PRESENTING PROBLEM: Hyponatremia [E87.1] Chronic obstructive pulmonary disease, unspecified COPD type (HCC) [J44.9] COVID-19 [U07.1]   HOSPITAL COURSE:  Patient is a 70 y.o. male with past medical history of COPD, hearing loss, smoker, ETOH, marijuana use, polio osteopathy of lower right leg. Patient is currently not on any home medications. He has a past medical history of chronic obstructive pulmonary disease but does not use bronchodilator medications at home. Last PCP visit was a year ago, but prior it was over 6 years ago. He is a poor historian.    He presented to hospital today with confusion, weakness, and multiple falls. Due to severe weakness he has had multiple falls- unclear if he has had any head trauma. Wife at bedside reports patient became dizzy one week ago and fell in bath tub. Then on Sunday he started to have diarrhea, became weaker, fell out of bed, and tested positive for COVID. Wife reports since he has became increasingly weaker, confused, and decreased appetite. She reports he did feel warm to touch and he was complaining of chills. He arrived to the ER in a wheelchair due to severe weakness- unable to ambulate on his own.    In the ER, patient required supplemental oxygen per ER physician. VBG unremarkable. Remained afebrile. NA 119, AST 175, ALT 53. CBC unremarkable. Film array revealed COVID positive. Head CT revealed no acute intracranial abnormality. Chest xray revealed subtle increased opacity in the region of the right middle lobe may be related to infection. No evidence of pneumothorax or large pleural effusion.    During hospitalization, sodium level was slowly increased from 119 to 128. Hyponatremia most likely secondary to hypovolemia due to poor oral intake. NA 119->124->125->128->129-> 128. Patient discharged with daily sodium tabs.
