What type of diseases can affect the entire body?

Systemic diseases are those that can affect the entire body, as they typically involve multiple systems or organs rather than being confined to a specific area. These types of diseases can lead to widespread symptoms and can impact various functions throughout the body's biological systems. Examples of systemic diseases include diabetes, lupus, and certain types of cancer, among others.

In contrast, localized diseases occur in a specific area and do not have an extensive impact on other parts of the body, which distinguishes them from systemic diseases. Chronic diseases are long-lasting and typically progress over time, while acute diseases flare up suddenly but tend to resolve either fully or lead to significant acute consequences. Understanding these distinctions helps in recognizing how widespread the effects of systemic diseases can be compared to the more limited impact of localized or acute conditions.
