Causes of death worldwide
The top 10 causes of death account for 55% of deaths worldwide. The leading global causes of death are related to cardiovascular (ischemic heart disease, stroke), respiratory (chronic obstructive pulmonary disease, lower respiratory tract infections) and neonatal conditions, including birth asphyxia and trauma, neonatal infections and sepsis, and complications derived from premature birth. The causes of death can be classified into three groups: communicable (maternal, perinatal and nutritional conditions, infectious and parasitic diseases), non-communicable (chronic) and injuries.
The 10 most common causes of death in the world
Rank 1: Heart disease
Heart disease was the leading cause of death, accounting for 20.6% of all deaths, with a total of 696,962 deaths. Heart disease encompasses several conditions that affect the heart and blood vessels, many of which are related to atherosclerosis, a condition in which plaque builds up on the walls of arteries, narrowing and hardening them, and potentially causing blood clots. , strokes or heart attacks. Other possible complications include angina, cardiac arrhythmias, and heart failure. Preventing heart disease includes maintaining a healthy weight, exercising regularly, and eating a nutritious diet.
Rank 2 – Cancer
Cancer accounted for 17.8% of all deaths, with a total of 602,350 deaths. Cancer is a condition that occurs when old or abnormal cells in the body do not die and continue to produce new cells, causing excessive cell growth that can interfere with normal body functions. Cancer can develop anywhere in the body and spread to other areas, including organs and lymph nodes.
The two main types of cancer are
Cancers can be classified into two main types: hematological (blood) cancers and solid tumor cancers. Hematological cancers affect blood cells and examples include leukemia, lymphoma and multiple myeloma. Solid tumor cancers, on the other hand, involve malignant growths or lumps that affect various organs or tissues in the body. Common types of solid tumor cancers include breast, prostate, lung, and colorectal cancers.
The causes of cancer can be attributed to a variety of factors such as genetic predisposition, lifestyle habits, and exposure to environmental toxins. However, in many cases, the exact cause of cancer is unknown.
Taking steps to prevent cancer includes exercising regularly, maintaining a healthy diet, and avoiding prolonged sun exposure. Additionally, limiting alcohol consumption and quitting smoking are also important preventive measures.
Rank 3 – COVID-19
COVID-19 was one of the leading causes of death, the first time a virus caused so many deaths. The disease is caused by a virus called SARS-CoV-2, which is highly contagious and affects various parts of the body, including the respiratory system and lungs.
SARS-CoV-2 can spread in three main ways: by inhaling air contaminated with small droplets and particles containing the virus when close to an infected person; contact with small droplets and particles containing the virus that land in the eyes, nose or mouth, particularly when coughing and sneezing; and touching your eyes, nose, or mouth with hands that have the virus.
COVID-19 symptoms can range from mild to severe or none at all. Older adults and people with pre-existing medical conditions are more susceptible to becoming seriously ill from the virus. Post-COVID conditions are also a possible concern.
Preventing COVID-19 means getting vaccinated, wearing masks, and washing your hands frequently. People can also minimize their risk by avoiding crowded areas, indoor spaces, and close contact with other people.
Rank 4: Unintentional accidents or injuries
Accidents or unintentional injuries were the fourth leading cause of death, accounting for 5.9% of all deaths. Unintentional falls, car accidents, and unintentional poisoning were the most common types of accidents resulting in death.
To prevent accidental deaths, communities can adopt strategies and projects that focus on creating walkable communities, providing safe routes to school, and improving transportation safety. For older adults, certain programs can help prevent falls by promoting education, home safety, physical activity, and medication management.
Rank 5 – Stroke – Cerebrovascular diseases
Stroke accounted for 4.7% of all deaths. Stroke is a type of cerebrovascular disease that occurs when the arteries supplying blood to the brain burst, rupture, or become blocked by a clot, depriving the brain of needed oxygen and causing brain cells to die.
A healthy lifestyle, including a nutritious diet, regular exercise, and maintaining a moderate weight, can help prevent strokes. Additionally, quitting smoking and reducing alcohol consumption can also reduce the risk of stroke.
Rank 6 – Chronic lower respiratory tract diseases
Chronic diseases of the lower respiratory tract were responsible for 152,657 deaths, which represents 4.5% of total deaths. These diseases can cause breathing difficulties, chronic cough and excessive sputum production by affecting lung function. Chronic obstructive pulmonary disease, bronchitis, emphysema, asthma and pulmonary hypertension are some of the chronic diseases of the lower respiratory tract. To prevent these diseases, people can quit smoking, reduce exposure to allergens and pollutants, and maintain a healthy diet.
Rank 7 – Alzheimer’s Disease
Dementia caused 134,242 deaths, representing 4% of all deaths. Dementia is a broad term used to describe the gradual loss of cognitive abilities such as memory, language and problem solving, which can ultimately affect daily functioning.
Alzheimer’s disease is the most common form of dementia and is characterized by a decline in memory, thinking and behavior that worsens over time. It usually begins with mild memory loss and can eventually lead to an inability to communicate, react to the environment, and move properly.
To help reduce the risk of developing Alzheimer’s disease, people can maintain a healthy lifestyle by exercising regularly, eating a balanced diet, and improving heart health. Additionally, engaging in brain-stimulating activities, cultivating strong social connections, and getting enough sleep can also be beneficial.
Rank 8 – Diabetes
Diabetes was responsible for 102,188 deaths, which represented 3% of total deaths. Diabetes is a chronic disease caused by the body’s inability to produce or use insulin, a hormone that regulates blood sugar levels. Patients with type 1 diabetes need daily insulin injections because they do not produce insulin and there is no known way to prevent it. Patients with type 2 diabetes cannot use insulin effectively and usually require medication to control their blood glucose levels. Eating a balanced diet and exercising regularly are effective measures to prevent and treat type 2 diabetes.
Rank 9: influenza and pneumonia
Influenza caused 53,544 deaths, which represents 1.6% of total deaths. Influenza is a respiratory infection caused by a virus that affects the nose, throat and lungs. This infection is a common cause of viral pneumonia, which can also be caused by bacteria or fungi. Pneumonia causes lung inflammation and causes breathing difficulties. Preventive measures to avoid influenza and pneumonia include quitting smoking, limiting alcohol consumption, and avoiding exposure to toxic chemicals, pollutants, or fumes.
Rank 10: nephritis, nephrotic syndrome and nephrosis: kidney disease
Chronic kidney disease caused 52,547 deaths, which represented 1.6% of total deaths. Chronic kidney disease encompasses conditions that damage the kidneys, causing decreased function and a buildup of waste in the body. This can cause a variety of complications, such as high blood pressure, anemia, and weakened bones, as well as nutrition problems and nerve damage.
Preventing chronic kidney disease involves several measures, such as maintaining a healthy weight and blood pressure, being physically active, and following a low-sodium diet. Additionally, people should avoid smoking and limit alcohol consumption.
What is the main cause of death in the world?
Heart disease, also known as cardiovascular disease, is the leading cause of death worldwide. It is a broad term that covers various conditions that affect the heart and blood vessels, such as coronary artery disease, heart failure, and arrhythmias. Risk factors for heart disease include high blood pressure, high cholesterol levels, smoking, diabetes, obesity and a sedentary lifestyle. While some risk factors can be modified, others cannot. Preventing and treating heart disease involves lifestyle changes, such as eating a healthy diet, exercising regularly, stopping smoking, and managing stress. Early detection and treatment are also crucial to reducing the morbidity and mortality associated with heart disease.
