What Levels in Blood is Considered High Cholesterol?

Cholesterol is waxy substance that is found in the cells of our body. It is made by our liver and is also found in several food items like meat and dairy products. While we need some amount of cholesterol for our body to function normally, too much of it in the blood can lead to health issues like coronary artery disease.

With high cholesterol, one can develop fatty deposits in the blood vessels. Ultimately, these deposits grow, thus making it tough for enough blood to flow through the arteries. Sometimes, the deposits can suddenly break and form a clot which causes a heart attack or a stroke.

While high cholesterol can be inherited, it is often due to unhealthy lifestyle choices, which can be prevented and treated.  Regular exercise and healthy diet and medication can sometimes help reduce high cholesterol.

Difference between good cholesterol and bad cholesterol

Cholesterol is transported through the blood, attached to proteins. This combination (of proteins and cholesterol) is known as lipoprotein. Lipoprotein is catergorised into different types based on what the lipoprotein carries. They include:

  • LDL or Low-density lipoprotein: Also known as ‘bad’ cholesterol, LDLcarries cholesterol particles throughout our body. LDL builds up in the walls of arteries, making them harder and narrower.
  • HDL or High-density lipoprotein: Also known as ‘good’ cholesterol, HDL, picks up excess cholesterol and takes it back to the liver.

Blood Cholesterol Levels – Table

Symptoms of high cholesterol

High cholesterol often does not show any symptoms. You may have high cholesterol levels for years without knowing about it. When your body has high cholesterol, it eventually leads to a build-up on the walls. This build-up is known as plaque which may harden over time and narrow the arteries.

This is where  health issues start. Your body needs to transfer a certain amount of blood to every organ. When the arteries get narrowed, the blood flow to the organs from the heart gets hindered and causes serious health problems. The hardened plaque may also break into pieces and lead to the formation of blood clots which completely block the flow of blood. In some cases, the arteries may get completely clogged with plaque accumulation .

A blocked artery to the heart because of either of the reasons can cause a heart attack. Similarly, a blocked artery to the brain may lead to a stroke. The only way to detect high cholesterol is through regular blood tests. Unfortunately, most people discover their high cholesterol levels only after they experience a life-threatening event.

What causes high cholesterol levels?

There are several causes of high cholesterol. They are:

  • Diet: Cholesterol is naturally produced by our liver. But we also get it from our food, especially dairy items and meat. Eating too much of these food items can cause high cholesterol in the body.
  • Lifestyle: Obesity is one of the major causes of high cholesterol. This is further complicated by inactivity which reduces the levels of HDL (good cholesterol) in the body.
  • Genetics: Your genetics can also affect your cholesterol levels. Research on the topic has indicated that cholesterol tends to run in the family, and individuals with good eating habits and active lifestyles may also have high levels of bad cholesterol.
  • Smoking: Some research studies have also found a relationship between smoking and high cholesterol.

How is high cholesterol diagnosed?

While high cholesterol does not show any clear signs and symptoms, you can get it diagnosed with a simple blood test. It is advisable that men and women above the age of 35 should get their cholesterol checked from time to time. Young individuals (20-35 years old) with high-risk factors should have their cholesterol checked by their physician to avoid heart diseases. Risk factors include:

  • Smoking
  • Inactivity
