Causes of Heart Disease


Common Causes

Have you been wondering about what the cause of heart disease are likely to be? Apart from that when you take into consideration the fact that the heart serves to be one of the most vital organs in the body, which needs to be tended especially as you grow older, it is something that you need to take care of. It’s not a tough task though; all it would take is eating right, avoiding obesity and exercising. This could make all the difference to your heart as an adult. If you want to steer clear of this number one killer disease, then you need to keep in check a few aspects, which have been listed below, which have been discussed in detail in the following sections.

  • High cholesterol
  • Obesity
  • Smoking
  • Hereditary

High Cholesterol

One of the leading causes for heart disease is high cholesterol. This is because when fat accumulates in the blood stream and flows into the arteries. In case, you have excess cholesterol then the excess fat would stick onto artery walls, which could constrict it. This would create an interruption in the blood flow such that the blood would contain less nutrients and oxygen to the heart as well as other parts of the body. As a result it could clog the arteries with this cholesterol and this is likely to cause a heart attack. In case, the arteries aren’t healthy enough then they could very well cause blood clots, strokes and even dementia.


Another major reason which leads to heart disease is obesity. This is because weight problems give rise to higher levels of blood pressure and cholesterol, in those people who have reached the obesity stage. To be certain whether you are obese or not the doctor would measure your body mass index (BMI). The average BMI is 25 and when it is around 30, it is considered to be the obesity stage. This is a major problem that faced by both the young and the old alike. Therefore, it is essential to be healthy and fit during your youth so that it wouldn’t escalate to such a stage later on in your life.


Smoking is yet another cause of heart disease. This is because smoking increases the risk of peripheral vascular disease, which is a disease of the blood vessels. It has caused several deaths since it creates a negative impact on both the blood as well as that of the heart.


There are several people who are susceptible to heart disease since they have a history of heart disease in their family. They are more likely to have heart disease than when compared to others. Additionally, other related causes include drug abuse, diabetes, heart defects and even stress. Therefore, it is best that you go in for an annual screening to determine whether your heart is in good shape or not and at the same time take preventive measures.

These are some of the common factors causing heart disease.
