Bioethics stands at the intersection of life sciences, medicine, philosophy, and human values. The field emerged from the recognition that advancing medical technologies and scientific capabilities require careful moral consideration. Four core principles guide bioethical reasoning: autonomy (respect for individual choice), beneficence (promoting good), non-maleficence (avoiding harm), and justice (fair distribution of benefits and risks).
In modern healthcare, informed consent represents a cornerstone of ethical practice.

Healthcare teams must navigate complex situations involving withdrawal of care, palliative options, and advance directives. The concept of medical futility raises questions about resource allocation and the balance between extending life and maintaining its quality.
