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.
Dizziness and lightheadedness are also early symptoms of pregnancy, caused by low blood pressure. In your first trimester, it is normal to experience dizziness during pregnancy as the blood vessels dilate, which reduces blood pressure. The blood pressure gets back to normal during the second trimester.
