Q

source of glucose in brain during fast

A

protien

22
Q

primary energy resivoir

A

fat

23
Q

first energy source

A

glucose

24
Q

diabetes insipidus cause

A

ADH deficiency

25
Q

insulin absense- what does this cause

A

in type 1, glucagon glucose sensing fails so more glucose in blood

for treatment need insuliin and somatostatin

26

A

5%

27
Q

AIC for diabetic

A

6.5-7%

target two hour glucose for diabetic

A

5-10

30
Q

normal fasting blood glucose range

A

less than 6

31
Q

what diabetes with metabolic disease

A

type 2

32
Q

what is the sensor for insulin release

A

beta cells

33
Q

TZDS fucntion

A

insulin sensitizing drugs for type 2
improved AIC and glucose control

34
Q

TZDS fucntion

A

insulin sensitizing drugs for type 2
improved AIC and glucose controlm

35
Q

mechanism of action for TZDS

A

inc fat storage reducing circulating FA, blood glucose and hyperinsulemai

36
Q

health risk of TZDS

A

bone density
cancer
CVD
