Managing High Cholesterol in Singapore

8 min read 

Introduction

High cholesterol, or hyperlipidemia, is a significant health concern in Singapore, contributing to approximately one in three deaths from coronary heart disease. With a prevalence of 39.1% among Singaporeans aged 18 to 69 in 2020, it affects more men than women and often goes undiagnosed. This article explores the nature of high cholesterol, its risks, treatment options, and the importance of medication adherence alongside lifestyle changes.

What is High Cholesterol?

Cholesterol is a waxy, fat-like substance essential for producing hormones, vitamins, and other bodily substances. Primarily produced by the liver, it is also obtained from animal-based foods. However, excessive cholesterol levels can lead to fatty deposits in arteries, impeding blood flow and increasing the risk of serious conditions like heart attacks and strokes.

Types of Cholesterol

  1. Low-Density Lipoprotein (LDL): Often called "bad cholesterol," LDL can accumulate in artery walls, narrowing them and causing blockages. High LDL levels are linked to diets high in saturated and trans fats, found in animal products (e.g., cheese, butter) and processed foods (e.g., cookies, crackers).
  2. High-Density Lipoprotein (HDL): Known as "good cholesterol," HDL transports cholesterol back to the liver for removal, reducing artery buildup.
  3. Triglycerides: These fats, formed from excess calorie intake, can also contribute to artery blockages and, in rare cases, cause pancreatitis when levels are excessively high.

Risks and Complications

High cholesterol has no noticeable symptoms, making it a silent threat that often manifests only during emergencies like heart attacks or strokes. Risk factors include:

  1. Age: Risk increases for men over 45 and women over 55.
  2. Family History: A genetic predisposition, such as familial hypercholesterolemia, elevates risk.
  3. Lifestyle Factors: Poor diet, obesity, smoking, excessive alcohol consumption, and lack of exercise contribute significantly.
  4. Medical Conditions: Type 2 diabetes and other conditions can disrupt cholesterol balance.

Untreated high cholesterol can lead to atherosclerosis (narrowed arteries), increasing the likelihood of strokes, heart attacks, chest pain, high blood pressure, chronic kidney disease, and peripheral vascular disease.

Diagnosis

A lipid panel blood test, requiring 8hrs of fasting, measures overall cholesterol, LDL, HDL, and triglyceride levels. Results vary by age, sex, and existing heart conditions. Additional tests, such as cardiovascular risk assessments, diabetes screenings, or liver function tests, may be recommended to evaluate related complications.

Treatment Options in Singapore

Managing high cholesterol involves a combination of medication, lifestyle changes, and regular monitoring. In Singapore, medications are prescription-only and available through hospitals, clinics, or online consultations with transparent pricing.

Treatment Options in Singapore
  1. Statins: The most commonly prescribed cholesterol-lowering drugs, statins (e.g., atorvastatin, rosuvastatin, simvastatin) reduce liver cholesterol production. They are recommended for:
    • Pre-existing atherosclerotic cardiovascular disease.
    • Diabetes (especially long-term cases).
    • High LDL levels (>190 mg/dL or 4.9 mmol/L).
    • Multiple cardiovascular risk factors. Statins can cause side effects like muscle aches, nausea, or digestive issues, but these are typically mild and dose-dependent.
  2. Ezetimibe: This drug reduces cholesterol absorption in the intestines and can be used alone or with statins.
  3. PCSK9 Inhibitors: Injectable options like alirocumab and evolocumab are reserved for patients intolerant to statins, enhancing liver LDL absorption.
  4. Other Medications: Bile acid-binding drugs (e.g., cholestyramine) and fibrates (e.g., fenofibrate) target cholesterol and triglyceride levels, respectively.

A local study found medication adherence to be highly effective, controlling cholesterol in up to 85% of cases compared to 10–20% for lifestyle changes alone. Despite this, myths about statins persist, deterring some patients.

Debunking Statin Myths
  1. Myth: Statins are a catch-all solution.
    Reality: Statins are prescribed selectively for high-risk patients to prevent or manage cardiovascular disease, not as a universal fix.
    • Myth: Statins cause diabetes.
      Reality: Statins may slightly elevate blood sugar in pre-diabetic individuals, but their cardiovascular benefits outweigh this risk.
    • Myth: Statins don’t prevent blood vessel disease.
      Reality: Studies show statins reduce heart attacks, strokes, and deaths by 20–40% in high-risk groups over two to five years.
    Lifestyle Modifications

    While medications are critical, lifestyle changes enhance cholesterol management:

    1. Diet: Limit saturated fats, trans fats, sodium, and sugar. Opt for lean meats, low-fat dairy, whole grains, seafood, and fiber-rich foods like oatmeal, beans, avocados, and nuts.
    2. Weight Control: Maintain a healthy BMI (18.5–24.9) to lower LDL and raise HDL.
    3. Exercise: Engage in 2.5 hours of moderate weekly exercise (e.g., brisk walking) to reduce cholesterol and blood pressure.
    4. Quit Smoking: Smoking damages blood vessels and lowers HDL.
    5. Limit Alcohol: Keep consumption to one drink daily for women and two for men to avoid raising cholesterol and triglycerides.
      Financial Considerations

      High cholesterol is a chronic condition requiring ongoing medication, monitoring, and check-ups, which can become costly. Complications like cardiovascular or kidney disease may necessitate expensive treatments or hospitalizations. Consulting a doctor ensures cost-effective, tailored treatment plans.

      Conclusion

      High cholesterol is a manageable but serious condition in Singapore, where it affects a significant portion of the population. While lifestyle changes are vital, medication adherence, particularly to statins, is the most effective control method. By combining prescribed treatments, healthy habits, and regular monitoring, individuals can significantly reduce their risk of life-threatening complications. Always consult a healthcare professional to determine the best approach for your needs.

      Medical Certificates in Singapore are recognized as long as they are issued by doctors registered by the Singapore Medical Council. Moreover, our electronic medical certificate (e-MC) will be issued using MC.GOV.SG with verifiable link and QR code.
      A valid Medical Certificate comprises the following:

      • 1. Serial number for validation of authenticity
      • 2. Type of medical leave (For example, unfit for school or duty)
      • 3. Date of issue of MC
      • 4. Duration of leave given
      • 5. Name and MCR of the Doctor (anonymous Doctors not allowed)
      • 6. Your name and identification number
      • 7. For DigiMC, ensure that it is issued from 'https://mc.gov.sg'

      No, if our Doctor has assessed that you are well and fit for work - a Medical Certificate cannot be issued.

      In general, our Doctors will issue an appropriate duration of MC that is consummate with the expected recovery period. This typically ranges between 1 to 3 days depending on the type of illness and severity. 

      Our Doctors will need to assess if an extension of MC is warranted (with or without a subsequent video consult). In some cases, where your illness is taking longer than usual to resolve, our doctor will take necessary steps to advice you further and may suggest a in-clinic review.

      A consult fee may be applicable if the doctor requires that a video consult is needed before extending your MC. Otherwise, an administrative fee of $8 will be charged for all MC extensions.

      It is illegal to buy a Medical Certificate in Singapore. A doctor will have to assess your illness over a compulsory video consult before a Medical Certificate can be issued. Thankfully, seeing a Doctor for minor ailments can be easy and straight forward - it can be done in under 5 - 10 minutes.

      Yes, in Singapore all Medical Certificates must be issued only after a proper assessment by a licensed Doctor through a consultation (whether Physical or Video call).

        During your video consult with Telemedicine doctors, they will assess your medical condition and suitability for a Medical Certificate. The doctor will also advise you on your need for medications separately.
