Stroke Top Famous Deadly Diseases Known to Man 2019

A stroke will occur when an artery in the brain becomes blocked or begins to leak. This causes oxygen to be deprived of brain cells which begin to die within minutes. In 2012, strokes were the leading cause of death for millions. The CDC (Center for Disease Control and Prevention), estimates almost 130,000 people in just the U.S. die from strokes every year.

Black persons are more likely to die from a stroke over those of the whites. Those of Hispanics ethnicity fall somewhere in-between those of the black person and whites. No matter what your race or ethnicity, the risks for strokes come from high blood pressure, smoking, and high cholesterol. It is estimated that approximately half of all Americans suffer from at least one of these risk factors.

9. Lower Respiratory Infections


Diseases included under the lower respiratory infections classification are; bronchitis, influenza, and pneumonia. The flu season will last from December through February when it affects the most amounts of people at one time in the Northern Hemisphere. In the Southern Hemisphere, that season is June through August. In tropical areas, the risk of becoming infected are year round. The CDC reports approximately 20 percent of the travelers coming back into the U.S. after a foreign vacation need to seek medical attention for a respiratory infection.

The most common cause of lower respiratory infections is viral pathogens. Outbreaks are commonly associated with cruise ships, hotels, and tour groups. The air-pressure changes when a plane takes off or comes in for landing are common causes for the development of sinusitis and otitis media. You are at risk for direct airborne transmissions when flying even though air is filtered and recirculated, it is not fool-proof and often spreads these lower respiratory infections. These infections are preventable with vaccines available through your physician.

TB can spread through your lymph nodes and bloodstream to affect any organ in your body. It most commonly found in a person’s lungs. The bacteria can live in a person’s body for years and never surface with symptoms until their immune system is weakened.

This is one of the Top 10 Deadly Diseases Known to Man 2017.

5. Preterm Birth Complications


Preterm Birth Complications are responsible for as many as 1.1 million deaths in just one year.

The general cause of these deaths is mainly resulting from poor medical care and is a huge problem in developing countries. Many of these deaths could have been prevented with the proper prenatal and postnatal care. Being born too early can cause short-term and long-term health problems for preemies. The baby’s weight at birth plays a large part in these complications.

Complications arising from preterm birth are problems with; breathing, heart, brain, temperature control, gastrointestinal, blood, metabolism, and immune systems. These are the short-term complications. There are long-term complication problems also which are; cerebral palsy, impaired cognitive skills, vision, hearing and dental problems.

3. Trachea, Bronchus, and Lung Cancers


Trachea, Bronchus, and Lung Cancers are all diseases that affect the respiratory system. Their main cause is environmental toxins, second-hand smoke, and smoking. These diseases are responsible for approximately 2.9 percent of all deaths each year around the globe. Lung cancer is an uncontrolled cell growth within the tissue of the lungs. When it goes untreated, it will metastasis into tissue near it and other parts of the body.

The main reason for lung cancer is due to long-term tobacco smoking. Some cases are a result of genetic factors and those who have had exposure to asbestos, radon gas, air pollution, and second-hand smoke.
