Hello, you have not mentioned what kind of insulin you re using. I cannot give you a specific response without full knowledge of your treatment. I can give you general advice about your diabetes though. Blood glucose levels vary depending on physical activity, eating and insulin dosage. Other factors may kick in and complicate things, like illnesses, drugs etc but I m talking about the basic rules of glucose regulation. Even if everything is the same your blood glucose may exhibit a small variability. For a young person like you intensive blood glucose control is essential, in order to avoid early appearance of diabetic complications. Whatever does the job is great, but my opinion is that a basal-bolus regimen is the best. This consists of a basal insulin (preferably glargine, detemir or degludec because nph can be troublesome) once a day (or twice depending on the chosen insulin) and three injections of fast-acting insulin. Getting your fasting glucose back to track should be your first priority. Basal insulin should do that. Stick to a healthy diet plan, exercise regularly and adjust your basal insulin dosage until your morning blood sugar is normal or near-normal. You can adjust the rapid-insulin later. Your doctor should inform you about carbohydrate counting so that you will be able to adjust fast insulin dosage yourself. This the general idea. If you have more questions, or you need me to clarify anything, please ask again! Kind Regards!
