Low serotonin levels linked to long COVID, new study says

There’s a new breakthrough this week in the search for what causes long COVID — the lingering and often disabling symptoms that last for months, even years after a COVID infection — including intense fatigue, breathing problems, heart palpitations and brain fog.

But researchers from the University of Pennsylvania just published a new study suggesting that there may be a connection between low serotonin levels and long COVID.

We hear from Elizabeth Cooney, who’s reported on this for our partners at STAT News, the health and medicine publication.
