Patient With Polydipsia and Weight Gain

      Frank is a 52-year-old man complaining of excessive thirst. He was in his usual state of health until about 3 to 4 weeks ago when he experienced a significant weight gain that he blames on the stay-at-home order in response to the COVID-19 pandemic. He has been lonely and depressed and sitting at home “eating everything in sight.” Over the past week he has noticed increasing thirst, urinary frequency, and blurred vision.
