No I do not, I think that If you start to loose weight that you are becoming anorexic without the proper exercise and proper nutrition. Why, because without that your just feeding your body less and less stuff and its not the right stuff its like eating less or gorging yourself.
Seek help from medical staff present such as a resident nurse especially if the resident appears to be trying to hurt him or herself or expresses having suicidal ideations. Stay with the resident until help arrives. Also, it is good to try to get the resident to talk as much as possible to offer support, comfort and to diffuse the situation.
