Death is a very natural phenomenon. If you are born, you have to die: There is no way to escape it. Countless people die every day around the world, for a wide variety of reasons. The World Health Organization has identified the top 10 causes of death in the world.

10. Tuberculosis

Tuberculosis (or TB) is an infectious disease. A bacterium called Mycobacterium tuberculosis is responsible for it. Being infected with tuberculosis meant certain deaths at one time. It was said that there was no cure. But now, with the discovery of effective treatments, it is becoming possible to cure it. As a result, the number of deaths due to tuberculosis has reduced significantly, yet it still ranks tenth among the top 10 causes of death globally.

9. Diarrhea

About 1.5 million people worldwide die each year from diarrhea. Repeated thin bowel movements cause the body to lose water and salts. If the patient's dehydration and salt deficiency are not helped in time, there is a risk of death. Diarrhea is usually contracted by consuming contaminated food and water. The discovery of dietary saline has greatly reduced the death rate from diarrhea.

8. Road Accidents

Road accidents are one of the leading causes of death in the world. The death rate due to road accidents increases every year. The number of deaths in road accidents is relatively higher in the underdeveloped and developing world than in the developing world. Experts believe that with the proper use of technology and observance of traffic rules, it is possible to reduce the rate of road accidents to a great extent.

7. Diabetes

According to the World Health Organization, diabetes is the seventh leading cause of death in the world today. Diabetes is a condition in which the production of the hormone insulin in the body decreases or the amount of glucose increases abnormally for any reason. Studies have shown that two diabetics are diagnosed every 10 seconds in the world and one diabetic dies every 10 seconds. Diabetes cannot be completely cured. However, if some rules are followed, it can be controlled and a healthy life can be lived. At present, more than 400 million people worldwide have diabetes, and about 1.7 million of these victims die each year.

6. Lung Cancer

Lung cancer is one of the leading causes of cancer deaths. Middle-aged and older people are more likely to be affected by this disease. According to statistics, more than 1.7 million people worldwide die of lung cancer every year. About 15% of those affected by the disease are smokers. Physicians are trying to provide the best medical care to lung cancer patients through surgery, radiation, therapy, etc. However, effective treatment methods for curing cancer have not yet been discovered; as a result, most people with lung cancer die.

5. Alzheimer's Disease

Alzheimer's is a type of brain disease in which the patient cannot remember anything. The incidence of this disease is also high as there are no specific symptoms and no effective treatment method has been discovered. The first symptom of this disease is memory loss.

4. Lower Respiratory Tract Infections

Diseases of the respiratory system (bronchitis, pneumonia, laryngitis, influenza, etc.) are called lower respiratory tract infections or LRTI. About 4 million people worldwide die each year from these diseases. Although children are at the top of the list for lower respiratory tract infections, adults are also at risk. These diseases are transmitted by viruses or bacteria and infect the lungs and airways. About 6,000 liters of air enter and exit our lungs through our airways every day, and the causes of these diseases usually enter the body with this air. If a person's respiratory immunity is good, then these diseases don't cause infections—but if the respiratory system is weakened for any reason, it may be infected.

3. Chronic Obstructive Pulmonary Disease

One of the causes of shortness of breath is chronic obstructive pulmonary disease (COPD), a long-term acute inflammatory disease of the lungs. The walls of the airways become thick and air gets trapped in the small air sacs inside the lungs. As a result, air cannot enter the lungs. COPD kills more than 4 million people worldwide every year. The main symptoms are chronic cough, tightness in the chest, fatigue, wheezing, shortness of breath, coughing up mucus, and so on. Usually smokers are more affected, but any person exposed to polluted air can develop chronic obstructive pulmonary disease.

2. Stroke

Stroke usually occurs when the blood flow to the brain is obstructed. The rate of stroke is increasing every year due to uncontrolled high blood pressure, smoking, drug use, excessive consumption of soft drinks, excessive consumption of salt, uncontrolled diabetes, high blood fat, obesity, tension, etc. Stroke kills more than six million people worldwide each year.

1. Ischemic Heart Disease

According to the World Health Organization, ischemic heart disease (aka coronary artery disease) is the leading cause of death worldwide and kills more than 9 million people every year. Diabetes, smoking, high blood cholesterol levels, high fat diets, high blood pressure, etc. cause this complex heart disease. Family history and age are also largely responsible for its development. Chest pain is one of the main symptoms of ischemic heart disease. Studies show that people in Europe are more likely to die of a heart attack than people in South Asia. Their eating habits are largely responsible.
