Can stress and poor sleep affect blood sugar levels? Top doctors answer this, and more

Welcome to another edition of Hello, Doctor — the TOI+ series that connects India’s leading specialists directly with our readers. Each week, subscribers write in with personal health questions, our editors curate the most relevant ones, and top clinicians respond with clear, evidence-based guidance written in simple, everyday language.
The purpose remains the same: to cut through the clutter of generic wellness tips and online misinformation, and instead connect readers with trusted, experienced voices. These are not abstract medical discussions — they are real questions from TOI+ subscribers, answered with clarity, context and care.
