Chronic diseases impact quality of life by restricting physical capabilities, creating ongoing healthcare challenges, and escalating financial burdens. Conditions such as diabetes, heart disease, and arthritis may lead to chronic pain, fatigue, and emotional distress, detracting from individuals’ daily activities. Limitations imposed by chronic illnesses can reduce independence and affect mental well-being. Effective disease management through lifestyle interventions and proper medical care is crucial in mitigating these impacts, allowing individuals to achieve a better quality of life despite their health challenges.
