While it is not clear what causes gestational diabetes, some pregnant women develop insulin resistance, which means that the cells in their body do not respond to insulin normally. Every cell in our body uses glucose (sugar) for producing the energy needed for the cells to do their jobs. The glucose is derived from the foods you eat, primarily from carbohydrates. Insulin, a hormone produced by the pancreas, is the main chemical messenger that tells the cells that it is time to take up glucose. Insulin is also involved in messaging the liver to take up glucose and transform it into the storage form of glucose known as glycogen.  Insulin is also involved in a wide range of other functions like protein and fat metabolism. If the cells become insulin resistant, they ignore or can’t respond to the signal from insulin. This can increase the levels of glucose in the blood. When this happens, the pancreas responds by producing even more insulin.  The problem is that since the insulin has no effect on the insulin-resistant cells, the blood glucose levels can keep rising.  The body’s response is to convert the high levels of glucose in the blood into fat, and that can set up a scenario of chronic inflammation and other disorders like full blown Type 2 diabetes, metabolic syndrome and heart disease. During pregnancy, if insulin resistance is not properly controlled, you can develop gestational diabetes. It can have a number of effects on your and your baby's body. The main effect on the baby of uncontrolled gestational diabetes is increased fat in the blood stream, which leads to increased birth weight.  These babies are also at higher risk for difficult deliveries due to the size, breathing problems, obesity, lower than normal blood sugars and, as adults, Type 2 diabetes. The mom is at higher risk for cesarean section, Type 2 diabetes after pregnancy, and high blood pressure before and after delivery. Often, there are no symptoms of gestational diabetes, which most often begins about halfway through the pregnancy. This...
