What is a consequence of disease that affects quality of life?

A consequence of disease that affects quality of life is that individuals may experience a lower quality of life. This can manifest in various ways, such as physical pain, reduced mobility, emotional distress, and the inability to engage in daily activities or enjoy leisure time. These effects can lead to a diminished sense of well-being, impacting both mental and emotional health. In contrast, the other options presented do not directly relate to the impact of disease on an individual's day-to-day experiences. Increased spending on luxury items or the development of new medical technologies often occurs in response to broader economic or societal trends rather than an individual's personal health challenges. Additionally, while family gatherings may increase as a form of support in times of illness, they do not directly address the deterioration in quality of life due to disease. Hence, the specific impact on well-being makes lower quality of life the most appropriate choice.
