Loose Stool - Causes, Treatment

Loose Stool

Normal stool is soft, firm, and brownish in color with a peanut butter like consistency that prevents any strain or pressure during bowel movements. Any change in this texture, color, and consistency of feces is regarded as anomalous and loose stool is one of them. Loose stool can occur due to minor causes or severe underlying conditions.

Normal bowel movement has about 70 percent water. Any increase in the water content is abnormal. Even though diarrhea is a condition marked by loose yellow stool, all instances of loose feces cannot be termed as diarrhea. A diagnosis of diarrhea can only be made if a person experiences more than 3 instances of loose watery stool in a single day.

  • Drinking fluids does not worsen diarrhea; in fact intake of fluids helps decrease the frequency of loose stools as well as recover the electrolytes that are lost due to diarrhea. Drink fluids like ginger tea or cinnamon tea, soups, broth, soy or rice milk, and fruit or vegetable juices.
    • Drinking fluids can also help prevent dehydration, especially if infants are affected by loose stools. Lost salts can also be replenished with electrolyte solutions if watery bowel movements are frequent.
