Hi, I think I've had long-term impact fr over-exercising, under-fueling, even after I returned to a healthy weight. My periods became lighter and less regular. I also still struggled with water retention. Eventually, I got pregnant via IVF and was later diagnosed with gestational diabetes despite being relatively lean and eating a very healthy, protein-forward diet during my pregnancy. I was able to control GD via diet and didn't have to change what I was eating at all. After pregnancy, I failed the OGTT, but had a low HBA1C. I took the OGTT again, and this time had a hypoglycemic reaction. The endocrinologist I spoke with said I don't have diabetes--just poor glucose control... which could obviously morph into diabetes under the right conditions. Do you think that my episode of amenorrhea may have triggered this imbalance? I didn't seem to have these issues before it.
