Your symptoms are more likely related to a combination of medication effect (paliperidone), low dopamine/mental fatigue, and metabolic factors rather than a primary stomach disorder. Apathy, reduced motivation, and attention-skipping are well-known side effects of antipsychotics and can mimic or worsen ADHD-like symptoms. The temporary improvement after eating and cardio suggests a dopamine and glucose-related boost, not a gastrointestinal disease.
Next Steps
Discuss these symptoms with your psychiatrist—dose adjustment or switching medication may be needed if apathy is affecting daily functioning. Basic blood tests such as
fasting blood sugar,
HbA1c,
thyroid profile,
vitamin B12,
vitamin D, and
lipid profile can help rule out metabolic contributors.
Health Tips
Do not stop or alter paliperidone on your own. Long gaps between meals can worsen mental dullness and attention issues. Regular cardio improves brain dopamine and motivation—try 20–30 minutes daily. I
