My wife had thyroid cancer (which spread to the esophagus and lymph nodes). Now 17 years later, after the cancer and the thyroid were surgically removed, she's cancer-free and doing fairly well, but getting the right amount of thyroid hormone replacement has been a constant struggle. She's gained a bunch of weight, has low energy, and pretty much every symptom you mentioned of hypothyroidism. Getting that hormone dose correct is *tough*.

[@theanatomylab]

Sorry to hear about your wife! But glad they were able to deal with the cancer, and yes... managing those thyroid levels can be challenging...

[@kazbaz8645]

I had thyroid cancer. I put on three dress sizes after thyroid removal in around 5 months. I dont eat that much but am large. I was on the higher dose of normal thyroxine as it helps any thyroid tissue left not to grow back and have thyroglobulin test every year. So in theory I should of had a high matabolism but it doesnt work that way

[@Ennui000]

I suffer from pretty bad hypothyroidism, and I still can't imagine. My condolences, and good luck to you both!

[@andreac.1350]

I had a high TSH and my conventional doctor was only testing TSH and T4. Tried to lower my TSH with synthroid for 1 year and it just gave me horrible side effects and I couldn't even get above 50mcg. Went to a functional doctor who tested the entire thyroid panel and found out I wasn't converting T4 to T3, which they said was common for the medication synthroid. They put me on T3 and in 2 days I felt so much better. I decided to drop the synthroid and T3 meds and try a natural dessicated bovine thyroid supplement which naturally contains not just T3 and T4, but T1 and T2. In two weeks on that my TSH went in the normal range for the first time ever. Diagnosed hypothyroid nearly 20 years ago. Been on that for just about a year and it has changed my life. That plus cutting out grains and starches, eating mostly ketovore diet. I already ate whole foods only for years, but going protein-centric really made a difference. Hope this helps someone.

[@Berilaco]

I mean... this sounds tough but the only thing that really controls how much fat you gain or lose is the amount of calories that you eat

[@magentamagenta1274]

@Berilaco that’s a myth, calories are not created equal with how the body metabolises food. All foods are processed differently depending on the protein, sugar, fat, fibre, aminos. If you ate 1000 calories of processed foods that would be metabolised differently to a 1000 calories of high fibre and protein foods. If you eat 70 raw almonds the calorie content would not be metabolised because the fibre doesn’t get stored as fat. Then high carbs spike insulin which also impacts on how you metabolise foods. Then if you have elevated leptin it impacts on how you metabolise food. The body is complex it’s an unfair myth that all obese people are obese or struggle with weight loss because they eat to many calories.

I had surgery recently to remove a 20 cm ovarian cyst (along with the ovary, tube and appendix) but they also found a Struma Ovarii (tumour made up of at least 50% thyroid tissue) which I was completely blown away by how interesting it was. Completely shocked that a tumour could be so specialised in cells especially growing somewhere it’s not supposed to. Luckily mine was not secreting any hormones and was not cancerous. At 23 it was definitely a shock lol.

Pheochromocytoma is usually found inside or on the adrenal gland(s), but occasionally, one will be present pretty much anywhere in the body and flood the body with adrenal hormones, such as adrenaline. Yeah, things can get lost and set up shop in the wrong place or a mutation causes a tumor that produces things it shouldn't in the wrong place. Or in my case, I've long had a mass on my adrenal gland that does nothing whatsoever, so, no harm, no foul, leave the dog alone. ;) Meanwhile, my immune system took a dislike to my TSH receptors in my thyroid gland, turning it on full tilt. Hypertension, tachycardia, extreme rapid weight loss, Hulk level "irritability", heart failure, abdominal aortic aneurysm all came to visit. The last time I had a thyroid storm, it was right at the first peak of COVID and my pulse oximeter read 85, well, that and I was gasping like a fish out of water, convincing me to have my wife call an ambulance (I hate hospitals, they're full of sick people!). Doctor came in after testing and said, "I have good news, you don't have COVID". "Oh? What do I have then?" "A type of heart failure from your hyperthyroidism." "Oh, thank God it's only heart failure... Did I just say those words?" Doctor laughed with a bit of a hysterical tinge, "Yeah, but I understand". At the time, hospital beds lined the hallways and were double stacked in the elevator lobbies, with one floor overflowing with COVID patients.

I've been suffering from hypothyroidism since I was a pre-teen and the lack of thyroid function caused me to be depressed, tired, fatigued, in pain, chronically constipated, I had to quit track and gained weight. Eventually it progressed to such bad brain fog I thought I was hallucinating cause my brain was so slow to process things. Hair falling out, fragile nails always breaking, more weight gain despite exercising, falling asleep constantly, ended up having to drop out of college. I was diagnosed with Hashimotos in my late 20s after years of going to the doctor and not being taken seriously. I hope that if you do have it removed you find that the meds work well for you because if not your life will just be a different hell.

Hello from canada, love your channel. I was diagnosed with hyperthyroidism back when I was in my late 20s ( I couldn't figure out why I was so tired to the point of napping in the day; that's why I saw the doctor) . My doctor said they could do the radio active iodine treatment ; all I heard was radioactive. So I did some research. Initially I took one kelp pill a day, bringing it back to normal. My doctor said whatever your doing it's working. Sadly it didn't hold forever and got way out of control again. My voice would get hoarse and I would feel very weak. I was eating a lot and losing weight like crazy, my hips started to hurt as well as my shoulders to the point where I could hardly wash my hair or walk a block.The tremors were so bad I had to have my son put on some of my make up. Heartrate was dangerously high so I had to do the radio active iodine treatment ( they brought a pill into the room in a concrete block and left the room) Which in turn made me hypothyroid and have been on the synthroid rollercoaster ever since. So now in my 50's with menopause, age and hypothyroid my metabolism has the rate of a sloth. I breathe and I gain weight. The struggle is real. I have to work it seems like three times as hard to lose/maintain weight.

Thanks as someone with Hashimotos and having had a total thyroidectomy 11yrs ago at 46, it really sucks trying to keep my weight down to a reasonable level, but it was great to see what a real on actually looks like. Mine wasn’t picked up by the normal blood tests as my levels always came back as normal, but after an MRI for my neck it showed I had a large goitre pressing back into my trachea and the radiologist just wrote over 10 nodules (tumours) on each lobe , then my Dr did an antibody test and it showed how skewed my levels actually were, they said I had it for at least 10yrs as I was 47 when I had it removed, but it seems like autoimmune issues run in my family as both my sister and I have rheumatoid arthritis, but my Niece has Chrons disease, but she got hers under control by going completely plant based, she was able to stop the really nasty medication thy use for it.

[@voidmain9519]

Thank you. Could you please list the items of plant based food for Chrons disease??? It's very much needed for me and my sister.

Having only one half of my thyroid and only half of my thymus gland as well, I found this extremely interesting!! I know all about the blood tests. I get one every yr for the past 20+ yrs. I also have a nodule in my remaining half of thyroid gland, that is under watchful waiting to carefully monitor the growth rate. As a large nodule that was affecting my breathing and swallowing was the reason I lost the other halves. Thanks so much for this additional info!! I love your videos.

[@imwalt3439]

Great video! Cleared up a few things about my experience. Three years ago I just wasn't feeling normal. A life long runner, cyclist and weight-lifter, I just felt sluggish and even a 2-mile run was a struggle. My wife said I was just doing too much at age 63 but I had always done these things. I was also irritable, was having trouble sleeping and my mind always seemed to be racing and I couldn't concentrate. Told my doc, she ran a Thyroid panel and my TSH was high. Started with 25mcg of levothyroxine and TSH actually went up so we went to 50 mcg. Never felt better in my life. My sleep improved, my mind was clearer, even bowel movements improved. Best thing I ever did. Earlier this year I noticed I always felt like I wanted to go to sleep. I just wanted to lay my head down all day. TSH was a little high again so we went to 75 mcg and now all levels are perfect and I again feel great. Also found out my mom was on synthroid before she died and my sister also is, so this must run in my family. Thank you for this information

[@SlenderPunk]

learning about the endocrine system in my anatomy class right now, this is great review!

[@rubicg177]

As a secondary thyroid disorder patient, I loved this video. LO-VE-IT! The only thing I feel you have missed is to talk about thunderstorms or crises in which all hormone values increase or decrease dangerously at the same time. I suffered a crisis of this type in 2017 and it is really very difficult to find useful information for the patient. The type of information that clearly explains what is happening with the body and the mechanism of action, without going into the technical vocabulary.

[@eddierayvanlynch6133]

It would be awesome to see them do a vid on that 👍😎

[@missjimmyt88]

Snap, fully appreciated this video and had me understand my numbers, something my consultant always confused me about. Crisis is something I've always been intrigued about and would like to know a bit more about

Since you guys made the hormone related physiology and anatomy easy in your earlier videos , I like to know of the hormonal fluctuations that happen 'every once in a while' in us. Besides the notorious puberty , hormonal changes affecting organs and primarily behaviour to the according people.

[@jurassicaaaX_X]

Missed opportunity to talk about Hashimoto’s (autoimmune thyroid disease) and Grave’s disease. Also wondering why so many of us still feel very unwell despite the levels of all thyroid hormones being correctly replaced by medication.

[@christine3043]

Many feel unwell because they’re either on the wrong medication, or their doctors are not testing their free T3. Testing only TSH and FT4 is not enough. FT4 is converted into FT3 which is the active hormone. Some don’t convert it well so they need a T3 pill as well. You can have a normal FT4 level and feel crappy, but your FT3 could be low and that’s why.

[@PinkBunnyCorporation]

​@@christine3043 agreed. I am on the cusp of hyperthyroidism ajd its naturally improved over time. But i have to tell the doctor to order a true full throid panel. I get my tsh tested yearly. So i have loys of data points that make me feel good that its been going better each year slowly. But for those who need it get all the hormones tested. Reverse t3 also if they can.

[@EnderMoka]

I agree, hashimotos and Graves are the leading causes of hypo and Hyperthyroidism in the US. having one of the two increases risks for other autoimmune diseases, like a few people in the comments mentioned having. Hashimotos warrior here 💙🦋

See connection of h.pylori and hashimotos. See also MTHFR and gluten sensitivity and need for B complex METHYLATED since with MTHFR gene mutation a person cannot normally detox metals or convert synthetic B vitamins.

[@soapsoilandsunshine3241]

Thanks so much for this. I have Hashimoto's auto-immune disease (hypothyroidism). I went to the docs with a feeling of a lump in my throat. I was sure something was stuck there. Doc ran some tests and my T4 was on the low side at 10 pmol/L (Ideal is 9.0 - 19.0) and my TSH was 10.3 mIU/L (Ideal is 0.3-4.0). I was shocked at the diagnosis. I'm not overweight and felt my energy levels were just starting to dwindle. I went on a paleo regime immediately and I feel great (nearly 2 years in now). Gut "action" was very slow, and was the first improvement I noticed after starting on Thyroxine. Thanks for the great explanation. Oh and my thyroid anti-body levels were off the chart (>13,000).

[@mddell58]

1987 my mother had a brain tumor on the hypothalamus. Since they couldn't cut her brain in half to remove it, sadly, nothing worked. She lived 7 months from diagnosis. She was VERY healthy, & ahead of her time. I miss her greatly. My mom & I both had/have thyroid problems, & take Synthroid Rx for it. VERY important for every woman to be tested for thyroid problems, etc.

[@theanatomylab]

Thank you for sharing your experience. Sorry to hear about your mother❤️

[@lovinglife69]

I've been waiting for this one! Thank you so much for discussing this tricky little gland! My wife was losing a bunch of weight. Went to the Dr and he told us she had an overactive thyroid. Graves Disease. She had to take a radiation pill to try and "zap' it back to normal. After 6 yrs they are still trying to "level" her thyroid out. She may gain a few pounds in 3 months but she'll lose it as quickly as she gains it. She has all kinds of sizes of clothes because they will fit one month but the next they won't 😆 About 6 months after her diagnosis I was feeling tired all the time. I was thirsty all day long. Drinking water like I was in a desert! So I went to the Dr and he diagnosed me with thyroid cancer and a goiter. The left thyroid was removed. Before surgery, I had asked the Dr, "Oh no, does this mean I'm going to gain weight?" His reply was " maybe 3 or 4 lbs". 6 months after the surgery I gain 80lbs!!!! EIGHTY! Not 3 or 4! I wasn't happy and I'm still not happy about it! I'm HYPO & my wife is HYPER We take the same medication, Levothyroxine. She takes more of it. Like 175 one day and 35 the next. While I'll take 75. Which is weird to us because you'd think I would take more and her less. 🤷‍♀️ The battles between us when the A/C is on or when the furnace is on can be a challenge. Especially in the car. Because she is always burning up....hot. I'm freezing 🥶 Even laying next to her I can feel the heat off her body. Which when I'm freezing is nice 😁 This pesky lil gland can create havoc on your body! My cholesterol is high, I've had a heart attack since I was diagnosed, dry skin, I'm more forgetful, always feel weak, no energy, and it's hard for me to fall asleep. I'm up every 2 hours. When I do get sleep at night (about 6hrs) I could easily take a nap during the day. But the life of adulting doesn't allow me that privilege 😁 And I'm not even going to go into the constipation issues 😏 In 2019 I had weight loss surgery. The sleeve. I started at 306 lbs. Lost 90lbs. in 2 yrs. Slow but i did lose and was feeling great about myself. I got down to 212 lbs. I couldn't lose those last 12 lbs to say my life! Covid hit and I started gaining weight. I've gained 35 lbs. I'm trying to get back on track but it's hard. I'm not giving up. I'll find the right combination. So thanks again for this video and all that you do! Enjoy!

Great video! I love watching your videos! The way you explain everything is really amazing and easy to understand. Also, I have a question... Does hypothyroidism also cause temperature difference? My mom has hypothyroidism and sometimes she used to feel sudden cold and shivering (shivering from the inside), her hands and legs would turn cold and after massaging it for sometime she would be normal and sometimes she used to feel burning sensation even though she was on her daily thyroid pills. Though now it rarely happens..

[@johnshermandcdibak4284]

I really liked the simplicity of how you explained the blood tests. I have seen other thyroid tests (free T3 and T4, TPO, rT3, etc) and how are these important in the analysis of thyroid function? I have heard the pros and cons on these additional tests and how just running at TSH and T4 may miss a lot of info. Any info here would be greatly appreciated and thanks in advance.

[@margitwes6495]

I had my thyroid removed due to cancer in 2011. I was put on thyroxine and had bad reactions like muscle cramps,horrible headaches and a number of others. Doctor told me my body had to get used to it. After three months of misery and doing some research I found Armour, the very first thyroid meds developed 40 some years ago. It took to really put my foot down to get my doc to prescribe it, because she never even heard of it. How is that possible? Within 2-3 weeks all those bad symptoms disappeared and I'm feeling fine. Cancer has not returned and my weight is ok,little more than I would like,but I'm 71yo and I'm still a size 8.

My great aunt had thyroid cancer and honestly the amount of problems it caused body-wide was terrifying. I was to young to fully understand cancer, but I could tell she was incredibly sick. Unfortunately, the cancer spread to her brain and she passed at a young age, so I really didn't get to know her very well, but she was a really cool lady who worked with foster kids to try and improve their lives. She inspired me to go into the same field.

Having struggled with primary hypothyroidism for sixty-plus years, I thought I knew everything about my condition. It was a surprise to learn of the cardiac potentiality. I'm short - in a tall family, now fat - in a trim bunch, and was recently diagnosed with high cholesterol and congestive heart failure, even though my diet isn't a problem. No one has ever suggested to me that all these could be related to my thyroid being dysfunctional since childhood. Sometimes, having specialists for doctors keeps one from getting the whole picture.

[@osian4182]

Great video and something pretty relevant to myself. I was born without a thyroid gland, so I don't really have all that great of an understanding of what a normal baseline would be regarding the potential symptoms either way. There were issues at the beginning of my life where my levels were showing below the healthy range, which transpired to be a result of baby formula containing soya. At the time, the hospital blamed my parents as they weren't aware of that fact and dismissed my parents when bringing it to their attention. In the end, I spent a fair few years going to another city's hospital that apparently approached the case in a more open-minded approach. Here I am at 25yo and surprisingly not having issues with weight control at least, other issues maybe not so lucky 😄 Sitting at 250 micrograms of thyroxine, which is probably a scarily large dose to some aha. Still manage to be a fairly capable cyclist and runner while also mixing in the gym. Do get knocked down a fair bit by motivation slumps due to some mental health struggles, which are likely not helped by a pure reliance on synthetic thyroxine, but I still find my groove after those blips (on a four week one now after my first covid infection and then a common cold right after, great timing 🙃) Thanks for all you do with these wonderfully informative dives into what makes us us.

Thank you for this awesome video. Your videos are so simple yet detailed. It helps me a lot with my therapy. I'm a visualization therapist, where I guide people to heal through visualization. The therapy works when one has a problematic organ/situation and then they must focus on the possible solution. Eg.: For a thyroid problem, talk to the pituitary gland and/or the thyroid gland to regulate matters. Of course, the therapy involves focus, meditative state along with internal dialogue with your organs. The best thing is if the solution is not that, it doesn't work. LOL! :) It doesn't mean the therapy is faulty, it means the problem is somewhere else.
