Hi,
Since the age of patient is 83, all the organs are also aged and hence respond slower than the younger people. your Mother is already on
Coumadin which is a blood thinner.
Loss of appetite is common and the cause can be anything that needs consideration. Antibiotics, changed atmosphere, may be first surgery in her life, other medicines and so on can be the cause which needs to be found out and the medicines changed or stopped.
Reassurance plays a vital role and should by done by family members and Medical professionals by
counselling and medicines if required.
Identify and stop the medicines that are interacting and causing the symptoms.
Multivitamins, minerals and trace elements helps a lot.
PPI like
Pantoprazole, antacids as and when needed,
I hope
hernia surgery is successful and healing well.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
