Hi I am a man, but I have written the web site thriftygene.net. I will bet (you name what) that all women with the glucose tolerance test explained on my site, when not pregnant, will get gestational diabetes. I do not know if this is the only population which gets gestational diabetes. Can you give me evidence for or against that. Thriftygene.net This “thrifty” gene exists throughout the world. Women with this form of glucose tolerance test get gestational diabetes. People with my gene tend to be fat. Thriftygene.net explains all and maybe explains type 2 diabetes. I am selling nothing.
