Lantus and Humalog are prescription-only insulin medicines, and the correct doses depend on your son's blood sugar levels, age, weight, diet, and activity. Please consult his doctor, who can review his condition and safely prescribe and adjust these medications.

An HbA1C of 8.5% means your average blood sugar has been higher than the healthy target range over the past three months, which suggests that your diabetes is not well controlled at the moment. The safest and most effective way to bring it down is not through a quick fix, but by working closely with a healthcare professional who can review your current treatment, guide you on diet and exercise changes that fit your lifestyle, and monitor your progress with regular follow-ups. This personalised approach ensures your HbA1C can be lowered safely and sustainably.

A post-meal sugar level of 300 mg/dL with weight loss and weakness suggests your type 1 diabetes is not well controlled and needs medical attention. You may require adjustment of your insulin dose, proper meal planning, and checking for ketones to rule out complications. Please consult your doctor immediately, as timely insulin correction and monitoring can prevent serious problems.

Her fasting blood sugar may be high because Humalog is a rapid-acting insulin that works mainly around meal times and does not last long enough to control blood sugar overnight. Other factors may include diet, late-night snacks, delayed stomach emptying, stress, illness, or insufficient basal insulin. She should discuss this with her doctor, who may adjust her insulin or treatment plan to achieve better blood sugar control.

To manage sugar spikes after breakfast and lunch, monitor your blood sugar regularly, adjust the timing and dose of your insulin as advised by your doctor, and focus on balanced meals with controlled carbohydrate portions. Include fibre and protein to slow the absorption of sugar.

You should not adjust your Humalog dose on your own. An HbA1c of 8.5 indicates that your blood sugar is above the recommended target. Please consult your doctor, who can review your blood glucose patterns, diet, and lifestyle, and safely adjust your insulin regimen if needed.
