Post treatment for Paranoid schizophreni

Hi, We undergone treatment for paranoid schizophrenia. And. We received good results post treatment. Now my mom is taking medications nicely, and we are happy too. Still i do have some concerns:- 1. My mom's activeness is drastically reduced. 2. Her physical movements got slow. 3. Also her tummy is getting larger. We totally trust our practitioner as he says let the course takes its own time. As per his due course, From August 2019 to as of now the medicines have been reduced from 9 to 3 in morning/evening and we really do appreciate his treatment. I have conveyed my above concerned to him too, he agreed that too because of water creation in the body due to medicines.So suggested to excercise little. But I am not able to understand in how much time  she will be active like before and what to do for remove the side effects of medicines.
