THE TOP 10 DEAD LIST DISEASES
1. Coronary Artery Disease (Ischemic Heart Disease)
The deadliest disease in the world is coronary artery disease (CAD). CAD, also called ischemic heart disease, occurs when the blood vessels that supply blood to the heart become narrowed. The World Health Organization (WHO) estimates that about 7.4 million people died of ischemic heart disease in 2012. That was about 13.2 percent of all deaths
Among the risk factors are high blood pressure, high cholesterol, and smoking.
Regular exercise, good nutrition, and weight control can help lower your risk of developing CAD.
2. Stroke
A stroke is when an artery in the brain is blocked or leaks. Oxygen-deprived brain cells begin to die within minutes
Stroke was responsible for 6.7 million deaths around the world in 2012, according to WHO. That figure represents about 11.9 percent of all deaths. CDC figures show that nearly 130,000 people in the United States die of stroke each year — that’s one person every four minutes. About one in four strokes occur in people who have had a prior stroke. Stroke is also a leading cause of disability.
Among the risk factors are high blood pressure, high cholesterol, and smoking.
3. Chronic Obstructive Pulmonary Disease (COPD)
chronic, progressive lung disease that makes it hard to breathe. Chronic bronchitis and emphysema are types of COPD.
About 3.1 million deaths were attributed to COPD in 2012, according to WHO. That represents about 5.6 percent of deaths, a rate that has held steady since 2000. In 2004, about 64 million people around the world were living with COPD.
The main cause of COPD is tobacco — and that means secondhand smoke, too. Another factor is air pollution, both indoors and out. COPD affects men and women at about the same rate. There’s no cure for COPD.but its progression can be slowed down with medication.
4. Lower Respiratory Infections
WHO estimates that lower respiratory infections caused about 3.1 million, or 5.5 percent of deaths in 2012. This group of diseases includes pneumonia, bronchitis, and influenza.
5. Trachea, Bronchus, and Lung Cancers
Trachea, bronchus, and lung cancer are all respiratory cancers. The main causes of this type of cancer are smoking, second-hand smoke, and environmental toxins.
WHO estimates that in 2012, 1.6 million people died from trachea, bronchus, and lung cancers. These cancers represent about 2.9 percent of all deaths globally.
6. HIV/AIDS
HIV is short for human immunodeficiency virus. It’s a virus that attacks the immune system. HIV can cause AIDS, or acquired immunodeficiency syndrome. AIDS is a chronic, life-threatening condition.
According to the Foundation for AIDS Research (amfAR), since the start of the pandemic, almost 39 million people have died due to HIV/AIDS. In 2013, about 1.5 million people lost their lives to AIDS. That’s about 2.7 percent of deaths worldwide.
7. Diarrheal Diseases
Diarrhea is when you pass three or more loose stools a day. When diarrhea lasts more than a few days, your body loses too much water and salt. Death is due to dehydration. Diarrhea is usually caused by an intestinal infection transmitted through viruses, bacteria, or even parasites. This type of infection can easily spread through contaminated by water and food.
WHO estimates that 1.5 million people died from diarrheal diseases in 2012, which comprises about 2.7 percent of deaths.
8. Diabetes Mellitus
Diabetes is a group of diseases that affect insulin production and use. In type 1 diabetes, the pancreas can no longer produce insulin. The cause is not known. In type 2 diabetes, the pancreas doesn’t produce enough insulin, or it can’t be used effectively. Type 2 diabetes can be caused by a number of factors, including poor diet, lack of exercise, and carrying too much weight.
In 2012, about 1.5 million people died from diabetes-related causes, according to WHO.
9. Preterm Birth Complications
According to WHO, in 2012, as many as 1.1 million deaths were due to prematurity and complications due to low birth weight. Three-quarters of these deaths happen within the first week of life. Lack of skilled medical care makes this a huge problem in developing countries. Many newborn deaths could be avoided with good prenatal and postnatal care.
10. Tuberculosis (TB)
TB is a lung condition caused by bacteria called Mycobacterium tuberculosis. It’s an airborne disease that is often successfully treated.
In 2012, about 900,000 people lost their lives to TB, according to WHO estimates.
