My 90+ years old grandfather is refusing to eat anything at all. He was leading a normal 'aging' life when he started deteriorating a month back after an episode of diarrhea. His diarrhea got cured. Infact he very soon started becoming constipated. He coughed a lot. Refused to eat. Had high fever. We called two- three physicians to check him up. Took him for an ultrasound and X-ray. The reports showed that he had diffuse parenchymal disease in both kidneys. Both his lungs showed signs of infection. His prostate is really enlarged. His hemoglobin really low. He is already on medications for his heart, prostate, hypertension, diabetes and constipation. Though he is receiving medicines for all the above conditions which have actually shown to be slightly effective but he is obstinately REFUSING TO EAT ANYTHING AT ALL. If we are lucky inspite of this multiorgan diseases he may live with effective medations but how when he is not eating. Please tell me how to make him eat when he is also refusing i.v. fluid adminstration and feeding tube placement. Please tell how to make him eat.
