Let’s look at the most prevailing health risks caused by obesity:

Obesity and Heart Diseases

The more obese you are, the more prone you become to cardiovascular or heart diseases. The major reason behind this is the excess of cholesterol that damages and obstructs the normal functioning of the cardiovascular system (heart, blood vessels, and blood).

The major heart problems that obesity causes are:

  • Coronary Heart Disease

    In coronary heart disease, blood vessels that supply blood to the heart get damaged due to the deposition of cholesterol and calcium (atherosclerosis). This makes the arteries narrow and affects the blood flow. When the plaque breaks down and forms a clot, it stops the blood flow that can result in a complicated life and death situation.

    heart diseases caused by obesity

If you are obese, you should be more cautious about your heart’s health. Signs that indicate for coronary heart disease are:

  1. Fatigue
  2. Facing difficulty in breathing
  3. Frequent headache
  4. Acute chest pain
  5. Vomiting
  6. Swelling of limbs

When you experience these signs and symptoms, immediately get in touch with a cardiologist. Avail proper treatment for coronary heart disease as leaving it untreated can be life-threatening.

  • Stroke

    Sudden headache and numbing of the legs resulting in lightheadedness is called a stroke. A stroke occurs when the brain does not receive enough blood due to a blood clot in the arteries. Stroke directly indicates coronary artery disease marked by damaged arteries (atherosclerosis) and blood clots formed by disintegration (coronary thrombosis). Stroke again is a result of excess cholesterol in the body and obese people are automatically more prone to it.

  • Cardiomyopathy

    Cardiomyopathy is a heart disease in which the heart muscles have to work hard to pump the blood across the entire body (muscular abnormality of the heart). 

Symptoms to identify Cardiomyopathy are:

  1. Sudden pressure on the chest
  2. Weariness
  3. Breathlessness
  4. Flickering heartbeats
  5. Dizziness and nausea
  6. Lightheadedness

heart diseases and obesity

When the symptoms of cardiomyopathy are left untreated, it further increases the risk of developing heart failure. Sometimes the symptoms of cardiomyopathy can be so severe that the person may even die suddenly. 

  • Heart Failure

    Heart failure is yet another major health issue caused by obesity. It occurs when the heart is unable to pump enough blood to the body. It happens when the heart does not receive sufficient blood due to plaque deposits on the coronary arteries. Heart failure needs immediate medical attention as it can potentially lead to a heart attack.

    How to identify heart failure?

   The identifying symptoms of heart failure are:

  • Breathlessness on lying down
  • Coughing and wheezing
  • Swelling in the body, especially limbs 
  • Appetite loss
  • Chest Pain/ Angina
  • Frequent urination at night (Nocturia)
  • Irregular heartbeats
  • Swelling in the abdominal area
  • Coughing out the foamy mucus
  • Falling unconscious for sometime

Obesity is the primary cause of the above-mentioned heart or cardiovascular diseases. Maintain healthy eating habits and an active lifestyle to get rid of obesity and the heart risks associated with it.
