I was getting dizzy looking at my text book and this video felt like a light bulb going off in my head. You are amazing thank you!!
I was praying for months specifically for “enzyme” for my MCAT studying and then God answers my prayer! Your channel is so so helpful!! Thank you so much!!
Wow! This is one of the best videos I’ve seen regarding low/high calcium levels. Thank you!!
Mine some reason is low calcium which is odd cause I eat cheese and ICE cream 🍨 cheese 🧀
@@unknownwolf4046 Calcium Depletes Calcium from your Bones Stop eating Icecream and Dairy Products, cheese, yoghurts, things Like Cooking Oil Pepsi Drinks even Orange Juice Cereals anything Ulra Processed foods Ready Meals etc Coffee, Alcohol Tea. Artificial sweeteners, Corn Syrups, Sugar, Salt I have Really Low Calcium not have any of them 4 Glands have to be very low found out when mine was doubled by mistake and went to high then hyperparathoidism. Mine is diet controlled now thankfully
Perfect explanation and was very easy to understand, thank you sir!
Underrated video.. thank you so much
You're very welcome!
Thank you, I need to pass the Nutrition midterm and this helps.
You're very welcome!
THIS WAS SO HELPFUL!!! THANK YOU!
So clear, to the point and simple. Thank you
thanks so much. Finally I found a video that helped me understand low/ high calcium levels🙏🏼
Thank you for the explanation! I was able to easily understand this concept after viewing it.
Thank you, and glad this helped!
Excellent!!! I was having trouble understanding my A&P PowerPoint slides for my Lecture exam and now it makes perfect sense!! I wish my professor explained the way you do. Many thanks 😊😊😊
Thank you so much. Your explanation was crystal clear and very engaging. I wish I had you as my Anatomy professor!
Incredibly helpful video!!!!!!
Omg thank you so much u helped me to understand this so so easily else I would never understand this !!!
I am very grateful❤
Really helpful
Big thank you for explaining it well. My husband has very high Calcitonin levels for the last 25 years(he may be aware only then) - i keep reading about any materials on Calcitonin
You are brilliant 🤍 thanks for the clear and simple explanation ✨
Amazing video. The best I have found on this topic. Thank you so so so much, you made a very tedious topic so much easier!!!
Hi it’s a great video but you didn’t mention how PTH causes bone resorption. So here it is. PTH acts on osteoblasts which increases expression of RankL. This RankL causes differentiation of osteoblasts in to osteoclasts which causes bone resorption. Hence PTH causes oesteoclastic activity (maturation of osteoclasts) & osteoclastic osteolysis (bone resorption)
This was very helpful. Thank you!!
I'm using this video to introduce myself to these hormones for a school project. Thank you!
great video sir, this was a thorough yet concise explanation.
I really really really enjoyed that video. Thanks lol
Nice explanation! Thank you.
Thank you very much ❤️🔥🫶🏾
thank you! it was super clear and easy to follow
outstanding video ...thank you so much!
Thank you so much!!!!
This was so helpful.
Great explanation!
calcitriol is used by intestinal cells to synthesize proteins that actively carry (absorb) calcium, this process is called active calcium absorption, enabled by vitamin d but not forcing it.
There is a high percent of calcium absorption not dependent on active absorption, active absorption is critical though as part of the regulatory system of ionized/phos regulation in serum, but not solely dependent on it.
Thanks sir.
Amazing, Thank you very much
Very helpful!
Great video!!!!
perfect explanation
Thank you that's really helpful ❤❤❤
very helpful ! thank you.
You're welcome!
Amazing as always
Thank you 🙏
Good video
thank you thank you thank you
Thank you very much!
thank you very much
EXCELLENT .... VERY SIMPLE .... VERY NICE INFORMATION
this is a very good video sir !! thank you !!
Ty good video
Thanks
great content
Nice, thanks from Paris
This is so lucrative for me tnx you😇
Thanks doc
need such videos on topics of biochemistry
well done
Thank you!!!!!
thankyou so much it helps a lot!
Amazing
Great video! But what do I do ? My calcium is high .
THANK U SO MUCHH ILY
Excellent
What medicine or hormone will bring down calcium level to normal
I have had high calcium levels for years. I had a ultrasound and ct scan last year and it was find that my PTH levels were high. I was diagnosed with primary hyperparathyroidism. Also, deficient in Vitamin D levels. I’m currently taking Sensipar and 1000 IU of Vitamin D. What are your thoughts?
Hv u get rid from this problem?
Try 6-9mg/day of boron to support the parathyroids & 200+mcg of Vit K2-mk7. Also Iodol (Lugol's Oil) - Iodine needed to support the Thyroid.
Does vitamin k2 have a role in the calcium utilization in the nerves? Any role with parathyroid glands? Vitamin k2 carboxylates matrix GLA protien preventing calcification of arteries & carboxylates osteocalcin so it can deposit calcium into the bones. What are the other roles of vitamin k2 in calcium metabolism?
Great "add" with the role of K2! Another factor is adequate boron for proper parathyroid reg of mag. & cal. Also adequate iodine for C cell reg.
Osteoblast doesnt have calcitonin receptors. Calcitonin receptos are present in osteoclasts cells. However, since bone resorption and bone formation are coupled processes, eventually calcitonin's inhibition of osteoclastic activity leads to increased osteoblastic activity.
Explain in simpler words
What if you have no parafolicular cells? Thyroidectomy.
this is great!!!
Omg thanks king😭😭😭😭
But what about when osteoclasts/osteoblasts go haywire such as in DISH.
So blood level of calcium is much more used for. Cellular process like nerve more rather than strengthening bone mineral
This is the opposite advice my consultant gave me. He said high levels of calcium in blood causes osteoporosis as well as heart problems, fatigue and other serious symptoms.
I believe the conflict you see revolves around the distinction between total serum Ca levels and the proportions therein that include both Ca ions and bound-Ca. Health problems evolve with excess protein-bound Ca (essentially excess calcifications of the body's SOFT tissues). Ca leaching from bone/teeth is often driven by too LOW of pH (HIGH acidity) in tissues, as Ca alkalizes that excess acidity. The body proper pH tissue levels are partially regulated from adequate Vit D, Magnesium Iodine, Boron, & Vit. K2 for the proper balancing of Ca. imho - cheers
Love you
lack of vitamin d is causing a lot of people to get worse covid 19 can not absorb it dark skin type overweight where you live like places New York not enough sunlight vitamin d is vital to lmmune system
Cod liver oil or at least lanolin D3 gel caps, or UV lamps - if there's a will, there's a way! Cheers
❤
I have never had any calcium and have no osteoporosis i have hypoparathyroidism normally caused by radiation treatment for throat cancer just limit bad food and bad drinks like coffee and milk that deplete calcium from your bones things high in calcium like spinach kale carbonated drinks in a can protein drinks cooking oil, trans fats, processed foods microwave meals are bad i can not eat BBQ food or Party Food, please learn more about diet does to our bone loss it is not what people think like wear and tear it is what you eat and drink i had mine removed by mistake by the surgeon ended up making me autoimmune RA etc chronic fatigue brain fog etc thankfully im ok now it is now my normal way of life
👍👍👍👍👍👍👍👍👍👍
My calcium was slightly high
Normally your vedios are very acturate but not this time. You mentioned vitimin D but u overlooked K2 vitimin. Think you should remake this vedio and included it.. Without K2 big trouble in calcium
Mechanism
Also need boron for the parathy glands & iodine for the thy (tied to C-cell pathway)
Good thing I taken biology class in high school
thank you so much
thank you so much
