Types of coma in diabetes mellitus

Hypoglycemic coma is a complication of diabetes caused by insulin overdose or when glucose level gets or remains low after the insulin injection. Appearance of hypoglycemic coma is possible when person that suffers from diabetes mellitus has heavy physical activities in big quantities.

The symptoms of hypoglycemic coma are progressing quickly: in a half of hour or even faster. In that case patient feels a strong hunger, weakness and hyper-sweating, some psycho disorders are also possible too. Later patient may faint, but pulse, arterial pressure and breath will remain normal. Diabetic in coma is manifested by humid skin, muscles contraction, stronger in comparison to normal tendon reflex that is why some convulsions are possible. Eye pupils of diabetic are widened when patient undergoes hypoglycemic coma. The urinal glucose level is under 3 mmol/L.

Comatose and first aid in coma state

Coma in diabetes mellitusUntil time when first symptoms of hypoglycemic coma were manifested first aid must be provided to a patient with diabetes immediately. Any kind of sweetish tea or glucose in any form - sweet, sugar should be given to the patient. Also patient should get warm, especially feet and then immediately without any time loss call an ambulance. In this condition patient needs emergency medical care because the comatose state may lead to cerebral edema that can be lethal.

The hyperglycemic coma has a longer period of development in comparison to hypoglycemia and it lasts from 1.5 to 2 weeks. But that does not make it less dangerous for patient. Primary causes of hyperglycemic comatose condition may be insufficient quantity of insulin or disorders in diabetic's diet, when organism obtains too much fat food rich in carbohydrates.
