Non Communicable diseases
Non communicable diseases
A non communicable disease cannot be passed from one individual to another
They are caused by a person's lifestyle (environment, substance intake, genetics)
For some non-communicable diseases, a causal mechanism for some risk factors have been proven, but not in others
Benign and malignant tumours result from abnormal, uncontrolled cell division
Benign tumours form in one place and do not spread to other tissues.
Malignant tumour cells are cancers. They invade neighbouring tissues, and spread to different parts of the body in the blood, where they form secondary tumours
Lifestyle risk factors for various types of cancer include: smoking, obesity, common viruses and UV exposure.
Smoking and the risk of diseases
Smoking can cause cardio-vascular diseases including coronary heart disease, lung cancer and lung diseases such as bronchitis and COPD.
A foetus exposed to smoke has restricted oxygen, which can lead to premature birth, low birth weight, and even stillbirth.
Diet, exercise and diseases
Diet can affect your risk of developing cardio-vascular and other diseases directly through cholesterol levels and indirectly through obesity.
Exercise levels affect the likelihood of developing cardiovascular diseases.
Obesity is a strong risk factor for type 2 diabetes
Alcohol and other carcinogens
Alcohol can damage the liver and cause cirrhosis
Alcohol can cause brain damage and death
Alcohol taken by a pregnant woman can affect the development of her unborn baby.
