Disease of Circulatory System, their causes, and effects!

Fun fact about human body – in an average adult human, about 7,500 liters of blood travel daily through about 96,000 kilometers of what is known as the Circulatory System, which consists of three independent systems – the Heart (cardiovascular), the Lungs (pulmonary), and arteries & veins (systemic). In addition to blood, the Circulatory System also moves lymph, nutrients, oxygen, and hormones. Given its enormity and importance, it is highly susceptible to disease. Below are the most common diseases of the circulatory system.


This is one of the most common circulatory system ailments. Caused by the thickening and stiffening of the arteriolar walls due to the deposit of fats and cholesterol, Arteriosclerosis can restrict blood flow, resulting in a heart attack or stroke.


Also known as High Blood Pressure, this is a medical condition in which the blood pressure in the arteries is continually raised. Hypertension can cause the heart to work harder, resulting in a heart attack, a stroke, or kidney failure.

Angina Pectoris:

Symptomized by of chest pain, pressure, or squeezing, Angina Pectoris (or only Angina) is often caused by obstruction or spasm of the coronary arteries, resulting in the lack of enough blood flow to the heart. Often a result anemia or abnormal heart rhythms, Angina can eventually cause heart failure.

Cardiac Arrhythmia:

Commonly known as an irregular heartbeat, Cardiac Arrhythmia is a condition in which the heartbeat is either too fast (above 100 beats per minute), or too slow (below 60 beats per minute), with any apparent reason. Symptoms include a pause between heartbeats, lightheadedness, shortness of breath, loss of consciousness, or chest pain.

Abdominal Aortic Aneurysm:

Caused by a localized enlargement of the abdominal aorta, eventually leading to a complete rupture, this condition can lead to severe internal bleeding. The weakness of the aorta walls can be congenital or a result of hypertension, obesity, or atherosclerosis.

Peripheral Arterial Disease (PAD):

This condition is caused by a blockage in an artery, or a narrowing thereof. Another disease that has symptoms very similar to those of PAD, is Chronic Venous Insufficiency (CVI), which is characterized by a backward flow within the superficial veins of the lower extremities.

People with certain pre-existing health conditions can have a greater predisposition to the problems of the circulatory system – these conditions include diabetes, hypertension, or renal conditions. Another group of people with greater predisposition are those with certain occupational exposures, such as working with vibrating tools, cold working conditions, working in the smoky environment, etc. Smoking also can aggravate and cause circulatory disease.

The causes of the circulatory system diseases can be broadly classified into 3 categories:

Penetrating trauma

Sometimes a seemingly small cut inflicted in the wrong area can cause a major damage to the blood vessel, or a blunt injury can cause a clot in the blood vessel to stop the blood from flowing. If either of these occurs, you may even have to undergo a reconstruction surgery

Vascular malformation

An abnormal connection between the veins and arteries can cause a significant volume of blood to be redirected, resulting in pain, increased temperature, and spontaneous bleeding of the affected area. When an abnormality is too bad, you may require surgical intervention.

Vasospastic condition

When the arteries in the fingers go into spasm, they deprive the finger of blood. It often occurs when the hand is exposed to cold or tobacco, and normally the blood flow will return on its own. However, when the condition is prolonged, it can lead to tissue damage and may require surgery to separate the nerves from around the vessels to relieve the effect of the nerves causing the spasm.

Most diseases of the Circulatory System might not have any symptoms in the early stages. If the symptoms are present, they will include chest pain or a sensation of heaviness in the chest, fatigue, swollen ankles, increased urination, rapid breathing, and loss of consciousness.That said, most circulatory diseases develop over a long time and at least some of these can be managed by certain lifestyle changes, including:

  • Starting an exercise regimen
  • Controlling or losing weight
  • Secession of smoking
  • Reduced consumption of alcohol
  • Managing or reducing stress
  • Improving dietary intake

If you or a loved is showing any of the symptoms mentioned above, or if they have a sedentary lifestyle, they may be at a risk of diseases of the circulatory system. Contact us today to evaluate your health profile, and understand what lifestyle changes are needed for you.
