Circulatory System Problems and Diseases

A healthy circulatory system is essential for the body, since it is responsible for supplying nutrients and oxygen to the body cells and tissues. With each heartbeat, blood is pumped into the blood vessels in order to deliver the essential nutrients required for survival to the various parts of body. Due to the importance of the circulatory system, it is often referred to as 'the lifeline of the body'.

Circulatory System: Problems and Diseases

As we all know, the circulatory system or cardiovascular system comprises the blood, heart and blood vessels. The blood consists of the red blood cells (RBCs), white blood cells (WBCs), platelets and blood plasma. The blood vessels, on the other hand, comprise the veins, arteries, arterioles and capillaries. All of these parts contribute a lot to the proper functioning of the circulatory system. A disorder in any of the parts can cause certain health complications, which may vary from a mild disease to a life-threatening condition.

There are two types of circulatory system problems, viz. congenital (present at birth) and acquired (developed after birth). Common problems and diseases of the circulatory system include:

Aortic Aneurysm: Aortic aneurysm is bulging in the wall of the aorta, the largest artery of the body. Aortic aneurysm is caused due to aortic dissection (tear in the aortic wall) or defect in the aortic wall. A rupture of the bulging may cause heavy bleeding or hemorrhage. Aortic aneurysm can be developed as a complication of certain other diseases such as obesity, atherosclerosis and high blood pressure.

Angina: Angina is pain or discomfort in the chest area, due to blockage in the blood vessels leading to the heart. The symptoms of angina are observed when there is insufficient supply of oxygen and blood to the heart. Chest pain may lasts for about 10 minutes.

Arrhythmia: Arrhythmia is a heart problem, characterized by irregularity in the heart rhythm. Symptoms may vary from very slow to fast heart rhythm. Arrhythmia can be a congenital or an acquired problem. In case of acquired arrhythmia, it can occur at any stage of life.

Atherosclerosis: Atherosclerosis is hardening of the arterial wall (usually medium and large arteries) due to formation of plaque or atheroma. The plaque may be composed of cholesterol, calcium and fatty deposits. Atherosclerosis may hamper the blood circulation or at times, it can even stop the blood flow. A person suffering from this problem experiences sharp pain in the affected area.

High Blood Pressure: High blood pressure or hypertension is a condition, when the systolic pressure exceeds 140 mmHg and diastolic pressure exceeds 90 mmHg. It is mostly caused due to hereditary reasons or unhealthy lifestyle habits such as heavy drinking and smoking.

Peripheral Vascular Disease: Peripheral vascular disease is disorder in the blood vessels that are not part of the brain and heart. This disease is caused due to fatty acid deposits in the arteries of the leg portion. It can be hereditary or develop as a complication of obesity, high blood pressure and smoking.

In severe cases, heart disease can cause heart attack, heart failure and several other fatal health problems. One word of advice for those people who smoke cigarette and have circulatory problem would be to quit smoking, as it can worsen the existing condition, by constricting the blood vessels. Circulatory problems and diseases may also be caused due to intake of certain drugs like oral contraceptives and diuretics. It is always advisable to consult and seek advice from a qualified health practitioner before using any drugs and/or medications, in order to know the pros and cons of the same.
