Causes of chronic illness

 Chronic diseases often do not have a specific cause, but only a group of risk factors contribute to the development of the disease, including Factors of lifestyle behavior such as smoking; abuse of alcohol, beer; poor nutrition, and little physical activity. Behavioral risk factors that will lead to physiological/metabolic changes include hypertension, overweight and obesity, hyperglycemia and dyslipidemia, and consequent coronary heart disease and stroke. , diabetes, cancer...

Here are some risk factors for chronic disease.

1. Smoke:

Smoking is estimated to be the cause of  71% of lung cancer cases; 42% of cases of chronic lung disease; and 10% of cardiovascular diseases. Smoking is also a risk factor for certain infections such as tuberculosis and lower respiratory tract infections.

Around the world, about 6 million people die each year from tobacco use, including secondhand smoke. By 2020, this number will increase to 7.5 million people, accounting for about 10% of all global deaths.

2. Harmful use of alcohol and beer:

Wine, beer, and other alcoholic beverages are addictive substances, so the World Health Organization has recommended ensuring the best health is not to drink alcohol and beer.
In 2012, 5.9%  of global deaths, equivalent to  3.3 million people, were caused by alcohol use, of which most were the consequences of non-communicable diseases including cardiovascular disease, diabetes (33.4%), 9 types of cancer (12.5%), digestive diseases (16.2%), trauma (25.8%) and fetal development disorders and complications alcoholic prematurity (0.1%).

3. Improper nutrition:

Eating fewer vegetables and fruits is believed to be the cause of 1.7 million deaths, accounting for 2.8% of all deaths worldwide. Eating fewer vegetables and fruits is estimated to be responsible for 19% of gastrointestinal cancers, 31% of ischemic heart diseases, and 11% of strokes.
Eating at least 400g of vegetables and fruits a day helps prevent nutrition-related chronic diseases such as cardiovascular diseases, stomach cancer, and colorectal cancer.

4. Less physical activity: 

Physical inactivity is the fourth leading risk factor for death. Some sedentary people have a 20 to 30 percent increased risk of death from all causes compared with someone who is moderately active for at least 30 minutes a day most days of the week.

150 minutes/week of moderate physical activity is estimated to reduce the risk of ischemic heart disease by 30%, the risk of diabetes by 27%, and the risk of breast and breast cancer by 21-25%. Colorectal. Physical activity also reduces the risk of stroke, hypertension, and depression, and helps with weight control.
