What to Do About Loose Stools From IBS

Avoid Food and Drink That Can Contribute to Loose Stools

The following foods have a reputation for softening stool. Since none of them are essential for health, feel free to delete them from your diet.

• Sugar-free foods and chewing gums with artificial sweeteners that end in "ol"
• Caffeine-containing drinks (coffee, soda, tea)

Don't Eat Too Many Fruits at the Same Time

Fruits are a wonderful source of nutrients, such as vitamins, minerals, and antioxidants. However, they also contain fructose and our bodies have a limited ability to absorb too much fructose at the same time. Too much fruit, too soon, means that excess fructose makes its way into the large intestine where it can draw excessive water into itself contributing to the looseness of your stools.

Don't Take OTC Products Containing Magnesium

Magnesium has a well-established reputation for acting as a laxative. In fact, it is a primary ingredient in most prep formulations for colonoscopies.

Be careful that you are not taking in higher amounts of stool-loosening magnesium from an over-the-counter product without knowing. The following may include magnesium so read labels carefully:

• Antacids
• Multivitamins
• Other vitamin formulations

Consider Probiotics

Probiotics are bacterial strains that are thought to be beneficial to our digestive tracts. There is evidence that they promote a more favorable balance of your gut bacteria.

This beneficial effect on the bacteria within your intestines may help your body to establish improved motility and result in less intestinal gas, both of which can serve to slow down the fast speed of intestinal contractions that ​contribute to loose stools.

You can increase your intake of probiotics through probiotic supplement formulations. You may also find eating a diet rich in fiber, fruits, and vegetables, as well as fermented foods such as yogurt, sauerkraut, tempeh, kimchi, miso, and kombucha can help you avoid purchasing expensive over-the-counter probiotic formulations.

Ask Your Doctor About Fiber Supplements

Although typically recommended to ease constipation, fiber supplements (also known as bulk laxatives) draw water into the stool, helping to firm it up. Here are some choices:​

• Psyllium (Fiberall, Genfiber, Konsyl, Metamucil)
• Calcium polycarbophil (Fibercon, Equalactin)
• Methylcellulose (Citrucel)

Manage Your Stress

Stress has long been known to speed up intestinal movement due to the body's natural stress response. Reducing stress can help your body to establish a better rhythm, retaining stool longer to allow it to be firmed up as water is drawn out. Whenever possible, try to reduce the amount of stress in your life by avoiding demanding situations or individuals. When this is not possible, be sure to engage in activities that offset the effect that stress has on your body. Here are a few to consider:

• Meditation
• Relaxation exercises
• Tai Chi
• Yoga

Other Causes of Loose Stools

If you haven't been diagnosed with IBS, there can be many other causes of loose stools. As you try to figure out what might be going wrong, and to make sure that you give your doctor information that will be helpful for a correct diagnosis, ask yourself the following questions:

• Any recent changes in the way you eat?
• Are you on a new medication?
• Has your water source changed, exposing you to different types of bacteria?
• Have you recently traveled?
• Have you recently experienced food poisoning or some other intestinal illness?
• Has your stress level been higher than usual?
