cholesterol complications awareness

Overview

Cholesterol is a waxy, fat-like substance in your blood. Your body needs a small amount of it to build cells and make hormones. But when you have too much cholesterol, it can stick to the inside of your arteries, forming plaque that narrows and hardens them. This can reduce blood flow and lead to serious problems like heart attacks and strokes. Cholesterol complications refer to those health problems that can happen when high cholesterol is not managed.

Yes, high cholesterol is very common. Around one in three adults has high cholesterol, and many don't realize it.

Anyone can develop high cholesterol, but it becomes more common as you age. It also runs in families, and your risk is higher if you have an unhealthy diet, are overweight, smoke, or have conditions like diabetes or high blood pressure.

Symptoms

Common symptoms

• High cholesterol itself usually causes no symptoms.
• A fatty skin deposit called a xanthoma may appear on elbows, knees, or eyelids in some people with very high cholesterol.
• A gray-white ring around the cornea of the eye, called arcus senilis, can also be a sign, but it is common in older adults.

Symptoms in children

• Children with inherited high cholesterol usually have no symptoms either.
• In rare severe cases, cholesterol deposits may appear on the skin or around the eyes.

Symptoms in older adults

• Older adults also rarely feel symptoms from high cholesterol itself.
• They may first notice symptoms of complications, such as leg pain when walking, chest discomfort, or shortness of breath with activity.

Causes

Main causes

• Your liver makes about 75% of your blood cholesterol, and the rest comes from the food you eat.
• Eating foods high in saturated fats and trans fats can raise your cholesterol level.
• Some people inherit genes that cause their body to produce too much cholesterol, a condition called familial hypercholesterolemia.

Risk factors

• Having high blood pressure or diabetes
• Smoking or using tobacco
• Being physically inactive
• Carrying excess weight, especially around the abdomen
• Getting older (risk increases after age 40)
• Having a family history of high cholesterol or early heart disease

When to see a doctor

See a doctor urgently if:

• If you have any symptoms listed under 'callEmergency' or 'urgent', seek medical care right away. For emergency symptoms, call your local emergency number immediately.

Book a routine appointment if:

• If you are an adult over 40, ask your doctor about having a cholesterol blood test.
• If you have diabetes, high blood pressure, or a family history of early heart disease, ask about screening even if you are younger.
• If you notice fatty bumps on your skin or a gray-white ring around your eye, mention it at your next appointment.

Diagnosis

High cholesterol is diagnosed with a simple blood test called a lipid profile or lipid panel. It measures total cholesterol, LDL (the 'bad' cholesterol), HDL (the 'good' cholesterol), and triglycerides, which are another type of fat in the blood.

Tests that may be done

• Lipid profile blood test (may require fasting for 9–12 hours, but not always)
• A physical exam to look for signs like fatty skin deposits or arcus senilis
• A risk assessment that combines your cholesterol numbers with age, blood pressure, smoking status, and other risk factors

What to expect at your appointment

Your doctor or nurse will take a small sample of blood from your arm. The results are usually ready in a few days. If your cholesterol is high, your doctor will talk with you about your overall heart attack and stroke risk and discuss next steps. If you have a strong family history, you may be referred to a specialist for additional tests.

Treatment

Treatment for high cholesterol focuses on lowering your risk of heart attacks and strokes. For many people, the first step is making heart-healthy lifestyle changes. If your risk is high or your cholesterol remains elevated, your doctor may recommend cholesterol-lowering medication. The goal is always to keep your arteries clear and protect your heart and brain.

Self-care at home

• Eat a diet rich in fruits, vegetables, whole grains, and lean proteins
• Limit foods high in saturated fats, such as fatty meat, full-fat dairy, and fried foods
• Avoid trans fats, often found in some baked goods and packaged snacks
• Aim for at least 150 minutes of moderate aerobic activity per week, or as your doctor advises
• If you smoke, ask your healthcare team about support to quit
• Keep other conditions like diabetes and high blood pressure under control

Medical treatments

If lifestyle changes are not enough, your doctor may prescribe a cholesterol-lowering medicine. These medicines work by reducing how much cholesterol your body makes or by helping your body remove cholesterol from the blood. You will usually take this medication once a day, and your doctor will check your blood tests regularly to see how well it is working. It is important to take any prescribed medicine exactly as directed and never stop it without talking to your doctor.

When is surgery considered?

Surgery is not used to treat high cholesterol itself. However, if cholesterol complications have already narrowed your arteries, you may need a procedure to open them, such as angioplasty with stent placement, or bypass surgery to reroute blood flow around a severe blockage. Your heart specialist will discuss these options if they are needed.

Living with this condition

Living with high cholesterol means managing it as part of your everyday routine. Take your medications as prescribed, keep blood test appointments, and make small, consistent choices that support your heart health. You can still enjoy life — just with a little more awareness of what your heart needs.

Lifestyle tips

• Build a simple daily routine with heart-healthy meals and regular activity
• Learn to read food labels to spot hidden saturated and trans fats
• Find physical activities you enjoy, like walking, swimming, or cycling
• Manage stress through deep breathing, hobbies, or talking with friends
• Track your cholesterol numbers and other health measures like blood pressure and weight

Diet and exercise

A heart-healthy diet means eating plenty of vegetables, fruits, whole grains, beans, nuts, fish, and skinless poultry. Try to limit red meat, full-fat dairy, butter, and processed foods. For exercise, aim for moderate activity on most days — even a brisk 30-minute walk would be a great start. If you are new to exercise or have other health conditions, ask your doctor what level of activity is safe for you.

Mental health and emotional wellbeing

Being told you have high cholesterol can feel stressful or worrying, but it doesn't mean a heart attack or stroke is inevitable. Many people feel anxious when they first learn they have a health condition. It can help to focus on what you can control — like eating healthier, moving more, and taking medications if prescribed. If you feel overwhelmed or persistently anxious, talk to your healthcare provider or a mental health professional.

Prevention

High cholesterol can often be prevented or delayed with healthy lifestyle choices. Even if you have a family history, you can still reduce your risk by eating well, staying active, keeping a healthy weight, not smoking, and managing other conditions like diabetes and high blood pressure. Once you have high cholesterol, the same steps can stop it from causing further complications.

Vaccines

Staying up to date with recommended vaccines, such as the flu vaccine and COVID-19 vaccine, is important for people with high cholesterol because infections can put extra stress on the heart. Ask your local health service which vaccines are recommended for you.

Screening programmes

Regular cholesterol screening is important because high cholesterol has no symptoms. Ask your doctor about when to start screening based on your age, family history, and other risk factors. Many health systems offer routine checks every 4 to 6 years for adults with normal risk, and more often if you have existing health conditions.

Complications

If left untreated

• Heart attack, when a cholesterol plaque ruptures and blocks blood flow to part of the heart
• Stroke, when a blocked vessel reduces blood flow to part of the brain
• Peripheral artery disease, causing leg pain, numbness, and poor wound healing
• Narrowing of the arteries in other organs, which can affect the kidneys or eyes

Long-term outlook

The outlook is actually very hopeful. High cholesterol is one of the most treatable risk factors for heart disease. With lifestyle changes, medication when needed, and regular checkups, you can significantly reduce your risk of heart attack and stroke. Many people live long, full, active lives while managing their cholesterol successfully.
