Precision Psychiatry: Why Treating Diagnoses Instead of People Is Failing Mental Healthcare with Dr Sonia Diaz
Send us Fan Mail [https://www.buzzsprout.com/2489689/fan_mail/new]
Most mental health care is built for speed, not understanding and patients feel it. When appointments are short and the plan is mostly symptom management, even smart, motivated people can end up “stable” but nowhere near well. We sit down with psychiatrist and healthcare innovator Dr Sonia Diaz, founder and medical director of Wellmivia Medical, to talk about what changes when you stop treating diagnoses like destinations and start treating the whole person.
We dig into precision psychiatry and metabolic psychiatry, including why blood sugar swings can destabilise mood, how thyroid dysfunction can look like depression or anxiety, and why hormonal health such as testosterone may sit quietly behind fatigue, low drive, and poor sleep. Dr Diaz also explains how pharmacogenetics and pharmacogenomics can guide medication choices, not as a gimmick, but as a way to reduce trial-and-error and tailor treatment to real biology and real life.
You will also hear the practical side of building a modern practice: direct pay and concierge psychiatry, a 90-minute evaluation model, what patients actually value most (time, trust, and direct access), and why some premium telehealth platforms deliver slick experiences without better outcomes. We finish with a grounded look at AI in healthcare, where it helps, where it does not, and how smart documentation tools can restore human connection instead of replacing it.
