In layman term, I can say high blood pressure is when your blood travels in your vessels with more force than what is considered healthy or normal. This ‘silent killer’ disease is responsible for several illnesses and, many health issues.

In this article, I will be providing you with a complete guide on how hypertension can damage different parts of your body.

How Does Hypertension Affect The Heart?

If you do not adequately control high blood pressure, it can cause some severe damage to your heart and vessels.

Hypertension may lead to heart conditions like angina, myocardial hypertrophy and cardiac dysfunction and heart failure.

Atherosclerosis – hypertensive atherosclerotic disease

It is one of the most concerned health problems due to untreated hypertension. Atherosclerosis means the building of plaques in your arteries. Plaques narrow and harden your arteries that lead to blockage of nutrients and oxygen to your heart, causing ‘ischemic heart disease’, also known as coronary artery disease.

Heart Attack

At the early stages of the disease, you may feel chest pain as you walk or climb, which known as ‘angina’ pain. If not managed well you could experience a heart attack in the long run.


Signs of Angina or Heart Attack due to hypertension can be associated with irregular heartbeats, a condition medically known as arrhythmia.

Enlarged Heart – Myocardial hypertrophy

I would explain myocardial hypertrophy as an increase in the ventricular myocardial mass of the heart.

This condition causes the left ventricle to work hard, which eventually leads to increased heart chamber size.

Besides, the enlarged heart muscle loses its elasticity; as a result, it fails to pump with as much force as needed.

Heart failure

If you don’t control high blood pressure and its effect on the heart well, it will eventually lead to heart failure.

With time, high blood pressure would increase the strain on your heart and eventually cause the heart muscles to weaken. As the heart muscles lose their strength, they will not be able to perform efficiently. Gradually the heart will not be able to meet your body’s demand and begin to wear out and fail. Heart damage will lead to heart failure in the end.


When hypertension put constant pressure on the blood vessels, they bulge or balloon over time. This condition is called Aneurysms.

Aneurysms are common in Aorta, Arteries in the brain and arteries to internal organs.

Damage to Arteries

It is not uncommon people with uncontrolled high blood pressure require rushing to the Emergency Department due to a damaged artery. Most of the time, this condition requires immediate surgery.

Does Hypertension affect The Brain?

Raised stroke risk

If you had a ‘mini-stroke’ in the past, it is highly likely that you have high blood pressure. The best way to prevent stroke in the future is to control hypertension well.

Due to high blood pressure, there is constant stress on your brain arteries. The stress tends to damage the artery walls and makes them weaken.

Like the heart, High blood pressure harms the brain. It is responsible for causing two different effects on the brain.

Blocked blood flow

According to research, 9 out of 10 cases of stroke are because of blocked blood flow to the brain.

Blood Clots

Blood clotting speeds up arteriosclerosis, a condition in which the arteries become narrow, and they lose their flexibility, which results in accumulation of fatty plaque and blockage of arteries. Lack of oxygen to your brain leads to the death of brain cells within minutes. In this condition, your arteries This eventually leads to a stroke.

Bleeding in or around the brain

Bleeding in or around the brain is a more dangerous condition than blood clotting. You uncontrolled high blood pressure damages the arteries tear or burst them, leading to a stroke.

Sometimes high blood pressure would give you a trailer before the actual film, i.e. you might get mini-strokes.

If you do not keep a close check on your high blood pressure after these strokes, they will eventually lead to a major stroke, thus causing severe damage or death.

Memory loss

Having a memory loss could be due to the effects of your hypertension.

Mild cognitive impairment

As your brain cells slowly die due to lack of blood flow could lead to dementia or mild cognitive impairment.

If you are wondering what cognitive and dementia are, below are their definitions.


Dementia is the decline in your mental aptness with acute effect on daily life.

Mild cognitive impairment, on the other hand, is the transition stage between changes in memory and understanding. As you grow old, mild cognitive impairment can lead to Alzheimer disease, which is a serious problem. Mild cognitive is often due to blocked blood flow to the brain due to hypertension.

Does hypertension affect kidneys?

How high blood pressure damages your kidneys? Let’s find out.

If you are facing the symptoms below, I would highly recommend that you get your kidneys checked.

  1. More urine at night
  2. Difficulty in urinating
  3. Fluid retention especially in lower legs

Kidney Scarring – glomerulosclerosis

The above symptoms could be associated with kidney scarring or kidney failure.

Kidney Failure

One of the leading cause of kidney disease is hypertension. Removal of waste becomes difficult due to damage caused by hypertension to blood vessels and filters in the kidney. This eventually ends up in kidney failure.

Impact of high blood pressure on your eyes

Eye Bleeds – Choroidopathy

High blood pressure damages exquisite blood vessels that supply blood to your eyes. It narrows blood vessels, swelling of the optic nerve and macular and may cause bleeding in the back of the eye.

Vision Impairment – Hypertension Retinopathy

High blood pressure damages your retina and causes vision impairment, decrease in clarity of vision and curtain falling over your eyes. This condition is called ‘retinopathy’.

Eye signs of retinopathy include

  • Cotton wool spots or exudates
  • Swelling of the macula and optic nerve
  • Narrowing of blood vessels

Pregnancy and hypertension

Do you know what Preeclampsia and Eclampsia are?

During the second half of pregnancy, women may develop hypertension that leads to preeclampsia or more serious condition eclampsia. Preeclampsia is a condition in which you will face fluid retention or proteinuria.

Hypertension during pregnancy is dangerous for both the child and the mother. It interferes with the placenta and decreases the flow of oxygen and nutrition to the fetus. The lack of oxygen to your unborn child will cause health problems after he or she is born.

Hypertension and sexual health

Effect on men

High Blood pressure affects your sexual performance to dissatisfaction and low self-esteem. Reason being, constant high blood pressure damages your arteries, thus reducing the blood flow to your sexual organs.

Hypertension and Erectile Dysfunction

Lack of blood supply to penis leads to erectile dysfunction, which in case the man is not able to attain and sustain erection frequently. Thus, men have less sexual desire and tend to avoid sex.

Effect on Women

Low Sexual Desires

Likewise, High blood pressure could harm a woman’s sexual desires. According to studies, high blood damages the vessels taking blood to the vagina, thus disrupting the natural blood flow.

Vaginal dryness

The lack of a dissatisfied vagina leads to the decline of sexual desire. Due to arousal and vaginal dryness women, face difficulty in achieving orgasm.

Effects of hypertension on bones

Do you know hypertension even damages your bones?

Hypertension, as noted earlier, may lead to excess salts and minerals in the blood due to reduced kidney function, which can lead you to osteoporosis.


Osteoporosis can only be diagnosed when a minor fall results in a fracture requiring you to perform a scan or bone mineral density test. This disease weakens the bones and makes them flimsy.

Osteoporosis and high blood pressure could increase calcium excretion to urine; which leads to a negative balance of calcium
that predisposes a heavy bone loss.

Effect of Hypertension on sleeping

Sleep deprivation

Sleep synchronize your stress hormones that lead to a healthy nervous system. Sleep deprivation can harm your body’s power of modulating stress hormones, as time passes, this will lead to high blood pressure.

Sleep Apnea

Obstructive sleep apnea could also lead to high blood pressure. And, Sleep Apnea could intensify due to hypertension.

Effect of hypertension on legs

Leg Pains

Causes for leg pain were covered previously.


In conclusion, I can not stress the importance of controlling your blood pressure well to prevent yourself from acquiring many health problems.
