I am 6 weeks pregnant now. Insulin requirements have already more than doubled compared to 4 weeks ago (up to TDD of 50 units/ day as of yesterday, compared to about 20 -25 U/ day under normal conditions).
Your type of diabetes may be autoimmune, however, pregnancy hormones and the placenta massively increase insulin resistance. Thus the relative lack of insulin, or inability of the pancreas to ramp up insulin production, become a problem during pregnancy.
I was diagnosed very early in my first pregnancy 9 years ago. Insulin ever since. Typically quite low doses required, except during pregnancy when my requirements soar.
I am antibody negative (for the antibodies tested), but have low c-peptide too. Interestingly, both of my daughters also have higher than normal blood sugars levels (negative antibodies, and the oldest has low-normal c-peptide), which are currently being contolled on low carb diet and under monitoring. So definitely something genetic happening in my case. Though my identical twin sister apparently doesn’t have the same issues…
Insulin is the standard care for diabetes in pregnancy. Eating a low carb diet is also helpful (Baby doesn’t need carbs which are simply C-H-O molecules), baby needs stable blood sugar levels (normal blood sugar levels are lower during pregnancy than outside of it).
This is now my 3rd pregnancy (unexpectedly), and I have heaps of experience from the first two, and adding to it now. So please ask questions, if you have any, and I’ll do my best to share my experience…
