For millions of people navigating the traditional healthcare system, a familiar cycle plays out: A patient wrestling with stubborn weight gain, disrupted sleep, mood changes, and low libido visits their clinician hoping for answers. Yet after standard laboratory testing and a routine physical, the verdict often comes back: Your labs and vitals are normal. Patients who still feel unwell can leave feeling overlooked and stranded.

“The problem with healthcare right now, number one, is that it’s just really disease care, right? We wait till you get diagnosed to give you something,” said Darshan Shah, MD, surgeon and longevity physician and founder and CEO of West Hollywood, California-based NextHealth.

A growing number of consumers, including those with obesity and overlapping conditions, are seeking proactive, “longevity”-oriented care outside the traditional healthcare system. Future Market Insights valued the global longevity clinic chain infrastructure market at $2.6 billion in 2026 and projected that it would reach $6.9 billion over the next decade.

This expanding market encompasses a broad range of practices. Some offer patients more time and individualized preventive care, whereas others are cash-pay operations offering costly interventions with limited evidence.

For mainstream and obesity-focused clinicians, this shift represents both a warning and an opportunity. How can physicians address complex chronic complaints with evidence-based rigor while helping patients navigate the rapidly expanding wellness market?

Looking Beyond ‘Normal’ Labs

Routine laboratory testing can identify established disease and important risk factors, but normal results do not necessarily explain the symptoms that brought a patient to the clinic. 

Neil Panchal, MD, chief medical officer and co-founder of New York City-based Longevitix, said fragmentation of care can make it difficult to recognize trends over time.

“An A1c from the annual physical, a basic metabolic panel from urgent care, a lipid panel from cardiology, and a symptom the patient mentioned to none of us, all are sitting in different systems,” Panchal said. “Cardiovascular-kidney-metabolic syndrome does not announce itself in any one of those. It shows up in the drift between them, across years, when the panels can finally be read side by side.”

Some longevity practitioners argue that conventional testing can also overlook potentially useful biomarkers. Mitch Ghen, DO, PhD, of Boca Raton, Florida-based Ghen Medical, pointed to inflammatory markers, cardiovascular markers beyond cholesterol, glycemic markers, hormones, full thyroid studies, minerals, and “the so-called ‘hormones of youth’ like DHEA [dehydroepiandrosterone] and pregnenolone.”

Others advocate greater use of imaging to look for abnormalities not evident on standard testing. Humberto Carrion, co-founder and CEO at Miami-based 3T Radiology & Research, said imaging can provide information about blood vessels and organs that laboratory testing cannot. 

“Cholesterol panels may come out completely fine, and all the while, soft plaque is just building up in the arteries. Liver enzymes may not show an issue while fatty infiltration is visible on our imaging,” Carrion said. “A woman in her mid-40s might come in experiencing brain fog and fatigue with clean lab results, yet have structural cardiac changes or bone loss that can’t be caught on a blood panel.”

Another limitation of routine testing is that some diseases may not be identified until values cross established diagnostic thresholds, said Doug Bertram, LAc, MTCM, founder and CEO of the orthopedic wellness brand Structural Elements based in Hagerstown, Maryland.

“Sleep gets lighter, recovery gets slower, the waistline creeps, joints stiffen, blood pressure edges up, and the nervous system starts running hot all day,” Bertram said. “The body shows dysregulation mechanically before it shows up chemically.”

To identify disease early and prevent its progression, some membership-based longevity clinics use more frequent testing. Shah said NextHealth members undergo quarterly blood testing along with strength, cardiovascular fitness, mobility, and balance assessments.

Teresa “Tami” Oberbroeckling, DFM, PA-C, founder and managing partner of Tampa Bay Total Wellness, based in Tampa, Florida, said a normal test result answers a specific clinical question but may not explain the full range of symptoms a patient is experiencing. 

“A visit focused on one complaint may miss the pattern across weight change, sleep, mood, medications, menstrual history, blood pressure, and metabolic risk,” she said. “A more comprehensive evaluation starts with a careful history and exam, then uses targeted testing. It may identify a treatable condition or a risk pattern.”

Meeting Demand Without Abandoning Evidence 

Rising demand for personalized care can put traditional physicians in a bind. Brief appointments may leave little time to explore multiple concerns, but dismissing patients’ questions about longevity and wellness treatments may push them toward unregulated wellness marketers offering expensive or unproven interventions.

Adam Nessim, MD, interventional spine and pain medicine physician whose practice, Westport Pain and Performance, is scheduled to open in Westport, Connecticut, next year, said simply dismissing questions about popular wellness treatments is seldom effective.

“The core of evidence-based longevity is unglamorous: sleep, strength, metabolic health, blood pressure,” Nessim said. “When patients ask about unverified trends, the strongest answer is specifics about what the evidence actually shows, which holds credibility in a way that a flat ‘no’ does not. That matters, because the patients most eager for better care and the newest approaches are also the ones most likely to get pulled in by snake oil salesmen.”

Betram likewise cautioned that individual therapies aimed at health optimization may not address underlying health problems.

“Putting rocket fuel in a Pinto won’t make it go faster. It might just cause a bigger explosion when it gets rear-ended,” Bertram said. “Superfoods and peptides are the rocket fuel. The frame, the alignment, the suspension, and the brakes are what actually determine whether that car survives the road.”

Kelly Brown, DO, medical director of Arizona-based Geviti Health and a family medicine physician with advanced training in hormone optimization and longevity medicine, likewise cautioned against equating personalized care with indiscriminate testing.

“Personalized care should not mean ordering every test available. Longevity medicine is most useful when it strengthens evidence-based prevention rather than replacing it with unproven interventions,” she said.

Oberbroeckling suggested a pragmatic framework: Ask patients what they most want to improve, identify conditions that would change management, explain the rationale behind each proposed test or treatment, and establish how improvement will be measured and when it will be reassessed.

Navigating the Longevity Landscape: The Good, the Bad, and the Intravenous Drip 

Private longevity clinics occupy a broad spectrum. Some emphasize established preventive measures and risk assessment; others sell high-margin, low-evidence therapies. 

“Their strength can be time: Patients may finally get space to tell the whole story and receive help carrying out a plan,” Oberbroeckling said. “The danger is turning that trust into an expensive sequence of tests, supplements, injections, or IV [intravenous] treatments without a clear indication, discussion of risks, or a way to judge benefit.”

Maintaining a nonjudgmental dialogue is particularly important when patients seek treatments elsewhere, she added.

“When patients seek care elsewhere, I want to know exactly what they are taking or receiving so I can discuss interactions, safety, and whether it is helping. Shaming a patient for exploring options makes that conversation less likely.”

Knowing When to Refer

Primary care and obesity-focused clinicians cannot manage every facet of complex longevity care alone. Nessim suggested three questions when deciding whether testing or treatment should remain in-house: “Can you explain the result to the patient? Does it change management? Can you follow it longitudinally? If any answer is no, refer.”

Oberbroeckling said referral is appropriate when symptoms suggest disease outside the clinician’s scope, a diagnosis remains uncertain after an appropriate evaluation, treatment requires expertise or monitoring the practice cannot provide, or care has become fragmented across multiple offices.

Once a referral is made, communication among clinicians remains essential to ensure that critical findings are addressed and responsibility for follow-up is clear.

Start by Hearing the Patient 

Ultimately, experts said the longevity boom’s appeal may have as much to do with the patient experience as with any particular test or treatment. Patients struggling with weight, metabolic changes, and perimenopausal shifts may simply want sufficient time to explain their experience and a clinician who takes their concerns seriously.

Nessim said that longer, unhurried longevity-related visits provide pacing to connect disparate symptoms rather than treating them in isolation. Bertram said clinicians can provide a similar environment by considering multiple complaints together rather than as unrelated problems.

“When a patient says they’re exhausted, their neck and back hurt, they wake at 3 AM, their digestion is off, and they’ve gained weight without changing anything, that isn’t five problems. That’s a system that has lost its ability to regulate, showing strain in five places.”

Oberbroeckling said that the process should begin before laboratory results are interpreted.

“Start by letting them describe what has changed and how it affects their life before interpreting the lab report. Reflect the concern back, ask what they fear has been missed, and explain the reasoning behind the next step,” she said. “Your results are reassuring so far, and I can see you still feel unwell’ is an honest place to begin.”

Her final recommendation gets to the central lesson physicians can take from the longevity boom.

“Validation is a commitment to investigate thoughtfully and follow through. It does not require agreeing that every symptom has one hormonal or metabolic cause.”
