When a patient comes in exhausted, foggy, and struggling to feel like themselves, and every single lab result comes back within normal range, something has already gone wrong. Not with the patient. With the system. Dr. Angela Petersen, a board-certified family nurse practitioner, has seen this scenario play out thousands of times in her clinic. “You don’t realize how bad you felt until you start feeling good,” she says. It is a simple observation, but it carries the weight of an entire philosophy — one that challenges the foundational assumptions of modern American healthcare.
Dr. Petersen is the author of The Wellness Glitch and a former Navy nurse who now owns her own clinic and works with patients navigating the gap between what their doctors tell them and what their bodies are telling them. She has spent years advocating for a shift away from what she calls disease management and toward true health optimization — a model that treats the whole person, not just the numbers on a page.
Why “Normal” Is Not the Same as Well
The first problem with the current healthcare model, according to Dr. Petersen, is one of current standards. Lab values are built on averages drawn from a subset of the population, and those averages do not account for the full picture of how any person functions. A result that falls within an established range may still leave a specific person feeling far from their best.
Dr. Petersen sees this most clearly with testosterone. The normal range for men spans a wide window, and a man on the low end can be dismissed as healthy while feeling, in her words, “absolutely terrible.” She reports seeing low-normal testosterone levels across all age groups, which she considers a significant and growing concern worth discussing with a qualified provider.
What frustrates patients is the structure of the average medical appointment. A brief visit focused on whether numbers fall within range leaves little room for the subjective experience of the person in the exam room. Fatigue, mental fog, low libido, and mood changes aren’t meaningless. They are crucially important data points. Dr. Petersen believes a clinician who sets them aside because the labs look acceptable is only seeing part of the picture. She encourages anyone who feels dismissed to seek out a provider who will ask not just what the numbers show, but how they are actually feeling day to day.
Inflammation, Blood Sugar, and the Root Cause Conversation
One of the central ideas in Dr. Petersen’s work is that many chronic conditions share a common underlying driver: inflammation. “When your inflammation is high,” she says, “you are at risk for every chronic disease.” In her view, the healthcare system tends to address the expressions of that inflammation rather than the inflammation itself, managing individual diagnoses rather than looking upstream at what may be fueling them.
Dr. Petersen points to blood sugar regulation as one of the most accessible places to begin. “Being able to control that with blood sugar regulation is really where you need to start,” she says, “when you are looking at ways of improving the status of your health and optimizing your vitality.” She is careful to note that this conversation should happen with a qualified clinician who can assess individual needs, review lab work, and build a plan that fits the specific person rather than a general template.
Her broader point is that asking the question “what is causing this?” is different from asking “how do we manage this?” and that the distinction matters enormously for long-term outcomes. Patients who work with providers oriented toward root cause, she says, often find that addressing foundational imbalances changes far more than the single symptom they originally came in for.
The Hormone Replacement Conversation Worth Having
For women especially, the conversation around hormone replacement has been shaped by fear for more than two decades. Dr. Petersen traces much of that fear to a widely publicized study from the early 2000s that she describes as deeply flawed, noting that it used synthetic hormones and included participants who were already at elevated risk for certain conditions. The findings became near-universal medical consensus, and the effects have lasted a generation.
“There is a generation of women that are really completely sidelined,” Dr. Petersen says, “because they were told that if you do hormone replacement, you are going to get cancer.” She acknowledges that reversing that belief is difficult, particularly for patients who have trusted their providers for decades. But she encourages women who are experiencing changes in energy, mood, sleep, libido, or cognitive clarity to bring those concerns to a provider who specializes in hormonal health and can review current research with them directly.
Dr. Petersen is equally attentive to men. She notes that testosterone levels have been declining across age groups and attributes part of that trend to environmental factors including microplastics. She is careful to note that hormone therapy for men, particularly for those who may want to start a family, requires cautious evaluation and close supervision. The point, she says, is not that everyone should be on hormone therapy. The point is that everyone deserves a provider who will take the conversation seriously and evaluate it individually rather than dismissing it outright.
“You don’t realize how bad you felt until you start feeling good. The hormone regulation has a lot to do with that.”

Understanding GLP-1 Medications Beyond the Headlines
Few topics in health generate more confusion right now than GLP-1 medications, and Dr. Petersen brings a clinical perspective to a conversation often dominated by marketing language on one side and skepticism on the other. She prefers to describe these compounds as peptides rather than medications, noting that at the molecular level they replicate substances the body already produces. For people whose systems do not produce or utilize those substances efficiently, she says, the result often shows up as difficulty regulating appetite and metabolic imbalance that standard dietary approaches rarely resolve on their own.
Dr. Petersen walks through the primary compounds currently available, from semaglutide to tirzepatide, explaining how each works and what the differences are in terms of mechanism and tolerability. She is transparent about the side effects, particularly with semaglutide, and notes that many of them decrease as the body adjusts over time. She recommends these compounds only under medical supervision, with appropriate lab work and follow-up, and frames them not as quick fixes but as tools that can help reduce the inflammatory burden on the body when used responsibly as part of a broader plan.
“They are going to help you get out of an inflammatory state,” she says. “And when you are out of an inflammatory state, your risk for all-cause mortality goes down.” She is clear that these are not her words alone but a growing area of clinical research, and she encourages anyone interested to consult with a qualified provider who can assess whether this approach is appropriate for their individual health picture.
The Foundational Habits That Get Overlooked
Beyond clinical interventions, Dr. Petersen returns consistently to a set of simple practices that she believes have been undervalued because they are not commercially driven. Sunlight is one of them. “I cannot stress enough how much just getting some sunlight during the day can be so beneficial just for your mental health,” she says. In a culture that has heavily promoted sun avoidance, she argues that thoughtful, regular exposure to natural light is something worth discussing with a provider as part of a broader wellness approach.
Mineral balance is another area she raises. Dr. Petersen points out that many people are operating in a low-sodium state without realizing it, not from lack of table salt but from insufficient intake of real mineral salt. “That powers cellular activity,” she explains. “When you can get that going in a much better homeostasis, you feel so much better.” It is the kind of foundational detail that rarely surfaces in brief clinical appointments but can make a meaningful difference in energy and overall function.
Her broader message is that optimization does not always require an elaborate protocol. Sometimes it begins with a single honest conversation with a provider who is willing to ask not just what the labs show, but how the person sitting across from them actually feels.
What You Deserve Is More Than Fine
The distance between not sick and truly well is larger than most people realize, and Dr. Petersen has built her career on helping patients understand what lies on the other side of that gap. The stories she hears from patients who have addressed hormonal imbalances, reduced inflammation, or stabilized blood sugar follow a consistent pattern. They feel like different people. They cannot believe how long they went without asking more from their care.
The first step, she says, is simply refusing to accept dismissal as a final answer. “Keep asking the right questions,” she says. “Don’t take no for an answer because you know deep down this isn’t right.” A conversation with a provider who specializes in optimization, a thorough blood panel, and a willingness to look at the full picture rather than just the numbers — these are accessible starting points that can change the trajectory of someone’s health meaningfully.

Dr. Petersen’s work is a reminder that the healthcare system’s definition of normal was never designed around your optimal function. It was built around averages. And as she makes clear, averages tell only part of the story.
