow in surrounding tissue (angiogenesis), and pain.
Endometriosis is often staged using the American Society for Reproductive Medicine Classification System (ASRM). This categorizes endometriosis into 4 stages. Stage I is minimal endometriosis, Stage IV is the most severe. However, this staging system was designed with fertility in mind. It doesn’t correlate to the level of pain a person has, so someone with Stage I could have more pain than someone in Stage IV. Also, when staging, it doesn’t take into account endo in locations such as the bladder, bowels, vagina, cervix, and more locations. The ASRM system has been criticized for having too much focus on the ovaries and adhesions.

Delay in Diagnosis
It’s estimated that more than 200 million womxn have endometriosis worldwide. It affects people of all races, nationalities, and gender identities who are biologically female. About one in ten people assigned female at birth have this disease. In spite of its prevalence, there is often a long delay in diagnosis. Various studies have shown that the average time to be diagnosed is between 4-11 years.
Delays in diagnosis can result for many reasons. The first hurdle many endometriosis patients encounter is just trying to get a doctor to take them seriously when they report their pain. It may be due to the sex and gender bias for womxn in medicine, a racial bias, or from the doctor’s lack of knowledge on endometriosis, but many patients report having their pain dismissed over and over again; being told that it’s “all in their head”, stress, or anxiety; or being told that “pain for womxn is normal.”
Once that hurdle to be taken seriously is crossed, gynecologists may believe the patient and suspect endometriosis but, due to a lack of training in the disease, are unable to diagnose it. They may not recognize the suggestion of its presence on scans such as ultrasounds or MRIs, or know that not all types of endometriosis show up on these scans, and therefore a negative scan doesn’t necessarily mean the patient doesn’t have endometriosis. Laparoscopy with a pathology report is the only way to have a definitive diagnosis of endometriosis, but many gynecologists who are not skilled in recognizing the various appearances or locations of endometriosis may miss obvious signs of the disease during surgery an exploratory surgery.
Another delay may result from receiving a misdiagnosis. Endometriosis symptoms can present as digestive complaints, urological symptoms, full body pain, joint pain, or other symptoms, depending on where it is located. This may prompt a patient to see a gastrointestinal doctor, urologist, rheumatologist, or another specialist who misdiagnoses them with a different condition when the underlying cause is actually endometriosis. With a misdiagnosis or even a co-condition, such as Painful Bladder Syndrome, Irritable Bowel Syndrome, or Fibromyalgia, endometriosis symptoms can be blamed on this other condition.

Hormonal therapy, such as GnRh drugs (Lupron, Orlissa, Zoladex, Synarel, Prostap, etc) that medically induce menopause, birth control (the pill, Visanne, Dienogest, Depo Provera, etc) or the Mirena IUD, only treats the symptoms of endometriosis, and doesn’t stop the progression of endometriosis nor remove the lesions. Neither a hysterectomy nor pregnancy cures endometriosis. However, due to misinformation, many gynecologists who are not experts in endometriosis use these various methods as ‘treatment’ for the disease itself. They often wrongly believe that endometriosis will be ‘cleaned up’, ‘dried up,’ or ‘cured’ using one of these treatments, but this is simply not true.
Ablation is the superficial burning away of endometriosis on the surface level. However, the gold standard treatment for endometriosis is excision surgery, because it actually removes the disease at the root. At many centers for expertise in endometriosis where excision is performed as the surgical approach, the rate of actual disease recurrence/persistence is around 7-20%. Many people find that their pain is significantly reduced or their quality of life has improved after excision. With ablation however, many people find their pain returns within just months after surgery. With ablation, disease persistence is fully expected, since the endometriosis wasn’t truly removed in the first place (and therefore persists).
Additionally, excision allows for the removed tissue to be sent to pathology for confirmation that it’s endometriosis, while due to the burning with ablation (and not the cutting out of tissue like with excision), the tissue is often unable to be sent to pathology for confirmation.
Due to the heat generated with ablation surgery, it usually cannot treat endometriosis on delicate tissues such as the bladder or intestines. If there is bowel or bladder involvement, the excision surgeon will often work with a multidisciplinary team, such as a general surgeon or a bowel surgeon, to excise endometriosis from these organs as well. Excision surgery is renowned in the field as being an extremely difficult gynecological surgery, requiring a high skill level to remove endometriosis from the delicate tissues, as well as separate organs that may have fused together due to adhesions. For example, the patient may have an obliterated cul-de-sac (the intestines fused to the uterus), ovaries stuck to the uterus, or the intestines fused to the pelvic sidewall. It takes careful skill to be able to tackle the complex surgical challenges endo presents.
The majority of gynecologists do ablation surgery, not excision. It’s estimated that there are only about 200 excision specialists worldwide, even though this disease affects 200 million people. There are many barriers to access excision, such as cost, location, insurance hurdles, long wait times, or lack of a referral due to inadequate education among doctors that excision is indeed the gold standard for care.
Excision surgery is oftentimes step one in the treatment of endometriosis. Endometriosis is a complex disease and may be present with other co-conditions like Interstitial Cystitis/Painful Bladder Syndrome, pelvic floor dysfunction, small intestinal bacterial overgrowth (SIBO), gut dysbiosis, hormone imbalance, or irritable bowel syndrome (IBS). While many people do have their symptoms diminish or disappear after excision surgery, others may need to address co-conditions to see more relief. Additionally, because endometriosis is a chronic inflammatory condition that can affect the full body, it’s important to work with a multidisciplinary team to address the disease from a holistic, full body approach.

How to Find an Endometriosis Excision Surgeon
Anyone can call themselves an “expert” in endometriosis, because there is no formal standard in gynecology to qualify to use that title. A doctor might call themselves an endometriosis expert, but is only doing ablation or is only prescribing hormone treatments, and doesn’t even do excision.
A good endometriosis doctor is a highly skilled, high volume physician who understands endometriosis and how to properly diagnose and treat it. Often they solely treat endometriosis and don’t practice obstetrics or general gynecology at all. Even among doctors that do excision, their skill levels and experience vary. Many people are also choosing to go to centers that exclusively perform excision surgery as a component of their multidisciplinary approach to endometriosis, such as the Center for Endometriosis Care in Atlanta.
iCareBetter and Nancy’s Nook are two great starting places to find an excision surgeon. Even if you find a surgeon using their lists, it’s still important to vet the surgeon and ask questions to make sure they have the appropriate skill level to treat you. Also, just because you have surgery with one of the doctors on their lists doesn’t guarantee that you will be pain free afterward, that you won’t have complications, or that endometriosis won’t persist or recur. Likewise, having surgery with an excision surgeon that you found and vetted that aren’t on their lists doesn’t mean you are guaranteed to have a bad outcome. Some excision surgeons do not have a social media platform, are not well-known, or work at academic institutions and rely on referrals instead of advertising to find patients. However, remember that *anyone* can call themselves an expert in endometriosis, so if you do find a surgeon that isn’t on one of these resources, it’s even more vital to vet the surgeon, and ask questions to learn their success rates, complication rates, rates of reoperation/recurrence, ability to treat complicated cases, etc.
- iCareBetter – This platform helps connect patients to endometriosis surgeons via a rigorous peer to peer double-blind vetting process for their surgical and excision skills. “With iCareBetter, patients can ensure their voices are represented in the doctor search process. And they will be able to choose their surgeon based on specific case skills and needs, such as thoracic endometriosis, bowel or bladder involvement, diaphragmatic endometriosis, superficial to deep disease, endometriosis-related infertility and more.” This platform is pretty new, so right now they don’t have many surgeons listed, but this list is growing as they vet more surgeons!
- Nancy’s Nook Facebook Group – This private Facebook group has a list of excision specialists worldwide in the Files section, and in another file Nancy’s Nook explains how the surgeons are chosen/qualify to be put on their list. This is where I found my excision surgeon. You can use the search tool in their Facebook group to see reviews people have posted of these surgeons.

No one knows the cause of endometriosis, but evidence is mounting that it is not caused by retrograde menstruation. Retrograde menstruation is when menstrual blood leaks out of the tubes into the pelvis and these bits of endometrium implant themselves in the pelvis where they land and grow into endometriosis. This 100-year-old theory has never been proven and has so many holes in it at this point that the likelihood of it being true seems almost impossible. Unfortunately, many ineffective treatment options are based on this still unproven theory.
While there are several theories to the cause of endometriosis – and there may indeed be multiple factors and causes playing into why a person has it – the best fitting theory of origin is Mulleriosis. This proposes that endometriosis is due to a developmental defect in the formation of the Mullerian duct system when we are embryos. The Mullerian duct is the very beginnings of the female reproductive system. Cells that are laid down during its formation may have abnormal migration (they may not go to the right spot) or abnormal differentiation (when a cell changes from one cell type to another) and later develop into endometriosis.
In fact, endometriosis has been found during autopsy in some female fetuses (who died for other reasons) at around the same rate, 10%, that it is found in the female population today. The theory of embryonic origin explains:
- how endo can be found anywhere in the body.
- how endo has been found in around 20 biological males. This is because as fetuses have both the male and female reproductive tracts during the first 6-8 weeks in the womb. One regresses and the other develops, so the fetus becomes either male or female, continuing to develop that specific tract. However, cells from the track that regressed can remain behind.
- why endo is found in embryonic patterns in the body, doesn’t typically spread, and has low recurrence after true excision.

- Ep 15 – What Causes Endometriosis?
The standard of care for endometriosis is disgraceful, especially for a disease that affects 1 in 10 people assigned female at birth. We need a cure. We need recognition. We need to go to the doctor and be taken seriously when we say we are terrified to get our periods because of the crushing pain that it brings. We need funding for endometriosis research. We need education in schools and even among doctors that period pain is not normal, painful sex is not normal, and painful bowel movements are not normal. It shouldn’t take 10+ years to be diagnosed with such a common disease, and once diagnosed, we should have access to excision to remove the disease from our bodies, instead of being offered subpar treatments based on misinformation. Some doctors even refuse to treat people with endometriosis who are not experiencing infertility or trying to get pregnant, completely disregarding that the other symptoms such as pain, fatigue, and digestive problems are severely diminishing our quality of life.
Not only do endometriosis patients grapple with chronic and often debilitating pain that ravages our lives, often affecting our relationships, our careers, and our mental well-being, but we face dismissal and lack of education from the very medical professionals who we are supposed to turn to for help. The psychological impact on us is double. We are weighed down by the crippling symptoms and lack of treatment, and weighed down again by being told that it isn’t real and that we should see a psychologist for what these medical professionals perceive as “anxiety.”
Many of us with endo begin having symptoms from 9, 10, 12 years old. It is heartbreaking to me that from such a young age, we go through so many trials and tribulations because we are fighting not only against endometriosis, but against a system of misinformation, dismissive doctors, lack of access to expert care, all while battling the pain, fatigue, nausea, doubt, and more.
The endometriosis community is an incredible group of womxn, nonbinary folx, and trans people, and we will keep advocating so that future generations don’t have to suffer as we have.
