Integrative Functional Medicine
Why this patient, by this route, now.
Conventional medicine asks what is the diagnosis. Integrative functional medicine asks why here, why now, why this way. It does not replace — it adds.
The Approach
Integrative functional medicine is neither alternative nor opposed to conventional medicine. It is conventional medicine practiced with a different visit length — 60 to 90 minutes — systemic listening, labs that go beyond the minimum, and a plan written in language that fits the patient's life.
The logic is a cascade. First, habit — sleep, light exposure, food, movement, connection. Then supplementation guided by labs — no guesswork, no commercial bundles. Then medication, when the signal asks and habit is not enough. Procedures and surgery, when clearly indicated. The order matters because inverting it costs more and delivers less.
Dr. Getúlio Amaral Filho holds primary board certification in nephrology and internal medicine (RQE 16.038), and postgraduate training in integrative functional medicine through ABMFI. Functional does not replace the specialty — it adds. That is why Continuum Plenya has a multidisciplinary team: physician, nutritionist, psychologist, and exercise physiologist, each with their own reading of the same patient.
Everything we recommend passes through published evidence. There are no esoteric therapies, no unregistered tools, no out-of-scope work. What differentiates is time, depth, and judgment — not exotic instruments.
Perguntas frequentes
Frequently asked questions about integrative functional medicine.
- It is a clinical approach that begins with the question "why this patient, by this route, now?" — not just "what is the name of this condition?" It treats systems (digestive, hormonal, mitochondrial, immune) as a coupled network, integrates habit, exposure, and laboratory data, and proposes intervention in a cascade: habit before supplement, supplement before medication, medication before procedure.
- It does not replace — it integrates. Conventional medicine is irreplaceable for diagnosing established disease and acute treatment. Integrative functional medicine works before (primary prevention), in between (functional causes that don't fit a traditional diagnosis), and after (metabolic follow-up for those already ill). The practical difference: visit length, depth of history, labs ordered, and the language of the plan.
- No. It is conventional medicine practiced with more time, more listening, more systemic reading, and more judgment in recommending habit, supplementation, and medication. Everything we recommend passes through published evidence. There are no esoteric therapies or anything outside the scope of the Brazilian Federal Council of Medicine (CFM).
- Dr. Getúlio's training in integrative functional medicine is through ABMFI (Brazilian Academy of Integrative Functional Medicine) — an institution that follows international standards and requires prior medical training plus a CFM-recognized specialty. Functional does not replace the specialty; it adds to it. Dr. Getúlio holds primary board certification in nephrology (RQE 16.038) and internal medicine.
- Metabolic syndrome and pre-diabetes in a reversible phase, chronic fatigue with no obvious cause, sleep and circadian rhythm disorders, hormonal changes in men (testosterone) and women (peri- and post-menopause), functional digestive symptoms, subclinical nutritional deficiencies, chronic pain related to low-grade systemic inflammation. Always as a complement to managing the underlying disease, never as a substitute.
- Depends on the target. Sleep, energy, and digestive symptoms usually respond in 4 to 8 weeks. Metabolic markers (HbA1c, lipid profile) in 12 to 16 weeks. Body composition and VO₂ max in 16 to 24 weeks. Everything is measured at scheduled re-evaluation — without re-evaluation, there is no functional medicine, there is marketing.

Solidão como fator de risco cardiovascular: o dado que falta na consulta
A meta-análise de Holt-Lunstad mostrou que vínculos sociais frágeis aumentam mortalidade tanto quanto fumar. A American Heart Association assumiu o ponto em 2022. E quase nenhuma consulta cardiológica pergunta sobre isso.

Os quatro assassinos silenciosos que se instalam depois dos 40
Cardiovascular, metabólico, oncológico, neurodegenerativo. Quatro doenças respondem pela vasta maioria das mortes prematuras em adultos. E nenhuma aparece de repente. Cada uma tem uma janela de 10 a 20 anos silenciosa, com biomarcadores antecipatórios. Não é catastrofismo. É mapa.

Pré-diabetes não é uma fase. É uma janela de cinco anos.
HbA1c entre 5,7% e 6,4% costuma ser tratada como aviso vago: "vamos repetir em um ano". Em nossa prática clínica, observamos o oposto: cada ano sem ação aumenta a probabilidade de progressão e estreita a janela em que reverter ainda é o cenário mais provável.
