Frequent loose motion with gas formation. The problem persists since last 20 years with interim relief for 10 years between 2006 to 2016 but since 2016 exercising extreme precautions in eating spicy/heavy/ outside food stopped milk completely stopped in order to avoid loose motion. Some foods triggers motion & there is constant fear in the mind of loose motion and hence avoid taking milk & foods which leads to gas formation & loose motion. Frequently visited doctors but no major relief but gets temporary relief on taking antibiotics followed by interim relief for couple of months. Please suggest long term course of treatment or medicine and diet.
