Thyroid Hormones and Thyroid Function Tests

[@cypress2020]

The clearest and clinically most relevant thyroid video I've seen on KZbin.

[@kalldagreat]

Please keep on making these videos, you have no idea how much it has helped people from around the world!! I just want to express my deep gratitude to your unconditioned contribution!! Eric's Medical Lectures

[@StrongMed]

Kallmann Choong Thanks! I certainly plan on continuing to make videos for as long as I can carve out the time.

[@huyanhbui7105]

This was great, I been tryin to find out about "signs that your thyroid is not working properly" for a while now, and I think this has helped. Have you ever come across - Yannabarn Vanish Thyroid - (search on google ) ? Ive heard some awesome things about it and my work buddy got amazing results with it.

[@thomaslau9631]

The best presentation on the clinical aspect of Thyroid gland problem I come across so far. Thanks.

[@damnyeahnich]

Amazing! you've saved me hours of reading and understanding on my own! Thank you!!!

[@kalravjoshi3427]

BIG THANKS SIR. I AM A GENERAL PRACTITIONER IN INDIA. THIS SUBJECT IS ALWAYS CONFUSING AS TO UNDERSTAND FORM MEDICINE BOOKS LIKE HARRISON OR DAVIDSON. THIS VIDEO HAS CLEARED ALL MY CONCEPT NOW I CAN UNDERSTAND AND TREAT PATIENT VERY CAREFULLY AND PERFECTLY.

[@sunving]

Thank you very much Doctor Strong! You do a great contribution to many medical students,interns,residents, junior or not so junior doctors around the world.

[@irfankhan-rk2yd]

13:20 , you had me here, where you said "differentiated" thyroid cancers... attention to detail is just amazing.. reason behind it is the fact that, if you follow-up a patient with undifferentiated malignancy, thyroglobulin will not be increased.

NEVER HAVE I SEEN A VIDEO THIS CLAER, THANK YOU SO MUCH DOCTOR, AM A CUBAN TRAINED SOUTH AFRICAN STUDENT AND THIS HAS HELPED ME ALOOOOOT. YOU DESERVE MY SUBSCRIPTION...GRACIAS. STANFORD MLAMLI TIBE

[@MikeBirkhead]

Subtle (probably unimportant) correction: Wolf-Chaikoff effect refers only to the decreased activity of TPO in by iodide states. Several theories exist on why this occurs. From my short glance at the literature, my understanding is as follows There are three effects (including wolf-chaikoff) that make high iodide useful in hyperthyroidism. 1. It can inhibit TSH signaling (most likely via inhibiting the GPCR) 2. It can saturate the sodium iodide symporter (which is mechanism of protection from radioactive iodide). 3. Wolf-chaikoff effect -- inhibition of TPO activity (possibly by reducing peroxide levels -- perhaps through inhibition of NADPH-oxidase) It's also important to know that all three effects that work together to reduce thyroid hormone levels are subject to "escape" by a healthy thyroid after about 10 days. This is due to downregulation of the sodium iodide symporter, which reduces total intrafollucular iodide, thereby releasing from iodide inhibition.

I really wish to see more n more of such crisp, correct n precise info..thank you so much for posting such a productive content

[@mbulawandala8848]

I nearly got discouraged, but going through comments section, I then realized I'm not the only one who noticed- cold stimulates TRH release, and so does stress(emotional and physiological)

[@naveenbabu4057]

[@cocokrisp8967]

I really liked this video! Very clear voice and explanation. So helpful! Thanks!!

[@petercourt]

Very thorough and complete. Many thanks.

[@dr.md.shalahuddin2185]

Dear doctor Eric Strong. I am a medical graduate from Bangladesh. I must admit that your videos helped me immensely. Undoubtedly they are of high quality. But I have some questions. I will be highly grateful if I got the answer: 1. What is the mechanism that ESS causes so many patterns? 2. Would you please tell me which drug causes what change & how? I know if you answered those questions in the video, it would be a long one as well as boring. But I think it isn't so here.

[@thyroidhealing2118]

Love your video! I have started following a diet for 90 days which will completely cure Hypothyroidism if I follow it the right way. It may take longer than 90 days dependant upon how severe my condition is. I am on thyroid meds for 13 years now and I can't wait to take them off any live my life freely with full of energy and zeal!

[@Irene-ji8gh]

Thank you. Exxellent video. Dear Dr. I am Dr. Cekmen.M. from Turkey I am MD and PhD. At the about 9. minute of presentation, You said that ''cold stress can effect negative (-) on the TRH and TSH''. I know that ''cold and emotional stresses stimulates the synthesis or releases TRH and TSH''. Is it possible re-evaluation Please.

Kidney Fuctions Tests please Dr.Eric.

[@TheSurgeonsRoadie]

I noticed a slight jab there about rT3. If you have a surplus of rT3 after ruling out other pathologies, wouldn't you have a conversion or diodinase inefficiency? If you have a patient on Levothyroxine that's symptomatic it would warrant T3 supplementation. You could check the FT3 sure. As a provider, I'd check the rT3 also so I felt comfortable safely administering T3.

[@RooseveltPadilha]

Please keep on making videos! This was wonderful for me. Thx u a lot! :D

My dr gave me levothyroxine when I complained about being tired and stressed. With no blood test. Then he died. I’ve had minimal blood test sense but I’ve been on the drug for maybe four to six years. Is there any way for me to get off these drugs? I read somewhere that after you take this medicine your thyroid will never work again I hope that’s not the case. any ideas that could help me. I love your channel you’re great

[@mahamadtaqisundrani6291]

Sir,... We don't have Radioactive Iodine Thyroid Scan to be performed in all Cases of Thyrotoxicosis in our Small City. Whats the Best Practical Approach for us in Patients with High T4 and low TSH? Can We Differentiate Clinically between Graves and Thyroiditis? What will Happen if We prescribe Carbimazole to each and every Patients of High FT4 and Low TSH?

[@loochiano89]

good job

[@faraz1231]

Why only ft4 in hypo and both in hyper? Whats the difference between ft3 or ft4?. Why cant we only check one or the other?

[@adriyamuneer264]

how about thyroid cancers and nodule tests?

[@judypeng4748]

I had a Pt didn’t take his Levothyroxine for a week, the PMH only has HTN and DM. I guess he also has hypothyroidism because his home meds. He was present in ER with hypotension and anemia. He has sepsis but WBC only 4.5, next day became 3. Hgb 4.6, is possible because he didn’t take thyroid hormone that cause all blood components low, WBC low cause low immunity? Bacteremia cause septic shock?

[@LeonNikkidude]

I am Hyperthyroid patient that seems to need Methimazole like food!In 2017 when I reached 3.3 TSH (I was diagnosed in 2008 at 37) I stopped the Methimazole for 3 month and my TSH completely crashed!🚨What are best tips for me besides Brazil nuts , avoiding gluten which is impossible for me and yes I do limit sugar as well!My recent T4 was 12.2 close to range and I figure I have to get to around 5 but what else should I do!?

thank u so much for such good explanation............can u pls do a lecture on liver cirrhosis pathophysiology including NASH induced one and LFT interpretation..............thank u .........

Is there a KFTs video ?

[@matthewxavier2625]

Dear Doctor, I am a medical student from Guyana. I was reading online, and noticed that patients with Secondary/Central Hypothyroidsm can also have, contrary to my understanding, normal TSH levels; I assumed that with pituitary dysfunction, you would have low TSH levels, hence the low thyroid levels. This obviously confuses me, so I'm wondering if you could share some light on whether this is actually possible and if so, how? Since we do have a patient with normal TSH levels, normal FT3 but low FT4 on the wards, and I would like to know what could be the possible etiologies/classification. However, you only have here in your video that patients with normal TSH levels and hyper/hypo thyroid hormone levels can either be classified also as having euthyroid sick syndrome or from some drug's effect, but no mention of a possible secondary cause, so I'm just wondering. Thank You

[@katherinemirasol852]

My TSH is high and my FT4 is normal, the doctor asked me to have T3 test. what will be to expect in the t3 test & what does it mean of whatever result may?

hello there Dr strong i hope you are well. I have a question about endocrinology but it's not related to thyroid. what is the physiologic actions of prolactin and oxytocin in men? it seems to me that their only benefit is in women, in men they get released in some diseases and just cause problems. i have looked in some physiology books but they don't mention anything about them in men. thank you very much
