Expatriate health insurance customers might want to discuss the risks that contribute to cirrhosis of the liver with their doctors.
According to research from the Sahlgrenska Academy, being overweight could be a bigger risk than alcohol consumption.
The study looked at 855 men from the age of 50 for up to 40 years. None of those monitored had problems with their liver to begin with.
However, by the end of the research, almost two per cent had been diagnosed with cirrhosis of the liver, all of whom were overweight at the beginning of the study, with an average body mass index of 28.
But a similar link could not be found between alcohol intake and cirrhosis of the liver.
Jerzy Kaczynski, docent at the academy, commented: "A liver that has been ill and weakened as a result of overweight can take less of a load.
"We can therefore speculate that cirrhosis of the liver will develop more quickly in people who drink too much alcohol if they are overweight. Our study does not offer any evidence for this, but this kind of speculation is well founded."
