Symptoms of low blood sugar in type 2 diabetes

The body releases stress hormones as glucose falls, which may cause sweating, trembling, hunger, a racing heartbeat or sudden irritability. The brain may then be affected, causing dizziness, nausea, unusual behaviour, blurred thinking, weakness or difficulty speaking. Symptoms vary, and a person may notice a different warning sign each time.

These symptoms do not prove that low blood sugar is the cause. Check glucose when possible and consider meals, medicine, alcohol and recent activity. Someone with type 1 or type 2 diabetes can have similar symptoms, so the treatment plan and reading matter.

If the person is alert and can swallow, use the fast-acting carbohydrate and rechecking steps provided by their diabetes team. Once recovered, follow advice about a snack or meal. Pause driving and risky tasks until fully well. Keep a written plan and tell people close to you how to recognise your symptoms.

Emergency help is needed for severe confusion, seizure, fainting, unconsciousness or inability to swallow. Do not give food or drink to an unresponsive person. Seek prompt review if symptoms repeat, occur without an obvious trigger or continue after the prescribed response, because medicine and meal timing may need adjustment.

Ask which symptoms are your personal warning signs, when to check glucose, what treatment to carry, and how to adjust plans for exercise, travel, illness or missed meals.
