Irritable bowel syndrome

Irritable bowel syndrome is a functional disorder where abdominal pain is linked with changes in stool frequency or form. Standard evaluation does not show inflammation, tumor or another structural cause.

IBS may present with diarrhea, constipation, alternation of both, bloating, rumbling and sensitivity to stress, poor sleep, some carbohydrates and fatty food.

What Must Be Excluded

Blood in stool, nocturnal diarrhea, fever, anemia, weight loss, symptom onset after 50 or family history of bowel cancer require different evaluation, not an IBS label.

Keto And FODMAP

For some people, low-carb eating reduces fermentable carbohydrates and bloating. For others, symptoms worsen from too much fat, sweeteners, nuts, dairy or low fiber.

What Helps

A food and symptom diary, fiber adjustment, caution with polyols, sleep, movement, stress work and treating the constipation or diarrhea subtype can help.

Practical Conclusion

IBS does not mean symptoms are imaginary, but it is not treated by one universal diet. Food is adjusted to symptoms, and warning signs are checked separately.

How To Find Personal Triggers

It is better to change one factor at a time: polyols, onion, garlic, dairy, coffee, alcohol, nuts, fat volume or fiber. If everything is removed at once, the real trigger becomes unclear and the diet may become poor.
