Hi, I understand your concern. Unformed stools are indicating indigestion. Increased fiber intake might be a cause. Another one is alteration in stool flora. Apart stool test, I advise to run examination of stool for ova/parasites, as sometimes intestinal worms can use indigestion. Try to eat slowly, chew up well and slowly do not rush as this cannot be digested by your stomach. Observe what foods are passing in the stool indigested, in order not to use them until fully recovered. Take probiotics to stabilize intestinal flora. Vegetable fibers are fibers derived by vegetables you consume. A diet high in fiber can cause loose motion too. Hope this helps.
