Hi, There is no study to link the blood sugar level to clexane. However, Progesterone can definitely cause increased blood sugar level due to its action on hepatic gluconeogenesis pathway in liver as well as due to its action of increasing insulin resistance and hence increased blood sugar level. This effect is more in Type 1 diabetic patients. You are rightly trying to adjust the dose of Novorapid to stabilise your blood sugar level to normal. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Satnarain Bansal, General & Family Physician
