It is unusual for a healthy female on medicines to suddenly develop a body odor like maple syrup. This is rare but is seen in some metabolic disorders. These rare disorders are trimethylaminuria, maple syrup urine disease etc. In both the disorders there is incomplete break down of certain amino acids in the body, which can cause this peculiar smell. Other possibility is diabetic ketoacidosis. But that is usually accompanied by other symptoms like increased thirst, increased urine output, weight loss etc. To determine whether you have any of the metabolic disorders, you would need to undergo plasma and urine amino acid levels, before starting treatment. I would recommend you to consult your doctor for a detailed evaluation.
