My aunt is 95 years old, has been feeling horribly. she smells a horrible smell even though she does not have body odor. She has been losing weight, been to different doctors, they cannot find anything wrong with her. She does have a meningioma on her brain. She is diabetic, has neuropathy in her legs. BP good. pulses good, no fevers, some diarrhea, no appetite. Has lost 10-15 pounds in last 4-6 months. Has angina. Any ideas?
