Understand cholesterol, its causes, symptoms, diagnosis, treatment options, potential complications, and effective prevention strategies to maintain heart health.
What Is cholesterol?
Cholesterol is a waxy, fat-like substance found in your blood and cells. It’s essential for building healthy cells and producing hormones, vitamin D, and bile acids that aid in digestion. Your liver produces all the cholesterol your body needs, but it’s also obtained from animal-based foods like meat and dairy products.
Causes and risk factors.
High cholesterol can result from various factors:
- Unhealthy diet: Consuming saturated and trans fats found in fatty meats, full-fat dairy products, and processed foods can raise cholesterol levels.
- Lack of physical activity: Sedentary lifestyles can lower high-density lipoprotein (HDL) cholesterol, the “good” cholesterol.
- Obesity: A body mass index (BMI) of 30 or higher increases the risk of high cholesterol.
- Smoking: Cigarette smoking may lower HDL cholesterol.
- Genetics: Familial hypercholesterolemia is an inherited condition leading to high cholesterol levels from birth.
- Age and gender: Cholesterol levels tend to rise with age. Post-menopausal women might experience increased LDL cholesterol levels.
Signs and symptoms:
High cholesterol typically has no symptoms. Many individuals are unaware they have elevated levels until a serious event like a heart attack or stroke occurs. Regular blood tests are crucial to detect high cholesterol early.
Diagnosis and treatment.
Diagnosis:
A blood test called a lipid panel measures cholesterol levels, including:
- Total cholesterol
- Low-density lipoprotein (LDL) cholesterol
- High-density lipoprotein (HDL) cholesterol
- Triglycerides
Treatment:
Managing high cholesterol often involves lifestyle modifications:
- Dietary changes: Adopting a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins. Limiting saturated and trans fats is essential.
- Regular exercise: Engaging in at least 150 minutes of moderate-intensity aerobic exercise weekly can help lower cholesterol levels.
- Weight management: Losing excess weight can improve cholesterol profiles.
- Medications: In some cases, doctors may prescribe statins or other cholesterol-lowering medications to help manage levels effectively.
Complications:
If left untreated, high cholesterol can lead to:
- Atherosclerosis: Buildup of cholesterol and other substances in artery walls, causing narrowing and reduced blood flow.
- Heart Attack: Occurs when blood flow to a part of the heart is blocked.
- Stroke: This happens when blood flow to a part of the brain is obstructed.
- Peripheral artery disease: Reduced blood flow to limbs, usually the legs, leading to pain and mobility issues.
Prevention and lifestyle factors.
Preventing high cholesterol involves adopting a healthy lifestyle:
- Heart-healthy diet: Focus on plant-based foods, lean proteins, and healthy fats like those found in nuts, avocado, and olive oil. Replace red meat with lean cuts of chicken (the one part is the best as they contain far less fat), turkey cuts, and fish dishes. Reduce salt intake, as excess sodium is not good for the heart.
- Regular physical activity: Aim for at least 30 minutes of exercise most days of the week.
- Avoid smoking: Quitting smoking can improve HDL cholesterol levels and overall heart health.
- Moderate alcohol consumption: Limiting alcohol intake can help maintain healthy cholesterol levels.
When to consult a doctor.
It’s essential to consult a healthcare provider if:
- You have a family history of high cholesterol or heart disease.
- You’re overweight, smoke, or lead a sedentary lifestyle.
- You have other conditions like diabetes or high blood pressure.
Regular check-ups and open communication with your doctor can help manage and prevent high cholesterol effectively. You may be referred to a dietician or nutritionist who will assist you in losing weight. Your doctor may advocate lifestyle changes, including joining a gym, which will all contribute to your general lifestyle. Be guided by the expertise and advice dispensed by your doctor.
If you are concerned about your heart health, find and book a consultation with a healthcare professional.
