Question | Answer |
What is considered a key to optimal pregnancy outcome? | strict maternal glucose control before conception and thru preg |
what is DM | hyperglycemia resulting in deficient insulin secretion/action/both |
Where is insulin produced | B-cells in islets of Langerhans of pancreas |
what does insulin do | reg blood glucose lvls by allowing glucose to enter adipose/muscle cells. It's used for energy. Stimulates protein synthesis. Stores free fatty acids |
what is meant by hyperglycemia causes hyperosmolarity of the blood? | intracellular fluid moves into vascular system, resulting in cellular dehydration and expanded blood volume, |
