Having Hypertension can cause damage to various parts of the body

Sorry here come some of those long words

Arteries

 Arteriosclerosis. The excessive pressure in your arteries from hypertension changes the cells of the arteries' inner lining. That causes a sequence of events that make artery walls stiff and thick. This process is called arteriosclerosis (ahr-teer-e-o-skluh-RO-sis), or hardening of the arteries. It can affect arteries throughout your body, obstructing blood flow to your brain, kidneys, heart and extremities. The damage can cause chest pain (angina), heart failure, heart attack, kidney failure, stroke, peripheral arterial disease and aneurysm.

Atherosclerosis. This is the most common form of arteriosclerosis, the hardening and narrowing of your arteries that result from the aggregation of fatty clumps (plaques) and other waste material in your bloodstream.

Aneurysm. The constant pressure of blood coursing through a weakened artery over time can cause a section of its wall to enlarge and form a bulge (aneurysm). An aneurysm (AN-u-rizm) can burst and cause life-threatening internal bleeding. They can form in any artery throughout your body, but they're most common in your body's largest artery, the aorta

Heart

 Coronary artery disease (CAD). This is a collection of diseases affecting the arteries that supply blood to your heart. Changes to the cells lining these arteries reduce the capacity of the arteries to dilate and expand; this can cause chest pain (angina). Coronary artery disease also occurs when blood flow through your arteries becomes blocked, usually because of atherosclerosis. When blood can't flow freely to your heart, you can experience angina, a heart attack or irregular heart rhythms (arrhythmias). People with Hypertension who have a heart attack are more likely to die of that heart attack than are people who don't have high blood pressure.

Enlarged left heart. High blood pressure forces your heart to overwork itself. This causes the left ventricle to enlarge just as your biceps get bigger when you work out. This expansion restricts the ventricle's ability to expand sufficiently and completely fill with blood. In turn, the ventricle can't pump out as much blood to your body. This increases your risk of heart attack, heart failure and sudden cardiac death.

Heart failure. Over time, the extra work demanded by hypertension can cause your heart muscle to work less efficiently and weaken. Eventually, your overworked heart simply begins to wear out and falter. Damage from heart attacks adds to this weakness.

 Brain

Stroke. A stroke occurs when your brain is deprived of nutrients and oxygen, causing brain cells to die. Uncontrolled Hypertension can cause a stroke by weakening and damaging your brain’s blood vessels, making them narrow, leak, crack or burst. Hypertension can also cause an aneurysm. This is a bulge in the vessel wall that can break off or burst, cutting off blood flow to the brain and leading to stroke.

Transient ischemic attack. Sometimes called a ministroke, a transient ischemic (is-KEM-ilk) attack is a brief, temporary obstruction of blood supply to your brain. It's often caused by atherosclerosis or a blood clot — both of which can arise from high blood pressure. A transient ischemic attack is often a warning that you're at risk of a full-blown stroke.

Dementia. Dementia is a mental disorder that impairs thinking, speaking, reasoning, memory, bladder control, vision and movement. Vascular dementia can result from extensive narrowing and blockage of the arteries that supply blood to the brain. It can also result from strokes caused by an interruption of blood flow to the brain. In either case, high blood pressure may be the culprit. High blood pressure that occurs even as early as middle age can lead to dementia in later years.

Mild cognitive impairment. Mild cognitive impairment is a transition stage between the cognitive changes of normal aging and the more serious problems caused by Alzheimer's disease. Like dementia, it can result from impaired blood flow to the brain when high blood pressure damages arteries. This condition can affect many areas of cognition, such as language, attention, critical thinking, reading, writing, reaction time and memory.

Kidneys

 Kidney failure. Hypertension is one of the most common causes of kidney (renal) failure. That's because it can damage both the large arteries leading to your kidneys and the tiny blood vessels (glomeruli) within the kidneys. Damage to either disrupts the ability of your kidneys to filter waste products from your blood. As a result, dangerous levels of fluid and waste can accumulate. You might ultimately require dialysis or kidney transplantation.

Glomerulosclerosis. Glomerulosclerosis (glo-mer-u-lo-skluh-RO-sis)) is a type of kidney damage caused by scarring of the glomeruli (glo-MER-u-li). The glomeruli are tiny blood vessels within your kidneys that filter fluid, waste and other substances from your blood. Glomerulosclerosis can leave your kidneys unable to filter waste effectively, ultimately leading to kidney failure.

Kidney aneurysm. An aneurysm is a bulge in the wall of a blood vessel. When it occurs in an artery leading to the kidney, it's known as a kidney aneurysm. One potential cause is atherosclerosis, which weakens and damages the artery wall. Over time, the excessive pressure of blood coursing through a weakened artery can cause a section to enlarge and form a bulge — the aneurysm. Aneurysms can rupture and cause life-threatening internal bleeding.

Eyes

 Retinopathy. High blood pressure can damage the vessels supplying blood to your retina. Damaged enough, the blood vessels can leak or become blocked, resulting in retinopathy. This condition can lead to bleeding in the eye, microaneurysms, swelling of the head of the optic nerve, blurred vision and complete loss of sight. If you also have diabetes along with high blood pressure, you're at an especially increased risk of diabetic retinopathy.

Choroidopathy. In this condition, fluid accumulates under the retina because of a leaky blood vessel in the choroid, a layer of blood vessels located under the retina. Choroidopathy (kor-oid-OP-uh-the) can result in vision distortion or in some cases scarring that impairs vision.

Optic neuropathy. This is a condition in which the optic nerve sustains damage because its blood supply is blocked. It can lead to the death or dysfunction of optic nerve cells, which may cause bleeding within your eye or vision loss.

Other

 Sexual dysfunction. Although the inability to have and maintain an erection (erectile dysfunction) becomes increasingly common in men as they climb past age 50, it's even more likely to occur if they have high blood pressure, too. Evidence linking high blood pressure to sexual dysfunction in women isn't conclusive.

Bone loss. High blood pressure can increase the amount of calcium that's eliminated in the urine. That excessive elimination of calcium may lead to loss of bone mineral density (osteoporosis), which in turn can lead to fractures. The risk is especially increased in older women.

 OK I hope I convinced you – get your blood pressure checked now.
