Non-Communicable Disease - GCSE Biology Definition

A Non-Communicable Disease (NCD) is a type of disease that cannot be passed from one person to another. Unlike infections or contagious illnesses, NCDs develop due to a combination of genetic, lifestyle, and environmental factors. Common examples include heart disease, diabetes, cancer, and asthma. These diseases often last a long time and may gradually get worse. NCDs are often associated with risk factors such as poor diet, lack of exercise, smoking, and excessive alcohol consumption. Managing these diseases usually requires a long-term approach that can include medication, lifestyle changes, and regular medical check-ups.
