    Quitting smoking isn’t easy, but it helps to understand where you are right now. I usually explain it using the 6 Stages of Change Model:

    1. Precontemplation – Not thinking about quitting yet.
    2. Contemplation – Starting to think about quitting.
    3. Preparation – Actively planning to quit.
    4. Action – Actively working to quit
    5. Maintenance – Staying smoke-free.
    6. Relapse – A slip-up, but a chance to learn and try again.

     

    From what you’ve shared, it sounds like you’re probably at stage 2 (contemplation) or maybe even stage 3 (preparation), which is fantastic. Thinking about quitting or getting ready to take action is such an important step, and you should be proud of that.

    Let me explain how nicotine replacement therapy (NRT) works in a simple way. When you smoke, you’re not just getting nicotine – you’re also inhaling other harmful chemicals, like tar and carbon monoxide, which do most of the damage to your health. With NRT, you still get a small, controlled amount of nicotine, but without all those harmful toxins. It’s a safer way to manage withdrawal symptoms and cravings while you work on breaking the habit.

    What’s great about NRT is that it’s very flexible, and we can control the dose. For example, if you use a patch, you’ll start with a higher dose to manage the cravings and then gradually reduce it over time. The same goes for gum, lozenges, or inhalers – you use them when you need them and slowly cut back as your cravings get better. This gradual approach makes quitting much more manageable, especially compared to going cold turkey.

    There are also a few types of NRT:

    • Patches give you a steady dose of nicotine throughout the day.
    • Gum or lozenges are great for sudden cravings when they hit.
    • Inhalers are very popular because they replace not just the nicotine but also the hand-to-mouth habit that many smokers struggle to let go of.
    • Sprays (mouth or nasal) provide quick relief for intense cravings.

     

    From my experience with other patients, a lot of them find the inhaler most helpful because it mimics the act of smoking, which can be one of the hardest parts to give up.

    I know some patients also worry if an inhaler is like vaping. It’s actually very different. With NRT inhalers, you’re only getting a controlled dose of nicotine – there’s no harmful chemicals, no burning, and no smoke. It’s purely a tool to help you quit, not something designed to replace one addiction with another.

    In Malaysia, you can get NRT products like patches, gum, and inhalers at pharmacies such as Guardian, Watsons, or Caring Pharmacy. Just ask the pharmacist, and they’ll guide you on how to use them properly. You can also visit a smoking cessation clinic or any general clinics if you’d like more support.

    The fact that you’re considering quitting is already a huge step. With the right tools and support, you can definitely do this.

    I’m sorry to hear you’ve been feeling this way. Experiencing a persistent headache and dizziness for over a week, especially after trying various medications, is not normal and should be properly addressed.

    I strongly recommend that you see a doctor as soon as possible to undergo a thorough examination and receive an accurate diagnosis. While over-the-counter medications like those for tension headaches or sinus congestion might help with common issues, they’re not designed to treat underlying or more complex causes of your symptoms. A doctor will be able to identify the root cause and create a treatment plan tailored specifically to your condition.

    It’s also important to note that taking multiple over-the-counter medications without medical guidance can carry risks. Every medicine has potential side effects, and some can interact with others in ways that may worsen symptoms or lead to other complications. It’s always safer to seek professional advice rather than continuing to self-treat.

    Your symptoms might also be linked to something like high blood pressure (hypertension) or low blood pressure (hypotension), which can both cause headaches and dizziness. A doctor will be able to check your vital signs and carry out further relevant tests to diagnose your condition.

    Please do see a doctor soon. Early intervention can make a big difference, and it’s the best way to ensure you get the right medications and start feeling better.

    Hi there. Good to know your father is recovering from his stroke. The first 6 months following stroke is the ‘golden time’ for neurological recovery. However we do still see improvements beyond 6 months. Twice per week rehabilitation may not be adequate for your father. I would advise a more comprehensive stroke rehabilitation program comprising of physiotherapy for physical strengthening, occupational therapy for hand function training and also retraining for activities of daily living and rehabilitation specialist assessment to assess if he is developing complications like spasticity and spasm.

    Yeah, I get it! Magnesium gets mentioned a lot when people talk about better sleep and for good reason. It actually plays a role in regulating melatonin, the hormone that tells your body when to sleep, and it also has a relaxing effect on your muscles and nervous system.

    Quite a number of people end up with low magnesium without even knowing, especially if they do not eat enough leafy greens, nuts, seeds, or whole grains. It is still best to check your magnesium level and kidney function before starting anything.

    But remember, Magnesium is not a miracle pill ok? It is just one of the many supplements out there that can help you sleep better, and sometimes there are other changes or supplements that might suit you more.

    Hi Lucian, thank you for your open sharing about your struggles with weight loss. I can certainly empathise with the challenges you’ve faced, as many of my patients have experienced similarly.

    As a gastroenterologist, I have experience with various weight loss interventions, including the use of gastric balloons like you asked. The gastric balloon is a deflated silicone balloon that is inserted into the stomach by swallowing grape size ball and then inflated inside the stomach. This takes up space in the stomach, which can help reduce appetite and promote feelings of fullness. In my practice, this balloon does not require surgery or endoscopy for insertion. After 4 months, the balloon will self-deflate and passes out naturally through the body.

    The gastric balloon can be an effective option for many patients who have had difficulties achieving their weight loss goals through lifestyle changes alone. Patients who undergo the gastric balloon procedure lose on average 10-15% of their total body weight over the 16 week period the balloon is in place. If needed, after thorough assessment by doctors, this balloon can be combined with other weight loss therapy such as medication for enhanced weight loss outcomes.

    The best weight management approach is highly personalised and depends on a variety of factors like your individual goals, overall health, lifestyle, personal preferences, and risk factors for obesity. There are a range of effective treatments available, and many people find success using a combination of different interventions over time.

    I would encourage you to have an open discussion with your doctors to review your full health history, understand your specific needs and objectives, and then recommend the right combination of interventions to help you achieve safe, sustainable weight loss. Feel free to reach out to me if you would like to learn more.

    It may be nothing or a throat infection.

    It is unusual for HIV seroconversion to occur at 2 weeks, and we never say never.

    Remember too that the 4th generation testing is better from day 21 onwards. You could have a false negative at your current day 14. For diagnosis at day 14, you may have to do a HIV proviral testing. This test is different from the regular HIV viral load PCR testing and maybe hard to find in your home country.

    Swollen lymph nodes, also known as lymphadenopathy, can vary in size, texture, and tenderness depending on the underlying cause. Here’s a detailed overview of what swollen lymph nodes feel like and what you might consider doing:
    Characteristics of Swollen Lymph Nodes

    1. Size and Shape: Swollen lymph nodes can range from small (a few millimeters) to large (several centimeters). They may feel like firm, round, or oval lumps under the skin. In some cases, they can be described as “rubbery” or “hard.”
    2. Location: Common areas for swollen lymph nodes include the neck, armpits, and groin. In your case, since you mentioned noticing bumps on your neck, these could potentially be lymph nodes.
    3. Tenderness and Pain: Swollen lymph nodes can be tender or painful to touch, especially if they are inflamed due to an infection. However, not all swollen lymph nodes are painful. If the bumps you feel are not tender or sensitive, they may not be inflamed, which could suggest a different underlying issue.
    4. Associated Symptoms: Swollen lymph nodes are often accompanied by other symptoms, depending on the cause. For example, if they are swollen due to an infection, you might experience fever, fatigue, or localized symptoms like a sore throat or cough. If there are no other symptoms, it may be less concerning.

    What You Can Do

    1. Monitor the Bumps: Keep an eye on the bumps. Note any changes in size, tenderness, or the appearance of new symptoms. If they remain stable and are not associated with other concerning symptoms, they may not require immediate action.
    2. Consult a Healthcare Professional: It is advisable to see a doctor if:
      • The bumps persist for more than a couple of weeks.
      • They increase in size or number.
      • You develop additional symptoms such as fever, night sweats, unexplained weight loss, or fatigue.
      • You have any concerns about the nature of the bumps.
    3. Medical Evaluation: During your visit, the doctor will likely perform a physical examination and may ask about your medical history and any associated symptoms. Depending on their findings, they might recommend tests such as blood tests, imaging studies (like ultrasound), or a biopsy to determine the cause of the swollen lymph nodes.
    4. Self-Care: While waiting for your appointment, you can manage any discomfort with over-the-counter pain relievers, such as acetaminophen or ibuprofen, if needed. Staying hydrated and maintaining a healthy diet can also support your immune system.

    Conclusion
    Swollen lymph nodes can be a normal response to infection or inflammation, but they can also indicate more serious conditions. Since you mentioned that the bumps are not painful or sensitive, they may not be a cause for immediate concern, but it is always best to consult a healthcare professional for a thorough evaluation to rule out any underlying issues.

    Experiencing night sweats and a slightly elevated temperature during sleep can be concerning, but it’s important to note that these symptoms can arise from a variety of causes, some of which are benign and others that may require further investigation. Here are some potential explanations and considerations:

    1. Environmental Factors: Sometimes, night sweats can be attributed to external factors such as a warm sleeping environment, heavy bedding, or wearing overly warm sleepwear. Ensuring a cooler room temperature and using breathable fabrics can help mitigate these issues.

    2. Lifestyle Factors: Consumption of spicy foods, caffeine, or alcohol before bed can lead to night sweats. Stress and anxiety can also trigger sweating during sleep. Evaluating your diet and stress levels may provide insights into potential triggers.

    3. Infections: Low-grade fevers and night sweats can be early signs of infections, such as viral illnesses or more chronic conditions like tuberculosis or HIV. If you have recently traveled or have been exposed to infectious diseases, it might be worth discussing this with a healthcare provider.

    4. Medications: Certain medications, including antidepressants, antipyretics, and some blood pressure medications, can cause night sweats as a side effect. Reviewing any medications or supplements you are taking with a healthcare provider can help identify if they might be contributing to your symptoms.

    5. Hormonal Changes: Although more common in women, hormonal imbalances can also affect men. Conditions such as hyperthyroidism can lead to increased sweating and a slightly elevated body temperature.

    6. Sleep Disorders: Conditions like obstructive sleep apnea can lead to night sweats. If you experience symptoms such as snoring, gasping for air during sleep, or excessive daytime sleepiness, a sleep study might be warranted.

    7. Idiopathic Hyperhidrosis: This is a condition where the body produces excessive sweat without an identifiable medical cause. While it can be bothersome, it is generally not harmful.

    8. Other Medical Conditions: Less commonly, night sweats can be associated with conditions like lymphoma or other malignancies, especially if accompanied by other symptoms such as unexplained weight loss or persistent fatigue.

    Given your symptoms, it would be prudent to monitor for any additional symptoms or changes in your condition. If the night sweats persist, worsen, or are accompanied by other concerning symptoms, it would be advisable to consult a healthcare provider. They can perform a thorough evaluation, which may include a detailed history, physical examination, and potentially some laboratory tests to rule out underlying conditions.

    The debate over the health implications of artificial sweeteners, also known as non-nutritive sweeteners (NNS), is multifaceted and continues to evolve as new research emerges. Here, we’ll explore the potential benefits and risks associated with their consumption, providing a comprehensive overview to aid healthcare professionals in advising patients.

    Potential Benefits

    1. Caloric Reduction: Artificial sweeteners provide sweetness without the calories, which can be beneficial for individuals looking to reduce their caloric intake. This can be particularly useful for patients with obesity or those trying to manage their weight.

    2. Glycemic Control: For individuals with diabetes, NNS can offer a way to enjoy sweet-tasting foods and beverages without affecting blood glucose levels. This can help in maintaining better glycemic control when used as part of a balanced diet.

    3. Dental Health: Unlike sugar, artificial sweeteners do not contribute to dental caries, making them a preferable option for oral health.

    Potential Risks

    1. Metabolic Effects: Some studies suggest that NNS may be associated with metabolic changes, such as alterations in glucose metabolism and insulin sensitivity. The mechanisms are not fully understood but may involve changes in gut microbiota or altered sweet taste receptor signaling.

    2. Weight Management: While NNS can reduce caloric intake, their impact on long-term weight management is unclear. Some research indicates that they may not lead to significant weight loss and could potentially contribute to weight gain by affecting appetite regulation and energy balance.

    3. Cardiovascular and Mortality Risks: Emerging evidence suggests a potential association between high consumption of artificially sweetened beverages and increased risks of cardiovascular disease and all-cause mortality. However, these findings are not yet conclusive and require further investigation.

    4. Gut Microbiome: There is growing interest in how NNS may affect the gut microbiome, potentially leading to dysbiosis. Changes in gut bacteria could influence metabolic health, although more research is needed to establish causality.

    Practical Considerations

    Patient-Specific Recommendations: When advising patients, consider individual health goals, dietary preferences, and any underlying health conditions. For some, the benefits of reducing sugar intake may outweigh potential risks associated with NNS.

    Moderation and Balance: Encourage patients to use NNS in moderation and as part of a balanced diet. Emphasize the importance of whole foods and non-sweetened beverages, such as water, as primary dietary components.

    Ongoing Research: Stay informed about the latest research findings, as the understanding of NNS and their health impacts continues to evolve. Encourage patients to be cautious and consult healthcare providers for personalized advice.

    Conclusion

    Artificial sweeteners present both opportunities and challenges in dietary management. While they offer a means to reduce sugar intake and manage caloric consumption, their long-term health effects remain a topic of active research. Healthcare professionals should guide patients based on current evidence, individual health profiles, and lifestyle considerations, while remaining open to new insights as the scientific community continues to explore this complex topic.

    The concept of the “best” food for weight loss is somewhat misleading, as weight management is more effectively approached through a balanced dietary pattern rather than sole reliance on specific foods. However, integrating certain types of foods into one’s diet can support weight loss due to their nutritional profiles and impacts on satiety and metabolism. Here are categories of foods often recommended for this purpose:

    1. High-Fiber Foods: Foods rich in fiber can promote feelings of fullness and reduce overall calorie intake. These include:
    – Whole grains: brown rice, oats, quinoa, barley.
    – Legumes: lentils, chickpeas, black beans.
    – Fruits: apples, pears, berries, bananas, citrus fruits.
    – Vegetables: broccoli, carrots, Brussels sprouts, spinach, kale.

    2. Lean Proteins: Adequate protein intake supports muscle maintenance and enhances satiety.
    – Poultry: skinless chicken and turkey.
    – Fish and seafood: salmon, sardines, tuna, shrimp.
    – Plant-based proteins: tofu, tempeh, edamame.
    – Eggs: a versatile and nutrient-dense option.
    – Low-fat dairy: Greek yogurt, cottage cheese.

    3. Healthy Fats: Fats can also contribute to satiety and provide essential nutrients, though they should be consumed in moderation.
    – Avocados: rich in monounsaturated fats.
    – Nuts and seeds: almonds, walnuts, chia seeds, flaxseeds.
    – Olive oil: preferred for cooking and dressing salads.

    4. Non-Starchy Vegetables: Low in calories but high in volume, these can fill the plate without adding excess calories.
    – Leafy greens: lettuce, arugula, Swiss chard.
    – Cruciferous vegetables: cauliflower, cabbage, bok choy.
    – Others: bell peppers, zucchini, asparagus.

    5. Calorie-Free Beverages: Hydration without added calories can help manage hunger cues.
    – Water: essential for all bodily functions.
    – Herbal teas and black coffee: provide flavor without calories.
    – Infused water: adds variety with natural flavors from fruits and herbs.

    Incorporating these foods into a broader plan that emphasizes portion control, balanced macronutrient distribution, and mindful eating practices will likely yield the most sustainable and healthy weight loss. Additionally, any dietary changes should be complemented by regular physical activity and adaptations to one’s lifestyle, such as stress management and sufficient sleep, to enhance the weight loss process and overall wellness.

    Before making significant dietary changes, it is advisable to consult with a healthcare provider or registered dietitian to tailor a plan that considers individual health conditions, nutritional needs, and weight loss goals.
