Cholesterol Is Not a Disease in Itself

 Cholesterol Is Not a Disease in Itself

Cholesterol is a fat-like substance produced by the liver within the body. It is a vital component of the cells found in human blood.

Cholesterol is essential for the formation of healthy cells, Vitamin D, and various hormones—such as estrogen, progesterone, testosterone, cortisol, and aldosterone—as well as for the digestive process. An appropriate level of cholesterol is necessary for the body to perform various physiological functions. The mere presence of cholesterol in the body is not a danger; however, when cholesterol levels rise, the risk of chronic conditions, such as heart disease, increases.

What happens when cholesterol levels are high? How can it be controlled?

Why do cholesterol levels rise?

Factors such as genetics, an unhealthy lifestyle, excessive consumption of processed (factory-produced) foods, obesity, and pre-existing heart disease can lead to high cholesterol. Elevated cholesterol levels can cause blockages in blood vessels, potentially leading to serious heart-related problems. This also increases the risk of a heart attack. Therefore, to prevent high cholesterol, it is crucial to adopt a healthy lifestyle, maintain a nutritious diet, and engage in regular exercise.

Causes of Cholesterol Imbalance

Cholesterol itself is not a disease. Health problems arise when its balance is disrupted. Abnormal cholesterol levels—whether too high or too low—are often linked to chronic conditions such as high blood pressure, thyroid disorders, diabetes, and heart disease. These medical conditions can lead to an imbalance in cholesterol levels.

Individuals with obesity are also more likely to have high cholesterol levels. Smoking, over time, damages the heart's arteries, which contributes to an increase in cholesterol levels.

Cholesterol consists of various types of fats; specifically, it is categorized into 'good' and 'bad' types: LDL (Low-Density Lipoprotein) and HDL (High-Density Lipoprotein). An imbalance occurs when the 'good' cholesterol decreases while the 'bad' cholesterol increases.

LDL is known as 'bad' cholesterol. It transports cholesterol from the liver to the body's cells. If its levels are too high, it begins to accumulate in the cells, causing harm. Over time, LDL causes blood vessels to harden.

Conversely, HDL is considered 'good' cholesterol. It helps protect against heart-related diseases.

Causes of High Cholesterol

Nowadays, due to the lack of high-quality food—unlike in the past—the physiological processes within the body have begun to change. The excessive consumption of factory-produced food products—such as soft drinks (like Coke or Fanta) and junk food—plays a role in raising cholesterol levels.

Individuals with obesity are also more likely to have high cholesterol levels. Smoking, over time, damages the heart's arteries. This contributes to high cholesterol levels. Fluctuations in cholesterol levels and an increased risk of heart disease can lead to a heart attack, with smoking being the primary contributing factor.

Similarly, individuals with a family history of stroke or heart disease, as well as those suffering from diabetes or high blood pressure, are more likely to develop high cholesterol.

Symptoms of High Cholesterol

There are no specific symptoms to identify high cholesterol; it can only be determined through a medical examination. However, a blood test can reveal one's cholesterol status.

If heart disease develops due to cholesterol imbalances and other risk factors, the symptoms may manifest as those of a heart attack. Cholesterol is often described as a "silent killer," as its consequences—such as stroke or heart attack—frequently appear only after the condition has already taken hold.

The Misconception That Only Fatty Foods Increase Cholesterol

There is a widespread, yet incorrect, belief that consuming fatty foods is the sole cause of high cholesterol. In reality, our bodies require healthy fats. It is advisable to consult a nutritionist to identify the right types of fats and ensure a balanced intake of protein. One should not avoid fats entirely by consuming only boiled foods. Furthermore, factory-produced beverages—such as Coke or Fanta—can also contribute to an increase in cholesterol levels.

How Can High Cholesterol Be Controlled?

Adopting a healthy diet and making lifestyle changes can help control cholesterol levels. For this, it is necessary to pay attention to a few things:

- Avoid alcohol and smoking.

- Exercise regularly.

- Avoid foods made from refined flour (*maida*).

- Limit the consumption of grain-based foods.

- Avoid sugary items like sweets.

- Be mindful if you have a family history of chronic diseases.

- Include fiber-rich foods in your diet.

Cholesterol Testing

- A blood test is the only way to determine cholesterol levels. Treatment is determined based on an assessment of risk.

- When measuring cholesterol, levels of triglycerides, HDL, and LDL are checked; each plays a specific role. Generally, higher levels of HDL cholesterol and lower levels of LDL cholesterol are considered desirable. Testing is also conducted if other chronic diseases are present.

Cholesterol Medication

Cholesterol medication should be taken only upon a doctor's advice. The decision to use medication to control cholesterol depends on the individual's risk of heart disease.

If a person has diabetes, doctors may prescribe medication—even if cholesterol levels do not show significant fluctuations—to men over 40 and women who have reached menopause. Individuals who are not at risk for heart disease should focus primarily on their diet and lifestyle.
