Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung condition that causes airflow blockage, leading to over 3.2 million deaths annually worldwide according to the World Health Organization (WHO). It is currently the third leading cause of death globally, characterized by chronic inflammation and lung damage that makes breathing increasingly difficult.
The Crisis of Underdiagnosis in COPD
A significant gap exists between the prevalence of COPD and confirmed medical diagnoses. In Spain, the disease affects more than 10% of the population over age 40—roughly three million people—yet only about one million have been diagnosed. This means approximately three out of four cases remain undetected.

Dr. Salud Santos, head of the Pulmonology Service at Hospital de Bellvitge, attributes this trend to a “failure at different levels.” These include insufficient prevention resources in early stages, patients dismissing symptoms as normal signs of aging or smoking, and the technical difficulty professionals face when interpreting spirometry, the primary diagnostic test for the disease.
Understanding Exacerbations and Lung Decay
COPD progresses slowly, often leading patients to normalize persistent coughs or shortness of breath. However, the most dangerous turning points are “exacerbations”—acute episodes where respiratory symptoms worsen rapidly. These are frequently triggered by viral respiratory infections, causing the lungs and bronchi to inflame disproportionately.

According to Iñaki Morán, president of EPOC España and a patient with the disease, these crises are the primary reason for emergency room visits and the strongest predictor of mortality. The impact is “destructive” because each exacerbation can accelerate lung function loss. Morán notes that one in four patients never recovers their previous lung function after a crisis, leaving the body in a state of “absolute fragility.”
The Impact on Autonomy and Mental Health
As lung capacity drops, patients lose the ability to perform basic daily activities. This decline typically follows a specific pattern of loss:
- Leisure: Walking with friends or playing with grandchildren are often the first activities abandoned.
- Basic Tasks: Shopping and household chores become insurmountable.
- Personal Hygiene: Simple acts, such as drying off with a towel after a shower, can become exhausting.
The psychological toll is equally severe. Research indicates that between 40% and 60% of people with COPD experience symptoms of anxiety or depression. This is driven by the fear of the next crisis, the sensation of suffocation, and the loss of independence.
New Biological Treatments and the Shift in Care
For decades, the standard of care has relied on long-acting bronchodilators and “triple therapy” inhalers. However, a paradigm shift is occurring with the introduction of biological drugs. These treatments target specific inflammatory pathways to better control symptoms and prevent the lung deterioration associated with frequent exacerbations.
While some of these biological options have received approval from European regulatory authorities, they are not yet available in Spain. Dr. Salud Santos explains that while these are not universal treatments, well-selected patients with severe COPD can benefit significantly. Morán describes the lack of access to these innovations in Spain as a state of “absolute inequality” that leaves some patients feeling like “second-class” citizens.
COPD Economic and Healthcare Burden
The systemic cost of COPD is substantial due to its high consumption of healthcare resources. In Spain, the disease results in numerous hospitalizations annually, with direct healthcare costs reaching millions of euros per year.

Improving Patient Outcomes
Medical experts agree that improving the prognosis for COPD patients requires a multi-pronged approach. This includes reinforcing early diagnosis through increased spirometry testing in primary care, promoting smoking cessation, and expanding access to respiratory rehabilitation programs. For those with severe disease, the priority is ensuring access to the most advanced treatments available to stop the cycle of exacerbations.
