I have read carefully and analyzed your concern. I understand you are worried about that some problems might inherit to your children. Let me assure you there is no harm to your marriage, if you are a diabetic or what blood group you have. Regarding your child Chat Doctor. If you are a woman with type 1 diabetes and your child was born before you were 25, your children risk is 1 in 25; if your child was born after you turned 25, your children risk is 1 in 100. If both you and your partner have type 1 diabetes, the risk is between 1 in 10 and 1 in 4. In general, if you have type 2 diabetes, the risk of your child getting diabetes is 1 in 7 if you were diagnosed before age 50 and 1 in 13 if you were diagnosed after age 50. Some scientists believe that a children risk is greater when the parent with type 2 diabetes is the mother. If both you and your partner have type 2 diabetes, your children risk is about 1 in 2. In my opinion, there is no harm in marrying her. I wish you best of luck. Hope I have answered your query. If you do not have any clarifications, you can close the discussion and rate the answer. Wish you good health.
