This Hypo Awareness Week (5 -11 Oct 2020), Diabetes UK wants to shine a spotlight on hypos. Hypos (short for hypoglycaemia) affect nearly everyone with type 1 diabetes, and many people with type 2 diabetes, who use insulin or certain other diabetes medications. See the video.
Hypos can be scary and dangerous and are certainly not pleasant to experience. They can lead to blurred vision, confusion, seizures and, in severe cases, unconsciousness and coma. Raising awareness of hypos could help save lives if everyone was aware of the signs – whether for themselves or for someone with diabetes around them.
A hypo is when the blood sugars drop too low, below 4mmol/l – this can be dangerous if not treated immediately, as it means the brain does not have enough energy to work properly. This can happen for various reasons, including taking too much insulin or other diabetes medications, missing a meal or missing calculating carbs, unplanned physical activity, or even hot weather. Sometimes, there is no explanation for a hypo which can be frustrating.
For many people living with diabetes, hypos are part of life. But this shouldn’t be the case because hypos can be scary and dangerous. They can lead to blurred vision, confusion, seizures and, in severe cases, unconsciousness and coma.
That’s why they must be treated quickly with fast-acting sugar, so that blood sugar levels rise again.
Good hypo treatments include sugary drinks (not diet versions), fruit juice, glucose tablets or gel, or sweets like jelly babies. Treatments that are not as effective are chocolate (the fat in chocolate means the sugar takes longer to get into the blood) and whole fruit like a banana (the fibre slows down absorption of the sugar).
If someone tells you they have diabetes and are having a hypo, you can help them to find or get a sugary drink or some sweets, and if they become unconscious call an ambulance. If you have diabetes and you are experiencing frequent hypos, speak to your healthcare team who can support you to make changes to your medication or insulin doses.
