High cholesterol is one of the most common risk factors for heart disease and stroke, yet it often develops silently without causing noticeable symptoms. In fact, many people only discover they have high cholesterol after routine blood work or after experiencing a cardiovascular event such as a heart attack or stroke.
The encouraging news is that high cholesterol is often preventable and manageable. Understanding what high cholesterol is, recognizing the factors that contribute to it and knowing when to be tested are important steps toward protecting your long-term cardiovascular health.
As a Naturopathic Doctor and primary care healthcare provider with nearly 20 years of clinical experience, I regularly help patients assess their cardiovascular risk, interpret cholesterol test results, investigate the underlying causes of elevated cholesterol and develop personalized strategies to improve heart health.
What is high cholesterol?
One of the most common questions patients ask is, "What is high cholesterol?" Cholesterol is a waxy, fat-like substance that is naturally produced by the liver and is also obtained from certain foods. Your body needs cholesterol to produce hormones, vitamin D, bile acids and the membranes surrounding every cell.
Problems arise when cholesterol levels become too high, particularly low-density lipoprotein (LDL) cholesterol, often referred to as "bad cholesterol." Excess LDL cholesterol can accumulate within the walls of arteries, contributing to the development of atherosclerosis (hardening and narrowing of the arteries).
Over time, this increases the risk of:
- Heart attack
- Stroke
- Peripheral artery disease
- Other cardiovascular conditions
Not all cholesterol is harmful. High-density lipoprotein (HDL) cholesterol, sometimes called "good cholesterol," helps transport excess cholesterol back to the liver for removal.
What causes high cholesterol?
Many people ask, "What causes high cholesterol?" There is rarely a single cause. Instead, elevated cholesterol usually results from a combination of genetics, lifestyle and underlying medical conditions.
Common causes of high cholesterol include:
- Diet high in saturated or trans fats
- Obesity
- Physical inactivity
- Smoking
- Excess alcohol consumption
- Diabetes
- Hypothyroidism
- Chronic kidney disease
- Certain medications
- Family history of high cholesterol
- Increasing age
For many individuals, genetics play a major role regardless of how healthy they eat.
What causes high cholesterol in women?
Patients often ask, "What causes high cholesterol in women?" While many causes are shared by both men and women, several female-specific factors can influence cholesterol levels.
These include:
- Pregnancy
- Menopause
- Declining estrogen levels
- Polycystic ovary syndrome (PCOS)
- Hypothyroidism
- Certain hormonal medications
Estrogen generally has a favourable effect on cholesterol. As estrogen declines during menopause, LDL cholesterol often rises while HDL cholesterol may decrease, contributing to increased cardiovascular risk.
The most common causes of high cholesterol include genetics, poor diet, obesity, physical inactivity, diabetes, hypothyroidism and hormonal changes such as menopause.
What can cause a sudden increase in cholesterol?
Some patients are surprised when cholesterol levels rise significantly between routine blood tests and ask, "What can cause a sudden increase in cholesterol?" Several factors may contribute, including:
- Weight gain
- Reduced physical activity
- Dietary changes
- Menopause
- Pregnancy
- Poorly controlled diabetes
- Untreated hypothyroidism
- Certain medications (such as corticosteroids or some hormone therapies)
- Acute illness or inflammation (occasionally affecting test results)
A sudden change should prompt a discussion with your healthcare provider to identify any underlying cause.
How do you know if you have high cholesterol?
One of the challenges with high cholesterol is that it usually causes no symptoms.
The only reliable way to know is through a blood test called a lipid profile, which measures:
- Total cholesterol
- LDL cholesterol
- HDL cholesterol
- Triglycerides
Routine cholesterol screening is recommended for many adults, particularly those with cardiovascular risk factors or a family history of heart disease.
Symptoms of high cholesterol
People frequently search for symptoms of high cholesterol, but this can be misleading.
In most cases: High cholesterol does not cause symptoms. Instead, elevated cholesterol quietly contributes to plaque formation inside arteries over many years. When symptoms eventually occur, they are usually caused by reduced blood flow to organs rather than the cholesterol itself.
Examples include:
- Chest pain (angina)
- Heart attack
- Stroke
- Peripheral artery disease
This is why regular screening is so important.
Symptoms of high cholesterol in females
Many people specifically search for symptoms of High Cholesterol Treatment or diagnosis in females. The reality is that women generally experience the same lack of symptoms as men.
However, women may develop symptoms once cardiovascular disease becomes established, including:
- Chest discomfort
- Shortness of breath
- Fatigue during exertion
- Reduced exercise tolerance
Women may also experience less typical symptoms during heart attacks, making cardiovascular risk assessment particularly important.
Signs of high cholesterol
Patients often ask about the signs of high cholesterol. Although cholesterol itself rarely causes symptoms, certain physical findings may occasionally occur, particularly in people with inherited cholesterol disorders.
These include:
- Yellow cholesterol deposits around the eyelids (xanthelasma)
- Cholesterol deposits over tendons (xanthomas)
- A pale ring around the coloured part of the eye (corneal arcus), especially in younger individuals
These findings are relatively uncommon and should always be assessed by a healthcare professional.
What are 10 warning signs of high cholesterol?
One of the most common questions online is, "What are 10 warning signs of high cholesterol?" The most important point is that there are no reliable early warning signs of high cholesterol itself. Instead, many of the symptoms people associate with high cholesterol actually reflect advanced cardiovascular disease.
Possible warning signs of complications include:
- Chest pain (angina)
- Shortness of breath
- Heart attack
- Stroke symptoms
- Pain in the legs while walking (claudication)
- Yellow cholesterol deposits around the eyes
- Tendon xanthomas
- Erectile dysfunction related to vascular disease
- Transient vision loss or neurological symptoms
- Family history of premature heart disease or inherited high cholesterol
These signs warrant prompt medical evaluation.
Side effects of high cholesterol
Although cholesterol itself does not usually produce symptoms, the side effects of high cholesterol develop gradually as plaque builds within arteries.
Potential long-term consequences include:
- Coronary artery disease
- Heart attack
- Stroke
- Peripheral artery disease
- Kidney disease related to vascular damage
- Reduced circulation
- Cognitive impairment related to vascular disease
These complications often develop silently over many years.

How is high cholesterol diagnosed?
Diagnosis is made using a fasting or non-fasting lipid profile. Your healthcare provider may also assess:
- Blood pressure
- Blood sugar
- Body weight
- Family history
- Smoking status
- Physical activity
- Overall cardiovascular risk
Rather than focusing on cholesterol alone, modern cardiovascular prevention considers a person's overall risk profile.
Can high cholesterol be improved?
Yes. For many people, cholesterol levels can improve through a combination of:
- Healthy dietary patterns
- Regular physical activity
- Weight management when appropriate
- Smoking cessation
- Managing diabetes and blood pressure
- Appropriate medications when indicated
The most effective treatment depends on the underlying cause and each individual's overall cardiovascular risk.
The Naturopathic approach to high cholesterol
Naturopathic Doctors are highly trained primary care healthcare professionals who are well-equipped to evaluate cardiovascular risk and investigate the underlying contributors to high cholesterol.
Rather than focusing solely on cholesterol numbers, NDs assess nutrition, physical activity, sleep, stress, body weight, metabolic health, thyroid function, family history, inflammation and other factors that influence long-term cardiovascular health. When appropriate, we work collaboratively with family physicians and cardiologists to ensure patients receive comprehensive, evidence-informed care.

FAQ’s
What is the main cause of high cholesterol?
The main cause of high cholesterol is often a combination of lifestyle, genetics, age and underlying health conditions. Diets high in saturated fat, low physical activity, smoking, obesity, diabetes, thyroid problems, kidney disease, certain medications and family history can all raise LDL cholesterol. Inherited conditions such as familial hypercholesterolemia can also cause very high cholesterol even in people who eat well.
What are 10 warning signs of high cholesterol?
High cholesterol usually has no clear warning signs, which is why a blood test is the only reliable way to know your levels. However, long-term high cholesterol can contribute to plaque buildup in the arteries and may lead to warning signs of heart or circulation problems, such as chest pain, shortness of breath, leg pain while walking, numbness, weakness, dizziness, sudden vision changes, confusion, severe headache, or signs of a heart attack or stroke.
What do you feel if your cholesterol is high?
Most people feel nothing when their cholesterol is high. High LDL cholesterol can slowly build plaque inside arteries without obvious symptoms for years. Some people with genetic high cholesterol may develop fatty deposits on the skin or around the eyes, but this does not happen to everyone. Regular lipid blood testing is important, especially if you have risk factors or a family history.
What reduces cholesterol quickly?
Cholesterol is usually reduced through a combination of heart-healthy eating, regular physical activity, weight management when needed, quitting smoking, limiting alcohol and medication when prescribed. Statins and other cholesterol-lowering medicines may lower LDL more effectively and quickly than lifestyle changes alone, but they should be used under medical guidance. For diet, increasing soluble fiber and reducing saturated fat can support healthier cholesterol levels.
How to remove cholesterol from the body?
You cannot “flush out” cholesterol with a cleanse or one drink. The body naturally processes cholesterol through the liver and LDL levels are lowered by reducing intake of saturated fats, increasing fiber-rich foods, staying active, managing weight, treating related conditions and using medication if recommended. The goal is not to remove all cholesterol, because the body needs some cholesterol, but to keep LDL and overall cardiovascular risk in a healthier range.
Final thoughts
High cholesterol is one of the most important modifiable risk factors for cardiovascular disease, yet it often develops without noticeable symptoms. Understanding what is high cholesterol, recognizing the causes of high cholesterol and undergoing regular screening are essential steps toward protecting your heart.
If you have risk factors such as diabetes, obesity, high blood pressure, a family history of heart disease, or are approaching menopause, consider discussing cholesterol testing with your healthcare provider. As a primary care Naturopathic Doctor, I help patients identify the underlying contributors to elevated cholesterol and develop individualized strategies that support long-term cardiovascular health while reducing the risk of future heart disease.
