Well Hello der,
Reading about your mother I understand she had alot of pre-existing problems which left her body very weak.As her age is not mentioned here , I'm assuming she must be an elderly lady. I'm really sorry for your loss and i know that there may be a thousand questions racing through your mind.
Lets look at them systematically. She was a diagnosed schizophrenic from an early age and on treatment which has its own long term side effects . A necessary evil cos
schizophrenia should be treated and its a long term thing so side effects could not be avoided.She was a heavy smoker which affected her lungs and heart leading to development of
heart failure and
COPD which are themselves life threatening when present as independent entities in any patient . They were both present at the same time in your mother's case .One need not have a cancer. These two themselves are fatal problems leading to rapid decline in ones health . COPD is the condition where the lungs are damaged mostly due to
smoking as was in this case and are not able to meet the needs of the body resulting in frequent infections and also cardiac failure.Smoking in itself is a major cause of heart failure as it causes degenerative changes in the heart and blood vessels.Your mother was already suffering from two life threatening conditions and this along with the C-diff
diarrhea proved fatal. Diarrhea in itself if not treated promptly proves fatal. So in this case we are seeing three independently life threatening conditions coming together unfortunately, proving fatal in the end.So attributing your mothers death only to the C-diff diarrhea would not be appropriate .
Hope you got your answers.
Take care.
