my friend just had a major surgery
Hi, Thanks for writing in. It is possible that your friend was given a lot of medicines during and after the surgery for removal of lung cancer and this has cause temporary loss of taste sensation. Surgery for lung cancer itself will not can any abnormal taste perception. However, the surgery is a major procedure and recovery takes time, and he will feel weakness for some weeks. Since he is also having kidney infection therefore he requires being under antibiotics for quick recovery. The loss of taste is a temporary problem, and he might request for extra seasoning in his diet. He should have daily 2200 kcal diet including good proteins and vitamins. Please do not worry.
