What is a hypo?
A hypo happens when your blood glucose level falls too low. Your body is telling you that you’re running low on energy and you need a sugary snack.
What causes a hypo?
- Too much insulin
- A delayed or missed meal
- Insufficient food
- Unplanned or tough exercise
- Sometimes there may be no obvious cause
Here are a few things to watch out for:
- Hunger
- Shakiness
- Mood change
- Sweating
- Lack of concentration
- Fast pulse
- Pallor (paleness)
What to do:
It’s important to treat a hypo as quickly as possible. If you do nothing your blood glucose level will continue to fall and you could become unconscious. You should just relax and get someone to bring you something sugary, such as:
- A glass of fizzy sugary drink, fruit juice or other non-diet drink
- Three or more glucose tablet
- Five sweets
The exact amount you need will vary depending on your individual circumstances. To prevent your glucose from dropping again follow this sugary snack with a longer acting carbohydrate such as:
- Roll/sandwich
- Cereal bar
- Portion of fruit or a pack of dried fruit
- Two biscuits
If after 15 minutes you are still experiencing any signs of a hypo, you should have something sugary or if it is mealtime have your meal. When you’re feeling yourself again, have a starchy snack.
