Stools are supposed to be in a semi-solid form when it is excreted. If it is harder to pass because it has hardened, it is known as constipation. If it is in a more liquid form, it is considered to be diarrhea. Diarrhea is usually the result of either low dietary fiber intake or a low level of bacteria in the intestines to digest food properly. Sometimes, you just need to give your digestive system a break and this will rid it of allergens that the stomach might be ingesting.
Dietary fiber can be found in hard to digest fibrous material like legumes, plant shoots and some leafy greens. Dietary fiber usually is not digested by the gut and is excreted but what these fibrous material do is that the can form a fecal transport structure aiding excretion. Since these materials also hold water very well, they also make excretion easier. Dietary fiber in plant form is usually the stalks and shoots of plant that contain cellulose structures. These require specialized bacteria to be digested and disposed of, which humans have done away with in the course of evolution. However, many of these bacteria exist in pure herbivores but even they take a long time to digest these, having to regurgitate and break it down often. This brings us to the other aspect of watery stools – bacteria. We need bacteria in our intestines to further aid in digestion. In the normal digestive process, stomach acids and an enzyme called pepsin break down food at the first level. Then other enzymes act on food but the final act is usually performed by bacteria like lactobacilli in our intestines that breakdown materials like polysaccharides, which are complex sugars, into simpler sugars that are easily absorbed from the intestines to the blood stream. Sometimes, after an infection, or after a dose of antibiotics, the levels of intestinal bacteria fall as antibiotics and the body’s immune system can decimate populations of good and bad bacteria. It then takes time for the bacterial populations to recover and in the meantime, if another harmful bacterium takes hold, then the new variant has to be removed before the balance is restored. Diarrhea is also the product of amoeba infections that can be the result of ingesting contaminated food and water. This requires medical help.
Rectifying the situation requires one to eat simpler foods with a lot of fiber like whole wheat bread and bran on a daily basis. In addition, consuming a lot of probiotic yoghurt is also crucial. Probiotic yogurt contains live bacteria in it that repopulate depleted colonies in your gut.
