Have you ever felt a bit cranky or lethargic, and had someone suggest your blood sugar is low? Or do you live with a condition like diabetes, which means you’re always aware of your blood sugar levels? 

Our blood sugar levels impact how we feel, how our body operates and how we behave. But how variable are they? Can a snack make all the difference to low blood sugar, and can getting a sunburn affect our blood sugar levels? 

In this episode, Dr Gaurav Puri helps us understand how our body converts food into blood sugar, why we need blood sugar and how insulin helps our body regulate levels. He also shares his tips for keeping blood sugar at healthy levels and the advice he gives to patients with diabetes.
