We thought the same thing (that something could be broken) when my MIL 'fell'. She says she didn't fall. But couldn't get up. ???? She still refused to see a doctor or have one come to her and would not let the paramedics take her to the hospital to be checked out. My husband finally did make her realize it was time to do something...so it must have been pretty bad because she never agreed to anything.
All one can do is call 911 and even then, if they get there and they're non-compliant, they can't do anything.
That poor woman, is right, and not only because of the obvious physical issues, but only to imagine what went on in her head. Being that big is not about eating.
