Overmedicalization describes a modern trend where natural human conditions are increasingly interpreted through a biomedical lens, transforming them into treatable medical problems. This process extends the boundaries of what is considered normal, suggesting that a growing number of human experiences require medical diagnosis and intervention. This phenomenon affects healthcare systems globally, shifting focus and resources away from non-medical solutions. Understanding this expansion requires examining how it is defined, the forces that drive it, and the negative impacts it has on individual health and collective finances.
Defining the Scope of Overmedicalization
Overmedicalization is defined as the application of medical interventions, diagnoses, or treatments when the potential for harm outweighs the potential benefit for the patient. It differs from necessary medical care by targeting conditions that are mild, self-limiting, or variations of the normal human experience. This expansion often involves lowering diagnostic thresholds, reclassifying healthy populations as being “at risk” or having a “pre-disease.” For instance, new guidelines for mild hypertension or prediabetes dramatically increase the number of people needing ongoing monitoring and treatment. This expansion is accelerated by “disease mongering,” a strategy that widens the boundaries of an illness to enlarge the market for treatments by framing common symptoms as serious medical pathologies.
Systemic Drivers and Incentives
The primary drivers of overmedicalization are embedded within healthcare delivery structures and commercial interests. Pharmaceutical and device industries actively engage in disease mongering, funding research and awareness campaigns that exaggerate the prevalence or severity of conditions to create new markets. For example, conditions like “Female Sexual Dysfunction” were heavily marketed before treatments were approved, establishing a market need by medicalizing normal human variations. This commercial influence works in tandem with the prevailing fee-for-service (FFS) payment model in many healthcare systems.
The FFS model directly incentivizes providers to deliver a higher volume of services—tests, procedures, and office visits—rather than rewarding quality outcomes or efficiency. Because payment is tied to the quantity of care provided, the system structurally encourages overutilization, leading to unnecessary and costly interventions. Physician behavior is also shaped by the fear of litigation, a practice known as defensive medicine. Over 90% of doctors report ordering more tests and procedures than medically necessary primarily to create a liability shield against potential malpractice lawsuits. This defensive practice includes excessive imaging and referrals, contributing hundreds of billions of dollars annually to healthcare costs without corresponding patient benefit.
Common Manifestations in Clinical Practice
The effects of overmedicalization are visible across many areas of clinical care, often appearing as aggressive intervention in low-risk or natural life contexts. The overuse of screening tests for low-risk conditions frequently leads to the detection of abnormalities that would never have caused harm, known as overdiagnosis. Overdiagnosis triggers a cascade effect of unnecessary follow-up tests, biopsies, and treatments, introducing harm where none existed. The medicalization of normal life processes is also widespread, notably framing natural transitions like menopause as a “deficiency condition” requiring long-term hormone replacement therapy.
Life events such as childbirth and aging have also been increasingly brought under medical control, often leading to interventions like elective C-sections or anti-aging procedures. Overmedicalization profoundly impacts the end-of-life experience. Despite patient preferences for comfort and dignity, a significant percentage of people receive non-beneficial, invasive treatments in their final weeks. Studies indicate that up to 38% of elderly patients with advanced, irreversible conditions are subjected to aggressive interventions like chemotherapy, intensive care unit admissions, or cardiopulmonary resuscitation (CPR), which only prolongs suffering.
The Human and Economic Consequences
The consequence of unnecessary medical expansion is a substantial toll on both individual well-being and national economies. Physically, overmedicalization leads directly to iatrogenesis—harm caused by medical activity itself—including adverse drug reactions, complications from unnecessary surgeries, and hospital-acquired infections. Estimates suggest that iatrogenic disorders may cause as many as 250,000 deaths annually in the United States, positioning it as a major cause of mortality. Psychologically, labeling healthy individuals with a “pre-disease” or mild risk factor can induce anxiety, stigma, and a loss of autonomy.
Economically, the sheer volume of unnecessary services generates significant waste within the healthcare system. Annual wasteful spending in the U.S. is estimated to range between $760 billion and $935 billion, representing nearly one-quarter of total healthcare expenditures. The overtreatment of low-value care alone contributes an estimated $75 billion to $101 billion to this waste. This financial drain diverts resources from essential public health services and necessary care, straining public budgets and increasing costs for patients through high premiums and out-of-pocket expenses.
