How To Prevent and Treat High Cholesterol

High cholesterol poses a significant health risk for women over the age of 50. Cholesterol is a type of fat that is produced by your liver, and is essential for your body to function properly and build healthy cells.  However, when the levels in your blood become too high, it can lead to serious health problems, including heart disease, stroke, and other cardiovascular diseases. 

Understanding the causes behind this condition is crucial for prevention and effective management. 

What Is Good and Bad Cholesterol?

Did you know that there are “good” and “bad” types of cholesterol? Here are the three main ones:

1. Low-Density Lipoprotein (LDL) Cholesterol – High levels of LDL or “bad” cholesterol can increase your risk of heart disease and stroke. LDL carries cholesterol particles from your liver to various tissues and cells in your body.  However, when LDL levels are too high, excess cholesterol can accumulate in the walls of arteries, forming plaque. This plaque buildup can narrow your arteries and restrict blood flow, leading to cardiovascular problems.
2. High-Density Lipoprotein (HDL) Cholesterol – HDL, often called “good” cholesterol, helps remove excess cholesterol from the bloodstream. It then carries it back to your liver for processing and elimination. HDL acts as a scavenger, picking up excess cholesterol from your arteries and carrying it away, which helps reduce your risk of heart disease. Higher levels of HDL are considered beneficial and protective.
3. Very Low-Density Lipoprotein (VLDL) Cholesterol: VLDL is a type of lipoprotein that primarily carries triglycerides, a type of fat, from your liver to the body’s tissues. VLDL particles are the precursor to LDL. They contain more triglycerides and less cholesterol than LDL particles. As such, higher levels of VLDL are associated with an increased risk of cardiovascular disease, as VLDL particles can contribute to plaque formation when their levels are high.

It’s important to note that when discussing your levels, LDL and HDL are the primary focus, as they have the most significant impact on cardiovascular health. High LDL levels are generally considered bad, while higher levels of HDL are considered beneficial.  Therefore, maintaining a healthy balance between LDL and HDL is crucial for promoting heart health.

Causes of High Cholesterol

There are a variety of factors that can cause high cholesterol levels in women over 50, which can lead to fatty deposits developing in your blood vessels.  These deposits grow over time and make it difficult for enough blood to flow through your arteries.  Furthermore, the deposits can break without warning and form a clot that can cause a stroke or heart attack.  

The main causes include:

1. Lack of Physical Activity

This is a significant contributing factor to high cholesterol levels in women over 50. Lack of regular physical activity can lead to weight gain, decreased levels of good HDL, and increased levels of bad LDL. Engaging in regular exercise, such as brisk walking or swimming, can help improve levels and reduce the risk of cardiovascular disease.

2. Poor Diet

Unhealthy eating habits can significantly impact cholesterol levels in women over 50. Consuming foods high in saturated and trans fats, such as fried and processed foods, can raise LDL levels.  Additionally, eating too many refined carbohydrates and sugars can contribute to higher triglyceride levels. 

3. Hormonal Changes

Hormonal changes that occur during menopause can affect cholesterol in women over 50. As estrogen levels decline, there may be an increase in LDL and a decrease in HDL. This hormonal shift can lead to unfavorable changes in your lipid profile. 

4. Genetic Factors

Genetics play a significant role in determining your cholesterol levels. Some women over 50 may have an inherited predisposition to high cholesterol, known as familial hypercholesterolemia. This condition leads to elevated LDL levels and an increased risk of cardiovascular disease. Genetic testing and early intervention can aid in the management of this.

It can be inherited, but often results from unhealthy lifestyle choices, such as a diet that’s high in saturated and trans fats, cholesterol, and refined sugars.  All these can contribute to higher levels. 

5. Underlying Medical Conditions

Certain medical conditions prevalent in women over 50 can lead to high cholesterol levels. Conditions such as diabetes, hypothyroidism, and kidney disease can disrupt your body’s lipid balance, leading to higher levels.

Symptoms of High Cholesterol

A blood test is the only way to diagnose high cholesterol as it has no symptoms.  Women aged 55 to 65 should get a screening every one to two years.  Women over 65 should be tested annually.

Ranges for LDL Levels

Triglycerides

Your testing will typically measure triglycerides also.  Your blood contains triglycerides, a type of fat that acts as a source of energy.  If you have too many of them in your blood, together with low HDL and/or high LDL cholesterol levels, it can increase your risk for health problems, such as heart attack or stroke. 

High levels of triglycerides in the blood are often associated with unhealthy habits such as eating too much sugar and refined carbohydrates, drinking alcohol, being overweight or obese, and not getting enough physical activity.

How To Lower Cholesterol

Timely and appropriate treatment is crucial in managing cholesterol levels and lowering your risk of cardiovascular disease. The following treatments can help to address these issues and promote better heart health:

1. Lifestyle Modifications

Implementing positive lifestyle changes is often your first line of defense against high cholesterol. Women over 50 can benefit from:

• Adopting a heart-healthy diet: Eat nutritious foods including fruits, vegetables, whole grains, lean proteins, and healthy fats while limiting saturated and trans fats.
• Engaging in regular exercise: Incorporate aerobic activities like walking, jogging, swimming, or cycling into your routine to promote cardiovascular health.  Women over 50 should aim to exercise for at least 30 minutes a day, five days a week. 
• Maintaining a healthy weight: Shedding excess pounds through a combination of balanced eating and regular physical activity can have a positive impact on cholesterol levels.
• Limiting alcohol intake: Drinking too much alcohol can raise cholesterol levels, so it’s recommended to drink in moderation or avoid alcohol altogether.

2. Medication

In some cases, lifestyle changes alone may not be sufficient to manage high cholesterol effectively. Women over 50 may benefit from prescription medications, including:

• Statins: These medications are the most commonly prescribed type of medication for high cholesterol.  They work by blocking the production of cholesterol in the liver. Statins are also believed to lower your risk of heart disease and stroke by stabilizing plaque on artery walls and preventing certain blood clots.  
• Ezetimibe: This medication reduces the absorption of cholesterol from the diet, which lowers LDL levels.
• PCSK9 inhibitors: These injectable medications are reserved for individuals with extremely high cholesterol or those who cannot tolerate statins. PCSK9 inhibitors help lower LDL by preventing its breakdown in the liver.
• Bile acid sequestrants: These medications work by binding to bile acids in the intestine, preventing their reabsorption, and helping to eliminate cholesterol from your body.

3. Regular Monitoring

Monitoring cholesterol levels through regular blood tests is key for women over 50. This allows your doctor to assess the effectiveness of lifestyle changes and medications, making any necessary adjustments to your treatment. Routine monitoring also ensures early detection of any potential complications and provides an opportunity for timely intervention.

Women over 50 have various treatment options to manage high cholesterol levels and reduce the risk of cardiovascular disease. Maintaining a healthy balance between LDL and HDL, along with overall cholesterol management, is crucial for promoting heart health. By living a healthy lifestyle, seeking medical advice, and making informed choices, you can effectively manage your cholesterol levels and reduce your risk of cardiovascular disease.
