Could Our Thyroid Be THE KEY to Solving Endometriosis or Perhaps It Is Where It All Began?

CEO Founder & Creator of the REACH© Technique, Endo Empowered and the Endo Wellness Technique program.

A few months ago I wrote an article about the thyroid and its significance in controlling hormones. What I didn’t perhaps realize is just how important the thyroid is and how it may explain why we have Endometriosis.

It all began with an annoying thing called allergies. I actually thought I would be fine this year but they were shocking! I had really bad, itchy eyes and they were so swollen and sore! It was horrible. Anyways, so I left a comment on my Facebook page, asking anyone if they could give me a solution. One of the girls suggested that it might be related to my thyroid. I hadn’t even considered the connection, to be honest! I have also not been that good with taking my kelp, as I suggested in my previous post and have totally underestimated the importance of our thyroid in the whole picture of Endometriosis.

A healthy thyroid produces hormones that control a person’s metabolic rate. In essence, the thyroid acts as the body’s gas pedal. A hyperthyroid (overactive) causes the body’s systems to run too hot and too fast. A hypothyroid (underactive) causes the body’s systems to run too cold and too slow. The effects of low thyroid and low body temperature can be devastating because for every one degree decrease in body temperature the base metabolic rate decreases by approximately 6%. It is not uncommon for a person to have an average temperature that is two to four degrees below normal. This correlates to a 12%–24% reduction in overall metabolism. No wonder we feel tired and depressed!

Here is a list of symptoms with underactive thyroid:

  • Thrush – or Candida… this is massive. Please read this article on candida and how this in turn affects Endometriosis!
  • Allergies
  • Heart palpitations
  • Sore breasts
  • Stomach bloating/digestive problems
  • Nausea
  • Motion Sickness
  • Itchy skin
  • Low sex drive
  • Depression
  • Weight gain or difficulty losing weight
  • Brittle, split nails
  • Swelling puffiness of the eyes, face, arms or legs—I can totally relate to that one!
  • Poor concentration
  • Menstrual problems


Okay, I don’t know about you but I have had 99% of those in my life or at the moment! Wow!

So, what are some of the causes of hypothyroidism?

  • Mercury from our teeth!
  • Diet containing wheat, sugar and caffeine. Wheat and Gluten intolerance has been closely linked to hypothyroidism. Millet should also be avoided.
  • Soy is terrible for the thyroid!
  • Toxins in the environment/ food etc.
  • Lack of iodine and selenium in our diets, due to poor soils (common in New Zealand and Australia)
  • Ongoing medication and drugs such as the contraceptive pill can influence our thyroid function.
  • Hashimoto’s disease—this is an auto-immune disease where the body attacks the thyroid gland, making it inflamed and less likely to do its job.

To me it seems fairly obvious based on these two lists that hypothyroidism is closely linked to Endometriosis. Question is, what came first? The hypothyroidism or the Endometriosis? Hmm… interesting!

In my previous blog entry I talked about how our immune system may be the ultimate reason why we have Endometriosis. So, do we therefore also have Hashimoto’s disease? Is it all just the immune system that needs to be addressed?

Could it be that we developed hypothyroidism from mercury, the pill, soy, toxins, lack of iodine or selenium (they feed selenium to cows to avoid them getting endo!) and then… we developed Endo because of that?

It would be interesting to find out just how many of us have hypothyroidism along with endo to assess how closely related the two really are.

Thing is, many of us probably don’t even realize we have it. So, I will be doing a test with you next week—gotta do it on the second day of my period. This will assess whether I have hypothyroidism for sure… even though I have all the symptoms. Then you can do it too, when your monthly comes around.

Then I will be exploring some natural alternatives to treating it because once again… the last thing I want to do is take a funny hormone to regulate my thyroid! Now that would be slightly contradictory!

Would love to hear your thoughts on this stuff! It is so interesting to see how it is linked together!

What is even more interesting is that it is very much hereditary….

    I was diagnosed with Hashimoto at the age of 14. It started when I was about 9 – that is when I first recall having weird flare ups and where my weight gain began. I am currently 17 years old. Ever since I gotten my period at 13 I experienced terrible pains (I still do). My Mother and I believe that I have endometriosis or Polycystic Ovaries. I strongly believe that the thyroid effects your reproductive organs. Just think about it, your thyroid does control your hormones, which in turn helps things down there~ Anyways, Hashimoto is known to cause menstrual cycle problems, anything from sever pains to irregular periods can be linked to underactive thyroid production. For those suffering with Endometriosis I suggest going on a dairy free diet and try to cut back on the sugar. Not only does this help with hashimoto it can also sooth those awful period pains! I hope I was some help to someone!

      You’re definitely right. To add on to this, thyroid affects fertility as well. A recent research study was published in the Journal of Clinical Endocrinology & Metabolism. Women with low thyroid hormones had high levels of unexplained fertility when compared to women with thyroid hormones more in the acceptable range.

    I was diagnosed with endometriosis 23 years ago and developed Hashimotos 3 years ago! Interestingly despite being on ‘conservative’ treatment for my endometriosis and thyroxine I have spent the last week in hospital and they found out the endometriosis which was apparently being controlled, has spread and fixed by ovaries and caused all sorts of problems!

    So perhaps my condition worsened once diagnosed with Hashimotos? Who knows? It is only having been in hospital that the link has been made!

    I have hypothyroidsm and recently just been diagnosed with endometriosis. The period pain cause by the endo started at the same time my face got puffy by the hypothyroid. Funny how fast our body reacts and realize that theres something wrong with the thyroid..

    I have hypothyroid and currently stage 4 endometriosis.I feel very sick…help?

    I have had Endo and adenomyosis and been struggling for years. On my last surgery for my Endo my biopsies came back abnormal for hyperplasia. And my six-month follow-up she was amazed by the amount of tissue that was in there that accumulated in six months . Not really sure why that would be. I would say over the past 10 years and everything has just gotten a whole lot worse in every way. I hope this isn’t a dumb question but I’ve read many times that people typically with endometriosis are usually thin. So I am confused how a condition like hypothyroidism would also be a contributing factor. But that probably is a mess and I am sorry if it sounds like it ignorant comment definitely not trying to upset anyone. Because I know just because you have hypothyroidism doesn’t necessarily mean that someone is overweight. I have been desperately trying to figure out what the underlining cause Of all my health problems. Over the past 10 years I have been diagnosed with scleritis and optic neuritis/papalitis and Reynalds of hands and feet. I do have a lot of got problems my son says I’m the gaseous female he’s ever met . I have wondered about a gluten issue but have never looked into it too much . I have severe joint pain off and on. My bloodwork such as hemoglobin, platelets, white blood cell count, red blood cell count and my C3 and C4 are typically low when my joints are hurting. Some would say well maybe her hemoglobin is low because of your bleeding with your periods. Maybe at times but typically the pattern I’ve seen is when I become extremely stiff and my joints are hurting and I’m swollen everywhere is when my blood work is always low then. Thank you for taking the time to read my message any input or thoughts or comments would be appreciated. I learn something new every day and would love to hear your feedback

      I believe I have hyperthyroidism and endo. I had constant cyst get so large the would rupture and leave me hospitalized, they finally did my laproscopy and I was filled with endo. Needless to say it’s been a constant battle with combating the symptoms in a healthy way. I’m with you though, I am a very thin female- endo and eating a endo friendly diet I.e trying to stay sugar free dairy and gluten free has left me even tinier than before. I’m trying to work on gaining it back but with the IBS link- it’s nearly impossible. Endo is very heartbreaking but I too think there is a cure some where.
      Constant pain is debilitating and can also cause you to shed weight off. Best of luck to everyone, I love this forum!

      • Katie

        That is so crazy because I have all of those problems, I have my surgery on October 3rd and I’m nervous. I have IBS also and recently been diagnosed with hyperthyroid. Hope all gets better it really is a deep pain both physically and emotionally

    I went to see my lady doctor about the pain I was having. She said it is probably endometriosis but she didn’t want to do the surgery to find out for sure if that’s what I have. She wanted to put me on birth control and just be done with it. I refused to go on anymore pills because I feel like that’s how all of this started. Since then I suffer through the excruciating pain of endometriosis bUt Im afraud that if i let it go that it will get worse. I’ve also had my thyroid checked because I have heart flutters, especially when I’m on my period. The blood test came back normal. I feel like I’m not getting the help I need. Can anyone point me in the right direction. I’m lost with all of this and I dont know how to get help.

      Hello diana,

      Please see my comments/reply to a previous post above. Wife was in same position, now life transformed.

    • Lorin Driskell

      One thing is for sure. Three doctors have forced me on BCPs because I refuse to do depot lupron shots to force me into menopause. While they may stop your “ovulation” BCPs DO NOT cure pain in any way shape or form. I currently love my birth control. But it has nothing to do with pain. Higher the estrogen, the more prone you are to candida and cysts…. Look into progesterone only.
      BCPs will not cure the pain. 🙁

    I was diagnosed with Endometriosis about a year ago. My symptoms startet 6 months before, at the age of 28.

    Because the Western Medicine had no satisfying treatment, I started my “Natural Journey” whith a better diet: no gluten, no sugar, no meat and dairy products, no processed food, no alcohol, no coffein, no more pills, no hormones. At the beginning it was really hard but just some days on my diet, the pain was less.

    What I just wanted to say is, that I don’t know if my thyroid is working well but a few months ago, when I had pain every day, I also had some problems swallowing in the morning or during the day. But since I really take care of my body, this problem has disappeared.

    I really appreciate what you do. There is a long way to go until my symptoms and pain are completely gone and my body is healed again but I think it’s the only way.

    I was diagnosed with Endometriosis via Lap when I was 19. Three years later I had to have 1/2 of my thyroid removed due to a pre-cancerous growth. I have always wondered if the two are connected. This is something that medical science may want to look in to a bit more.

    I was diagnosed diagnosed with hypothyroidism 10 years ago.
    I just got diagnosed with stage 4 endodemetrosis

    • Melissa

      Hugs Jill. I hope you have found the information on my site can help you with the endo 🙂

    I also have hypothyroid and am now getting a laparoscopy to confirm that I have asymptomatic endometriosis (both of my fallopian tubes are blocked). I took birth control pills for years and also have fillings. I’m currently taking synthroid to help with my thyroid, but, frustrating since my numbers are in the “ok” range, but, I STILL have all of the symptoms I came in with…low body temperature, irregular period, depression, poor concentration, etc. I currently use fluoride free tooth paste, but want to look into having my fillings removed.

      Hi Sabrina!
      I have had endometriosis for years and I underwent an unsuccessful laparascopy in May 2014 in hopes of finding some relief. I was diagnosed with hypothyroidism in July of 2013. My doctor prescribed Synthroid for me. I took it for 3 months and I just felt worse and worse. I started doing some research on the internet and found out about natural desiccated thyroid (such as Armour, Westhroid, or Naturethroid). I had a hard time finding a doctor who knew anything about natural thyroid or how to prescribe it, but I finally found one. I have been on Armour since October 2013 and it has definitely helped my hypothyroid symptoms. I hope this information might help you.

    I am 30yrs old and have been struggling with Endometriosis now for nearly 12 years. I have been taking birth control pills continuously since then to avoid having a period to reduce the inflammation. It was around 1yr later that I was diagnosed with having hypothyroidism. My thyroid was so enlarged the doctor thought that I might have a tumor. I have been looking into ways to control the pain but have been unsuccessful. I have a family history of beast cancer so I hate ingesting all these hormones every day but when I try and not take the pills the pain becomes too intense. Thanks for starting this and for the tips that have been left.

    • Melissa

      Pleasure Beth and I hope you find a natural healing path that works for you. Perhaps look at detoxing your body of toxins and you might find the hormones sort themselves out 🙂

  12. Jenn

    Whoa. Eye opener. I found this article thru pinterest. I was diagnosed with endometriosis in December 2011. I had been complaining to my OB-GYN during our numerous visits that I was swelling like crazy and all she told me was to check with my GP. In May 2012 I was so tired I could barely drag myself out of bed. I finally went to the doctor in August and was diagnosed with Hashimotos. Looking back thru old pictures with my eyes so swollen you could barely see my eyeball I would say the thyroid starting messing up at least 4 years ago and that is exactly when my periods stopped and the pain started. Very interesting. Thanks for the insight. Now I am going to read more of your blog and see what kind of natural ideas you have for my thyroid. I am on my 4th medicine since August and its still not working!

    • Melissa

      Hi Jenn and glad you found me too 🙂
      I would recommend focusing on immune building your body. Maybe look into the mushrooms like Shitaki and Reisi and Chaga. I don’t know that much about Hashimotos but since it is an immune response by the body, I would also look at cutting out gluten, which creates inflammation and reduces mineral absorption in the body.

    Hi Melissa

    I think your site is absolutely fantastic and have only had a cursory look at it, so please forgive me if I have missed the right place to contact you. I wanted to send you two links that may be of use to you and other users of this site that are in pain and looking for natural ways to help relieve or even cure endometriosis.

    The first link is to a site where the lady Alison discusses how she overcame endometriosis pain and regained hormonal balance through a diet and her pain and endo has completely gone.

    The second link is to a site where the women completely cured her endometriosis through Eastern methods and in particular the use of Chi Kung and Shaolin Kung Fu. The lady runs Chi Kung and Shaolin Kung Fu classes which are quite expensive, but I found some free videos of the technique on Youtube.

    Anyway, you may even know of these sites and links already, but I saw them and thought of this site and the comments of others who are suffering and in pain and thought I would share them.

    Hope they can be of some help.

    • Melissa

      Thanks for sharing Preet! I have contacted Alison and hopefully will share her story shortly! It is great to have these links as more encouragement for girls that there is a way forward 🙂 Much appreciated!
