4 Impacts of Untreated High Cholesterol, Don't Take It Lightly!

Cholesterol is a fatty substance naturally produced by the body and also obtained from food. In normal amounts, cholesterol plays an important role in forming cell membranes, producing hormones, and helping form vitamin D. However, when cholesterol levels, especially LDL (Low-Density Lipoprotein) cholesterol, are too high, this condition can pose a serious threat to health.

Unfortunately, high cholesterol is often referred to as a silent disease because it generally doesn't cause symptoms in its early stages. Many people only discover they have high cholesterol after undergoing a medical examination or even after experiencing complications such as a heart attack or stroke.

If left untreated, high cholesterol can lead to plaque buildup in the blood vessels, known as atherosclerosis. This buildup impedes blood flow and increases the risk of various dangerous diseases.

So, what are the effects of untreated high cholesterol? Here's a complete explanation.

1. Increased Risk of Coronary Heart Disease

One of the most serious impacts of untreated high cholesterol is an increased risk of coronary heart disease. This disease occurs when the coronary arteries, which supply oxygen-rich blood to the heart muscle, become narrowed due to the buildup of cholesterol plaque. This plaque is made up of LDL (Low-Density Lipoprotein) cholesterol, fat, and other substances that stick to the artery walls over time.

In the early stages, narrowing of the arteries often causes no symptoms, so many people are unaware of the condition. However, as the plaque increases in size, blood flow to the heart is reduced. As a result, the heart muscle does not receive enough oxygen and nutrients to function optimally, especially during physical activity that requires a greater blood supply.

This condition can cause various symptoms, such as chest pain or angina, shortness of breath, fatigue during activity, and irregular heartbeats. In some people, symptoms may only occur during exercise or strenuous activity, then subside when resting. However, if the narrowing worsens, symptoms can occur even when inactive.

The greatest danger arises when the cholesterol plaque ruptures. Plaque rupture can trigger the formation of a blood clot, completely blocking blood flow. If the blockage occurs in a coronary artery, oxygen supply to the heart muscle will be cut off, causing a heart attack. This condition is a medical emergency that requires immediate treatment to prevent permanent damage to the heart muscle or even death.

The risk of coronary heart disease increases if high cholesterol is combined with other factors, such as high blood pressure, diabetes, obesity, smoking, lack of exercise, and a diet high in saturated and trans fats.

To reduce this risk, it's important to adopt a healthy lifestyle from an early age. Start by limiting your consumption of fatty foods and increasing your intake of fruits, vegetables, whole grains, and fish rich in omega-3s.

Additionally, get at least 150 minutes of moderate-intensity exercise per week, maintain a healthy weight, quit smoking, and have your cholesterol levels checked regularly. If lifestyle changes don't control your cholesterol levels, your doctor can prescribe cholesterol-lowering medication, which should be taken as directed.

2. Causes Stroke

High cholesterol is a major risk factor for ischemic stroke, a type of stroke that occurs due to a blockage in blood flow to the brain. This condition develops slowly as LDL (Low-Density Lipoprotein) cholesterol builds up on blood vessel walls. This buildup forms plaque, which narrows the blood vessels and reduces blood flow to brain tissue.

The mechanism of stroke caused by high cholesterol is almost the same as coronary heart disease. The difference is that the blockage occurs in the blood vessels that supply oxygen and nutrients to the brain. When the plaque enlarges or ruptures, the body forms a blood clot as a natural response. This blood clot can partially or completely block the blood vessel. If blood flow is interrupted, brain cells are deprived of oxygen and begin to suffer damage within minutes. The longer the brain is deprived of blood supply, the more extensive the damage can be.

Stroke symptoms usually appear suddenly and should not be ignored. Some of the most common signs include a face that appears to skew to one side, difficulty speaking or slurred speech, numbness on one side of the body, sudden weakness in the arms or legs, impaired vision in one or both eyes, and severe dizziness accompanied by loss of balance. In some cases, sufferers may also experience confusion, difficulty understanding speech, and even loss of consciousness.

Stroke is a medical emergency that requires immediate treatment. Prompt treatment can help reduce brain tissue damage, improve the chance of recovery, and lower the risk of permanent disability or death. Therefore, anyone experiencing stroke symptoms should be taken to the hospital immediately without waiting for symptoms to improve on their own.

The risk of stroke due to high cholesterol can be reduced by consistently adopting a healthy lifestyle. Some steps that can be taken include regularly checking cholesterol levels, maintaining normal blood pressure, controlling blood sugar levels, especially for diabetics, quitting smoking, and limiting consumption of fast food, which is generally high in saturated fat, trans fat, salt, and calories.

In addition, increase your consumption of fruits, vegetables, whole grains, and fish, which are rich in omega-3 fatty acids. Regularly exercising at least 150 minutes per week, maintaining a healthy weight, and following your doctor's medication recommendations also play a vital role in controlling cholesterol levels. By taking these steps, you can significantly reduce the risk of stroke while maintaining long-term blood vessel and brain health.

3. Peripheral Artery Disease

High cholesterol not only increases the risk of heart disease and stroke, but can also lead to peripheral artery disease (PAD). This condition occurs when cholesterol plaque builds up in the arteries that supply blood to parts of the body other than the heart and brain, particularly the legs and, in some cases, the hands. Plaque buildup narrows the blood vessels, reducing the blood flow that carries oxygen and nutrients to the body's tissues.

In its early stages, peripheral artery disease often causes no obvious symptoms. However, as the blockage progresses, sufferers may begin to experience pain or discomfort in the legs when walking or exercising. This discomfort usually subsides after rest and returns with activity. This condition is known as claudication, or pain caused by reduced blood flow to the muscles.

In addition to pain when walking, peripheral artery disease can also cause other symptoms such as calf cramps, feet feeling cold compared to the rest of the body, numbness, tingling, slow-healing wounds, slowed nail growth, and pale or bluish skin discoloration. In some sufferers, leg hair loss can also occur due to impaired blood circulation.

If left untreated, the narrowing of the blood vessels will worsen and cause prolonged oxygen deprivation of body tissues. This can lead to tissue damage or death, a condition known as gangrene. In very severe cases, doctors may need to perform amputation to prevent the spread of infection and save the patient's life.

The risk of peripheral artery disease is higher in people with high cholesterol, diabetes, hypertension, obesity, smoking, and advanced age. Therefore, it is important to recognize the symptoms early so that treatment can be initiated before more serious complications occur.

Preventing peripheral artery disease can be done by maintaining normal cholesterol levels through a balanced diet, reducing saturated and trans fat consumption, increasing high-fiber foods, and exercising regularly for at least 150 minutes per week. Furthermore, quitting smoking, maintaining a healthy weight, controlling blood pressure and blood sugar, and undergoing regular health checkups are also crucial. If your doctor prescribes cholesterol-lowering medication or other therapies, be sure to take them as directed to maintain blood vessel health and minimize the risk of complications.

4. Impaired Function of Other Organs

Long-term, untreated high cholesterol can not only impact the heart, brain, or blood vessels in the legs, but can also disrupt the function of various other vital organs. This occurs because the buildup of cholesterol plaque in the blood vessels can obstruct blood flow, which carries oxygen and nutrients to the body's organs. If this condition persists, organ function will gradually decline and increase the risk of various health complications.

One organ that is susceptible to damage is the kidney. This organ filters waste and excess fluid from the blood before it is excreted through urine. When the blood vessels supplying the kidneys become narrowed due to the buildup of cholesterol plaque, blood flow to the kidneys is reduced. As a result, the kidneys' ability to filter blood can slowly decline. If left untreated, this condition can progress to chronic kidney disease, which requires long-term treatment.

High cholesterol can also affect eye health. Narrowing of the blood vessels that supply blood to the retina can reduce the supply of oxygen and nutrients needed by eye tissue. In the long term, this condition has the potential to cause retinal damage, characterized by decreased vision, blurred vision, and an increased risk of permanent vision loss if not promptly treated.

Furthermore, excessive cholesterol levels are also linked to the formation of gallstones. Bile contains cholesterol, which aids in fat digestion. However, if cholesterol levels in bile are too high, it can precipitate and form crystals that eventually develop into gallstones. This condition can cause severe pain in the upper right abdomen, nausea, vomiting, and even digestive problems.

It's important to understand that not everyone with high cholesterol will experience these complications. However, the risk increases if cholesterol levels have not been controlled for years, especially if accompanied by diabetes, hypertension, obesity, or smoking.

Therefore, maintaining normal cholesterol levels through a healthy diet, regular exercise, maintaining a healthy weight, and regular health checkups are important steps to protect the function of various organs and prevent more serious complications later in life.

Conclusion

High cholesterol is not a condition to be taken lightly, as it often develops without symptoms. If left untreated, it can lead to various serious complications, such as coronary heart disease, stroke, peripheral artery disease, and other organ dysfunction.

The good news is that most of the effects of high cholesterol can be prevented through a healthy diet, regular exercise, maintaining a healthy weight, quitting smoking, and regular health checkups. If necessary, follow your doctor's recommended treatment to keep your cholesterol levels under control and minimize the risk of complications.
