preventable. Non-preventable factors include where a person lives, access to

still steps everyone can take to lower their risk.
When people think of the deadliest diseases in the world, their minds probably
jump to the fast-acting, incurable ones that grab headlines from time to time. But
in fact, many of these types of diseases don’t rank in the top 10 causes of
worldwide deaths. An estimated 56.4 million peopleTrusted Source passed away
worldwide in 2015, and 68 percent of them were due to diseases that progressed
slowly.
Heart disease
Annual mortality rate 7.25 million
Percent of all deaths 12.8%
schemic means that an organ (e.g., the heart) is not getting enough blood and
oxygen. Ischemic heart disease, also called coronary heart disease (CHD) or
coronary artery disease, is the term given to heart problems caused by narrowed
heart (coronary) arteries that supply blood to the heart muscle.
Cerebrovascular disease
Annual mortality rate 6.15 million
Percent of all deaths 10.8
Cerebrovascular disease refers to a group of conditions, diseases, and disorders
that affect the blood vessels and blood supply to the brain. If a blockage,
malformation, or hemorrhage prevents the brain cells from getting enough
oxygen, brain damage can result.
Includes Diseases: Stroke
Lower respiratory infections
Annual mortality rate 3.46 million
Percent of all deaths 6.1
Lower respiratory tract infection (LRTI), while often used as a synonym for
pneumonia, can also be applied to other types of infection including lung abscess
and acute bronchitis. Symptoms include shortness of breath, weakness, fever,
coughing and fatigue. ... The two most common are bronchitis and edema.
Chronic obstructive pulmonary disease
Annual mortality rate 3.28 million
Percent of all deaths 5.8
Chronic obstructive pulmonary disease (COPD) is a common lung disease.
Having COPD makes it hard to breathe. There are two main forms of COPD:
Chronic bronchitis, which involves a long-term cough with mucus. Emphysema,
which involves damage to the lungs over time.
Diarrhoeal diseases
Annual mortality rate 2.46 million
Percent of all deaths 4.3
diarrhea dīərē´ə [key], frequent discharge of watery feces from the intestines,
sometimes containing blood and mucus. It can be caused by excessive
indulgence in alcohol or other liquids or foods that prove irritating to the stomach
or intestine, by allergy to certain food products, by poisoning with heavy
metals, by chemicals such as are found in cathartics, by hyperactivity of the
nervous system, and by infection with a virus (intestinal grippe) or with bacteria
or their toxins. Diarrhea is a concomitant of many infectious diseases, especially
typhoid fever , bacillary or amebic dysentery , and cholera . Persistent diarrhea
may result in severe dehydration and shock. It is therefore necessary to replace
the fluid lost by the body. Treatment is with a bland diet and drugs that will
decrease the activity of the intestines, as well as with specific measures directed
at the underlying cause. The elderly are at especially high risk for diarrheal
deaths caused by viruses. Ulcerative colitis is an inflamatory and ulcerative
disease of the colon, properly described as irritable bowl, and characterized by
bloody diarrhea. Crohn's disease affects the distal ileum and colon, but may
occur in any part of the gastrointestinal tract, from the mouth to the anus and
perianal area. The symptoms are chronic diarrhea associated with abdominal
pain, fever, anorexia, weight loss, and a mass or fullness in the right lower
quadrant (of the abdomen).
HIV/AIDS: Diagnosis & Anti-HIV Therapy
Annual mortality rate 1.78 million
Percent of all deaths 3.1
Antiretroviral therapy (ART) is the use of HIV medicines to treat HIV infection.
People on ART take a combination of HIV medicines (called an HIV treatment
regimen) every day. ART is recommended for everyone who has HIV. ... By
reducing the amount of HIV in the body, HIV medicines also reduce the risk of
HIV transmission.
Trachea, bronchus, lung cancers
Annual mortality rate 1.39 million
Percent of all deaths 2.4
Tracheal bronchus associated with lung cancer: a case report. Tracheal bronchus
is a rarely found congenital bronchial anomaly. It usually originates from the
right lateral wall of the trachea at the level < 2 cm above the tracheal bifurcation.
... It is very rare for a malignant tumor to grow from this aberrant bronchus.
Tuberculosis
Annual mortality rate 1.34 million
Percent of all deaths 2.4
Tuberculosis (TB) is a disease caused by bacteria called Mycobacterium
tuberculosis. The bacteria usually attack the lungs, but they can also damage
other parts of the body. TB spreads through the air when a person with TB of the
lungs or throat coughs, sneezes, or talks.
Diabetes mellitus
