    Final Thoughts

    While IBS shares symptoms with many digestive disorders, it is fundamentally different because it does not cause structural damage. Other conditions like IBD, infections, or cancer may require urgent and specific treatments.

    If symptoms are persistent or unusual, a proper medical evaluation is essential to identify the exact cause and ensure appropriate care.
