Final Exam Objectives


DIABETES

Hormone Function Mechanism
Insulin (beta cells)

(released after a meal)

Sugar control

Protein and lipid metabolism

Growth and development

Lowers blood sugar

Facilitates transport of sugar inside cells.

Insulin promotes lipid and protein storage and synthesis

Glucagon (alpha cells)

(released during fast)

Regulate blood sugar Breakdown of sugar
Somatotropin (delta cells) Regulation of GI absorption  

Diabetes Mellitus

Type I Type II
Insulin dependant

10% of diabetes is this kind

Patient cannot synthesize insulin

Usually from childhood

Insulin required for treatment

Non insulin dependant

90% of diabetes is this kind

Tissue fails to respond to insulin

Usually in adults (obesity main contributor)

 

Complications in Diabetes

Short term hyperglycemia: results in increased  glucose excretion (kidney is unable to absorb glucose).  This causes shift in energy source to proteins and fat which leads to formation of acidic ketones and lower pH levels in the body = ketoacidosis.  This can lead to coma or even death.

Long term: thickening of small vessels eg in the retina leading to blindness and in kidney to  renal failure. 

Therapy

Hypoglycemia

Eg Dymelor, Glucamide, Glucotrol etc.  These drugs help to decrease level of sugar in blood (not effective for Type I, as these drugs only facilitate insulin in its function)

Adverse effects: hypoglycemia, GI stress, heartburn, headache, confusion etc.

Glucagon: promotes sugar release, usually given by IV.

Cyclosporine: used to prevent tissue rejection during organ transplant.  It decreases need to insulin in Type I diabetes.

Diabetes

Type I.  Insulin injections. 

Type II: non drug therapy: improvement in diet, weight control and exercise.  Islet cell replacement therapy (surgical process)
