How often does gestational diabetes go away for the rest of your life?

It does not. The finding of gestational diabetes (gd) is a marker that you will develop diabetes later in life. Young latina women with gd will almost invariably develop diabetes within 10 years. Ask your doctor what drug or lifestyle measures you can take to stave off the development of dm.
Depends on your diet. Gestational diabetes is the result of excessive sugar and carbohydrate intake which causes high blood sugar levels, which then make your Insulin levels rise. Plus the hormone changes in preg make prob worse. . Over time the chronically high Insulin levels lead to Insulin resistance and you will need to make higher and higher levels of insulin. Go on a zero sugar low carb diet to reduce problems.
