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.
Many hormone levels are affected in the body during pregnancy, with several hormones playing major roles during pregnancy. These include: Human chorionic gonadotropin hormone (hCG). This hormone is only made during pregnancy â almost exclusively in the placenta. HCG hormone levels found in maternal blood and urine increase dramatically during the first trimester. They may contribute to causing nausea and vomiting often associated with pregnancy. Human placental lactogen (hPL). This hormone, also known as human chorionic somatomammotropin, is made by the placenta.
