My sister has IBS-C. Can hydration and exercise help?

Question

Hello doctor,

I have a younger sister who is 24 years old, and she is suffering from IBS-C. She uses Isabgol fibers at night, and sometimes it makes her feel bloated and gassy. Moreover, her physician suggested that she needs to drink more water and do some exercise on a daily basis. Hence, we are interested in knowing:

Can fiber supplements ever worsen the symptoms of IBS-C patients, as opposed to alleviating them?
Does it really make a difference in bowel movements through lifestyle changes?

Kindly suggest.

Hello,

Welcome to icliniq.com.

I understand your concern.

The case of your sister is rather common among irritable bowel syndrome- constipation (IBS-C). The use of fiber products, including Isabgol, is commonly suggested because it draws water into the intestines and makes the stool softer.

At the same time, fiber does not always bring the expected results to every patient. When taken initially in large quantities or abruptly increased, the fiber may cause additional production of gases, bloating, and abdominal pain, as the gut in IBS is much more sensitive.

This is why the treatment begins with smaller dosages and gradual increase, making sure to have enough liquid.

Moreover, it should be noted that not every fiber works similarly. As a rule, soluble fiber (psyllium) is preferable compared to insoluble fiber (wheat bran), which may exacerbate bloating in IBS patients. There are some life hacks that could make a certain impact on IBS.

Firstly, it is essential to drink plenty of water to support the action of fiber and prevent constipation. Also, regular physical activity, even something as mild as walking, will stimulate the natural contractions of the intestines. Finally, regular meal times without holding the urge to defecate are significant.

Sometimes medication will be required if the above two factors prove insufficient. This can include stool softeners like Polyethylene glycol or other drugs to enhance bowel movement.

For the majority of patients with IBS-C, the most effective treatment is a combination of a gradually increasing amount of fiber consumption, hydration, physical activity, and possibly medication.

A proper dosage of fiber helps minimize bloating, while at the same time regulating bowel movements.

I hope this helps.

Thank you.
