The TOP 5 Deadliest Diseases Worldwide

Most of these diseases are partially preventable and the factors that make it non-preventable includes the location where the person lives, access to preventive care, and also the quality of healthcare. Here are the Top 5 diseases that are causing most deaths worldwide:

Ischemic Heart Disease (Coronary Artery Disease).

This is the deadliest disease in the world and it happens when the blood vessels that supply blood to the heart narrows. When this is left untreated it can cause chest pains, heart failure, and arrhythmias. Even though this is still the leading cause of death, the mortality rates in most European countries have declined. The risk factors may include high blood pressure, high cholesterol levels, smoking, history of coronary artery disease, diabetes, and also obesity.

One of the most effective ways to prevent Ischemic Heart Disease is by taking medications that will be prescribed by your doctor, and also by maintaining a good heart health. You can do this by exercising regularly, maintaining your weight, and also by eating foods that are low in sodium and more on fruits and vegetables. It can also help if you stop smoking and drink alcohol in moderation.


A stroke happens when an artery on your brain is locked or it leaks which can cause oxygen-deprivation on the brain cells and it will begin to die in just a matter of minutes. During a stroke, a sudden numbness and confusion will be experienced and you will start to have problems walking and seeing. If you left this untreated, this can cause stroke and a long-term disability. Most people who get treatment within 3 hours are less likely to have disabilities.

The risk factors for stroke will include high blood pressure, a family history of the disease, smoking, and being a female. These risk factors can be reduced with proper preventive care, immediate medications, and lifestyle changes. Meaning, following a good health habit, can lower your risk for stroke. Surgery is one of the least options but this can be avoided as long as you control your blood pressure with a healthy lifestyle that is complete with regular exercise and a healthy low-sodium diet.

Getting the flu shot every year is one of the most effective ways to prevent Lower Respiratory Infections. There are people who have a high risk for pneumonia which they can also get a vaccine for. Always make sure that you wash your hands regularly with antibacterial soap and water because this can prevent the transmission of bacteria when you touch your face or before eating.
