Thanks for posting your query.

If you are getting hypoglycemia in the morning hours at 4 am and 6pm then you may have somogyi phenomenon.

In such cases, patient has hypoglycemia at early morning and because of body mechanism, blood sugar in fasting condition is very high and doctors generally increase the dose of insulin. This will further deteriorate the condition. Treament requires sequential reduction in the dose of insulin.

Istament 50/1000 contains sitagliptin and this is DPP -IV inhibitor and by its mechanism, it will inhibits insulin metabolism thus insulin works for more hours.

If you are getting hypoglycemia at evening time, then dose of insulin/ other medication must be reduced.

Are you over weight?

Have you family history of diabetes?

Generally in type I diabetes,oral hypoglycemic agents donot work. You should consult with yor treating physician/ endocrinologist whether you have Type I diabetes or Maturity onset diabetes in young.

You should go for regular blood sugar check up: before breakfast, 2 hours after breakfast, before dinner and 2 hours after dinner.

Put your query if you have.

Best regards,

Dr. Mayank Bhargava

Considering your all data's, your diabetes appears to be type I DM.
You should go for metaday and pioglar as both of these medication improves insulin sensitivity.
Take care,
