Flashcards

What is the first safety screen in weight gain?rapid gain with edema/dyspnea; pregnancy complications; Cushing features
Name three high-yield causes of weight gain.hypothyroidism; Cushing syndrome; fluid retention/heart failure
Which investigation anchors the initial weight gain workup?TSH

Practice Questions And Cases

A learner is evaluating a patient with weight gain. Which finding should most strongly shift the next step toward urgent escalation?

Create a problem representation, rank the differential, choose the first investigation, and state the immediate management priority.
