29. Male. 5'6". 74 kg. Currently on paliperidone 100 mg monthly injections since June 2024, aripiprazole 5 mg daily. I have been having symptoms like apathy, anhedonia, brain fog, irritability, impulsivity. I also get head pressure that occurs with these psychiatric problems. I don't remember how long I have been experiencing these symptoms, but possibly it would be 3-4 years In January 2024 in last year I ate chinese noodles wraps, milkshake as evening snack and walked daily for a month. At last day of this routine I had resolution of these symptoms one evening. This effect lasted 2 hours before complaints returned. Can chinese food spices cause gut bacteria to heal and effect psychiatric and physical symptoms? Is gut health related to psychiatric problems in any way? Can SIBO cause this symptoms? Can post acute COVID-19 syndrome cause this symptoms?
