You've already been through five doctors. Not one ordered the right test.

Almost every patient of mine arrives like this. It's not a shortage of doctors. It's the shortage of a doctor who looks at you as a whole.

I went through dozens of doctors too. I lost years too. I also thought it was my fault. I learned, the hard way, why it wasn't working.

My Journey

I Was My First Patient

I was the doctor who couldn't heal himself.

160 kg (352 lb). Chronic insomnia. Binge eating. Anxiety that paralyzed me. I didn't sleep. I ate to stay awake. I worked so I wouldn't have to think. I was doing everything mass medicine teaches: sacrifice, effort, total dedication. And my body was screaming back.

I looked for help the way everyone does. I went through four Brazilian states looking for answers. Nutrition physicians. Endocrinologists. Bariatric surgeons. Psychiatrists. Dozens of dietitians. Each one treated a piece. No one saw the whole.

And I kept going. Night shifts. Public clinics. It was all I knew: give everything. Until the morning that changed everything.

I was on my third night without sleep, napping 5 minutes between patients. I broke into a cold sweat. Racing heart. Arrhythmia.

I saw my last patient, went to the on-call room, and thought I was going to die right there.

Three colleagues had suffered heart attacks in that same hospital, that same year. One of them died.

In that on-call room, alone, I understood: the next one could be me.

It was there, as a doctor, that I had to admit something that still hurts to say:

"If healing others means getting sicker myself, then the model is wrong."

I stopped. I studied from scratch. I connected what no one was connecting: gut, hormones, sleep, mind. I treated it as a system, not as loose parts. I became my own first evidence.

I lost 55 kg (121 lb). I got my sleep back. The anxiety left. I came back to life.

The Method

Root-Cause Medicine · the Reactiva Method

Root-cause medicine that integrates anxiety, sleep, hormones and nutrition as one single system, from the gut to the mind.

That's why I don't do one-off appointments. Root cause demands ongoing care. Thirty minutes cure no one.

If I, giving my absolute best inside mass medicine, took years to find the answer. How much longer are you willing to keep searching?

Identities Protected

The Cases You Will Not See On Any Other Site.

My patients do not become marketing material. I respect the people who trust me with their own bodies. But I can tell you what happened. No name. No face. With the result.

Woman · 47

Senior executive

Hadn't slept in 4 years. Zero libido. 14 kg (31 lb) over. Marriage on the edge of divorce. Five doctors before me. None had ordered the right test.

When the right test showed up, everything changed. 8 months later: sleeping deeply, marriage standing, back in command of her company.

Businessman · 52

Partner in three companies

He was losing his decision-making to exhaustion. Bariatric surgery recommended. He refused. Antidepressant prescribed. He refused. Five doctors. No one looked where they needed to.

One small adjustment made all the difference. 8 months later: back in command, -50 kg (-110 lb), opened his fourth company.

Woman · 38

Law firm partner

Regained everything two years after bariatric surgery. Ate "right". Trained 5x a week. Went nowhere. Five doctors. No one investigated the whole picture.

The test no one had ordered changed the protocol. 18 months later: -50 kg (-110 lb) sustained. No yo-yo effect.

Each of these cases went through 5 to 11 doctors on average before getting here. The problem was never a shortage of doctors. It was the shortage of someone who looked at the whole system.

Investigation, Not Guesswork

"I've Already Done Every Test, Doctor."

It's the most common sentence I hear on day one. And it's an innocent lie, because no one has done the tests that matter.

Most doctors order 4 or 5 basic items. I order between 15 and 25. It's not overkill. It's the minimum for someone to look at you as a whole.

How does your body handle sugar?

Most doctors only order glucose. But the problem shows up much earlier: in insulin and A1C.

Glucose · Fasting insulin · Hemoglobin A1C

Is your thyroid converting properly?

It's not enough to know if it's high or low. You have to see how it turns hormone into usable energy.

TSH · Free T4 · T3 · Reverse T3

Are your sex hormones balanced?

The total level isn't the whole story. What matters is the free fraction, what's binding, and what's left over.

FSH · LH · Total and free testosterone · Estradiol · SHBG

How does your body respond to stress?

Cortisol is not "bad". The problem is when it runs high at night, when it should be low.

ACTH · Salivary cortisol (not just serum)

Does your body have the right fuel?

Vitamin D on the floor, low B12, inadequate iron. It explains chronic fatigue no one investigates.

Vitamin D · B12 · Ferritin · Homocysteine

Can your liver and kidneys handle it?

Not to "diagnose disease". To understand how much protocol your body can take.

Creatinine · Urea · AST · ALT · GGT

Most doctors don't order half of this.

I always do.

What happens when no one looks

Patient, 27 years old. Severe depression. He had already been through a psychiatrist, a general practitioner, an endocrinologist. Antidepressants, adjustments, more antidepressants. Nothing.

No one ordered total and free testosterone. Because "he's too young to have a hormonal problem".

I did. Total: 27. Lower than a healthy woman's. Alongside it: B12 near the bottom. Iron on the floor.

It wasn't treatment-resistant depression. It was a body screaming for nutrients and hormone. And no one was listening.

The Methodology

The Reactiva Method

I don't treat isolated symptoms. The Reactiva Method integrates 4 fundamental pillars working in synergy for results that last.

1

Anxiety

Mind

I treat the root of binge eating, chronic stress and the emotional imbalance that sabotages any diet or training plan.

Benefits:

  • Binge eating under control
  • A mind at peace
  • Clarity to decide
2

Sleep

Recovery

Without quality sleep nothing works: not diet, not hormones, not training. I rebuild the cycle from scratch.

Benefits:

  • Deep sleep
  • Energy all day
  • Real recovery
3

Hormones

Metabolism

Thyroid, cortisol, testosterone, insulin. The body's engine. If it isn't running right, nothing from the outside fixes it.

Benefits:

  • Metabolism awake
  • Real body composition
  • Drive and energy
4

Vitamins

Nutrition

Vitamins and minerals in the exact dose for your case, based on lab work. Not on a guess at the pharmacy counter.

Benefits:

  • Energy that lasts
  • Strong immunity
  • Real longevity

The Difference

These 4 Pillars Do Not Work In Isolation

Your gut produces 90% of your serotonin, the well-being hormone. When gut health is compromised, anxiety and binge eating show up.

Chronic anxiety raises cortisol, which disrupts insulin and thyroid, locking weight loss even with a perfect diet.

Unbalanced hormones destroy sleep quality. Without deep sleep, there is no recovery, energy or focus.

The Reactiva Method breaks this cycle: it treats all four fronts at the same time, because that is the only way things truly change.

Access By Curation

How I Work

Direct access

My personal WhatsApp is exclusive to patients under ongoing care and mentees.

First contact

We listen to you, understand the case and decide whether ongoing care makes sense.

Personal curation

Few patients. Small roster, big results. No volume, so attention stays dedicated.

Continuous support

You are not alone between one conversation and the next. Real ongoing care means being available when the patient needs it.

I care for few so I can care well. That's why there isn't always an opening.

An isolated appointment cures no one. The doctor sees a symptom, prescribes, disappears. And the patient comes back months later with the same problem. I don't make that mistake with my patients.

Ongoing Care. Not Appointments.

This Is the Model I Built. And the Model I Teach.

Everything you read on this page came from one decision: stop selling appointments and start delivering results. If you are a physician, this model can be yours too.

"If healing others means getting sicker myself, then the model is wrong."

Patient care is provided in Portuguese. Openings by application and curation.

Frequently Asked Questions

Before You Reach Out

Straight answers to the most common questions.

Because I was seen by dozens of doctors before I healed. Each one gave me thirty minutes, prescribed, disappeared. I kept getting sicker. When I turned the method upside down and healed myself, I swore: I will never do to a patient of mine what was done to me. I don't do appointments. Because appointments didn't cure me. And they won't cure you either.

I carry a small number of patients. That is how I deliver what I deliver. New openings appear only when current patients stabilize. You apply through the form. My team reviews it and reaches out to schedule a conversation with me. Care is provided in Portuguese, 100% online, wherever you live.

No. Insurance limits appointment time, doesn't allow real ongoing care and excludes critical lab work. Serious ongoing care doesn't fit that model. I work exclusively private.

It's for those who have been through enough doctors to suspect the problem isn't a lack of medication. It's the lack of someone who looks at the whole. For those who want root cause, not shortcuts. For those who accept that real transformation takes time. If you are looking for a quick fix, we are not compatible.

Investment details are discussed in the conversation, after my team understands your case. Serious ongoing care is not a commodity with a price list. It's an informed decision. The path starts with the application.
