raises blood glucose during rest

Question 12

why is the degradation of fat necessary during gluconeogenesis?

Answer 12

gluconeogenesis is expensive and fats contain alot of energy.

Question 13

explain the metabolism in uncontrolled DM

Answer 13

1. condition
   
   1. insulin insufficieny
2. macrnutrients
   
   1. glucose
      
      1. w/o insulin cells are starved for glucose
      2. causing
         
         1. release of glucagon
            
            1. gluconeogenesis
            2. ​lipolysis
         2. more glucose in the bloodstream
   2. fat
      
      1. w/o insulin LPL synthesis decreases
         
         1. insulin stimulates the synthesis of LPL,
         2. result in
            
            1. uptake of fatty acids
            2. accumulation of
               
               1. _​chylomicrons_
               2. VLDLs
      2. triglyceride breakdown INCREASES
         
         1. intermediate fats are broken down into ketones, and accumulate in the blood stream.
            
            1. leads to ketoacidosis (T1DM)
   3. protein
      
      1. w/o insulin proteins are broken down to secure energy
         
         1. loss of protein leads to weight loss, muscle waisting, urinary nitrogen loss

Question 14

how is heart disease related to diabetes?

Answer 14

insulin is necesarry for the synthesis of LPL.

With the decrease in insulin circulation, the patient experiences an accumulation of chylomicrons** and **VLDL

Question 15

describe the clinical feature of dylipidemia

Answer 15

elevated triglycerides

decreased HDL cholesterol

Question 16

what is hypertension considered?

Answer 16

a comorbid condition, two conditions at once.

Question 17

long term complications of diabetes lead two -emia’s and damage to what organ?

Answer 17

1. hyperglycemia
2. hyperlipidemia

these both cause microvascular and macrovascular trauma. Acut pancreatitis is the result from damage to acinar cells and microvasculature. this condition is compounded by the release of pancreatic enzymes in the enviornment. with a decrease in pH, due to CO increase, the trypsinogen is converted to active form trypsin and causes more damage.

Question 18

what is the general management of diabetes

Answer 18

1. early detection
2. prevention of complications
3. glucose tolerance test
4. goals
   
   1. mantaining optimal nutrition
   2. avoiding symptoms
   3. preventing comlications
5. self care skills
   
   1. basic elements
   2. healthy diet
   3. physical activity
      
      1. generates GLUT4 channlels in muscle w/o insulin
   4. adequate dosage and timely intake of hypoglycemic agents (only T2DM)
   5. titrate insulin dosage

Question 19

describe the order of macronutrients in order for diabetic persons

Answer 19

1. carbohydrates
2. proteins
