The symptoms of a diabetic seizure include uncontrollable muscle contractions and body movements, staring into space and becoming uncommunicative, states RSC Diagnostic Services. A person experiencing a diabetic seizure may slip into unconsciousness. To prevent a seizure, diabetics should look for early symptoms of low blood sugar, such as confusion, muscle weakness, sweating, eyesight changes and slurring of speech, that are a prelude to seizures.
Most people who have diabetic seizures experience them at night, notes Healthline. They may not even notice a seizure occurred, although the seizure often wakes up the diabetic. It is also likely for a diabetic who wakes up in the morning with a headache, sheets damp with sweat and high blood sugar to have experienced a seizure, or at least severely low blood sugar, at night.
Repeated diabetic seizures could be dangerous and cause brain damage, explains Healthline. While these seizures do not cause comas or death, a seizure indicates blood sugar has dropped dangerously low. If a diabetic's blood sugar continues to decline, it could be fatal.
To prevent seizures, diabetics should know the early symptoms of low blood sugar and carry a food that provides quickly digestible sugar, such as juice or candy, to boost blood sugar levels, notes RSC Diagnostic Services. People who regularly experience low blood sugar may want to ask their doctor if they need to carry glucose tablets for emergencies. A person who is unconscious due to low blood sugar needs an immediate injection of glucagon or emergency medical treatment, according to Mayo Clinic.
