Thanks for your question on Chat Doctor. I can understand your concern. He is having severe hypotension which is causing dizziness. Chronic lung disease can cause heart failure. He also had bypass surgery and have diabetes. So he is at risk of heart failure. So his hypotension is mostly due to heart disease. So immediately take him to hospital and consult cardiologist and start treatment. He will need isotropic Chat Doctor.  Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
