My husband had a pacemaker/defibrillator put in a month ago.  Since then he has been able to eat very little - eats mostly yogurt, Ensure, fruit, etc.  His stomach feels like its filled with air.  He also got pneumonia, then congestive heart failure.  Could it be medication or an after-effect of what he has been through.  We see the cardiologist Friday and hope well get some answers.  But maybe you can come up with some answers.  Thank you.
Hello Thanks for posting at Chat Doctor. Loss of appetite after a pacemaker/defibrillator insertion is uncommon. But it is common after a pneumonia or congestive heart failure. I think the loss of appetite is as a result of the pneumonia and heart failure. Medications like antibiotics can also decrease appetite. You have to ensure that his nutrition is proper. Ensure is a good protein supplement along with fruits and milk products. Antibiotics are usually continued for 10-14 days after pneumonia depending on severity. He will gradually regain his appetite. There are some appetite boosting medications also like syrup activate or spy negative elixir. These brands can have different names in different countries. I don't know which country you are from. You can ask your doctor for appetite boosting medications. It is the course of disease and a pneumonia and congestive heart failure can take about one month for the patient to recover. Wishing him good heath. Regards
