telogen effluvium Beau's Lines diffuse hair loss metabolic disturbance

TLDR A man had nail and hair changes months after severe Covid-19, showing long-term effects.

In 2020, a 64-year-old man tested positive for SARS-CoV-2 and experienced severe symptoms that required hospitalization. He lost 8 kg during his illness. Four months after his recovery, he noticed transverse depressions, or "Beau's Lines," in his fingernails, which are caused by a metabolic disturbance from a major systemic illness interrupting nail growth. He also reported a period of diffuse hair loss one month prior, suggesting he had experienced telogen effluvium due to the same metabolic disturbance. These clinical signs highlight the long-term impact of Covid-19 on survivors.
