Water deprivation : The classic diagnostic test first is a first morning urine sample for osm after not drinking and if greater than 300 excludes the diagnosis. Water deprivation in the hospital stop intake and check serum/urine osm every 2 h. If serum sodium rises greater than145 wihtout rise in urine osm the diagnosis is made. Vasopressin is given if the urine osm increases it is central di if not nephrogenic di.

Dehydration test: The dehydration test is used to diagnose diabetes insipidus. This test is typically performed at an endocrinology office. It involves not drinking any liquids for 12 hours and then labwork is done in the morning and six hours later.

Small portions: You need to have an honest, realistic assessment of your calorie needs per day which is generally too much. It is based on your prepregnancy height and weight. You need to eat unprocessed food. Make your food yourself. You need to eat a tremendous amount of vegetables of all sorts. The bulk of your plate should be filled with vegetables. Eat a lot of fish for your protein source.

Varied: The answer depends on how well controlled the diabetes is. If poorly controlled at conception, increased risks of miscarriage and birth defects. If moderately to poorly controlled during pregnancy, risks of fetal demise. If sugars not well controlled these infants have a number of risks including difficult or dangerous vaginal births because they can be so large in size. Control is critical!

Yes: Keeping you blood sugars in good control can decrease the complications of gestational diabetes (gdm). Uncontrolled gdm can cause large babies, increasing the risk of C-section and the baby's shoulders getting stuck. It can also cause increased amniotic fluid which can cause the baby not to stay head down and increased abdominal pressure. Babies can have low sugars, jaundice and feeding problems.
