Many Swedes live with fatty liver – and it doesn’t have to be dangerous. But for some, it kicks off a course of disease in which persistent inflammation leads to cirrhosis. Medicinsk Vetenskap has talked to researchers who look after the liver – the behemoth of the belly that has a somewhat magical ability to recover, along with enormous overcapacity.
