Hi. I am 70 years old and have been a cardiac patient since 2001 angioplasty three times. I take plavix, aspirin, diovan (morning), advant (evening), lipiget 10mg, concor 2.5 mg. The problem i have for a while now is loose motions diaahrea. As soon as i eat something it goes worst and feel weak all the time. Can you please advice as to next course of action. I have done most of the tests and they have come out as negative. Regards
