Your labs came back normal. Your energy didn't.

I care for people who run everything out there and lost command of their own body. Sleep, weight, energy, focus and hormones, read as one single system.

I was that patient. I went through dozens of doctors' offices until I understood that no one was looking at the whole system.

My clinical focus: studying how hormones, medications, vitamins and minerals interact in one body, and turning that individual study into one plan per person.

I don't do one-off appointments: even the first appointment is already the first stage of ongoing care. Entry by application, with few openings. Patient care is provided in Portuguese.

My Journey

I Was My First Patient

I was the doctor who couldn't take care of himself.

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

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, whatever came up. Until the night that changed everything.

I was working in two small towns. I finished a shift in Coelho Neto and chained another 24 hours in Duque Bacelar, a town of 10,000 people, in a hospital with no defibrillator. It was my third night without sleep.

I broke into a cold sweat. My heart was racing, out of rhythm. I saw my last patient and went to the on-call room. I couldn't leave: I was the only doctor there. I lay down thinking I was going to die right there.

That year, three colleagues had suffered heart attacks in Coelho Neto, where the defibrillator was broken. One of them died. His son studied medicine with me.

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

It was there 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. My own body was the first case.

I lost 55 kg (121 lb). I sleep through the night again. Anxiety stopped running my life. 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, and thirty minutes can't cover a whole system.

I'm a doctor, and it still took me years to find the answer. You don't have to walk that road alone.

Identities Protected

Three Patients. No Names, No Faces.

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, with no name and no face.

Woman · 47

Senior executive

Four years without a full night of sleep. Libido at zero, 14 kilos (31 lb) too many and a marriage hanging by a thread. She had already been through five doctors' offices and left each one with a different prescription.

Once sleep, hormones and stress started being treated together, the nights came back first. Eight months into ongoing care, she was sleeping through the night, the marriage was still standing and she was back in command of her company.

Businessman · 52

Partner in three companies

He was making bad decisions out of sheer exhaustion. He was told the way out was bariatric surgery and said no. He was told it was depression and said no to the antidepressant. No one had looked at sleep, insulin and hormones together.

The plan dealt with what no one had dealt with. Eight months later, he was back in command, had lost the weight he'd carried for years and had opened his fourth company.

Woman · 38

Law firm partner

Two years after bariatric surgery, she had regained all the weight. She ate right, trained five times a week and the scale wouldn't move. The answer she kept hearing was always the same: lack of discipline.

Discipline she had plenty of. What was missing was investigating the whole system. With the plan adjusted to what her body showed, she lost the weight again and, a year and a half later, it has stayed off.

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 almost always only half true, because no one ordered 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 keeping the right pace?

One TSH inside the range is not enough. The number is read together with the symptoms, and T3 comes in when the picture calls for it.

TSH · Free T4 · Antibodies · T3 in selected cases

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.

Late-night salivary cortisol · ACTH when indicated

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

A routine check-up doesn't order half of this.

I order what your case calls for.

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 testosterone: 27, far below the minimum expected for a man his age. Alongside it: B12 near the bottom. Iron on the floor.

Before calling it treatment-resistant depression, someone had to look at the body: nutrients and hormone on the floor. No one had looked.

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 right dose for your case, based on your labs. Not on a guess at the pharmacy counter.

Benefits:

  • Corrects what the labs showed
  • No supplements in the dark
  • Periodic re-evaluation

The Difference

These 4 Pillars Do Not Work In Isolation

A large share of the body's serotonin is made in the gut, and gut and brain talk to each other constantly. When the gut is inflamed, mood, appetite and sleep tend to feel it too.

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.

From the Gut to the Mind • From Root Cause to the Plan

Access By Curation

How I Work

Direct channel

Patients in ongoing care talk directly with my team day to day, and I step in whenever the case calls for it.

First contact

My team reads your application, understands the case and calls you for a conversation if it makes sense. The first appointment is already the first stage of ongoing care.

Personal curation

Few patients, on purpose. Without volume, I can really get to know each one.

Continuous support

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

I take on few patients. That's why there isn't always an opening.

In a one-off appointment, the doctor sees the symptom, prescribes and disappears. Months later the patient is back with the same problem. In ongoing care, we adjust together until the system is back on track.

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 one-off appointments and start providing ongoing care. 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. I don't do one-off appointments: even the first appointment is already the first stage of ongoing care. Openings by application.

Frequently Asked Questions

Before You Reach Out

Straight answers to the most common questions.

Because I went through dozens of doctors before I got better. Each one gave me thirty minutes, prescribed and disappeared, and I kept getting sicker. When I started treating the body as a system, everything changed, and I swore I would never do to a patient of mine what was done to me. That's why I don't do one-off appointments: even the first appointment is already the first stage of ongoing care.
