[@dociyyer]

This is the simplest way of explaining the concepts of DKA.I loved it Dr John.Thanks a lot

[@AnnaAnna-ch5ww]

Dear Dr Campbell. Every evening, after all my chores are done, I watch your lectures. Your explanations are always the best, they supplement my nursing textbook reading so well. Thank you very much!

[@fangzhenxiang5136]

me too

[@LarrehStylinson]

Thank you. I have an important exam in a few days and your explaining makes me feel alot more calmer.

[@lateo100]

Thank you , simplified and put together all the bits I needed. Thank you again and you are for a good cause sending funds to less advantaged people. Thanks again.

[@mcangie1]

I am a new nursing grad about to take my RN nclex and I wish I would have found you years earlier. I love the way you teach and explain things. It really makes sense and I thank you for posting your lectures and lessons. I will continue to use your lessons throughout my nursing career and will highly recommend you.

[@Campbellteaching]

Thanks Mcangie, best wishes for the NCLEX.

[@manjitdhami]

I am a big fan of your presentations - really really appreciate the amount I have learnt from you - but I have a few questions about the flow - my understanding is - insulin will shut off movement of glucose in the muscles and fat cells - muscles will then have no choice but to switch to glycolysis (relying on small glycogen stores it has) and/or fat utilisation as energy source (which is a slow process) - this causes ketone bodies to form in the blood and in extreme cases DKA, liver has no problem getting glucose in cause it has two-way insulin independent GLUT-2 pump, brain is fine too cause it has just like RBC (GLUT-2) insulin-independent GLUT-1 but the glucose it is producing is not getting to the muscles and that is the problem. So I am entirely sure how liver is a contributing factor to formation of ketone bodies. Insulin shut off gluconeogenesis so really it is the glucose and hyperosmotic effects it will have and various other problems (glycated products etc) which is the issue. I would appreciate if somehow you find some time somehow to let me know what am I missing - thank you for all your excellent excellent presentations.

[@lucasglatthardt5368]

I'm not sure i quite understand your doubt here. But what i think is the key to the pathophisiological process is the complete (or near complete) absence of insulin, resulting in no negative feedback with the counterregulatory hormones (glucagon, cortisol, even cathecolamines). Because of the complete absence of the negative feedback, your body interpretates as if your in a state of fasting. Hope i helped you somehow !

[@lucasglatthardt5368]

That is why even though the liver and brain are being able to use glicosis just fine, the liver still induces glicogenolisis, gliconeogenesis and beta oxidation of the fatty acids. Because of the counterregulatory hormones effect on the liver, wich are very high in DKA.

[@lawrencefernham4884]

Good video, nice flow diagram haha! One thing I don't get is the K+ situation; I thought K+ was pumped into the blood in order to balance the high H+ being produced, so you were HYPERkalaemic? I'm obviously wrong, but could you maybe explain this part of it a little bit more? Thank you!

[@lucasglatthardt5368]

I share your thoughts. I guess it is really a relative thing. Some patients might develop hyper or hypokalemia depending on how much K+ is being lost in the urine and how much is going from the cells to the blood to trade that H+

[@lucasglatthardt5368]

Guess we'll only know for sure with arterial gasometria

[@majuthomas7090]

[@arshadali9901]

cha gya boss

[@johnthadiabetic4927]

I had diabetic ketoacidosis yesterday. Blood glucose: >33.3 mmol /l consistently all day, and i became very dehydrated. In addition to that i had a rapid pulse, acetone breath and felt quite cold. I went to the GP, he put me on a drip, the drip attached to the top of a lamp (he had to improvise) lol. I want to ask, when you say fatty acids and ketones are used by the cells, i notice my muscles felt "lactic" was that the ketones and fatty acids? Are ketones acidic in solution... ? Or does the cells metabolise them into acid? But ketones resist mild oxidation.... so it confuses me slightly.

[@zuckerfreihd]

I can remember my ketoacidosis like a Nightmare. I was so tired and thirsty. But if I drank some Water, I've spilled it out almost instandly.

[@ryanau7222]

i too remember that nightmare.

[@somaijoj8614]

wow think you so much it have important for no Diabetes 15, Diabetic Ketoacidosis in other country that there are some people have it. can lost it.

[@abo_asaad2159]

hi Dr... u really astonished doctor... why there is ketoacidosis in type 1 but no in type 2 as u say in another videos TKu so much. ..

[@Campbellteaching]

Because the ketosis is caused by insulin lack and in type 2 DM, there is still some insulin in the system. However, in type 1 DM, there is an absolute deficiency of insulin, leading to ketogenesis.

[@nellyhoffman6194]

Doctor you are amazing :)

[@oluwasomiji]

Hello Dr. Campbell, thanks for the video, it is very helpful. My question is about the treatment for DKA. A text I was reading stated that ..."if a patient is hypokalemic, insulin administration will further decrease the potassium level leading to life - threatening hypokalemia." In this case, what should be done -hold off for the insulin-?

[@Campbellteaching]

You are correct. Insulin gates both glucose and potassium into the cell cytosol from the tissue fluids and blood. Giving insulin will therefore lower glucose and potassium serum levels. It will therefore be usual to give insulin and potassium together, according to local protocols. This must of course be done very carefully, as rapid changes in potassium can lead to ventricular fibrillation.

[@anilkarameti484]

Acidosis causes vomiting very often, you didn't mention that doctor?

[@siejare]

in 7:58 you say hypoglycaemia, but you write down hyperglycaemic, low insulin levels cause hyperglycaemic as in diabetes

[@Joan26404]

woow.. thanks a lot

[@Giati270170]

i would like to say that at first metabolic acidosis causes HYPERKALEMIA bc due to the acidosis protons (H+) leak into the cells and Kallium out .But in continuity we will give potassium as treatment as a result of insulin substitution which will reduce the potassium in blood . So at first there is hyper or hypokalemia ?

[@camilia71]

at first there is hyperkalemia and once they recieve insulin they will have hypokalemia so they will recieve KCL

[@cosmosradio]

Does this have anything to do with how the body is affected by a Keto diet?

[@TheSaintemplar64]

John shouldn't we give titrated oxygen also to help with the acidosis, Kussmals breathing, the patient's gaseous exchange is not controlled due to hyperventilation. O2 will help correct the acidosis? I'm not 100% Thanks

[@Psychiatrist78]

Very nice video but 1 thing that always confuses me. what is the stimulus of glucagon? If a person has an insulin deficiency is it the intracellular glucose or the serum glucose which stimulates glucagon? cause if it's the serum glucose why on earth would glucagon be secreted when there is already a high glucose in the blood( if it's the intracellular then it may make sense ). Does insulin have a direct inhibitory effect on insulin or not? thnx for the answer in advance.

[@Campbellteaching]

+Georgios Spartan Low blood glucose levels are directly detected by the alpha cells, which then respond by secreting glucagon. Therefore the direct stimulus for glucagon secretion is relative hypoglycaemia. This mechanism works, independently of insulin. Stimulation for insulin secretion, from the beta cells, is raised level of glucose in the blood. In both cases, it is the levels of glucose in the blood plasma which is detected.

[@Psychiatrist78]

+Dr. John Campbell : thank you but you have partly answered my question. When you have an insulin deficiency or resistance in diabetes then the sugar in the blood is high--then why does is glucagon secreted? since you say the stimulus is relative hypoglycemia. Glucagon should not be secreted is sugar is high!! except if there is an another stimulus or for some reason glucagon regulation /secretion in diabetics malfunctions.

[@Campbellteaching]

+Georgios Spartan Yes, there is always an extra layer of complexity. Secretion of glucagon has a U shaped secretion pattern, as stimulated by glucose. So, low levels of serum glucose will stimulate glucagon secretion, this is well established. Then as plasma concentrations of glucose rise, the secretion of glucagon is inhibited by this rise. However, as glucose levels rise still further, into the pathological hyperglycaemic ranges, this hyperglycaemia, paradoxically, but for definite, stimulates glucagon secretion. Therefore glucagon secretion is stimulated by low, and very high plasma glucose concentrations. This is because the body needs to use ketones, when insulin lack prevents the use of glucose as a metabolic fuel substrate. So the very high levels of glucose are detected by the alpha cells as pathological, this is how the alpha cells 'know' the body is in need of ketones as an emergency substrate. The alpha cells will then release the glucagon to stimulate the required ketogenesis.

[@Psychiatrist78]

+Dr. John Campbell Brilliant!) Now i got you)) now its all clear) thnx a lot , i appreciate it)) have a nice day!)

[@cardozaPC]

Thanks Dr. Campbell, I had a question about the treatment if the patient has cerebral edema, in the use of manitol or hypertonic saline, which one has better outcome or it's better to use manitol and if the patient is not responding to treatment use the hypertonic saline?

[@Campbellteaching]

Pedro Cardoza I don't know, you ask a good question. In the words of Kamel H1, Navi BB, Nakagawa K, Hemphill JC 3rd, Ko NU writing in Hypertonic saline versus mannitol for the treatment of elevated intracranial pressure: a meta-analysis of randomized clinical trials. 'We found that hypertonic saline is more effective than mannitol for the treatment of elevated intracranial pressure. Our meta-analysis is limited by the small number and size of eligible trials, but our findings suggest that hypertonic saline may be superior to the current standard of care and argue for a large, multicenter, randomized trial to definitively establish the first-line medical therapy for intracranial hypertension.'

[@cardozaPC]

Thanks Dr. Campbell!

[@SajjadAli-nn1ql]

Pedro Cardoza I think monitol is better I have seen it used much

[@mahu2468]

Hi Dr Campbell. Does the resulting free fatty acids transferred into the blood result in an increased level of LDL and HDL lipids? if so does this result in an increased likelihood of thrombus formation and Cardiovascular pathology in patients with T1DM? Jordan,NZ Nursing Student

[@Campbellteaching]

Hello Jordan, Patients with DM 1 or DM 2 are prone to diabetic dyslipidaemia. There is a tendency for protective HDL to go down, while at the same time harmful, atherogenic LDL goes up. Triglycerides can also be raised. These dislipidemic factors will certainly predispose to deposition of atheroma in the process of atherosclerosis. If atheromatous plaques become unstable, thrombus formation will develop leading to stroke or MI.

[@abo_asaad2159]

+Dr. John Campbell how TAG will accumulate and lead to dyslipdemia if there is breaking down for the lipids in body and as a result from it weight loss. .... .. clear that to me...TKU so much

[@siejare]

so very low insulin levels (almost none) causes hypoglyceamia and very high levels causes hypoglyceamia, the 2nd one called hyperglycaemic hypoglyceamia

[@camilia71]

low insulin levels causes hyperglycemia

[@GOOCHxo]

Is it possible to have DKA with low blood sugar? Is this only possible after having high blood glucose and then injecting to lower blood sugar but still being in DKA?

[@Campbellteaching]

There will always be a degree of hyperglycaemia associated with DKA as both are causes by insulin lack.

[@scarred10]

Theres also euglycemic dka with some diabetic drugs,but I think the glucose is still a bit high.

[@suprajaadesing9447]

Does DKA occur in type 2 dm?

[@leannemichael2859]

My Boyfriend died he was a achoic and he was tiie 1 dibeatic he would drink alot do you think he died of the drink as well????

[@Campbellteaching]

Hello Leanne, Its hard to tell by what you have said here, but certainly drinking too much and poorly controlled diabetes are both risk factors. It may have been that the drinking interfered with his ability to care for his diabetes, so his levels of diabetic control were not as good as they could have been. If his levels of diabetic control were poor, this would make it more likely he would develop complications, such as heart disease. Whatever the precise cause of his death, I am sorry for your loss. John

[@leannemichael2859]

thanks we was told he died from KETOACIDOSIS

[@gat1986]

What is the cause for the vasodilation?

[@Campbellteaching]

+Graham Taylor I think its the acidosis. The acidosis interferes with the ably of the peripheral arterioles, and their neuronal innervations to function. Without neuronal innervation, peripheral vessels with dilate on their own.

[@gat1986]

+Dr. John Campbell Thanks Dr. Campbell, I have a nursing exam on Tuesday, your videos have been extremely useful as well as your books! Wish me luck!

[@Campbellteaching]

+Graham Taylor I do, train hard, fight easy.

[@Psychiatrist78]

+Graham Taylor Ketoacidosis causes an autonomic type of neuropathy(damage to nerves) including faulty regulation of innervation of blood vesels leading to vasodilation.

[@gat1986]
