When most people think of the top 5 dangerous diseases in the world, they think of the fast-acting, incurable ones that make headlines from time to time. However, several of these diseases do not rank among the top ten causes of death worldwide.
In 2019, an estimated 55.4 million people died worldwide, with noncommunicable diseases, or chronic ailments that advance slowly, accounting for 74% of these fatalities.
Even more shocking, several of the deadliest diseases are at least partially avoidable. Non-preventable risk factors include where a person lives, access to preventative treatment, and the quality of healthcare.
These top 5 dangerous diseases of the world are:
- 1. Ischemic heart disease, or coronary artery disease.
- 2. Stroke
- 3. Lower respiratory infections
- 4. Chronic obstructive pulmonary disease.
- 5. Trachea, bronchus, and lung cancers.
Ischemic heart disease, or coronary artery disease.
The deadliest disease in the world is coronary artery disease (CAD).
Also called ischemic heart disease, CAD occurs when the blood vessels that supply blood to the heart become narrowed. Untreated CAD can lead to chest pain, heart failure, and arrhythmias.
The Worldwide Effect of CAD:
Although it is still the main cause of death in several European countries and the United States, fatality rates have decreased.
This could be attributed to improved public health education, healthcare access, and other kinds of prevention. However, CAD mortality rates are rising in many emerging countries and as the top 5 dangerous diseases in the world.
This rise is influenced by a growing life expectancy, socioeconomic changes, and lifestyle risk factors.
Risks and prevention of the top 5 dangerous diseases in the world:
Risks:
- Risk factors for CAD include:
- high blood pressure.
- high cholesterol
- smoking
- family history of CAD
- diabetes
Prevention:
If you have one or more of these risk factors, consult a doctor or a healthcare professional.
You can avoid CAD with drugs and by improving your heart health. You can reduce your risk by doing the following:
exercising on a regular basis
achieving or maintaining a healthy weight
eating a well-balanced diet high in fruits and vegetables and low in salt
if applicable, refraining from smoking
Only drink in moderation.
Stroke.
When a brain artery is stopped or leaky, a stroke happens. The brain cells become oxygen-deprived as a result, and within minutes, they start to die.
You may experience abrupt numbness, confusion, or difficulty walking and seeing during a stroke. A stroke can result in long-term disability if it is not addressed.
In actuality, strokes are the main factor in long-term impairments. the top 5 dangerous diseases in the world Following a stroke, people who receive treatment within three hours are less likely to develop problems.
Risks and prevention of the top 5 dangerous diseases in the world:
- Risk factors for stroke include:
- high blood pressure
- family history of stroke
- smoking, especially when combined with oral contraceptives
- being African American
- being female
With preventative care, drugs, and lifestyle modifications, several risk factors for strokes can be reduced. Generally speaking, maintaining good health can reduce your risk.
Taking medication to lower high blood pressure is one way to prevent strokes. Maintaining a healthy lifestyle includes getting regular exercise and eating a balanced, low-sodium diet.
Consider stopping smoking and limit your alcohol consumption if you do, as both behaviors raise your risk of stroke.
Lower respiratory infections.
- A lower respiratory infection is an infection in your airways and lungs. It can be due to:
- influenza, or the flu
- pneumonia
- bronchitis
- tuberculosis (TB)
Although bacteria can also cause lower respiratory infections, viruses are typically the culprits.
The primary sign of a lower respiratory infection is coughing. It could result in blood sputum. You might also feel short of breath, wheeze, or have a tightness in your chest, in addition to having a temperature, sweating, or chills.
Risks and prevention:
- Risk factors for lower respiratory infection include:
- the flu
- poor air quality or frequent exposure to lung irritants
- smoking
- a weak immune system
- crowded child care settings, which mainly affect infants
- asthma
- HIV
Getting the flu vaccination each year is one of the strongest preventative measures you can take against lower respiratory illnesses. Pneumonia vaccines are also available for those who are most at risk.
To prevent the spread of bacteria, wash your hands frequently with soap and water, especially before touching your face or handling food.
Chronic obstructive pulmonary disease .
Breathing becomes difficult as a result of the long-term, progressive lung condition known as chronic obstructive pulmonary disease (COPD). Emphysema and chronic bronchitis are examples of COPD.
Approximately 16.4 million Americans reported receiving a diagnosis of COPD in 2018.
Risks and prevention of the top 5 dangerous diseases in the world:
- Risk factors for COPD include:
- smoking or secondhand smoke.
- lung irritants such as chemical fumes.
- family history, with the alpha-1 antitrypsin deficiency gene being linked to COPD
- history of respiratory infections as a child
The course of COPD can be slowed down with treatment, but there is no known cure.
Stopping smoking, if applicable, and avoiding secondhand smoke and other lung irritants are the best ways to prevent COPD. Getting treatment as soon as possible if you have any COPD symptoms will help your perspective.
Trachea, bronchus, and lung cancers.
Respiratory cancers include cancers of the trachea, larynx, bronchus, and lungs.
The main causes are smoking, secondhand smoke, and environmental toxins. However, household pollutions, such as fuels and mold, also contribute.
Effects of respiratory tumors worldwide:
According to a 2015 study, there are over 18 million new instances of lung cancer each year. Researchers predict an 81% to 100% increase in respiratory malignancies in developing nations due to smoking and air pollution.
India is just one of many Asian nations that continue to cook using coal. For males, solid fuel emissions cause 17% of lung cancer deaths, and for females, 22%.
Risks and prevention:
Anyone can get trachea, bronchus, or lung cancer, although individuals with a history of smoking or tobacco use are more likely to be affected.
Family history and exposure to environmental variables like diesel fumes are additional risk factors for these tumors.
It is unknown if there is anything else that can be done to prevent lung cancers outside avoiding fumes and tobacco products. However, regular lung exams and early identification can lead to more successful therapy and a better prognosis.
