What should I ask my doctor about gut health?

Dr. Rajan recommends being super data-driven when visiting your doctor. He emphasizes that it's crucial to bring up symptoms that have been troubling you for days, weeks, or months, regardless of how common they may seem. Keeping a symptom diary can help provide concrete data to your healthcare provider, ensuring that your concerns are taken seriously.

How is fiber linked to endometriosis?

Dr. Rajan discusses epidemiological data showing that higher fiber intake is associated with a lower risk of GI symptoms related to endometriosis.
