Diabetes is a medical condition in which there is little or no insulin production in the pancreas. The result is an inability to process carbohydrates, fats and proteins correctly.

Most patients with diabetes manage their condition well with diet and/or self-administered insulin. Sometimes sugar levels may drop and the patient needs urgent first aid. This condition is called hypoglycaemia.

Symptoms and signs – Not all may be present

  • extreme tiredness and loss of concentration
  • severe thirst
  • dizziness and loss of coordination
  • erratic or argumentative behaviour
  • rapid loss of consciousness if not treated promptly
  • persistent headache
  • pale or sweaty skin
  • can seem drunk

How you can help

1.    If the patient is unresponsive and breathing normally

  • Support the patient on their side and call 111 for an ambulance.
  • Give frequent reassurance during recovery because the patient may be confused until fully recovered.

2.    If conscious, give the patient some sugar

  • If the patient is still fully conscious and able to swallow, give a sweetened drink, chocolate or glucose sweets to suck – an improvement usually occurs within minutes.
  • When the patient is more alert, offer a more substantial carbohydrate meal of a sandwich or several sweet biscuits

3.    Obtain medical advice

  • If the patient has improved with the intake of carbohydrate, medical advice is still necessary because a further deterioration may occur at any time. The patient should see a doctor.

If the patient does not improve after swallowing the sweet food or drink, or if further deterioration occurs and swallowing becomes difficult – call 111 for an ambulance.

See a doctor if you are concerned.

DO NOT try to give the patient a dose of insulin because this can be dangerous unless a medical assessment has been carried out and the patient’s blood sugar level tested.
