Rapid weight loss

My mother is 59 yrs. old. She has been slightly overweight for the past 20 years. She eats a high fat diet and has no regular exercise. In the past three months she has lost 47 pounds. It is quite scary to see how ill she looks. My 4 yr. old can see it. My mother has made no changes to her diet or exercise. Her doctor does not seemed concerned. He said she needed to lose some weight anyway. My father and I are both concerned. What do you think?

i think your mother needs to find another dr. this does'nt sound right if she has'nt changed her eating habits. take care. remar

What a nasty attitude from the doctor. yeah she may need to loose that weight, however isn't he listening to you that why all of a sudden she is loosing weight if she has changed nothing about her life.  I would first start with a t-4 level this is her thyroid she may be HYPO thyroid. it may be nothing and it might be something more serious.
if there are more then one doctor in this practice then I would ask to see soemone else or else go back to her doctor and say you want to start to rule thing out do sonme blood work.
good luck
