Objective: To discuss the right to health protection in Spain and its non-inclusion in the category of fundamental rights. Methodology: Critical review of Spanish and international normative documents - Constitution, laws, and international treaties - from the perspective of analyzing health as a fundamental right. Results: The guarantee and effectiveness of the right to health in Spain are not satisfactory, as from the legislative and often administrative regulation of the topic, well-defined and enforceable legal claims arise before judicial bodies, as individual subjective rights. This allows the legislator to introduce significant setbacks in determining the scope of the right to health. Conclusion: A constitutional reform is necessary to reconfigure a right and include it in the list of those considered fundamental in Section 1 of Chapter II of Title I of the Constitution, in order to endow it with an essential content, binding for the legislator, and so that it itself benefits from direct and maximum jurisdictional guarantee, both ordinary and extraordinary, before the Constitutional Court.
