Diseases caused by High Blood Pressure

By , No comments
High Blood Pressure (Hypertension) is one of the worst silent killers of mankind. A number of diseases have connection with high blood pressure. Here we will discuss some diseases which are caused due to Hypertension.


  • Kidney is an organ which is worst affected by high blood pressure. Our kidney filters out the toxins out of our blood. Our blood pressure plays an important role in this filtration process. Due to high pressure the process of filtration is slowed down as arteries are narrowed and pressure of blood is increased. To overcome this condition our heart exerts even more pressure. The condition becomes worst when kidney stops functioning (Renal Failure). In that case dialysis is necessary an kidney transplant is suggested by doctors.
  • High blood Pressure can cause bleeding from arteries inside retina and it can cause blurred vision or complete vision loss. Its known as retinopathy.

    Do you have a family history of hypertension / heart attack / stroke ?



  • Coronary Artery Disease is also caused due to high blood pressure. One of the main reasons of High Blood Pressure is narrowing of arteries. It reduces the amount of blood and oxygen supply to some important organs. When Coronary Arteries (the arteries supplying blood to heart muscles) suffer from this reduced supply of blood and oxygen then its caused Coronary Artery Disease. In the worst condition it can result into heart attack or heart failure and ultimately death. Know the difference between Heart Attack and Heart Failure.
  • Blood pressure damages your arteries. When the narrowing of arteries occur, it stiffens your arteries and some fatty deposits occur inside the walls of arteries, its called arteriosclerosis. It occurs throughout the arteries in body and it can affect functioning of any organ like arms, legs, brain, kidney. There is a second way in which blood pressure hurts the arteries, its called aneurysm. In aneurysm the outer layer of arteries in cracked due to high pressure from inside and the inner lining of artery bulges out. If such bulges rupture then it can cause threat to your life.
  • Sometime blood pressure can cause damage to brain functioning. The reduce blood flow and oxygen supply can cause memory problems. Some times when some clot inside the arteries stop the blood supply to brain then ministroke or stroke can occur. Brain disease like dementia can also occur due to high BP resulting in problems with thinking, speaking, reasoning, memory, vision and movement.
  • Apart from the above discussed complications due to high blood pressure there are many more. But ultimate and most well known effect of high blood pressure is heart attack and heart failure.


We hope that after knowing about all these ill effects of high BP you will try to lower it down and help yourselves in living a health and long life.

Blood Pressure Definition and Importance in Human Anatomy

Blood Pressure Definition


Blood Pressure, in short BP, is the pressure of blood that it exerts on the walls of arteries, veins and heart chambers. Those who have lesser knowledge of biology, BP is just like air pressure inside your car tyre. Higher and lower air pressure, both are harmful for your car tyre. Similarly both higher and lower blood pressure are harmful for your body. Blood pressure is directly connected to our pulse rate and health condition of our body. Our mood also fluctuates with our blood pressure.

Readings of Blood Pressure


Most of us know that normal blood pressure is 115/70 but we don't try to know what it means. Here we will explain it.

  • Systolic Pressure: Systolic Pressure is the upper reading. Its the pressure exerted when heart contracts.
  • Diastolic Pressure: Its the lower reading. Its the pressure exerted by blood when heart is in relaxed state.

Facts about Blood Pressure



  • A person is called a patient of High Blood Pressure (Hypertension) only if his/her Blood Pressure always remains above 140/90 . Even if any one of these readings is higher then its hypertension.
  • Hypertension is a major cause of premature deaths worldwide.
  • Low Blood Pressure (Hypotension ) is the condition when any one of your blood pressure reading is below 90/60.
  • Pulmonary Hypertension is a type of blood pressure which fatal is non curable.
  • If our blood pressure falls 20 mm Hg suddenly then it can cause dizziness and fainting.
  • Generally athletes have lower blood pressure and pulse rate than any other normal human being.
  • Farting helps in lowering high blood pressure.

Causes of High Blood Pressure

  • Deposition of Cholesterol inside arteries and veins: Deposition of Cholesterol inside walls of blood vessels narrows them and the internal volume of these arteries and veins decreases. Its increases the blood pressure inside them.
  • Reduced elasticity of blood Vessels: Reduced elasticity of blood vessels causes high blood pressure. There are two main reasons behind reduced elasticity, first is smoking (either direct or passive smoking) and second is aging.

Causes of Low Blood Pressure


  • Blood Loss: Sudden Blood Loss due to some injury.
  • Pregnancy: During pregnancy ladies may have lower blood pressure due to expansion of circulatory system.
  • Heart problems: Heart Problems like low heart rate, heart fail and heart attack can cause low blood pressure.
  • Low blood sugar can cause Hypotension
  • Dehydration : During dehydration due to lack of water in body the blood volume decreases and it causes low blood pressure.
  • Anemia: Anemia can also cause low blood pressure.

Blood Pressure importance in Human Anatomy


High and Low blood pressure is not always bad. When we do some physical activity like running or exercising our blood pressure increases but returns back to normal after some time as we rest. Its bad when it does not return to normal or remains high / low when we are in resting state. However its necessary for people with good health to elevate their BP by means of physical activity sometimes as it provides strength to their heart. Thats why exercising is good for your heart.
Our Mood and Blood Pressure depends on each other. Our blood pressure can change our mood. As well as our mood can change our blood pressure. When we are angry our blood pressure increases , while if you are in some sort of depression then it can lower your blood pressure.
