What are Non-Communicable Diseases and Their Causes?
Key Takeaways Non-communicable diseases (NCDs) don't spread from person to person-touch, air, or water doesn't pass these conditions along. Spot the big risk factors early: smoking, bad eating habits, not moving enough, and drinking too much. Keep tabs on your blood pressure, blood sugar, and cholesterol so you can catch issues before they turn serious. Build habits that protect you-better nutrition, regular exercise, managing stress, sleeping well. If you have ongoing symptoms or a history of chronic disease in your family, don't wait-get medical advice.
