Causes and Diseases of Death

Every day around 385,000 babies are born and nearly 150,000 people die per day globally. There is one way to take birth but many causes of death. People have been taking birth and dying for millions of years. Your age maybe 60 years, 80 years, or 100 years but some die at a young age due to wrongful death or any physical illness. 

People’s life starts decreasing from the date he/she born. But all of us foolish, enjoy our birthday every year and say ‘age has increased’. Our grandpa live more year than us because they do more physical activities, has better mental health than us, and eat organic foods.

8 Leading Causes of Death Globally According to WHO and CDC

However, still more people are taking birthdays than dying. But still, people are dying due to modern diseases. The following are the leading diseases of death globally according to the World Health Organization and CDC report.

Ischaemic heart disease

Ischaemic heart disease, also known as coronary artery disease, is a leading cause of death due to the obstruction of blood flow to the heart. This leads to heart attacks, arrhythmias, heart failure, and sudden cardiac death. Risk factors include high blood pressure, high cholesterol, smoking, diabetes, obesity, and family history.


Cancer is a leading cause of death due to the uncontrolled growth and spread of abnormal cells in the body. It can occur in any organ or tissue and can lead to organ failure and death. Risk factors include genetic predisposition, exposure to carcinogens, unhealthy lifestyle habits, and certain infections. Advances in treatment and early detection have improved outcomes, but cancer remains a major global health challenge.


COVID-19 is a leading cause of death because it is a highly contagious respiratory illness caused by the SARS-CoV-2 virus, which can cause severe respiratory symptoms, pneumonia, and acute respiratory distress syndrome (ARDS). COVID-19 primarily spreads through respiratory droplets and close contact with infected individuals. Risk factors for severe illness and death include advanced age, underlying medical conditions, and weakened immune systems. As of 2021, COVID-19 has caused millions of deaths globally and continues to be a significant public health threat.

Lower respiratory infections

Lower respiratory infections, such as pneumonia and bronchitis, are leading causes of death due to the inflammation and infection of the lungs, leading to breathing difficulties and respiratory failure. These infections can be caused by a variety of viruses, bacteria, and other pathogens and can be particularly dangerous for young children, the elderly, and individuals with weakened immune systems. Risk factors for lower respiratory infections include exposure to air pollution, smoking, and crowded living conditions. Timely diagnosis and treatment with appropriate antibiotics or antivirals are critical to reducing morbidity and mortality associated with lower respiratory infections.


Accidents are a leading cause of death because they can happen suddenly and unexpectedly, causing severe injury or trauma. Common types of accidents include motor vehicle crashes, falls, drowning, and accidental poisonings. Risk factors include hazardous work environments, unsafe behaviors, lack of safety equipment, and impaired driving or judgment due to alcohol or drug use. Preventative measures such as education, training, and safety regulations can help reduce the incidence of accidents and associated fatalities.

Alzheimer’s disease is a leading cause of death due to the progressive and irreversible loss of brain cells, leading to cognitive decline, memory loss, and ultimately, organ failure. Risk factors include advanced age, genetic predisposition, and lifestyle factors such as high blood pressure, diabetes, and obesity.


Diabetes is a leading cause of death due to chronic high blood sugar levels that damage organs and increase the risk of heart disease, stroke, kidney failure, blindness, and lower limb amputations. Risk factors include obesity, physical inactivity, unhealthy diet, genetics, and certain medical conditions.

Kidney and Liver Disease

Kidney and liver disease are leading causes of death due to the progressive damage and dysfunction of these vital organs. Chronic kidney disease and liver disease can be caused by factors such as diabetes, high blood pressure, alcohol abuse, viral hepatitis, and certain medications. Without proper treatment, kidney and liver disease can lead to organ failure, which can be fatal. Early detection and management are critical to prevent complications and improve outcomes.

There are also many people who got died but we couldn’t find the reason. It may be due to a small illness, doctor negligence, or other reason that cannot be explained.
