Top 10 Deadliest Diseases

 

Overview

When people think of the deadliest diseases in the world, their minds may jump into those fast, incurable diseases that make headlines from time to time. But in fact, many of these types of diseases are not the top ten causes of death worldwide. In 2015, an estimated 56.4 million people died from trusted sources worldwide, 68% of which were due to slow disease progression.

Perhaps even more surprising is that some of the most deadly diseases can be partially prevented. Unpreventable factors include a person’s residence, access to preventive care, and the quality of medical care. These factors all lead to risks. However, everyone can still take some measures to reduce risk.

According to reliable sources from the World Health Organization (WHO), read on to learn about the top ten diseases that cause the most deaths in the world.

1. Ischemic heart disease or coronary artery deadliest disease

 

The deadliest disease in the world is coronary artery disease (CAD). Also known as ischemic heart disease, CAD occurs when the blood vessels supplying the heart narrow. Untreated CAD can cause chest pain, heart failure, and arrhythmia.

The impact of CAD on a global scale

Although it is still the main cause of death, death rates have fallen in many European countries and the United States. This may be due to better public health education, access to medical care, and forms of prevention. However, in many developing countries, the death rate of CAD is rising. The increase in life expectancy, socioeconomic changes, and lifestyle risk factors have played a role in this rise.

Risk factors and prevention
Risk factors for CAD include:

  • hypertension
  • High cholesterol
  • smokes
  • CAD family history
  • diabetes
  • overweight

If you have one or more of these risk factors, please consult your doctor.

You can prevent CAD through medication and maintaining good heart health. Some steps you can take to reduce risk include:

  • Exercise regularly
  • Maintain a healthy weight
  • Eat a balanced diet, low sodium, high in fruits and vegetables
  • Avoid smoking
  • Drink only moderately

2. Stroke

 

A stroke occurs when the arteries in the brain are blocked or leaked. This causes hypoxic brain cells to begin to die within a few minutes. When you have a stroke, you may feel sudden numbness and confusion, or difficulty walking and seeing. If left untreated, a stroke can cause long-term disability.

In fact, stroke is the main cause of long-term disability. People who receive treatment within 3 hours of a stroke are less likely to be disabled. A trusted source from the Centers for Disease Control and Prevention (CDC) reports that 93% of people know that sudden numbness on one side is a stroke symptom. But only 38% knew all the symptoms that would prompt them to seek urgent care.

Risk factors and prevention
Risk factors for stroke include:

  • hypertension
  • Family history of stroke
  • Smoking, especially when combined with oral contraceptives
  • Are African American
  • being female

Preventive care, medications, and lifestyle changes can reduce certain risk factors for stroke. Generally, good health habits can reduce risks.

Ways to prevent a stroke may include medication or surgery to control high blood pressure. You should also maintain a healthy lifestyle and engage in regular exercise and a healthy diet with low sodium. Avoid smoking and only drink alcohol in moderation, as these activities increase the risk of stroke.

 

3. Lower respiratory tract infection

 

Lower respiratory tract infections are infections of your respiratory tract and lungs. This may be due to:

  • Flu or flu
  • pneumonia
  • bronchitis
  • tuberculosis

Viruses usually cause lower respiratory tract infections. They may also be caused by bacteria. Cough is the main symptom of lower respiratory tract infection. You may also experience difficulty breathing, wheezing, and tightness in your chest. Untreated lower respiratory infections can cause respiratory failure and even death.

The impact of lower respiratory tract infections worldwide
Risk factors and prevention
Risk factors for lower respiratory tract infections include:

  • influenza
  • Poor air quality or frequent exposure to lung irritation
  • smokes
  • Weak immunity
  • Crowded childcare facilities, mainly affecting babies
  • asthma
  • AIDS virus

One of the best preventive measures to prevent lower respiratory tract infections is to inject the flu once a year. People at high risk of pneumonia can also be vaccinated. Wash your hands regularly with soap and water to avoid spreading germs, especially before touching your face and eating. Stay at home and rest until your respiratory infection makes you feel better because rest will improve healing.

4. Chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is a long-term progressive lung disease that makes breathing difficult. Chronic bronchitis and emphysema are types of COPD. In 2004, there were approximately 64 million trusted people living with COPD in the world.

The impact of chronic obstructive pulmonary disease worldwide
Risk factors and prevention
Risk factors for COPD include:

  • Smoking or secondhand smoke
  • Lung irritants such as chemical fumes
  • Family history, in which the AATD gene is associated with COPD
  • History of respiratory infections as a child

There is currently no cure for COPD, but drug treatment can slow its development. The best way to prevent COPD is to stop smoking and avoid secondhand smoke and other lung irritants. If you experience any symptoms of COPD, getting treatment as soon as possible will increase your sight.

5. Trachea, bronchus, and lung cancer

 

Respiratory cancers include the trachea, larynx, bronchus, and lung cancer. The main reasons are smoking, second-hand smoke, and environmental toxins. However, household pollution such as fuel and mold can also cause pollution.

The impact of respiratory cancer worldwide
A 2015 study reported that respiratory cancer causes about 4 million deaths each year. In developing countries, researchers predict that the incidence of respiratory cancer will increase by 81% to 100% due to pollution and smoking. Many Asian countries, especially India, still use coal for cooking. Solid fuel emissions account for 17% of lung cancer deaths in men and 22% in women.

Risk factors and prevention
The trachea, bronchus, and lung cancer can affect anyone, but it is most likely to affect people who have smoked or a history of smoking. Other risk factors for these cancers include family history and exposure to environmental factors such as diesel fumes.

Apart from avoiding smoke and tobacco products, there is no other way to prevent lung cancer. However, early detection can improve your vision and reduce the symptoms of respiratory cancer.

6. Diabetes

 

Diabetes is a group of diseases that affect the production and use of insulin. In type 1 diabetes, the pancreas cannot produce insulin. The reason is not clear. In type 2 diabetes, the pancreas cannot produce enough insulin or cannot use insulin effectively. Type 2 diabetes can be caused by a variety of factors, including poor diet, lack of exercise, and overweight.

The impact of diabetes on the world
People in low- and middle-income countries are more likely to die from complications of diabetes.

Risk factors and prevention
Risk factors for diabetes include:

  • overweight
  • hypertension
  • Older
  • Irregular exercise
  • Unhealthy diet

Although it is not always possible to prevent diabetes, you can control the severity of symptoms by exercising regularly and maintaining good nutrition. Adding more fiber to the diet can help control blood sugar.

7. Alzheimer’s and other dementias

 

When you think of Alzheimer’s disease or dementia, you may think of memory loss, but you may not think of losing your life. Alzheimer’s disease is a progressive disease that destroys memory and interrupts normal mental functions. These include thinking, reasoning, and typical behavior.

Alzheimer’s disease is the most common type of dementia-60% to 80% of dementia cases are actually Alzheimer’s disease. The disease first causes mild memory problems, difficulty in recalling information, and decreased memory. However, as time passes, the disease will develop and you may not be able to remember for a long time. A 2014 study found that the number of deaths from Alzheimer’s disease in the United States may be higher than reported.

Risk factors and prevention
Risk factors for Alzheimer’s disease include:

  • Over 65
  • Family history of the disease
  • Genes for inheriting diseases from parents
  • Existing mild cognitive impairment
  • Down syndrome
  • Unhealthy lifestyle
  • Is female
  • Previous head trauma
  • Being rejected by the community or interacting with others for a long time

There is currently no way to prevent Alzheimer’s disease. Research is not clear why some people develop it while others do not. While they are trying to understand this, they are also trying to find prevention techniques.

A diet that is good for heart disease may be one thing that helps reduce the risk of disease. A diet rich in fruits and vegetables, low in saturated fat from meat and dairy products, and a diet rich in high-quality fats such as nuts, olive oil, and lean fish may not only help you reduce your risk of heart disease, but also protect Your health, your brain is also suffering from Alzheimer’s disease.

 

8. Dehydration caused by diarrhea

 

Diarrhea refers to the passage of three or more sparse stools in a day. If diarrhea persists for more than a few days, your body will lose too much water and salt. This can lead to dehydration, which can lead to death. Diarrhea is usually caused by enteric viruses or bacteria that are spread through contaminated water or food. It is especially common in developing countries with poor sanitation.

The impact of diarrhoeal disease worldwide
Diarrheal disease is the second leading cause and a convincing source of death for children under 5 years of age. Approximately 760,000 children die from diarrhoeal diseases every year.

Risk factors and prevention
Risk factors for diarrheal diseases include:

  • Living in an area with poor sanitation
  • No access to clean water
  • Age, children are most likely to have severe symptoms of diarrhea
  • Malnutrition
  • Weakened immune system

According to UNICEF, the best prevention method is to maintain good hygiene. Good handwashing techniques can reduce the incidence of diarrhea by 40%. Improving sanitation and water quality and receiving early medical intervention can also help prevent diarrhoeal diseases.

 

9. Tuberculosis

 

Tuberculosis (TB) is a lung disease caused by a bacterium called Mycobacterium tuberculosis. It is a treatable airborne bacteria, although some strains are resistant to conventional treatments. Tuberculosis is one of the main causes of death among people living with HIV. Approximately 35% of AIDS-related deaths are caused by tuberculosis.

The impact of tuberculosis on the world
Since 2000, annual tuberculosis cases have fallen by 1.5%. The goal is to end tuberculosis by 2030.

Risk factors and prevention
Risk factors for tuberculosis include:

  • diabetes
  • HIV infection
  • Lower weight
  • Distance to TB patients
  • Regular use of certain drugs, such as corticosteroids or drugs that suppress the immune system

The best way to prevent tuberculosis is to get the Bacille Calmette-Guerin (BCG) vaccine. This is usually given to children. If you think you have been exposed to tuberculosis bacteria, you can start taking a treatment called chemoprevention to reduce the possibility of illness.

 

10. Cirrhosis of the liver

 

Cirrhosis is the result of long-term or long-term scar formation and damage to the liver. This damage may be the result of kidney disease, or it may be caused by diseases such as hepatitis and chronic alcoholism. A healthy liver filters out harmful substances in the blood and sends healthy blood into the body. When substances damage the liver, scar tissue is formed. As more and more scar tissue forms, the liver must work harder to function properly. Eventually, the liver may stop working.

Risk factors and prevention
Risk factors for cirrhosis include:

  • Long-term drinking
  • Fat accumulation around the liver (non-alcoholic fatty liver disease)
  • Chronic viral hepatitis

Stay away from behaviors that may cause liver damage to help prevent liver cirrhosis. Long-term alcohol consumption and abuse are one of the main causes of liver cirrhosis, so avoiding alcohol can help you prevent damage. Similarly, you can avoid non-alcoholic fatty liver by eating a healthy diet rich in fruits and vegetables and low in sugar And fat. Finally, you can reduce the possibility of contracting viral hepatitis by using protective measures during sex and avoid sharing anything that may have traces of blood. This includes needles, razors, toothbrushes, etc.

Takeaway

Although the number of deaths caused by certain diseases has increased, the number of deaths caused by more serious conditions has also decreased. Certain factors, such as extended lifespan, will naturally increase the incidence of diseases such as CAD, stroke, and heart disease. However, many diseases on this list are preventable and treatable. With the continuous development of medicine and the development of preventive education, we may see a decline in the mortality rate of these diseases.

A good way to reduce the risk of any of these diseases is to maintain a healthy lifestyle through good nutrition and exercise. Avoiding moderate smoking and drinking alcohol can also help. For bacterial or viral infections, proper handwashing can help prevent or reduce the risk.
