A 67-year-old African American male presents to the clinic with a chief complaint that he has to “go to the bathroom all the time and I feel really weak.” He states that this has been going on for about 3 days but couldn’t come to the clinic sooner as he went to the Wound Care clinic for a dressing change to his right great toe that has been chronically infected, and he now has osteomyelitis. Patient with known Type II diabetes with poor control. His last HgA1was 10.2 %. He says he can’t afford the insulin he was prescribed and only takes half of the oral agent he was prescribed. Random glucose in the office revealed glucose of 890 mg/dl. He was immediately referred to the ED by the APRN for evaluation of suspected hyperosmolar hyperglycemic non ketotic syndrome (HHNKS). Also called hyperglycemic hyperosmolar state (HHS).

Question:

Explain the underlying processes that lead to HHNKS or HHS.
