<s>[INST] Dear Doctor, My father got his angioplasty done last month on 1st june 2010. But, he has been experiencing stomach upsets like constipations since then. Also, he complains of constant weakness in whole body. Could you please suggest, why this is happening ? and in how much time will he get normal ? [/INST] Hello, I understand your concern and would explain that your symptoms could be related to antiplatelet agents. For this reason, I recommend checking his complete blood count for anemia and performing a fibrogastroscopy. Cardiac ultrasound is also necessary in order to exclude heart failure. I would also recommend checking thyroid hormone levels for possible thyroid gland dysfunction and blood electrolytes. Depression cannot be excluded either. If all the above tests result normal, I would recommend consulting with a specialist in this field. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Ilir Sharka, Cardiologist </s>
