Hi. Losing two and a half stone in a matter of 3-4 months is really cause for concern, although it is still
possible that the weight loss is due to your chronic debilitating medical condition (the multiple sclerosis,
as well as the urinary tract infection and pleurisy). It is also possible for the Morphine to contribute to
the weight loss by dulling appetite and causing abdominal fullness. It might be best to talk with your doctor
about this, so you can be tested for any other conditions. Cancer is always one of the possibilities which
need to be checked when there is unexplained weight loss.
