Bowel movements maybe once a week since I was a kid unless I take magnesium daily. Usually stool is on the diahrria side, occasionally white chuncks?

Weekly bowel. movements indicates a need to see a gastroenterologist, GI doctor. Slow transit time in the gut can leave us open to poor immune function. Magnesium helps. Maybe other minerals and nutrients are low also. Consider a Micronutrient Test like the one at Spectracell lab in Texas. Can be done through local professionals. Peace and good health.
