Dr Choong Khhai Munn Hi, I’m Dr Choong! I’m a family doctor in Damai Perdana, Cheras. I help people with common illnesses, long term health problems.

Dengue cases and deaths are rising in Selangor and many patients didn’t even know they had it early on.

Fever is not always “just viral.” If you or someone around you has a sudden fever, especially in a dengue hotspot, it’s important to think about dengue from day 1.

Early testing, proper monitoring, and knowing the warning signs can make a huge difference.

Don’t ignore symptoms. Don’t delay testing. And avoid the wrong medications if dengue is suspected.

Eating eggs every day… is it actually bad for your heart?

This is something I get asked a lot in clinic, and the answer isn’t as scary as people think.

For most healthy individuals, eating eggs in moderation is generally safe, and they’re actually a really good source of protein and nutrients.

The concern has always been cholesterol, but what we now understand is that overall diet and lifestyle play a much bigger role than just one food.

There have been multiple studies over the years showing that moderate egg consumption does not significantly increase the risk of heart disease in generally healthy people.

That said, context matters. If your diet is already high in processed foods, fried foods, or processed meats, or if you have existing heart disease, then you do want to be more mindful. There’s no one-size-fits-all rule here.

Also, how you cook your eggs makes a difference.
Simple takeaway: Most healthy adults can safely have about 1 to 2 eggs per day.

Focus on your overall diet, not just eggs. Save this if you’ve been confused about eggs, and share it with someone who still avoids telur.

Vitamin C is one of the most popular remedies people reach for when they feel a cold coming on.

But does it actually work?

Current evidence shows that vitamin C does not prevent most people from getting a cold. So taking it daily will not act as a shield against infection.

However, if you take vitamin C regularly, it may help shorten the duration of a cold slightly. The effect is modest.

Starting vitamin C only after symptoms begin does not seem to consistently reduce how severe the cold is or how long it lasts.

Also remember that more is not always better. The upper limit for vitamin C is 2000 mg per day. Taking too much can lead to side effects like stomach upset and diarrhea.

So yes, vitamin C has a role, but it is not a cure or a quick fix. Focus on good sleep, hydration, and overall health habits as your main defense.

Save this for the next time you feel a cold coming on!☺️

Vaccines aren’t just for kids, they’re a key part of aging well.

As we get older, our immune system weakens, and infections like influenza, pneumonia, dengue, and shingles can hit harder, lead to complications, or even require hospitalisation.

The good news is, many of these are preventable.
If you’re above 50, or caring for someone who is, it’s worth taking a moment to review vaccination status. A simple discussion with your neighbourhood GP can help you understand which vaccines are suitable based on your health and risk factors.

Prevention is always better than cure. It saves time, reduces healthcare costs, and most importantly, prevents unnecessary suffering down the road.

Vitamin C is important for immunity, skin health, and wound healing. But more does not always mean better.

In this reel, I explain how much you actually need based on age, the signs of deficiency, and why high dose supplementation is not always harmless.

Also a reminder, most people can meet their daily needs through food alone if they eat enough fruits and vegetables.

Can cranberry treat UTI?
Short answer no.

But there is a bit more to it. Cranberry does not treat an active urinary tract infection. If you already have symptoms, proper medical treatment is still necessary.

What cranberry can do is help with prevention. It contains compounds called proanthocyanidins that may reduce the ability of bacteria to stick to the urinary tract, lowering the risk of recurrent infections.

So for treatment No, but for prevention Yes.

It can be a helpful option, especially for those who get frequent UTIs, and it is easily available over the counter. But if symptoms are already present, do not delay seeking medical attention.

Save this for future reference and share it with someone who always reaches for cranberry juice first.

Ever been told to take fish oil to lower your cholesterol?

Here’s the truth. Fish oil is actually great at lowering triglycerides, which is a type of fat in your blood. But when it comes to LDL, the bad cholesterol that clogs your arteries, it doesn’t really help and can sometimes even increase it slightly.

So why do people still take it?

Because fish oil may reduce heart disease risk through other effects like lowering inflammation and helping prevent blood clots, not by lowering LDL.
That’s why it’s important to understand what your numbers actually mean instead of relying on supplements alone.

And just to be clear, fish oil is not a replacement for proper cholesterol treatment like statins.

If your goal is to lower bad cholesterol, you need the right approach, not just a popular supplement.

Save this so you don’t fall for the myth, and share it with someone who’s taking fish oil for the wrong reason.

Most people measure their blood pressure incorrectly, and it can lead to misleading readings.
If you want accurate results, preparation matters just as much as the device you use.

Before checking your BP, make sure you:
• Avoid smoking, caffeine, and exercise for at least 30 minutes
• Sit quietly and rest for 1 minute
• Keep your back and arm supported
• Place your feet flat on the floor (no crossing)
• Stay relaxed and avoid talking during the reading
Small details can significantly affect your blood pressure reading.

That’s why we don’t rely on a single measurement, we look at consistent readings over time, especially from home monitoring.

Save this for your next BP check, and share it with someone who monitors their blood pressure at home.

Most people think high blood pressure only leads to stroke.

But the truth is, it can quietly damage your heart, kidneys, eyes, brain, and blood vessels long before any symptoms appear.

That’s why hypertension is often called a silent condition. You can feel completely fine and still have ongoing damage inside your body.

The good news is, this is preventable. Regular blood pressure checks and proper control can significantly reduce these risks. Don’t wait for symptoms to show up. By then, it might already be complicated.

Take control early and protect your future health.

I’m sure many of you have heard that painkillers can damage the kidneys… but how true is this really?

The answer is: it depends on who is taking them.

Common painkillers like ibuprofen, diclofenac, and naproxen (NSAIDs) are generally safe for short term use in healthy individuals. But in certain groups, especially those with kidney disease, dehydration, or heart problems, they can quietly cause harm.

In this video, I break down:
• How NSAIDs affect kidney blood flow
• Why patients with CKD are more at risk
• The role of prostaglandins (your kidney’s “helper chemicals”)
• And why some people develop swelling or abnormal potassium levels

This is something I see quite often in clinic, especially in patients self-medicating long term for joint pain.

If you’re taking painkillers regularly, it’s always worth checking if it’s the right choice for you.

Not all painkillers are harmful
But the right one depends on your overall health.
