Why your insulin might not be working effectively
Siddhartha JanaDose matters, not just injection
Taking insulin isn’t enough—correct dosage is crucial. An incorrect or outdated dose may not lower blood sugar effectively, even if taken regularly.

Rotate injection sites
Repeatedly injecting in the same spot can cause fatty lumps (lipohypertrophy), which interfere with insulin absorption. Always rotate injection sites.

Inject in the right areas
Use areas with fat—like abdomen, thighs, upper arms, and buttocks. Avoid injecting into muscle, as it affects how insulin works in the body.

Use proper needle technique
Needles longer than 4 mm can reach muscle if not used properly. Wait 5 seconds before removing the needle to avoid insulin leakage and ensure full delivery.

Store insulin correctly
Insulin must stay refrigerated. Leaving it out for 1–1.5 hours or exposing it to heat can reduce its potency and affect blood sugar control.

Insulin needs support
Insulin alone doesn’t control diabetes. Balanced diet, physical activity, proper sleep, and stress management are equally important for glucose control.
