Different type of Cholesterol
Cholesterols are transported in our bloodstream through proteins known as lipoproteins. There are 2 main lipoproteins in our body:
Cholesterols are fat particles. They are important in generating cell membrane, vitamin D, hormones in our body and plays a role in production of bile salt. Cholesterol can either be made from our liver, or we can acquire cholesterol from our diet.
Cholesterols are transported in our bloodstream through proteins known as lipoproteins. There are 2 main lipoproteins in our body:
LOW DENSITY LIPOPROTEIN (LDL)
While LDL transports cholesterols to cells in different part of our body, when there is excessive amount of LDL, it can build up in the walls of our blood vessels. These fat deposits, also known as plaques, overtime can narrow the blood vessel diameter, restrict blood flow to vital organs of our body such as the heart, brain, muscles, limbs. LDL is termed as the ‘bad cholesterol’.
HIGH DENSITY LIPOPROTEIN (HDL)
HDL carries cholesterol from the cells back to the liver to be later removed from our body system. HDL is also known as the ‘good cholesterol’.
Cholesterol levels can be affected by your lifestyle, age, family history, underlying medical conditions, or medication that you are taking.
Risk factors for high cholesterol include:
• Diet rich with saturated fat
• Physically inactive
• Smoking
• Excessive alcohol drinking
• Obesity
• Family history of elevated cholesterol
• Concurrent chronic conditions such as diabetes, high blood pressure
• Underlying medication conditions such as familial hypercholesterolemia, or thyroid disease may increase risk of developing high cholesterol.
You are advised to consider screening your cholesterol level, and discuss with doctor on both lifestyle and medication (if necessary) management for controlling the cholesterol level.
Healthy Switch
• Fat chunky meat lard, Ghee
• Butter
• Coconut oil / cream
• Full cream dairy (Milk / Cheese / Yoghurt)
• Cake / Pastries / Pudding
• Biscuits / Confectionary
• Rice / Pasta / Bread / Flour / Cereals
Aim for This
• Good oily fish (Salmon, mackerel, halibut, sardines, etc)
• Seeds oils / Olive oil
• Avocado
• High fibre vegetables
• Nuts
• Full grains / wholemeal / oats / beans / peas
If your cholesterol levels are persistently high, you are at risk of developing:
1. Atherosclerosis
As the arteries or blood vessels are build up with excessive cholesterol plaques, the arteries will narrow.
2. Angina
If the narrowing of arteries occurs in the heart, one may experience a heavy, dull, chest tightness over the center of the chest, spreading to the lef side of the arm, neck, jaw or even the back. This is known as angina. The symptoms of angina are due to reduced blood flow to the heart muscle especially when you are under physical exertion.
3. Heart attack/ Myocardial infarction
When the blood supply to the heart is completely cut off/ blocked by cholesterol plaques or even a blood clot, a person can develop a heart attack. This is a medical emergency and you can succumb to the condition if no immediate medical attention is given.
4. Coronary heart disease
Patients can be asymptomatic even with evidence of blockages of the main arteries of the heart. Without appropriate health intervention, these patients are at higher risk to develop angina or heart attack.
5. Stroke
If the blood supply to the brain is completely blocked by the cholesterol plaques, a stroke can occur. This is a serious medical emergency. The outcome of a stroke event ranges from full recovery, mild disability, bedridden, inability to talk/ move or even death.
6. Transient ischemic attack (TIA) or mini stroke
This is due to temporary interruption or blockage of blood flow to the brain due to cholesterol plaques.
7. Peripheral vascular disease
If the blood vessels flow is reduced or blocked by cholesterol plaques, a personal can develop peripheral vascular disease. Symptoms of peripheral vascular disease include changes of skin colors, weak pulses on the limbs, hair loss, or even gangrene.
Your doctor may advise you on lowering your cholesterol level to reduce the risks of cardiovascular conditions.
Indications to lower your cholesterol levels include:
Do discuss with your doctor on ways to manage the cholesterol levels, if required, your doctor may discuss on medication options to lower the cholesterol levels.
If you have increased risk of heart disease, diabetic, family history of high cholesterol or other cardiovascular conditions, your doctor may advise you to consider a medication called statin to lower the cholesterol level on top of lifestyle measures of exercise and healthy eating.
Your doctor will discuss with you on the target levels of your cholesterol depending on the cause of your high cholesterol levels, your age, and other risk factors that you may have.
Contrary to concerns of negative side effect of statin, most patients who are on statin tolerated well and uneventfully. Common side effects include, muscle aches and possible abnormal liver blood tests.
However, it is worth noting that your doctor will start and titrate your cholesterol for the lowest possible effective dose to control your cholesterol. You will be monitored with follow up blood tests after starting consuming statin. If there are abnormal results to suggest side effect from statin, your doctor may advise you to lower or stop the dose.
Side effects usually resolve with withdrawal of medication. The decision of starting statin involves a weigh-up of both risks of pill burden and long term benefits of cardiovascular disease prevention. You can discuss with your doctor during your consultation on cholesterol levels.
A major component of health screening involves cancer screening.
Health screening allows screening for potential health conditions
Obstructive sleep apnoea, also known as OSA, is a condition characterised by repetitive upper airway obstruction during sleep, resulting in repeated blockage to breathing during sleep.
Thyroid disease is an umbrella term for disorders of the thyroid gland, leading to over production or under production of the thyroid hormones.
Asthma is a chronic respiratory inflammatory condition that is associated with coughing, wheezing, breathlessness and chest tightness.
Also known as high blood pressure, hypertension is a health condition whereby the blood pressure is pumped around your body at high pressure.
Diabetes refers to a metabolic disease that causes high blood sugar.
Obesity is defined as having an excess amount of fat in your system.
A good control of chronic diseases improves a person’s quality of life tremendously. Chronic diseases when left unattended, can lead to debilitating health conditions.
The immune system is your body’s natural defense mechanism and works to combat foreign pathogens.
General health screening is recommended for individuals of all ages, but the frequency and type of screening may vary depending on age, gender, and medical history.
