What is the difference between symptoms and effects of a disease?

Symptoms are the subjective experiences and manifestations of a disease that patients report, such as pain, fatigue, or nausea. Effects, on the other hand, refer to the broader consequences of a disease on the body or overall health, including physiological changes, disability, or complications that may arise. While symptoms are often individual and can vary from person to person, effects are generally more objective and can be observed or measured in a clinical setting.
