Insufficient insulin secretion during pregnancy can be treated with dietary control as well as insulin injections. Insufficient insulin secretion may lead to abnormal blood sugar, i.e. diabetes. A good diet and lack of exercise during pregnancy is likely to cause fat accumulation leading to insufficient insulin secretion, which can be treated with dietary control and increased exercise by controlling the intake of foods high in carbohydrates, such as rice and noodles, and exercising appropriately.
