Three complications of diabetes mellitus
Ketoacidosis
Hyperosmolar nonketotic coma
Hypoglycaemia
What is ketoacidosis?
It occurs when sodium potassium and ketones are lost in urine
Increased requirement of insulin
Blood sugar levels increased in response
Dehydration and electrolyte imbalance occurs
Fats, broken down to liberate glucose
Ketones produced as a byproduct
What is hyperosmolar non-ketotic coma?
Blood serum is hyperosmotic, highly concentrated with glucose
This draws fluids from interstitial spaces, which is then excreted through increased urination and often contains glucose as well
Person becomes dehydrated and extremely thirsty
Leads person falling into lethargy, then coma
