Diabetes 2, Blood Glucose Homeostasis

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 kzbin.infoUgkxVYhghKWmrUgXARZ_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.

[@johncooper7242]

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

[@collinsaddo3982]

wow! what a clear and concise video for me as a nursing student in University of Ghana. thank you so much doctor.

[@drameer8631]

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.

[@saacidsamakaab9997]

Doctor John thank you very much ! you can't imagine the benefit in this lecture

[@cherylsmith6588]

Thank you for what you do! May God continue to bless you. You are so articulate, clear and pleasant to watch...Thank you!

[@kenyu5216]

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.

[@AngelaAllumu]

You're a life savior. Thank you so damn much.

[@amberally]

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.

[@TindallAndrew]

very useful video for 2nd year medical school at UCL - thanks

[@shreyarastogi7303]

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!

[@briarparkinson5106]

I’m watching them all out of interest, behind a diabetic , good refresher. Thank-you for making them available. .

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 :)

[@cheshire__kat]

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.

[@YO-DASISTMICH]

Outstanding explanation!

[@julliethomas8191]

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.

[@shreyarastogi7303]

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.

[@gulikaay9485]

Listening to this chap explain metabolic processes is like listening to a technical version of Sargent pepper’s 🙂

[@lisaandrew4421]

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

[@martinsinclair55]

Thanks. Very simple for layman to understand

[@piotrdominek9613]

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.

[@fimasobak2520]

Excellent!

Dr John Campbell sir great feedback as always in your all videos god bless you and give you sound health 13/04/2022

[@gogreenmodern]

looking dapper mate

[@MedicAbbas]

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.

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.

[@jonabelcabrera4785]

dr campbell how does the insulin makes glucose into glycogen ? does it combine with the glucose and becomes glycogen?

[@enzoguerra6960]

what you explained also applies to transistors, you have the reseptor (gate) and the glut (base) and the glucose (emitter) think that's it

[@oguzieonyeyirim847]

[@estebancorral5151]

are the insulin receptors at fixed points in the cells or do they move about

[@razaakhtar38]

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..

[@martinsinclair55]

Who the hell was the guy that figured all this out?

[@Campbellteaching]

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.

@ Matt... that is British pronunciation of insulin. Just like the Americans pronounce 'Blessh' instead of Bless
