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.
Similarly, estrogen, another hormone that increases during pregnancy, is associated with an increased frequency of nausea and vomiting during pregnancy. It's possible that nausea and vomiting during pregnancy might indicate that you're experiencing the normal climb in pregnancy hormones needed for a healthy pregnancy. However, high pregnancy hormone levels aren't consistently associated with nausea and vomiting. Keep in mind that a lack of nausea and vomiting during pregnancy isn't cause for concern. Some women with healthy pregnancies never experience morning sickness.
