Non-infectious diseases are medical conditions that do not spread from person to person. They are often long-term or chronic in nature and usually develop due to genetics, poor lifestyle habits, aging, or environmental factors. These diseases affect millions of people around the world and can impact daily life if not properly managed.
This complete overview will help you understand what non-infectious diseases are, the most common types, their causes, symptoms, treatments, and how to prevent them.
What Are Non-Infectious Diseases?
Non-infectious diseases are not caused by bacteria, viruses, or other pathogens. Instead, they are often related to internal changes in the body, such as hormone imbalance, cell damage, or immune system issues.
Some may be inherited, while others develop over time due to unhealthy habits or environmental exposure. Unlike infectious diseases, you cannot catch these conditions from someone else.
