a) Glycogen synthase
b) glycolysis in liver + muscle
c) gluconeogenesis

A

What does Insulin release do to:

a) Glycogen synthase —-> turns on
b) glycolysis in liver + muscle —-> turns on
c) gluconeogenesis —> switches off

Q

What does insulin do to:

a) keton production
b) fat generation
c) glucose uptake

A

insulin:
- suppresses ketone production
- stimulates fat generation
- stimulates glucose uptake from blood into tissue

Q

What happens if there is total absence of insulin?

what does the liver do?

A
  • when insulin = 0 liver produces large amounts of ketone
  • -> causes DKA

can cause death

14
Q

What happens in T2DM ?

A
  • you make insulin
  • but effect is weak
  • so only some glucose are let in via GLUT 4

-SO patients are: hyperglycemic –> without ketosis

Q

T2DM patients tend to be
younger / older
obese / thin
glucose rises rapidly/gradually causing polyuria + polydipsia

A

T2DM patients tend to be
older
obese
glucose rises gradually causing polyuria + polydipsia

17
Q

SEVERE T2DM can get :

A

–> can cause HONKC

hyper-osmolar non ketotic coma

18
Q

How would you manage HONKC ?

A
  • rehydrate with normal saline slowly
19
Q

How would you treat T2DM?

A
  • lose weight
  • avoid sugar
  • slow absorption of carbohydrates
  • medications (e.g metformin/ sulphonyl ure)
20
Q

What is the diagnosis?
FG = 7.4 mM
following GTT 2 hr value = 7.7

*FG = fasting glucose level

A

diagnosis: Type 2 diabetes

if FG > 7.0 then you are 100% diabetes

21
Q

With STRONG FAMILY HISTORY
- which is most likely

T1DM
or
T2DM

A

T2DM

22
Q

With the obese
- which is most likely

T1DM
or
T2DM

A

T2DM

23
Q

With the young
- which is most likely

T1DM
or
T2DM

A

T1DM

24
Q

Compare between T1DM + T2DM

A

T1DM

  • immune destruction of pancreas
  • insulin dependent diabetes
  • usually young
  • DKA
  • quite high glucose

T2DM

  • resistance to insulin action
  • non insulin dependent diabetes
  • Maturity Onset Diabetes
  • Often overweight
  • very high glucose
25
Q

6 Classes of drugs for diabetes

and in what order are they administrated

A
  1. Biguanide (Metformin)
  2. Sulphonylurea (Gliclazide, Glibenclamide)
  3. Thiozolidinediones (Pioglitazone)
  4. Incretins (GLP-1 analogues, exantide)
  5. Gliflozins (SGLT2 Inhibitors)
  6. Insulin
26
Q

What is better than metformin at preventing diabetes?

A

Diet + exercise
