sugar values are mostly within or near normal range. Mild fluctuations alone usually do not cause persistent insomnia. Stress, anxiety, irregular sleep schedule, excessive screen use, caffeine, or health-related worry can also disturb sleep.
If low sugar symptoms (sweating, palpitations, tremors) occur, consult a physician/endocrinologist for evaluation. Meanwhile, maintain regular meals, avoid late-night caffeine, and follow proper sleep hygiene. If insomnia persists beyond 1–2 weeks or anxiety is prominent, a psychiatric consultation would be helpful.
