Q

Obese 400lb man lost 40 lbs in the last 6months due to starvation, before beginning refeeding what would be considered

Watch for refeeding syndrome the body can start using glycogen from the over during times of starvation. If food is reintroduced to fast the body will have insulin spike causing k/mg/p to be taken up into cells, depleting the system leading to adverse effects. Possibly death.

educate on nutrition start on ssri refer to psych
30
What is wet beriberi
seen in thiamine (B1) deficiency due to high physical exertion and increased carbs effects cardiovascular system causes peripheral vasodilation, edema, warm extremities mimic cellulitis also tachycardia with High output heart failure =>pulmonary edema => dyspnea,
31
Dry beriberi
seen in thiamine B1 deficiency affects central and peripheral systems leading to neuropathy lower > upper and wernicke-korsakoff
32
Treatment of thiamine deficiency
3 days 50 to 100mg/day thiamine IV, then 5 to 10mg qd
