Can abilify (aripiprazole) mask some symptoms of an underlying physical illness/ disease?

Yes: That is why it is appropriate to have necessary blood tests and imaging studies and any other type of medical testing done that your family doctor or psychiatrist feels is necessary prior to starting you on abilify (aripiprazole).

yes in general: Almost all meds used in psychiatry may control symptoms provoked by general conditions. In that context, if the obvious or only symptom is the psychiatric correlate, the real diagnosis may be obscure. That s why pcp and psychiatrists try to search for medical causes, including intoxications, etc. Before diagnosing a psychiatric disorder, even if treating it.Ask your dr about your particular case.
