Diabetes 2, Blood Glucose Homeostasis
Vložit
- čas přidán 17. 06. 2013
- It is essential that blood glucose concentrations are maintained at relatively constant levels. Glucose is the only form of sugar found in the blood. If other sugars, such as fructose or galactose, are absorbed from the gut, the liver quickly converts them into glucose. If there is too much glucose in the blood this will damage several body tissues, however if there is not enough, cells will not be able to use glucose as a fuel in the mitochondria. High blood glucose levels are referred to as hyperglycaemia and low levels as hypoglycaemia.

My oldest son is in his early 20's and he has type 1 diabetes. But thank God for this piece of article czcams.com/users/postUgkxVYhghKWmrUgXARZ_ydZTvmmcrw5L0I5i At first he thought he had the flu and was lying down on the bed for three days until his sister took him to the hospital. They took his blood and it was 600. What I do not understand is how he could have gotten it, since no one in the family has it. But he is winning the battle now. This is good stuff.
Excellent tutorial. Clear and concise explanation with nothing taken for granted .
Wish now that I had chosen Medicine instead of Architecture , I might have a better understanding of the causes of all my conditions and know how best to assist my body back to health.
Thank you Dr Campbell
wow! what a clear and concise video for me as a nursing student in University of Ghana. thank you so much doctor.
Doctor John thank you very much ! you can't imagine the benefit in this lecture
Thank you for what you do! May God continue to bless you. You are so articulate, clear and pleasant to watch...Thank you!
Thanks Dr. John.1st time i have cleared the basic concept of Homeostasis of blood sugar at cellular level. U are the best teacher,i think in the world. Again thanks a lot sir for sharing ur lectures.
Awesome explanation sir. Thank you very much.
You're a life savior. Thank you so damn much.
Dear Dr John Dampbell,
Thank you for your huge contributes, what an amazing video!
I don't know How I am going to keep continue to stay on my course without your explanations, no doubt You are the best teacher ever!
and I am your big fan now, hope one day I will become just like you to help others.
Nice video, I use Libre and Blucon and love them to control my blood glucose values. The alarms are nice and are loud enough to wake me up. You can adjust your BG ranges to whatever you want. The best part of blucon is I can calibrate it for higher accuracy!
I’m watching them all out of interest, behind a diabetic , good refresher. Thank-you for making them available. .
very useful video for 2nd year medical school at UCL - thanks
I appreciate you! Thank you for sharing what you've learned in these videos. I was diagnosed with adult onset diabetes mellitus type 1 when I was 15 years old. You've explained a lot of stuff that I didn't know. I hope I can get the people who say they care about me to watch your videos.
Thank you very much Im so happy I found your lecture. It was direct, clear and incredibly well explained.

thank you for posting these amazing videos, really helpful
thank you very much sir for your video. The way you explain is so clear and easy to understand compared to other videos. Im studying with your videos alone help with my uni assignments
Love your videos please make more.
You are a hero ! Thank you doctor
i think u#you are amazing John.first started watching you at the beginning of covid. then followed you at the beginning of my 1st yr student nursing. thank you so much :)
Thank you so, so, so much! You make learning MUCH more interesting. Though this isn't a necessary topic to learn for my current grade in school, your videos always make me want to learn and understand things beyond my online classes. Learning from a great teacher like you is something I will always thank you for ^^ I hope you are doing well.
Indeed u are the best teacher in the world i have ever seen ,thnks dr
Thanks for the video, I have been suffering from diabetes for the last two years and have been using Libre . A few months ago I read about the Ambrosia Blucon device on Facebook and its premium app features and purchased the device through their website. Now I use Blucon and I able to check the BG values on my watch when I am at work and my phone is not near me.
Hi, one of my friend suggested me for Ambrosia device, now I am using it for last 6 months which always track me the glucose, insulin, exercise on one platform and I am able to extend the life of my sensor with the help of Blucon for another 14 days.
Outstanding explanation!
Nice video, I bought Ambrosia Nightrider cgm to monitor glucose which works great with the Libre sensor, their alarm feature is very helpful during night, it also gives alarm alerts when readings are not in range
Weldone dr.ts really agreat work,am understandng.
that was so interesting and so well explained ...thankyou
Thanks. Very simple for layman to understand
Listening to this chap explain metabolic processes is like listening to a technical version of Sargent pepper’s 🙂
Very good videos, thank you!
Great information on health education
Absolutely amazing!!
Honestly I love you. Half way you even ask questions which I love to. Thank you💙💙💙
Remarkable What clarity 😃
Thank you so much, Dr. Campbell. Your lecture is very clear. I am glad to know you with your excellent lectures
Absolutely amazing lecture ❤️
Inshulin? Beeta cells? Love this guy! :)
Thank you for another great video!
you are amazing .. thank you very very much
thanks Rahmah, which country are you in?
Dr john campbell you are an inspiration I love your lectures, I hope one-day I'll be able to translate your lectures into Pashto language so that million Afghan students at high school and universities will benefit from your work.
U are so great, Dr.... God bless u
The best work I ever seen
Dr John Campbell sir great feedback as always in your all videos god bless you and give you sound health 13/04/2022
Excellent!
It is pretty good lecture. Just a little thing (probably slip off the tongue) at 23:12 - should b glycogenolysis, bot -neolysis. But anyways, great stuff professor.
thanks for the awesome videos
Hi, just wanted to ask: as per my understanding the conversion of Glycogen to Glucose is called Glycogenolysis as opposed to Gluconeolysis as suggested in your video at 23'13.. I was under the impression gluconeolysis would mean 'splitting of new glucose' molecules... i should be grateful for the clarity and thanking you in anticipation for your great work and excellent lectures.

I’m so happy with this lecture 🥰🥰🥰🥰🥰🥰thank you Sir🥰🥰
The best teacher ever🥰🥰🥰🥰🥰🥰
Very nice Sir .Thanks alot .
Dr John I love you so much
Brilliant teaching
Very educative.
Thank you very much for this video! Very very helpful :)))
looking dapper mate
Bravo! thank you.
Ty sir grt job👏🏻👏🏻
Nice video, I am using Freestyle Libre Sensor with Ambrosia Blucon from last one month, it converts Libre sensor into a full CGM and I can able to see glucose readings every 5 minutes on phone and watch without scanning the Libre sensor. Now I don't need to scan the Libre sensor and gets reading every 5 minutes on my iPhone.
God bless you sir
No seriously, this guy is VERY helpful.
Thank you sir...
Thanks you Sir🙏
Thank you sir
what you explained also applies to transistors, you have the reseptor (gate) and the glut (base) and the glucose (emitter) think that's it
Thank you much !!!!!!
Bravo
thank you dr. :)
Great explanation
Thank you
how can i download this all video
Why do people get hypoglycemia if the alpha cells produce glucagon
dr campbell how does the insulin makes glucose into glycogen ? does it combine with the glucose and becomes glycogen?
This is good
Who the hell was the guy that figured all this out?
Great question, Banting and Best (1922) are famous for discovering insulin, there have also been progressive discoveries over the decades, much of the early dissection work was carried out by John Hunter who died in 1793.
thnx man
being recommended to doctor Igudia on CZcams has being a great blessing to my family his cure for type 2 diabetes’s is a genuine one thanks for your good deed toward humanity.
Thanksssss
Well I was looking more for a ballpark figure
@ Matt... that is British pronunciation of insulin. Just like the Americans pronounce 'Blessh' instead of Bless
so is gluttony described as having a sweet tooth ;)
are the insulin receptors at fixed points in the cells or do they move about
Insulin receptor (IR) is a chemotactic receptor capable of driving T cell movement in response to insulin. Insulin receptors don't move they are present on cell membrane but the GLUT receptors do...Hope this satisfied u..

No such thing as essential carbs.
