Coma in diabetics
Abnormal glycaemia
(a) Hypoglycaemic
(b) Hyperglycaemic: (i) ketoacidotic, (ii) non-ketoacidotic
Other metabolic, consequent upon the diabetic state
(a) Uraemic coma, with or without glycaemic upset
(b) Lactic acidosis, with or without glycaemic upset
(c) Alcoholic coma, with possible abnormalities in ‘ketone bodies’, lactate, or glucose
Non-metabolic coma
For example, subarachnoid haemorrhage
MAJOR ACUTE COMPLICATIONS
Metabolic problems
■ Nonketotic hyperosmolar hyperglycemic coma
■ Hypoglycemia
■ Diabetic Ketoacidosis (unlikely in type II diabetes mellitus except during periods of stress such as those caused by trauma and intercurrent infection or disease)
■ Lactic acidosis
Infection
Hyperglycemic crises
DKA, NKHHC
Acute complications of DM
DKA
► Acute complication of type 1 DM
► Occasionally occurs in type 2 DM
► An Endocrine Emergency
► With a mortality rate of 5 – 10%
► Life threatening condition but preventable in many cases
► Results form absolute insulin deficiency or relative insulin deficiency combined with counter-regulatory hormones excess (mainly glucagon excess)
