Summer Heat & Diabetes: Why Blood Sugar Fluctuates & How to Stay Safe

• Dehydration is the primary cause of high blood sugar in summer, as reduced water thickens blood and increases glucose concentration.
• Kidneys struggle to excrete excess sugar when dehydrated, adding stress to the body.
• Heat increases stress hormones, disturbing sugar levels; some experience sudden drops due to dilated blood vessels and faster insulin absorption.
• Consumption of sugary cold drinks, packaged juices, and ice cream elevates blood sugar quickly.
• Stay hydrated with water, lemon water, or buttermilk; store insulin in a cool place; monitor sugar levels frequently and consult a doctor for changes.
