10 Fast facts about hypoglycemia (low blood sugar)
Hypoglycemic episodes (hypos) can be a scary experience for all involved: here’s what you need to know to deal with one.
- A hypo is a sudden low blood sugar episode.
- The optimal blood glucose range is 4 to 7mmol/l. With a hypo, blood glucose levels are usually lower than 3mmol/l.
- Initial symptoms are nervousness, sweating, intense hunger, trembling, weakness, palpitations, or trouble speaking (depending on the person).
- The best thing to treat a hypo is fast-acting carbohydrates: 15-20g of sugary carb (a few sweets, 2 tablespoons of raisins, a tablespoon of honey or half a cup of fruit juice).
- The key is to catch low blood sugar early – as soon as it starts dropping – and treat it with a small dose of something sweet.
- If blood glucose drops too low it can get to the stage where the brain is not getting enough glucose.
- Symptoms of this are confusion, drowsiness, changes in behaviour, seizure and eventually coma.
- In case of a severe hypo, a glucagon emergency kit may be necessary. This once-off injection instantly raises the blood sugar, and is particularly useful when the person with diabetes is unconscious or unable to swallow.
- Notify all those close to you what to do in an emergency and how to use a glucagon injection.
- Test often to keep your levels as well controlled as possible.
