A clinical examination and work up is extremely important for correct diagnosis and management of his condition.Depression,anemia,mineral and vitamin deficiencies, thyroid problems,dementia,liver cirrhosis, kidney disease,cancers,malignancies all can cause loss of appetite and loss of memory. It is suggested to consult a physician and get clinically evaluated. He may further refer you to the concerned specialist. Treatment will depend on the underlying cause. Keep me posted.
Best luck and regards!
Thank you, Dr. Sharma. My husband has a appointment with a Gastroenterologist on Monday and we hope that the Doctor can find out why he keeps losing weight. He's already had several blood workups and many tests and they have found nothing. So, hopefully, we'll get some more blood tests and other tests to see what is causing him to lose weight and not gain since last year's heart surgery. Take care and thank you very much for your time. I will let you know how it turns out.
