Ivanna González Carrasco, MD
Internal Medicine — Integrative Digestive Health and Autoimmune Thyroid · Kairos Longevity Clinic
Integrative internal medicine for SIBO, IBS, Hashimoto's, microbiota, and gut-thyroid questions
About
Ivanna González Carrasco, MD is the internal medicine specialist at Kairos Longevity Clinic. She completed her five-year Internal Medicine residency at Hospital Clínico San Carlos in Madrid (2017-2022), then built an integrative practice focused on digestive and autoimmune-thyroid problems in women. Her public work centers on the gut-thyroid axis, including SIBO, IBS, food intolerances, microbiota imbalance, and Hashimoto's hypothyroidism. She is registered with the Madrid medical college (No. 282875539).
What to Know
Signature approach
González brings conventional internal medicine training into a longer, systems-oriented consult. For digestive cases, she works through SIBO, IBS, food intolerances, reflux, constipation, and microbiota balance; for thyroid cases, she looks at the gut-immune-thyroid loop around Hashimoto's. Treatment can combine standard medical management with nutrition, lifestyle medicine, phytotherapy, and targeted supplementation.
What sets them apart
- Hospital-trained internist. Her five-year MIR at Hospital Clínico San Carlos gives her a conventional internal-medicine base before the integrative layer.
- Gut-thyroid specialization. She treats digestive symptoms and autoimmune thyroid disease as connected systems, a clearer focus than general wellness or generic functional medicine.
- Patient education presence. Her personal site, Instagram, newsletter, and lifestyle-medicine workshops make her one of Kairos's more publicly documented clinical educators.
Before You Book
- Care focus. Her Kairos consults center on internal medicine, digestive health, SIBO, IBS, microbiota, and Hashimoto's. Gynecology, sleep, aesthetics, and nutrition each have separate Kairos clinicians.
- Visit channel. Kairos is her in-person Madrid venue; her personal brand also offers online integrative consults outside the Kairos relationship.
- Language. Public materials are Spanish-first, so assume Spanish unless the clinic confirms otherwise.
- Self-pay setting. Kairos care operates outside standard insurance coverage.
