Metabolic Actions of Insulin and Glucagon Fatty acid uptake and release in fat. Insulin Stimulates synthesis of triglycerides (TG) from free fatty acids (FFA); inhibits release of FFA from TG. Glucagon Stimulates release of FFA from TG.
What causes dizziness during pregnancy? The main cause of dizziness in pregnancy is due to the rising hormones that cause your blood vessels to relax and widen. This helps increase the blood flow to your baby, but it slows the return of the blood in the veins to you.
Fainting is rare but does happen even in some healthy pregnant women. There are many reasons for these symptoms. The growth of more blood vessels in early pregnancy, the pressure of the expanding uterus on blood vessels, and the body's increased need for food all can make a pregnant woman feel lightheaded and dizzy. What might help: Stand up slowly.
