How Acarbose Works

Scientific Answer:
- Acarbose blocks digestive enzymes in the gut
- These enzymes normally break down carbohydrates into glucose
- Slower breakdown means slower glucose absorption
- Post-meal blood sugar spikes are reduced
- Helps improve overall glucose control in diabetes

Simple English explanation with example:
- Carbs usually turn into sugar very quickly
- This causes sharp blood sugar rises after meals
- Acarbose slows this process down
- Sugar enters the blood more gradually
- Like sipping a drink instead of gulping it
