Everybody who returns home from a mission undergoes enhanced post-deployment screening three to six months afterwards. At that time, their mental health conditions in particular are reviewed, but they also have a chance to bring up physical health conditions. These could include side effects of medications or other concerns that individuals might have. That gives an opportunity to review those things. In addition, at any other time afterwards when they're having medical appointments and follow-up, people can bring up their concerns as well.
