Circulatory and Cardiac System

Not all types of cholesterol is bad for your body. It’s the low density lipoprotein type or the LDL or the so called ‘BAD’ cholesterol variant, raised levels of this can put you in trouble if left unattended. It promotes the deposition of cholesterol in the Tunica Intima (inner lining of your blood vessels) of your vital blood vessels. This process is known as ‘Atherosclerosis’ and lead plaque formation and stiffening of the vessel wall.

With the progress of this pathological process the lumen size of the blood vessel keep on getting narrower. Due to this adequate amount of blood flow gets affected. Now due to this decline in the amount of blood flow the amount of oxygen supply also gets diminished.

This in turn has two effects, one the patient will develop Hypertension due to stiff arteries and secondly due to lack of adequate blood and oxygen supply, when the patient exerts he or she develops ‘Angina’ or Chest Pain. In more severe narrowing there is also a possibility of getting a Heart Attack.

An average adult human brain consumes about 25% of the total body cholesterol requirement in order to maintain functional and structural integrity. But in excess everything turns evil.

Stroke can can significant amount of physical and emotional disability.

Some studies have also found the important association between high cholesterol levels and Alzheimer’s Disease.

Endocrine System

Your endocrine system is the production house of the hormones of your body. Hormones are the chemical messengers required for the proper functioning of various glands and organs. Cholesterol is required for the production of these hormones like estrogen, testosterone etc. These hormones in turn affects your body’s cholesterol levels creating a vicious cycle.

Individuals with Hypothyroidism tends to have higher levels of Total and LDL cholesterol, whereas individuals with Hyperthyroidism have the exact opposite effect.

Digestive System

Bile is a dark green to yellowish-brown liquid produced by the liver that helps in digestion of lipids in the small intestine. In humans, bile is produced continuously by the liver and stored and concentrated in the gallbladder. Cholesterol is an important component in bile formation but too much of it in bile can also lead to formation of crystals thereby leading to gallstones.
