What does generalised weakness feel like with hypoglycaemia?

Your arms and legs may feel weak or trembly, with a hollow or urgent feeling of hunger. You might sweat, look pale, feel dizzy, have a headache, notice a pounding heart, or find it hard to think clearly. Symptoms can appear after missed food, unusual exertion, alcohol, or diabetes treatment that lowers glucose.

Weakness during a suspected low-glucose episode should be treated as a safety issue, especially if you use insulin or another glucose-lowering medicine. Similar sensations can have other causes, so repeated episodes need a clinical review rather than repeated self-treatment alone.

If you are awake and able to swallow, check your glucose if you have a meter and follow the treatment plan given by your diabetes team. Take a quick source of sugar according to that plan, then recheck or reassess as advised and eat a longer-lasting snack if needed. Do not drive or operate machinery while symptoms continue. Never give food or drink to someone who is drowsy or unconscious.

Call emergency services if the person is unconscious, having a seizure, severely confused, unable to swallow, or does not improve promptly with the prescribed emergency plan. Seek medical advice for repeated episodes, symptoms without diabetes treatment, or an episode linked with fainting or injury.

Ask which symptoms should trigger treatment, how medicines and meals should be timed, and whether your glucose targets or prescriptions need review. Record the timing of episodes, food, activity, medicines and any glucose readings to discuss.
