Dra. Maria Eduarda Mattos
About the specialist

Cutting-edge science,
a whole-person view.

Medical degree, postgraduate training in Gastroenterology and specialization in Digestive Motility at Hospital Israelita Albert Einstein, São Paulo. Dr. Maria Eduarda Mattos dedicates her practice to a field still rarely explored in depth in Brazil: digestive motility and neurogastroenterology.

Her path began in Family and Community Medicine. That foundation shaped a doctor who sees the whole person, not only the symptom. Today, the same attention supports a practice of very high technical precision at the Clínica do Aparelho Digestivo (CAD), in Rio Verde.

Scientific evidence and genuine care, without giving up either.

Real stories

What changes when the right
cause is found.

Dra. Maria Eduarda Mattos
“
Doctor, I had been suffering with this for years. I lost more than 30 kilos. Doctors said it was reflux and I was even getting ready for reflux surgery. But, thank God, someone referred me to you. At the consultation you said something did not add up and you did the manometry. After the treatment and the right surgery, my life changed completely. Today I can eat everything again, without fear and without pain. I have lunch with my family again. I am already eating rice, beans, ground beef. I am very grateful to you, Dr. Maria Eduarda, for not giving up on me. You changed my life and my family's.

Dr. Maria, I suffered for many years with constipation. I thought it was normal to live like that. I went days without a bowel movement and felt a lot of pain. I stopped travelling with my husband because of my bowels. Today my life is different.
