Hello, We understand the condition and we appreciate your concern. But since you have told that your relative has undergone a surgery but you dis nit mention what surgery he had undergone. Not a problem with that. Generally if a person has undergone any sort of surgery will take time of 1 month to recover depending on the the surgery he has undergone. Just do nit worry about it. Because this is the t i.une he need to have better nutrition than ever. Consult s dietician for your help. Thank you
