Kids and teens with type 1 diabetes tend to have much lower levels of melatonin, the body's sleep hormone, in the morning compared to healthy kids their age. This suggests that having diabetes might be linked to changes in their natural sleep-wake cycle or metabolism.

Kids and teens with type 1 diabetes tend to have lower levels of the sleep hormone melatonin in the morning. This drop in melatonin isn't just because of their age, gender, or weight, but seems to be directly connected to having diabetes itself.

Children with type 1 diabetes tend to have about 41% less melatonin in their blood in the morning compared to healthy kids. This lower hormone level might disrupt their body's natural balance and affect how they process energy and regulate metabolism.

Giving insulin to kids with type 1 diabetes seems to lower their melatonin levels. This might happen because insulin and melatonin compete for the same receptors in the body, showing how these two hormones work together to control metabolism.

Taking melatonin supplements seems to lower fasting blood sugar levels in adults by about 11.6 mg/dL on average. This effect is strongest in people whose blood sugar is already normal or only slightly high, but researchers caution that the current evidence isn't strong enough to rely on melatonin as a main treatment for blood sugar control.
