What is the greatest risk of death worldwide?

High blood pressure

High blood pressure is one of the greatest risks of death worldwide. High blood pressure causes 7.5 million deaths, which is about 12.8% of all deaths. This accounts for 57 million disability adjuster life years (also known as DALYS) or 3.7% of DALYS. Raised blood pressure is a major risk factor for coronary heart disease and ischemic as well as a hemorrhagic stroke. Blood pressure levels have been shown as positively and continuously related to the risk of a stroke or a coronary heart disease. In several age groups, the risk of cardiovascular disease doubles for each increment of 20/10 mmHg of blood pressure, starting as low as 115/75 mmHg. In addition to coronary heart disease and stroke, complications of raised blood pressure include heart failure, peripheral vascular disease, renal impairment, retinal hemorrhage, and visual impairment. Treating systolic blood pressure until they are less than 149/90 mmHg is associated with a reduction in cardiovascular complications.

•strokes

•Heart attack, which can be fatal

•brain damage such as cognitive impairment or dementia

•Kidney damage or kidney failure

•Damaged arteries, which can lead to an aneurysm

•heart damage such as enlarged left heart or coronary artery disease

•and more

•Fatigue and confusion- those who suffer feel dazed and unable to think as they normally would.

•Headaches- often severe and debilitating headaches.

•Irregular heartbeat- heartbeat may pump at a rate different than normal.

•vision issues- people may have blurry vision when having high blood pressure.

•shortness of breath- This will often occur at surprisingly times at rest instead of just heavy physical exertion.

Primary (essential) hypertension

for most adults, there's no identifiable cause of high blood pressure. This type of high blood pressure tends to develop gradually over many years.

Secondary hypertension

some people have high blood pressure caused by an underlying condition. this type of high blood pressure tends to appear suddenly and cause higher blood pressure than does primary hypertension. Various conditions and medications can lead to secondary hypertension, including:

•obstructive sleep apnea

•kidney problems

•thyroid problems

•adrenal gland tumors

•certain defects you're born with (congenital) in blood vessels.

•illegal drugs, such as cocaine and amphetamines.

•certain medications, such as birth control pills, cold remedies, decongestants, over the counter pain relievers and some prescription drugs.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
