Agreed
This should fall into the companies' laps because they didn't take initiative enough to prevent the injury in the first place, and even if it was an accident, it's not right to make the worker who was injured pay for their own weight loss surgery. If it's medically necessary for this surgery to be done, it's not like the employee has any choice in the matter.
Seriously, it's not as if the doctor and the patient are plotting ways to make the company pay more.
The whole 'pre-existing' conditions argument isn't valid here simply because the injury occurred on the job.
Pre-existing conditions should not be discriminated against, no matter what they are. Also, Obesity is something achieved over time. If a company wants to avoid such problems in the future, they should offer fitness programs that help employees stay in shape. (The benefit here is two-fold, because it would likely translate into a productivity bonus as long as the employees aren't pressed for it because they have a fitness program.)
