Acute Postprandial Diarrhea 

Sudden episodes of diarrhea just after your meals is called acute PD. It can happen due to many reasons because a simple course of eating can make your large intestinal muscles move or contract in the direction of passing your stools. Moreover, if you have any ongoing trouble with your gut like an infection, Irritable Bowel Syndrome, food poisoning etc., these movements can get more painful, stronger and frequent followed by a feeling of urgency.

It will keep your body hydrated.

In the case of children, no medicines should be given without proper consultation with your doctor.

As we know that bile acids or juices are released by the gallbladder for digestion of fat. When the bile juices are not reabsorbed as expected, these tend to make large intestinal contractions stronger and more frequent leading to watery stools. As far as the causes behind BAD are concerned, those are kind of vague. In some cases, the causes are unknown, whereas in some cases, it could be any surgery or conditions associated with the digestive tract, especially small intestine, pancreas or gallbladder.

It is a condition wherein people suffering from it don’t produce enough amount of Lactase (an enzyme that breaks down lactose found in dairy products) as a result of which, they are unable to digest milk or milk products leading to diarrhea.

When a person is suffering from this condition, his or her stool is more likely to be found floating, not sinking. This ailment can be alarming. So, before its too late, please see to your doctor.

5. Malabsorption of sugar

Apart from lactose, sorbitol and fructose are two other kinds of sugar that some people find difficult to digest as a result of which they tend to defecate watery stools. The former is found in artificial sweeteners and certain fruit, whereas the latter is found in fruit and corn syrup.

6. Dumping syndrome

If you have recently gone under the knife for getting a bariatric surgery for losing weight, you are more likely to experience this issue. This health condition is also called rapid gastric emptying.
