Diabetic coma

Most diabetics take insulin and carefully time and measure their meals or snacks to control their blood sugar. A coma may result from either too much or too little sugar in the bloodstream. A coma resulting from too much sugar comes on gradually, and the diabetic can usually correct the problem or seek medical

A advice before losing consciousness. A coma developing suddenly – sometimes within 15 to 30 minutes – is likely to be caused by too little sugar. In this case the sufferer may have initial symptoms of dizziness, Iight-headedness, sweating and trembling of the limbs before losing consciousness. Loss of consciousness may be prevented if the person is given glucose (sugar) in the form of chocolate, sugar lumps, sweet biscuits or sweetened tea. If consciousness has already been lost, however, do not try to give anything by mouth but treat the casualty according to the general first aid rules for unconsciousness and arrange for the rapid arrival of a doctor or for the casualty to be transferred to hospital.
