Medical Nutrition Therapy for Gestational Diabetes Medical Nutrition Therapy (MNT) is the foundation of physician management of all types of diabetes and is an integral part of diabetes self-education that should continue through all phases of diabetes prevention. MNT elevates nutrition from a purely dietary dimension to a medical treatment that helps physicians manage the whole patient, saves money on health care, and helps improve clinical outcomes in diabetes, as nutrition and metabolism are the initiating links in diabetes. The goals of MNT in gestational diabetes are to ensure normal life of diabetic patients and normal growth and development of the fetus in utero, to correct existing metabolic disorders, to reduce the load on pancreatic beta cells, thus delaying the occurrence and development of diabetic complications, to improve the quality of life of patients, and to improve pregnancy outcomes, with the following specific goals. By balancing the patient’s diet, the doctor focuses on reasonable nutrition, controlling blood glucose and blood lipids, supplementing high-quality protein, and preventing the deficiency of other essential nutrients. 2.Reducing pancreatic β-cell load. Diabetic patients have different degrees of pancreatic islet dysfunction. A reasonable diet can reduce the pancreatic β-cell load and help restore some of the functions of the β-cells. 3.Prevent and control complications. Individualized MNT can provide appropriate and sufficient nutrients, which is conducive to the prevention and control of diabetic complications. 4.Improve patients’ quality of life and overall health. 5.For women during pregnancy or lactation, physicians should place special emphasis on meeting their nutritional needs during this specific period of pregnancy. MNT is recommended for patients with any level of gestational diabetes who require individualized MNT based on treatment goals, and is best accomplished under the guidance of a dietitian familiar with diabetes treatment. The guidelines recommend that MNT be covered by relevant health insurance. The guidelines emphasize lifestyle changes for people at risk for type 2 diabetes, including moderate weight loss, regular and moderate physical activity, and reasonable dietary control. Physicians should consider the specific needs of patients and their willingness and ability to make changes when developing MNT programs.
