there is no term called prodial diarrhea. It may be periodic or persistent diarrhoea . There is usually no relation between acute diarrhoea and anosmia. But it may be due to dehydration or weakness or  due to reducing substance in stool (stool becomes explosive and noisy) or lactose intolerance or indiscriminate use of antibiotics or aggregative or adherent type of E. coli. You can use lactose free or monosaccharides based diet and healthy foods.
