This past month was Endometriosis Awareness Month. It was very exciting to see how many more individuals and providers were sharing amazing information about this disease that affects such a large percentage of our population. This was not always the case, and it is a sign we are moving in the right direction. Although there is more discussion around endometriosis, there continues to be a vast knowledge deficit about what this disease actually is, the symptoms associated with it, and how to properly assess and treat endometriosis. Despite our forward progress, it is disappointing to see information that we in fact do know about this disease, continuing to be part of the conversation. Based on the many people we treat, and those that have asked us questions, we thought it would be helpful to address some of the most common questions we are faced with as providers. Our hope is that this resource provides you with validation that your array of symptoms are likely not normal, or perhaps, this resource will be shared with others who are struggling, or may have been dismissed in the past. 


One of the most important aspects of being a specialist in this field, is to understand what endometriosis actually is. Probably the most common question asked is What is endometriosis? When reading posts online, listening to lectures, podcasts, or reading articles, this is always defined at the very beginning. 


Frequently Asked Questions 


#1 What is endometriosis? 


Answer #1 Endometriosis is a disease where cells that are SIMILAR TO endometrial cells (the cells that line the uterus) are found outside of the uterus. The important difference is that these cells are NOT the same cells that are found in our uterus. This has been an important piece of information in better understanding this disease. The most common theory for endometriosis has been retrograde menstruation (where menstrual fluid reflex through the fallopian tubes into the abdomen and pelvis where they cause a myriad of symptoms, most commonly painful periods and a common cause of infertility.) 


Interesting fact: retrograde menstruation is thought to occur most of the time, so why are only ten percent affected? 


Because endometriosis cells are NOT endometrial cells. Sampson’s theory of retrograde menstruation may at BEST provide one reason these cells may be present outside of the uterus. What it does not explain is how these cells shifted from an endometrial cell to an endometrial-like cell, if that is even how they got there in the first place. These cells are affected by estrogen which is why many symptoms start around puberty and may improve during menopause, and why men are rarely affected. 


Although many have thought that endometriosis is a “gynecological” disease, ongoing research is currently showing that endometriosis is more consistent with an inflammatory disease.


#2 Is endometriosis an auto-immune disease?


No, endometriosis is not an auto-immune disease. Although many with endo do suffer from autoimmune diseases, endo itself is not. Autoimmune diseases occur when the body attacks itself. This is not what is happening in endo, in fact, in some ways the opposite is true.


#3 What are the symptoms of endometriosis?


What most people know of as the classic symptoms of endo are painful periods and infertility. What many people do not realize is that endometriosis is an inflammatory disease that can cause symptoms across a number of different systems. Listed below are a number of other symptoms associated with endometriosis. Surprisingly, some people do not have painful periods or infertility, but present with these issues instead. 


**It is important to remember that these symptoms can be due to a variety of other reasons that have nothing to do with endometriosis and working with an educated practitioner to understand how these symptoms may or may not be related is highly recommended. 


  • Digestion – IBS type symptoms including constipation, diarrhea, or both. Abdominal bloating, abdominal pain, small intestine bacterial overgrowth, discomfort with eating, and painful bowel movements (dyschezia).
  • Urinary – pain with urination (dysuria), urinary urgency, and urinary frequency. Some may call these symptoms “Interstitial cystitis.” 
  • Myofascial – pelvic floor dysfunction or pelvic pain, painful sex (dyspareunia), back pain, hip pain, or more profuse generalized symptoms throughout the body, many get diagnosed with having fibromyalgia. 
  • Psychological – endometriosis increases one’s risk for developing anxiety and depression. 
  • Immune system – endometriosis can be correlated with other auto-immune diseases, although endometriosis is not an auto-immune disease itself. 
  • Pelvic floor dysfunction – majority of those with endo have pelvic floor dysfunction which can result in pain and contribute to urinary, bowel, and sexual dysfunction. 
  • Other – brain fog, fatigue, right shoulder girdle pain, shortness of breath, or coughing up blood during your period. These last few symptoms are related to thoracic endometriosis syndrome – the most common extra pelvic site where lesions may be found and are usually around the time of your period, where as pelvic endometriosis can present with symptoms at any point in the menstrual cycle, although typically begin around your period. 


#4 My doctor said I do not have endometriosis because of ___________ (fill in the blank):

  1. My periods aren’t painful enough
  2. Nothing shows up on imaging
  3. My pain is throughout my cycle not just during my period
  4. My periods aren’t heavy
  5. They didn’t see anything during surgery
  6. I don’t have infertility problems



  1. Not all women with endometriosis suffer from pain as their primary symptom or experience pain in the same way. If there are enough symptoms present, a well educated practitioner that specializes in endometriosis can help you create a proper plan of care which may or may not include surgery, but your symptoms are real and they will help you to understand the cause. 
  2. Imaging often does not show endometriosis. Depending on who performs the imaging and who is reading it, there may be indications of endo, such as pulling of organs or improper placement of the organs. The gold standard for diagnosis is laparoscopic surgery ideally with an experienced excision specialist.  
  3. Classically endo is described as painful periods, but many describe symptoms worse around ovulation, or just before their periods. It may start out just around your period, but may progress into more frequent episodes. The lesions themselves are innervated and are pro-inflammatory and can cause issues outside of your period. 
  4. Endo is commonly thought of as an ‘estrogen dominant’ disease. While estrogen is a mediator of endo, it does not cause endo. While many do report heavier periods, there are a significant number of those that do not have heavy periods. 
  5. This is a big one and one of the hardest to conceptualize. The last thing you want to hear is “we didn’t find anything,” coming out of your procedure and unfortunately, this happens all the time. The issue is this, your typical OBGYN has learned about endo of course, but has not had the opportunity to do in-depth training about this complex disease. It is not their fault – they are delivering babies, handling vulvar infections, doing routine PAPs, among so many other things. That does not mean you cannot find a good doctor that does all of these things, but it is harder to find one. Endo presents in a variety of forms and different doctors use different techniques in how they search for endo. They take different approaches on what they define endo as. For example, fibrotic endo which is often found later in life, or after going on hormonal suppression meds, may appear white or scar-tissue like, just different than the classic lesions and it is not said to be endo, but it may be causing dysfunction. 


#5 Do I still need to be on birth control after my excision surgery?



This is a tricky question because every person is different. Your doctor should review with you what they would recommend. While birth control is not a treatment for endometriosis, it is often used to help with symptoms (for some it does) and some surgeons will recommend something after your surgery to help delay the need for another surgery depending on what they see and your personal case. I do advise you to ask your doctor questions, especially if you’ve had bad experiences in the past – what are your options? Is it absolutely needed and why do they believe this is the right choice for you? This should be a discussion between you and your doctor, and if it is the right thing, ask what your options are regarding them and voice any hesitations or concerns you may have. 


#6 I had an excision surgery by a vetted doctor, my endo symptoms are back, could this be endo again?



Unfortunately, this is a possibility. This does not mean that it is for sure endo – especially if other areas have not been fully ruled out or treated such as pelvic floor dysfunction, GI issues, diet, and lifestyle factors. We still have a lot to learn about this disease, we know genetics and inflammation are involved, and this is a great place to start exploring. Prior to the onset of recurring symptoms have you back-tracked on your diet and lifestyle because you were feeling good? Did other health concerns pop-up or were there ongoing stressors that were not dealt with? This is not an exhaustive list of reasons, nor may any of these reasons be the source for you. It is best to have a conversation and workup with your doctor to explore next steps. 


#7 My doctor recommended a hysterectomy, I thought endo could not be treated with a hysterectomy?



It is correct that a hysterectomy won’t do anything for endo. However, if it is suspected that you have something called “adenomyosis” it may be recommended as this IS a treatment for adenomyosis. Adenomyosis is sometimes referred to as a close relative of endo. It is essentially endo in the muscle layer of the uterus. The majority of women with adenomyosis also have endo, though not all do. If this is the case, the choice to get a hysterectomy is a big one and depends on many factors including future fertility. If fertility is not a concern of yours – meaning, you already have children and do not want more, or, your pain is so debilitating and you have tried everything (including excision of endometriosis), or just have contemplated other options of fertility and you and your doctor have decided this is the best decision for you, then yes, a hysterectomy in addition to excision of endometriosis (if present), would be a valid treatment option. 


#8 I have been told that pregnancy is a cure for endo, does this work for everyone?



No. While there are people who become pregnant (because they wanted to become pregnant), and their symptoms improve during or after their pregnancy, we should be thrilled – for them. This should in no way be considered a recommendation for others experiencing endo. First, some people cannot get pregnant because of endo, some do not want to be pregnant (now, or ever), and many people do not get better with pregnancy. Yet, this is still something that continues to be suggested (I heard it just the other day!). 


#9 How should I prepare/what should I expect after my lap?



This is a great question, and we recently wrote a blog that you can read called “What to expect after laparoscopic surgery for endo: Part 1.” Of course, we are here to answer your questions and are happy to help. If you are seeing a pelvic floor physical therapist, ask them about any local resources they may have. If you have not seen a PT yet, please start there. If you need help in finding someone to work with, we also offer digital health sessions to answer your questions, and help you find resources as well.
