Top 5 Deadliest Disease
Many of the world’s deadliest
diseases can be prevented. Knowing what they are may be just the inducement you need to take precautionary measures.
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 conical. 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 danger factors are high blood pressure, high cholesterol, and smoking. Regular exercise, good
nutrition, and weight control
can help lower your risk of developing CAD.
7.4 million people died from coronary heart disease in 2012. 13.12% of all deaths.
2. Stroke
A stroke occurs when artery is blocked or 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.
Risk factors for stroke are
similar to those for CAD. In
general, good health habits can
lower your risks. Stroke is the 4th leading cause of death in the US,
with one person dying every 4 minutes as a result. Approximately 800,000 people have a stroke each year;
about one every 4 seconds. Only
heart disease, cancer and chronic lower respiratory diseases are
more deadly.
Strokes occur due to problems
with the blood supply to the brain; either the blood supply is blocked or a blood
vessel within the brain ruptures.
A stroke is a medical emergency, and treatment must be sought as quickly as
possible.
There are three main kinds of
stroke; ischemic strokes, hemorrhagic strokes and transient ischemic attacks (TIAs), also
referred to as mini-strokes.
3. Chronic Obstructive Pulmonary Disease
(COPD)
COPD is a 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.
The American Lung Association
estimates that in 2011, 12.7 million
adults in the United States had COPD, but even more showed some sign of lung problems. There’s a great variation in the number of cases
from state to state. In 2011, about 4
percent of people in Minnesota and Washington had COPD. In Alabama and
Kentucky, it was more than 9
percent.
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. Flu
season lasts from December through February in the Northern Hemisphere and from June through August in the Southern Hemisphere. The risk is year
round in tropical regions.
According to the CDC, about 20 percent of travelers returning to
the United States seek medical attention for respiratory infection following a trip. Packed cruise ships, hotels, and other close quarters increase risk of
transmission and outbreaks of
disease.
5. Trachea, Bronchus, 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.
