How do I manage high HbA1c and fluctuating sugar levels?

Hello,

Welcome to icliniq.com.

I read your query and understood your concern.

At 24 with type 1 diabetes, what you are experiencing is quite typical in the first couple of years, and the key is fine-tuning rather than worrying that things are going wrong. An HbA1c (glycated hemoglobin) of 8.9 % is above target (we usually aim for less than seven percent), and over many years, higher values do increase the risk of complications, but this is not immediately dangerous and can absolutely be improved with better Insulin adjustment and routine.

The shakiness at three o’clock in the night strongly suggests nocturnal hypoglycemia, most often from excess basal (night) Insulin, late exercise, or mismatch with dinner timing. Clinically, I would first look at your basal dose and pattern rather than increasing it. Sometimes a small reduction, shifting timing, or adding a bedtime snack with slow carbohydrates and protein helps stabilize overnight glucose.

Your fluctuating fasting sugars may actually be rebound highs after nighttime lows (somogyi effect), so checking sugar two to three o'clock at night or using a CGM (continuous glucose monitoring) can clarify this. Yes, stress and poor sleep significantly raise cortisol and adrenaline, which increase glucose levels even if the diet is unchanged, so your observation is valid.

The fatigue and irritability are also expected with glucose variability and will improve as control stabilizes. The practical plan is to tighten monitoring, especially overnight, review basal Insulin rather than just correcting highs, aim for gradual HbA1c reduction, and work on sleep consistency. If possible, discussing a structured basal–bolus adjustment or CGM use with your diabetologist will make a significant difference.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.
