An abnormally diminished concentration of glucose in the blood. This occurs when a person with diabetes has injected too much insulin, eaten too little food, or has exercised without extra food. Taking small amounts of sugar, sweet juice, or food with sugar will usually help the person feel better within 10-15 minutes. Symptoms of hypoglycaemia include nausea, sweating, weakness, faintness, confusion hallucinations, headache, cold sweat, piloerection, hypothermia, irritability, bizarre behaviour and fainting. Prolonged hypoglycaemia can result in complete loss of consciousness, convulsions, coma and brain damage. |
