Is someone who suffers from excessive flatulence during prayer, which drives him to spend a long time in the restroom before each prayer, and sometimes causes him to lose his devotion or make a sound due to suppressing the flatulence, considered among those with excuses? And must he use the restroom before every prayer, even if his suffering is sometimes psychological?

What you are suffering from is obsessive-compulsive disorder (waswasah), and we advise you to continue treatment and strive against yourself to abandon these obsessions and disregard them. Your feeling of needing to relieve yourself during prayer is an illusion and a deception from Satan, so ignore it and do not go to relieve yourself unless there is a genuine need, then promptly return. Begin your prayer normally and do not pay attention to the illusions cast by Satan. The feeling of needing to pass wind should not prevent you from praying. Do not exit the prayer unless you are absolutely certain that something has come out of you. If that happens, then exit, appoint a successor if you are an imam, then re-perform ablution and resume prayer. You are not considered among those with excuses as long as you find sufficient time to pray with proper purification. We advise you to consult trustworthy doctors and continue with treatment.
