Tamara and Martin Are Expecting Their First Child, a Girl

Tamara and Martin are expecting their first child, a girl, in a few months. Tamara has a family history of type 2 diabetes, and her mother had gestational diabetes when she was pregnant with her. Tamara has been overweight for most of her adult life, but she began exercising and improved her diet before becoming pregnant. Tamara was recently tested for gestational diabetes, and the test result showed that she has elevated blood glucose levels.  Martin has had type 1 diabetes since age 4. He monitors his blood glucose levels several times a day and takes insulin to manage his blood glucose. Martin has always been a healthy weight, but he does not exercise regularly. His dietary habits also need to be improved to help manage his blood glucose levels. Tamara and Martin are concerned for their family's health and want to do all they can to reduce the risk of diabetes and associated health problems.
