💓 Blood Pressure: The Silent Number You Shouldn’t Ignore! 💓

Did you know you can feel perfectly fine and still have high blood pressure? That’s why it’s called the “silent killer.”

🔍 What is blood pressure?
It’s the force of your blood pushing against your artery walls. We measure it as:
👉 Top number (systolic) = pressure when your heart beats
👉 Bottom number (diastolic) = pressure when your heart rests

📊 What’s normal?
✔️ Ideal: around 120/80
⚠️ High: 140/90 and above
🚨 Very high = increased risk of heart attack, stroke & kidney disease

💡 Common symptoms?
Most people have NONE… but sometimes:
• Headaches
• Dizziness
• Blurred vision
• Nosebleeds

🥗 What raises it?
• Stress 😓
• Too much salt 🧂
• Smoking 🚬
• Alcohol 🍷
• Lack of exercise 🛋️

💪 How to keep it healthy:
✔️ Move your body regularly
✔️ Eat more whole foods & less processed salt
✔️ Manage stress (sleep, breathe, reset)
✔️ Know your numbers – check regularly!

🩺 Quick tip:
Checking your blood pressure takes 2 minutes… but can save your life.

👉 Don’t wait for symptoms. Know your numbers.

Something interesting about GLP-1 injections.

I love the research that is coming to light regarding this medication. Other than weightloss it has heart protection and anti-inflammatory properties.

Excited to see in future what other benefits it has in store.

Clinical evidence has long suggested that the use of GLP-1 medications is linked to lower substance use. It’s also been speculated among patients taking the medications. Social drinkers, for example, contend that they no longer have the urge to order that glass of wine when they’re out with friends and smokers are finally able to stop.

Now a larger body of research shows what physicians and their patients have long noticed: Taking GLP-1 medications seems to significantly prevent and reduce addiction and substance use disorders. In a study published recently in The BMJ, researchers followed about 600,000 veterans with type 2 diabetes and found that GLP-1s prevented and treated substance use disorders when taken over a 3-year period. https://mdsc.pe/4t3I9ZV

☀️ SPF is more than just a number!☀️

Many people think SPF alone determines how well a sunscreen protects your skin — but there’s much more to look for on the bottle. In this video I explain the difference between UVA and UVB protection, what the SPF number really means, and how to choose a sunscreen that actually protects your skin properly.

Understanding these details can make a big difference in preventing sun damage, pigmentation and premature ageing.

I also briefly mention two excellent ranges that I trust and work with in practice: ISDIN and Lamelle. Both offer high-quality sunscreens with advanced protection and great skin compatibility.

✔️ Broad-spectrum protection
✔️ Daily use recommendations
✔️ What labels to check before buying

If you're unsure which sunscreen is best for your skin type, feel free to reach out — I stock and resell the ISDIN and Lamelle sunscreen ranges and can help guide you to the right option.

🎥 Watch the video to learn how to choose your SPF the right way.

I’m honoured to be speaking at the BASA Biokinetic Conference 2026 under the theme “Thrive.”

I’ll be discussing exercise considerations for patients with diabetes using injectable therapies, and how training strategies can support better glucose control and safer outcomes.

Excited to share practical insights with colleagues who are passionate about helping patients move, perform, and thrive. Looking forward to a great conference and meaningful discussions.

👀 Satisfying medical procedure alert!👀

This video shows the removal of an epidermal cyst, a very common benign skin lump that forms when keratin gets trapped under the skin.

Although harmless, these cysts can:
• Slowly grow
• Become inflamed or infected
• Be cosmetically bothersome

A small in-office procedure under local anaesthetic can remove the cyst completely.

If you’ve noticed a persistent lump under the skin, it may be worth getting it checked.

🦠 Viral Warts – What You Need to Know🦠

Viral warts are common skin growths caused by the human papillomavirus (HPV). They are harmless, but can be unsightly, uncomfortable, or spread easily – especially in children and active adults.

👣 Common types of warts:

• Common warts – usually on hands and fingers
• Plantar warts – on the soles of the feet (often painful)
• Flat warts – small, smooth warts often on the face or legs
• Periungual warts – around nails

🤝 How do you get warts?

Warts spread through direct skin contact or contact with contaminated surfaces (like pools, gyms, or shared towels). Small breaks in the skin make infection easier.

🩺 Treatment Available at Our GP Practice

While some warts may resolve on their own, many persist or spread without treatment.

At our practice, we offer:
✔️ Clinical assessment
✔️ Medical-grade topical treatments
✔️ Cryotherapy (freezing of warts) where appropriate
✔️ Advice on preventing spread and recurrence

Treatment is safe, effective, and tailored to both children and adults.

❗ When should you see a doctor?

• If warts are painful, bleeding, or spreading
• If home treatments are not working
• If warts affect face, feet, or nails
• If you are diabetic or immunocompromised

📍 31 Danie Joubert Street, White River
📞 013 170 5789/060 801 7462

Early treatment helps prevent spreading and discomfort.
