<s>[INST] my husband has had a by pass 10 years ago  in 3 major veins he also had a stent put in one of his veins lately. HE ALSO HAS DIABETES.He stopped all his heart pills except those of diabetes.He is now spitting blood especially in the morning. Do you think that this is because of the stent? Thank you [/INST] Hi, dear. I have gone through your question. I can understand your concern. Spitting of blood may be due to many reasons.  He may have cirrhosis of liver or some problems in lung. You should go for ultrasound abdomen and x-ray chest.  Search the cause and take treatment accordingly.  It's not due to stent. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
