Hi doctor,

I am a 42-year-old female. My fasting sugar level is 135 mg/dL, and postmeal, it is 130 mg/dl. My BMI is 18. I am taking tablets Metformin 500 mg, and Glimepiride 0.5 mg twice daily. I want to know if this increase in fasting blood sugar is due to Somogyi effects, the dawn phenomenon, or a decrease in basal insulin. Should I take insulin? Please help.



Welcome to icliniq.com.

I understand your concern. The higher blood sugar level in the morning can be due to low insulin in the body, eating less, or skipping meals at night, which may lead to rebound high blood sugar. So, as blood sugar is not very high, insulin is not required. But, with better lifestyle management and oral medications, high blood sugar levels can be controlled. Therefore, I suggest you follow the following instructions mentioned below to help in controlling your blood sugar level. Do not skip meals. Instead, try to eat small portions at regular intervals. Exercise daily to reduce body fat and increase insulin sensitivity in the body. I hope this has helped you out. Take care.
