The deadliest diseases in the world are life-threatening. Some are not curable but can be managed by being on medication. There is also room for prevention.
These diseases develop as a result of lifestyles such as smoking, consuming unhealthy diets, and not exercising. Others are blood pressure, genetics, and so on.
Here are the top deadliest diseases in the world based on the Healthline list.
1. Coronary Artery Disease
The deadliest disease in the world is Coronary Artery Disease (CAD), which is also called “Ischemic Heart Disease.” This disease occurs when the blood vessels that supply blood to your heart reduce. It can result in heart failure, chest pain, and arrhythmias. High blood pressure, smoking, diabetes, family history, and high cholesterol are what causes CAD. You can prevent it by exercising, eating vegetables and fruits, and avoiding smoking.

2. Stroke
A stroke occurs when the artery in your brain is blocked. This leads to your brain cells being deprived of oxygen, and then they begin to die. That’s why those with strokes feel sudden confusion or trouble seeing or walking. If not attended to on time, it can lead to long-term disability.
Stroke is caused by smoking, genetics, high blood pressure, and contraceptives. You can prevent it by controlling your blood pressure, embracing a healthy lifestyle, and exercising regularly.
3. Lower Respiratory Infections
This is an infection that affects your lungs and airways. It can be caused by pneumonia, tuberculosis, bronchitis, flu, and bacteria. Coughing is the major symptom of lower respiratory infections. Other factors are smoking, HIV, a weak immune system, and asthma. You can prevent lower respiratory infections by washing your hands regularly to avoid bacteria and also getting vaccines.
4. Chronic Obstructive Pulmonary Disease
This is another deadly disease that causes long-term lung disease that leads to difficulty in breathing. Smoking, family history, and lung irritants are what cause COPD. There is no cure, but it can be managed with adequate medication. If you don’t want this disease, don’t smoke.
5. Respiratory Cancers
Respiratory cancers consist of the lung, bronchus, and trachea cancers. Environmental toxins, smoking, and pollution cause them. If you love taking tobacco a lot or even smoking, you have a higher chance of getting any of these respiratory cancers. But doing otherwise would help you.
6. Diabetes
Diabetes is also a disease that kills faster than you think. It occurs when the pancreas cannot produce insulin, or insulin becomes unuseful. This disease can damage your nerves and blood vessels. Diabetes is a result of high blood pressure, unhealthy diet, and obesity. This disease is not always preventable, but eating healthy foods and exercising regularly can be helpful.
7. Alzheimer’s Disease
This is a disease that destroys the memory. It affects decision-making, thinking, behaviours, and reasoning. Alzheimer’s disease is the most common type of dementia. When it progresses, you recall nothing, no memory for an extended period. An unhealthy lifestyle, getting older, and genetics can lead to it. Only a healthy diet can reduce your risk of developing this disease.

8. Diarrhea
Diarrhea is one of the leading diseases killing children. It happens when you stool for days due to bacteria that have contaminated your food, water, or by an intestinal virus. Another reason is when you live in polluted areas. The body loses water and salt when stooling becomes too much.
Maintaining healthy hygiene is the best way to prevent diarrhoea.
9. Tuberculosis
Tuberculosis is a lung disease caused by a bacteria called “Mycobacterium tuberculosis.” People with HIV infection or diabetes can quickly develop this health condition. The best prevention is to get vaccinated.
10. Cirrhosis
Cirrhosis is a condition that damages the liver. It can be caused by liver disease or hepatitis. Too much alcohol and fat accumulation are other factors that can trigger this disease. If you don’t want cirrhosis, never stop consuming nutritious foods.
