complications of DM Flashcards
What is hyperosmolar hyperglycemic nonketotic syndrome?
extremely high glucose with profound dehydration. seen in pts with type II DM. it never occurs in type I DM because patients need to have sufficient insulin production to prevent DKA, which is what would happen first if they had no insulin production.
What are causes of hyperosmolar hyperglycemic nonketotic syndrome?
DM2 + lengthy infection, stress, illness
How can you distinguish between hyperosmolar hyperglycemic nonketotic syndrome and DKA?
HHNS usually has glucose levels >800 (and often >1000) and no acidosis or ketosis
DKA can have very high glucose levels, but usually levels are 300-800
What are complications of HHNS
seizure, stroke
What are potential complications of diabetic retinopathy?
vision loss, early catarcts, glaucoma, retinal detachment
What are charcot joints?
foot deformity and joint destruction that occus due to repetitive foot trauma in the setting of impaired pain sensation
What is motor neuropathy like in DM?
may be distally or proximally distributed
may show up as weakness or loss of coordination
What are manifestations of autonomic neuropathy in DM?
postural hypotension, impotence, incontinence, gastroparesis
How can alcoholism lead to hypoglycemia
glycogen depletion and gluconeogenesis ihibition by very high alcohol concentrations (serum ethanol levels greater than 45 mg/dL)
How does adrenal insufficency lead to hypoglycemia?
decr. cortisol leads to insufficient hepatic gluconeogenesis in response to hypoglycemia
