300+ Hypothyroidism Symptoms…Yes REALLY

300+ Hypothyroidism Symptoms...Yes REALLY

Who knew that little butterfly-shaped thyroid gland at the base of our necks could affect our lives so completely? Don’t underestimate the power of that little gland. It is the master control center for the metabolic functions of every single cell in your body. Therefore it has the power to disrupt every part of your body and to produce profound changes in every aspect of your life. Scientific research links hypothyroidism to heart disease, diabetes, kidney disease, gall bladder disease, liver disease, cancer, and Alzheimer’s. According to the World Health Organization, there are 750 million people in the world with thyroid dysfunction. Over half are presumed to be unaware of their condition. Despite research connecting an underactive thyroid to some of the deadliest diseases of our time, the hypothyroidism epidemic sweeping across the globe has gone largely unrecognized by the mainstream medical community. Are you sure you are ready for this long pathetic list of symptoms?

My hope is that this post finds the millions of people worldwide who are not aware of their condition. They are suffering from multiple health complications but they have no clue their thyroid is to blame. Their doctors are prescribing medication after medication for illnesses that could be treated by addressing the underlying hypothyroidism. It is a tragedy.

Then there are those who have been diagnosed with hypothyroidism and treated with thyroid hormone replacement medication, however they still suffer from many of the symptoms on this list. Their doctors have no idea the real reason for their ill health is the improperly treated hypothyroidism. They too are being prescribed multiple medications for conditions that could be treated by proper thyroid treatment. Others are mistakenly considered hypochondriacs and prescribed sleeping pills and anti-depressants by their doctors. Others are told their symptoms are just part of normal aging and shrugged off as unimportant. Doctors are relying solely on laboratory tests for diagnosis, not investigating fully the patient’s medical history, symptoms, family history and thorough physical exams. Does this sound like you? It may be time to change doctors.

The following individuals and organizations are some of the top thyroid health experts in the world. My list of 300+ symptoms is a compilation of their lists of hypothyroid symptoms along with additional symptoms I have found in my research.

Thank you to Dr. Mark Starr for the comprehensive list of hypothyroidism symptoms in his book Hypothyroidism Type 2: The EpidemicThank you to thyroid pioneer Dr. Broda Barnes for his thorough description of symptoms in the legendary book Hypothyroidism: The Unsuspected Illness Thank you to thyroid patient advocate Mary Shomon for her extensive list of hypothyroidism symptoms in her book Living Well with Hypothyroidism: What Your Doctor Doesn’t Tell You…That You Need to Know. Thank you Janie Bowthorpe for her Long and Pathetic List of Symptoms. Thank you also to Thyroid UK for providing great resources.

Every person will present with a different combination of symptoms. The severity of each person’s hypothyroidism will also determine the severity and number of symptoms they experience. Untreated hypothyroidism worsens with age with worsening symptoms. Don’t be led to believe that symptoms from this list are not connected to hypothyroidism, because they may be in your case, even if your doctor doesn’t know it.

Do you suffer from any of these symptoms?

Are you prescribed medications for symptoms listed below? Are you sure your doctor is aware of the connection of these symptoms to hypothyroidism?

Are you being treated with thyroid replacement medication but still suffering symptoms?

Do you have a family history of thyroid disease, heart disease, diabetes, autoimmune disease, cancer and/or Alzheimer’s? Please read on.

  1. I have been having issues here lately . Decided I would try thyrozavan cow thyroid was on it about a week . Had to quit heart was doing weird stuff . Normally take NP thyroid . But was trying to find something other than NP because of the issues they are having. Any way I have quit taking meds for a couple of days because I was shaky and heart racing and panicky. So hopefully in a few days I’ll be back to normal . Also have been doing a heavy medal detox . I may be needing less meds

    • Samantha, I feel we are in a similar position. I, too, am working on a detox ( lightweight as my adrenals are weak). My number one problem is brain fog/mental cloudiness/confusion. I have sky high RT3, do you? What’s been helping you?

  2. Sara Utter says

    I have over 240 of these symptoms. I have been diagnosed as hypothyroid for the last three years, but have been tested repeatedly for years prior, but I always get told that I am within “normal” range. Typically, I am right on the cusp of T4 being considered low (.8 is low normal, I am .9), TSH is usually high, T3 is low. I get put on medications (Naturethroid, Armor Thyroid and Levothyroxine) and after a couple months, when my levels are checked again, I am taken off of the medication because my levels now say I am hyperthyroid. Levothyroxine did absolutely nothing for me. With Naturethroid and Armor Thyroid, I am at least able to finally lose weight. I have been diagnosed with narcolepsy most recently, so I am still tired all of the time, which was what I was most looking for help with.

    • julie cook says

      I have been on thyroid meds for eleven days. Other than feeling headachy a couple times my acid reflux is better,constipation better, not so tired.I am overweight and have fluid retention.while lot of other symptoms. How long for other symptoms to go away?

  3. I have another one to add to the list – changes in body fat percentage. More and more people have access to scales which measure body fat nowadays. Over a 2 year period, before diagnosis, my body fat % gradually changed, increasing by 8%. I only gained a little weight in that time, a few pounds, but lost strength and muscle, and gained fat. I was doing strength training 3 times a week but was finding it increasingly hard work, and was regularly having to reduce the amount of weight I was lifting. After 3 months on NDT I have reversed about half of the change so far.

  4. I was diagnosed with under active thyroid 3 years ago. Was given levothyroxine but didn’t get on with it.
    Use a natural supplement.
    I,m tired mainly by evening and have frequent joint and muscle pain.
    Theses things don’t bother me too much, but for a while now I wake early morning, heart racing , hot and feeling nauseas, is this related to hypothyroidism?

  5. I know this is an older post, but I want to say it seems many of the doctors dont agree on symptoms of hypothyroidism. I’m talking about Carpal tunnel specifically right now. I have read numerous articles on Carpal tunnel and hypothyroidism and my own Dr has told me the same. It’s due to inflammation on the nerves. Not only can it happen with hypothyroidism it also happens during pregnancy for basically the same type of reasoning…out of whack hormones. If you think about it, it makes sense. If your thyroid controls everything going on in your body, why wouldn’t it mess with carpal tunnel and all of the symptoms listed? It makes more sense than not. If that was my Endocrinologist, I’d go find another. I hope this makes sense. My hands, wrist,fingers and even my foot is really bothering me right now and it’s hard to concentrate and type. I hope you got your problem resolved

    • Cynthia Jones says

      Remember the very propensity for those with autoimmune disease to get other autoimmune diseases like RA which could explain pain.
      However, sticking with Hashimoto’s and hypothyroid, I can’t overemphasize the importance of strict adherence to the autoimmune protocol. It’s not that difficult to get started if you start with high quality fats like MCT oil, avacado, etc. to overcome hunger and the cravings natural from depriving your body of all the things currently doing you in.
      I can eliminate pain entirely If on this way of eating. Search aip to see many lists. If I slip I wake up in terrible pain the next day.

      • Hi Cynthia,
        Been trying to start AIP while pregnant (all the cravings!) and it’s definitely not easy. Any tips? Can’t have avocados as they are high in histamine….

      • Hi Cynthia,

  6. I have been hypothyroid for a few years and had been taking Naturethroid. I was switched to WP thyroid from Jan 2019 thru May 2019 and back to Naturethroid in June 2019 when it became available again. Since then, my hair is excessively shedding, extremely fatigued with joint pain. My latest test is showing me moving to hyperthyroid. I was also taking big doses of biotin at test time which I later read can affect the test. My doctor thinks it is menopause and not connected to thyroid and won’t let me go back to WP. I read somewhere that the Naturethroid has been reformulated and has been causing challenges. Anyone else have a problem?

    • I’m in the Facebook group Hashimoto’s 411 and since the reformulation, numerous people with Hashimoto’s have “crashed,” as they say, and had all types of issues, so Naturethroid is no longer a recommended med for us. I was on it years ago and did fine; switched to WP Thyroid when it became unavailable and been on it since.

  7. I suffer a good majority of this list. To the point I have been told not to work anymore and just live on benefits.
    I have never done so because I want more for my life than to live on benefits just because of this horrible nightmare. Every day is a struggle but I keep going with a smile on my face while I do it.

    • Catherine Wallis says

      I have had hypo for 11yrs. I have many of these symptoms. I’m really over people who tell me hypothyroidism is just an excuse to be fat. Why would I ever choose to look like this lol. My own family have no understanding. Luckily my bf is very understanding if the housework doesn’t get done. I’m on levothyroxine and I’m just pretty much used to feeling like crap

  8. This is incredible….but to be VERY clear, these are all hypo symptoms? I have mostly hypo symptoms, but am hot all the time and it makes me confused as that’s usually a hyperthyroidism symptom.

    But according to this, it could be a hypo symptom too?

    • These can be both hypo and hyper symptoms. I am hypo but often find I have symptoms that would “classify” as hyper. Also Rachel not sure how old you are but perhaps you are peri or menopausal

  9. Eva Gwyn says

    I have 2 others for your list that we have discovered from our online group. 1. is a pulsing in the abdomen. Many of us have it. 2. is a pain in the middle of the chest, sternum area.

    • Jody Thomas says

      I am hypo and I have both of these

    • Hi. I am so incredibly happy that I stumbled upon this site!! I am having MAJOR joint/muscle pains, tingling hands and feet, muscle weakness, air hunger omg my list is endless. My Endocrinologist says my TSH is in the “normal range” and cannot do a thing to help me. I have had thyroid issues for the nearly 16 years and have never felt like this when I was under the care of another doctor. This all started once I started seeing this doctor. What in the world should I do next? I would greatly appreciate it if you could give me some advice. I just don’t know how to convince this doctor that it’s Hypothyroidism 100%.

      • Beverly Dupree says

        Join Thyroid Advocates on Facebook. Not doctors but a wealth of info from years of people with thyroid problems. Testing just T-SHIRT does not give you accurate info. You can ask questions and get feedback from these people. Wishing you the best.

      • Beverly Dupree says

        TSH not t-shirt, dang autocorrect.

      • Ellie May Not says

        Hi Summer! You may also want to rule out B12 deficiency and/or Pernicious Anemia (PA) as the symptoms overlap with hypothyroid and many individuals, myself included, have both Hashi’s/hypo thyroid and PA. Serum B12 levels are not always accurate and MMA (methylmalonic acid) is often used in addition to serum B12 testing. Turns out that this is yet another forgotten disease and overlooked by many healthcare providers.

      • I had the same problem till I told my doctor to STOP generalizing. I told just increase my dose and see what happens. He finally did and my symptoms improve. He decided to increase it one more time. I didn’t see him till three months later. When he saw me he said, WOW you look like a different person. I felt good for the first time in along time. I went from .88 to .125 dose. My number were coming out normal at .88 and now at .125 they are still coming out normal at .125.

    • I have that sternum pain. It actually hurts to the touch at times.
