<s>[INST] My brother has Hepa A and has been discharged lately from the hospital. He then went back to gym to do his weight lifting or gym exercise after a week. He uses whey protein shake. Is it alright to do this again? Is there any complications or effects on his liver if he will continue doing weight lifting and drinking this protein shake? [/INST] Dear Friend. Hepatitis A is transmitted by face oral route. If he has improved, his liver functions have settled, he can resume his gym. Ask him to carry his own water to gym. Regarding protein supplements, see excess of everything is bad. In relation to hepatitis A, he can consume high protein diet if he has recovered and has no encephalopathy that is disorientation, disturbance in consciousness which may occur during the course of hepatitis A infection, and during that period low protein diet is recommended. If he has recovered totally he can do his workouts and consume protein supplements in moderated qualities. Stay Healthy </s>
