It is an uncomfortable truth, but one that becomes clear with closer examination: where you live can matter as much as, or more than, your diagnosis. Most people are taught to view health primarily through a biological lens, focusing on genes, conditions, symptoms, and treatments. We often assume that two individuals with the same diagnosis and care will have similar outcomes. In reality, this assumption does not hold.

Health does not exist in isolation; it is shaped by the context of people’s lives.

I recognized this when I observed what happened after patients left the clinic. Two individuals could receive identical explanations and care plans, yet their experiences afterward often differed significantly. One patient might have the resources and support to follow through, while another could face barriers that make even basic instructions difficult to implement. Over time, these differences accumulate and lead to divergent outcomes.

The diagnosis remained the same; the environment changed.

A person’s surroundings, such as their neighborhood, access to resources, and daily responsibilities, shape what is possible for them. These factors influence whether they can obtain medication, attend follow-up appointments, or make recommended lifestyle changes. They determine access to fresh food and affect whether individuals feel safe exercising or must prioritize managing stress and instability.

These factors are not secondary to care; in many cases, they determine whether care is effective.

Yet these factors are often overlooked in healthcare design.

Inside clinical settings, the focus is understandably on diagnosis and treatment. There’s limited time, a structured process, and a need to move efficiently. But that structure leaves little room to fully understand the realities patients are returning to. It assumes that once instructions are given, people will be able to act on them. It assumes a level of stability and access that simply doesn’t exist for everyone.

That’s where the disconnect begins.

What happens when someone is told to eat healthier, but lives in an area where fresh food is either too expensive or not available? What happens when they’re asked to come back for follow-up care, but don’t have reliable transportation or can’t afford to take time off work? What happens when the stress of daily life makes it difficult to focus on anything beyond getting through the day?

These aren’t rare situations. They’re everyday realities.

Through experience, I have realized that we often emphasize individual responsibility without fully acknowledging the structural challenges people face. We expect individuals to make the right choices without ensuring they have the means to do so.

As a result, we are often surprised when these plans do not succeed.

Recognizing the impact of a person’s environment does not diminish the importance of clinical care; it enhances it. This understanding reminds us that care does not end with a diagnosis or prescription. It continues in the environments people return to, the systems they navigate, and the support they have or lack.

To achieve better outcomes, we must broaden our perspective. We need to look beyond hospitals and clinics and consider the conditions that shape daily life. Until we do, health will continue to be treated solely as a medical issue.

Health is not only a medical issue.

It reflects everything surrounding a person: their environment, access, support, and daily reality.
