It’s important to understand these problems in order to better cope with them and to prevent these issues from impacting you or someone you care about. Listed below are the eight most major health problems in the world today.

1) Heart Disease
Heart disease is a risk for those who smoke, eat a poor diet, don’t exercise, or have high blood pressure. Heart disease often kills people prematurely, and treatment for heart disease can be costly and painful.

3) Respiratory diseases
What’s more, respiratory diseases, such as asthma and chronic obstructive pulmonary disease (COPD), are also on the rise. In 2015, almost 36 million people worldwide suffered from COPD.
4) Chronic obstructive pulmonary disease (COPD)
COPD is a long-term disease that makes it hard to breathe and causes many people to struggle. Over 17 million people are living with COPD today, and it’s expected to be one of the most dangerous diseases by 2020.
5) Diabetes
Diabetes can be hard to diagnose, but early intervention could save your life. If you have been feeling uneasy for a few days, call your doctor right away. Early diagnosis could help prevent serious health problems like kidney failure and heart disease down the road.
6) Nervous system diseases
Nervous system diseases cause more than 500 million people to be unwell each year. What’s more, half of all premature deaths are caused by nervous system diseases.
7) Infectious diseases
Even though these diseases may be treatable, they can still make their sufferers quite sick for extended periods of time. While modern medicine has come a long way, these conditions are largely still fatal to those who have them.
8) Aids
Over 30 million people live with HIV/AIDS, and over 1.2 million more are infected each year. It’s a disease that affects almost everyone on Earth at some point in their lives and leads to horrible deaths for millions of people every year.
Conclusion
It’s impossible to pinpoint a specific reason for each problem, but it is worth noting that something as seemingly innocent as vanity can actually do some serious damage to your health. In fact, anything that hurts your body can be considered a health problem.
