Can exercise lower blood sugar?
Answered by the AskDoc Medical Team · Medically reviewed under our Medical Director, MBBS
Yes, twice over. During movement your muscles pull sugar from the blood without needing insulin, which is why a 10 to 15 minute walk after meals visibly flattens the after-eating spike. It is one of the cheapest tricks in metabolic health.
Regular training also makes your body more sensitive to its own insulin for a day or two after each session, and strength work adds muscle, which is where sugar gets stored. For prediabetes, this is a large part of why lifestyle programs work.
If you take insulin or medicines that can cause lows, talk to your doctor about doses before big changes in activity, and carry fast sugar during exercise. For everyone else, the after-meal walk is the easiest place to start today.
