I'm running a .14 fortress, which is fairly peaceful as goblins don't turn up, to get to grips with the new features before updating to a more fun version. So there haven't been many health issues apart from:
A dwarven baby used a shield by her mother when her militia squad ran into a marauding beast. She got a fractured shoulder and a smashed toe as a result. Dwarven healthcare has no paediatric section it appears as she got no treatment at the time but seems fairly robust as she made it to childhood. She then toddled off to a hospital bed and the crack medical team, hitherto completely unemployed, leapt into action. Wounds were cleaned, sutures and dressings applied and the shoulder set. She then left hospital and no further treatment is scheduled. I thought medicine was pretty buggy so I was pleased to see the system work so well, but will she actually heal?
A more general concern is that the luxurious lifestyle in the fortress is taking its toll on the population's general health. A fairly typical description of the average dwarf is 'belarded by great hanging sacks of fat'. Perhaps not surprising as the place is awash in booze and lavish masterpiece meals. Since (as far as I know) cholesterol levels and cardiac arrests are yet to feature in the game I don't know whether to regard this as a good thing, perhaps the fat will act as additional armour when the fighting starts. But are there any strategies I could use, beyond the obvious of designating hundreds of boulders for dumping or making them all miners and excavating enormous caverns, that would get dwarves back to peak fitness?
