Hi there, Thank you for writing to us. I am sorry to learn about your father. Your father is currently having a failing heart. A failing heart is when the heart cannot pump blood forward and fluid starts to accumulate in the lungs and in other parts of the body like by causing swelling of the lower limbs. Due to a failing heart a person can have problems in the liver as well because the blood from the liver cannot go into the heart because of its reduced pumping function. As a result there is also liver injury as well. As a result of the liver injury one tends to have nausea (feeling of vomiting that he is having) plus since he is on a number of medications, almost all these medications can also cause nausea as well. For the time being, since he has a weak heart, I would like that he should be on medications called as diuretics which take extra fluid out of the body. These medications may reduce the congestion of the liver, any swelling that he may be having in the feet. These diuretics will also improve his shortness of breath as well because these patients become short of breath because of accumulation of fluid in the lungs which is taken out by these medications. Another good choice of medications that would potentially improve his breathing would be a medication from the nitrate group. This also helps with the shortness of breath. His blood glucose are very high and he needs to be managed by insulin. I would not give him any pills with his weak heart. I would like that he should only be on insulin. For the nausea I would like him to be on motilium three times daily prior to meals to increase the movements of the stomach and to reduce nausea. Regards
