What is diabetes?

Diabetes is a medical condition that affects blood sugar levels. Normally, people’s bodies maintain the ideal blood sugar levels automatically. When a person has diabetes, their body fails to maintain the blood sugar balance, so they need to manage it through diet, tablets or insulin injections.

Sometimes, a person who has diabetes can suffer diabetic emergencies, which require first aid.

What are the signs and symptoms of a diabetic emergency?

Signs and symptoms vary, but common ones include:

  • hunger
  • clammy skin
  • profuse sweating
  • drowsiness or confusion
  • weakness or feeling faint
  • sudden loss of responsiveness.

Back to questions

What happens in a diabetic emergency?

In most cases, the person’s blood sugar levels become too low. This is called hypoglycaemia. It can happen when the person has missed a meal or exercised too much. If left untreated, a diabetic emergency can become very serious.

Back to questions

What should I give them to eat or drink?

You can give them sugary drinks such as cola, lemonade, fruit juice and isotonic sports drinks, and sweet foods such as jelly beans, chocolate and sugar cubes. The person may also be carrying glucose gel or tablets. Avoid giving them a diet drink, as it won’t have any sugar in it and will not help them.

Back to questions

But some people have high blood sugar levels, so won’t giving them sugary drinks or food make their diabetic emergency worse?

Some people do have high blood sugar levels, but giving them sugary drinks or food is unlikely to do any harm.

Back to questions

How will I know if this is a long-term condition for the person?

They should be able to tell you, so listen to what they say. They may have some form of identification on them (e.g. a card, bracelet or necklace) that will give you information about their condition, or they may be carrying an insulin pen, glucose gel or glucose tablets.
