High Cholesterol and Statins Explained: Atorvastatin, Rosuvastatin and Side Effect Myths

A routine blood test shows that your cholesterol is high, and your doctor writes a statin. Then comes the confusion. Do I really need a tablet for life? What about the side effects I have heard about on WhatsApp? Can I manage it with diet alone? Millions of people in Pakistan are in exactly this position, and the answers are clearer than the rumours suggest.

This guide explains what cholesterol is, what your lipid profile numbers mean, how statins and other cholesterol medicines work, which side effects are real and which are myths, and the food and lifestyle steps that make a difference.

What is cholesterol?

Cholesterol is a waxy fat that your body needs to make cell walls and hormones. The liver makes most of it. Problems start when there is too much of the wrong type in the blood.

• LDL (low-density lipoprotein) is the bad cholesterol. It builds up in artery walls and forms plaque.
• HDL (high-density lipoprotein) is the good cholesterol that carries cholesterol away.
• Triglycerides are another type of blood fat. High levels add to heart risk and can cause pancreatitis when very high.

High cholesterol has no symptoms. People feel perfectly well until it contributes to a heart attack or stroke, which is why testing matters.

Your lipid profile

A lipid profile measures total cholesterol, LDL, HDL and triglycerides. Many labs ask for fasting for nine to twelve hours, although non-fasting tests are increasingly accepted. Your doctor sets your personal LDL target based on your risk. People with heart disease, a stent, stroke, diabetes or kidney disease usually need much lower LDL than healthy people. South Asians tend to have heart disease earlier, so a check from the age of 30 to 35, or earlier with a family history, is sensible.

Why it matters

Plaque narrows arteries, which can cause angina, heart attacks, strokes and poor circulation in the legs. Lowering LDL reduces these risks. See our guide to angina and heart medicines.

Statins: how they work

Statins block an enzyme in the liver that makes cholesterol. The liver then takes more LDL from the blood. They are among the most studied medicines in the world, and they lower the risk of heart attack and stroke. Common statins include:

• Atorvastatin, for example Lipitor, Stat A and Lochol.
• Rosuvastatin, for example Cougar and Xplended.
• Simvastatin, an older option.

Atorvastatin and rosuvastatin can be taken at any time of day, while some others work best in the evening. Your doctor decides the strength, and repeats the lipid test after about six to twelve weeks, then yearly.

Other cholesterol medicines

• Ezetimibe (for example Ezita) reduces the cholesterol absorbed from food. It can be added to a statin, or combined in one tablet such as Lochol EZ.
• Fenofibrate (for example Fenomax) is used mainly to lower very high triglycerides.
• Other options such as injections are for people at very high risk. Ask a specialist.

All of these are prescription medicines. See the high cholesterol category, and if you have a prescription, upload it here.

Statin side effects: facts and myths

• Muscle aches: reported by some people, but in blinded trials most of the aches turn out not to be caused by the statin. If you have severe muscle pain, weakness or dark urine, call your doctor. Do not simply stop.
• Liver: a small rise in liver enzymes is occasionally seen, and serious liver damage is very rare. Your doctor may check a liver test.
• Blood sugar: statins can raise sugar slightly. The heart protection is much greater than this risk, even for people with diabetes.
• Memory loss: there is no good evidence that statins cause lasting memory problems.
• Not safe in pregnancy: women planning pregnancy or breastfeeding should speak to their doctor.
• Interactions: some antibiotics (such as clarithromycin), antifungals and large amounts of grapefruit juice can raise statin levels. Tell your doctor about all medicines you take.

Myth: statins damage your kidneys. No, they are generally safe for the kidneys. Myth: you can stop once the number is normal. No, a normal number means the tablet is working, and it will rise again if you stop.

Food: what really helps

• Cut down on desi ghee, deep-fried food (samosa, pakora, puri), paratha, bakery items, biscuits, and fatty red meat, particularly paya and nihari. Choose oil sparingly, and grill, bake or steam.
• Eat more fibre: oats, daal, chana, rajma, whole-wheat roti, vegetables and fruit.
• Choose healthy fats: fish twice a week, nuts such as almonds and walnuts, and olive or mustard oil in moderation.
• Cut down on sugar and sweet drinks. They raise triglycerides.
• Eggs: usually fine in moderation for most people. Ask your doctor if you have heart disease.
• Limit salt to help blood pressure. See our guide to high blood pressure in Pakistan.

Lifestyle

• Walk briskly for 30 minutes on most days.
• Lose extra weight, especially around the waist. See our guide to checking weight and BMI at home.
• Stop smoking, paan, gutka and naswar.
• Limit alcohol.
• Control diabetes. See our diabetes guide.

When to see a doctor

• You have never had a lipid test and are over 30, or have diabetes, high blood pressure or a family history of early heart disease.
• You have chest pain, breathlessness, weakness on one side, or difficulty speaking. These are emergencies.
• You have severe muscle pain or dark urine on a statin.
• You are thinking of stopping your statin.
• You are pregnant or planning to be.

Frequently asked questions

Can I control cholesterol without tablets?

For mildly raised levels and low risk, diet and exercise may be enough. For people with heart disease, diabetes or very high LDL, medicines are needed in addition.

Do I have to take statins for life?

Usually yes, as long as your risk remains high. Ask your doctor to review it every year.

When is the best time to take a statin?

Atorvastatin and rosuvastatin can be taken at any regular time. Others do best in the evening. Follow your doctor’s advice.

Is high cholesterol only for overweight people?

No. Thin people can also have high cholesterol, because genes play a big role.
