Many diabetics using tablets or insulin occasionally experience some form of hypoglycaemic reaction when their blood sugar drops too low. It may occur at any time. Quite often it occurs before a meal or after an exercise, sometimes up to 10 hours after an exercise.
Symptoms vary from person to person, but typical early signals are:

• Sweating
• Shaking

Other symptoms include:

1. Faint
2. Cold
3. Irritable
4. Hungry
5. Tired
6. Confused

• Headache and blurred vision are other possible symptoms.
