In a person with diabetic ketoacidosis, what are the cellular events

No insulin --> cells produce ketones and less K+ enters the cells ECF H+ rises, then H+ enters the cells and K+ leaves But due to osmotic diuresis, excess electrolytes are lost hence ECF K+ does not rise Once you give insulin, K+ moves back into the cells and ketone production is reduced Without insulin, there is a risk of hypokalaemia
