A family member broke up with his girlfriend of 4 years about a year ago. He's small, about five foot five, always had a little belly, but since the breakup he now looks about 7 months pregnant, and it's only his belly he's carrying the weight. I hadn't seen him for a few months but was shocked to see it. No real weight gain anywhere else. He's always been a drinker but I suspect he's been drinking more recently - could this be the cause and is it a cause for concern re his general health? I'm just a worried relative.
