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.
Remember that the extra weight and your growing belly can affect your balance and may cause falls. In the earlier stages of your pregnancy, nausea and dizziness can also increase your chance of injury, especially if your job is very strenuous. The jury is still out on how much physical exertion at work is safe during pregnancy.
