《Why You Should Lose Weight》
(Before Your Doctor Does It for You)

Let’s face it — losing weight is on everyone’s to-do list, somewhere between “learn a new language” and “finally organize my closet.”

Yet for most of us, it’s the one goal that gets postponed until our jeans stage a mutiny or the bathroom scale starts sighing audibly.

As a doctor, I’ve seen every excuse in the book. One patient told me, “Doc, I can’t jog. I have a sweet tooth.” I asked him to show me which part of his anatomy that was — he pointed to his mouth. Another proudly said, “I only eat once a day!” I was impressed until he added, “From 8 a.m. to midnight.”

The truth is, carrying excess weight isn’t just about vanity — it’s about vital organs trying to survive under duress. Your knees, for example, are the unsung heroes of your body. Each extra kilogram is like asking them to carry a backpack of bricks up a hill — every day. No wonder they creak louder than your old door hinge.

Your heart, meanwhile, works overtime like a factory worker on double shift, and your pancreas can’t take another complaint letter.

And then there’s sleep apnea — the nightly performance where you stop breathing long enough to scare your spouse into writing your eulogy. Or fatty liver, where your liver turns into a foie gras factory without your consent.

Worse still, being overweight or obese is strongly linked to an increased risk of many cancers. In fact, after smoking, obesity is now the second leading preventable cause of cancer worldwide.

The obesity cancer link is acting via hormonal effects, chronic inflammation, disrupted cell growth regulation, and the fat-linked cancer list is: breast (postmenopausal), endometrium (uterus lining) colon and re**um, esophagus (adenocarcinoma), kidney, liver, gallbladder, pancreas, thyroid, multiple myeloma, meningioma (brain lining), ovaries and stomach etc.

The good news is even modest weight loss (5–10%) can lower hormone levels and inflammation, reducing cancer risk significantly.

Regular physical activity, balanced diet, and maintaining a healthy BMI (18.5–24.9) are powerful preventive steps — more effective than many supplements combined.

But don’t despair. Weight loss doesn’t require living on kangkong or running marathons. Start small: climb stairs, skip sugary drinks, and don’t eat like you’re fueling for hibernation.

One of my patients lost five kilos simply by deciding that “second helpings” were for people at weddings, not weeknight dinners.

And remember — your goal isn’t to look like a celebrity. It’s to feel good enough that your own body doesn’t file a formal protest. The best reward? Waking up lighter, walking easier, and hearing your doctor say, “Whatever you’re doing — keep it up.”

So, lose weight not for the mirror, but for the marvelous machinery that keeps you alive. Besides, nothing feels better than being able to tie your own shoelaces without holding your breath.

“It’s All in Your Head!”

Every doctor has met that patient.
You know, the one who shows up every other week with a new complaint: chest pain on Monday, stomach cramps on Wednesday, and dizziness by Friday. You order blood tests, scans, ECGs—the full medical orchestra—and everything comes back beautifully normal. The patient stares at you, disappointed. “Doctor, are you sure? Because my pain feels very real.”

And they’re right. It is real.
It’s just that their body is playing the mind’s greatest hits album—Psychosomatic Symphony in A Minor.

[When the Mind Writes the Body’s Script]

“Psychosomatic” sounds fancy, but it simply means that the mind (psyche) and the body (soma) are gossiping behind your back. Whatever the mind feels too shy to say aloud, the body blurts out—usually through headaches, chest tightness, or mysterious stomach pains.

Take my friend Hussain, for example. Every time his boss sends an email titled “URGENT,” his eye starts twitching like it’s Morse-coding for help. During performance review season, both eyes join in. When he finally took a week off, the twitch vanished faster than his motivation to return to work. No medicine required—just a break from his stress factory.

That’s psychosomatic: real symptoms, wrong culprit.

[Stress—the Original Drama Queen]

Our ancestors used the stress response to run from tigers. Today, we use it to read group chats from our boss. The body doesn’t know the difference. It releases adrenaline and cortisol, the “fight-or-flight” hormones, which raise blood pressure, tighten muscles, and make you feel like you’ve swallowed a small espresso machine.

Over time, chronic stress turns the body into a walking alarm bell. One of my patients, a teacher, complained of a “knife stabbing” in her stomach every Sunday night. We did all the tests—ultrasound, endoscopy, you name it. All normal. When I asked what happens on Monday morning, she sighed: “Staff meeting.” Diagnosis: .

[When Your Body Becomes a Drama Channel]

Sometimes the body’s imagination runs wild. I once met a man who fainted whenever his mother-in-law visited. True story. He blamed “low blood pressure,” but his vitals were perfect. Turns out his subconscious had developed an elegant self-defense mechanism: temporary shutdown. I suggested therapy—or, alternatively, shorter visits.

The mind and body are like an old married couple—they can’t stand each other sometimes, but they can’t live apart. When the mind gets stressed, the body protests. When the body hurts, the mind sulks. And when neither gets attention, both go on strike.

[The Cure: Listen Before You Medicate]

Treating psychosomatic symptoms isn’t about telling patients to “just relax.” That’s like telling someone drowning in emotions to “swim better.” The real trick is learning to listen. Sometimes, your body is saying what your mouth refuses to: “I’m exhausted,” “I’m afraid,” or “I need help.”

Simple changes—sleep, laughter, journaling, or even gardening—can calm the nervous system better than half the pharmacy shelf. My patient with Sunday stomach pain started meditating for ten minutes daily. After a month, her ulcer-free stomach survived three consecutive Mondays. A miracle? No—just mindfulness.

Even doctors are not immune. During one post graduate medical school exams, my medical intern's back pain was so bad he was convinced he had slipped a disc. Turned out it was anxiety disguised as orthopedics. Once exams ended, his “disc” healed faster than you can say “graduation party.”

[A Laughing Matter—Literally]

Laughter, it turns out, is medicine. When you laugh, your brain releases endorphins that neutralize stress hormones. So if you find yourself grinding teeth, clenching shoulders, or developing mysterious rashes before Zoom meetings—try watching a comedy instead of Googling “rash before presentation.”

Your body isn’t betraying you—it’s just trying to get your attention in the only language it knows: symptoms.

[In the End: The Body Doesn’t Lie]

Psychosomatic illness reminds us that the mind and body are two apps running on the same operating system. When one crashes, the other throws an error message. So next time your stomach aches before a date or your back hurts after an argument, don’t panic—just check your emotional Wi-Fi. You might simply need to reboot your mood.

After all, it’s not “all in your head.” It’s everywhere—especially if you keep ignoring it.

《Are We Eating Too Much? 》
It’s ironic, isn’t it? For most of human history, people worried about not having enough to eat. Like we used to ask our friends or family members "have you eaten yet?" among the Chinese immigrant communities in South East Asia stemming from the psychic of the Great Famine during the war in China.

Today, many of us are fighting the opposite problem — trying to stop. Our ancestors chased wild boar for dinner; we chase “exotic meals.” They stored fat to survive winters; we store it for no apparent reason, except perhaps more chronic diseases.

"Welcome to the Buffet Era"

Food has never been more available — or more tempting. The situation is getting out of hands during the festive seasons like Deepavali, Christmas, Hari Raya or New Year Day etc. Also from drive-thrus to Grab foods apps, it’s easier to eat than to think. We snack while driving, scrolling, or even dieting. I once saw a man jogging on treadmill with a burger in one hand — he said it was “carb-loading on the go.”

What’s happening isn’t just indulgence — it’s biology. Our brains are wired to crave high-calorie foods because, in ancient times, those were rare and valuable. But now, sugar and fat are everywhere — and our survival instinct is turning against us. Modern foods are scientifically engineered to hit the “bliss point” — that perfect combo of sugar, fat, and salt that lights up the brain’s dopamine reward system.

In medical terms, it’s the same pleasure circuit triggered by addictive substances. The result? You don’t eat just one chip. You finish the bag, then look for dessert.

"Calories and Confusion"

Here’s a quick medical reality check: the average adult needs around 2,000 calories a day — yet many of us easily consume 2,500–3,000, often without realizing it.

That extra 500 calories a day can add up to about 2 kg of weight gain per month — or 24 kg a year. It’s no wonder obesity rates have tripled globally since 1975. In Malaysia, more than half of adults are overweight or obese, and 1 in 5 already has diabetes or prediabetes.

Our waistlines are expanding faster than our awareness.

"Eating Beyond Hunger"

The real problem isn’t just what we eat — it’s why. We no longer eat because our bodies need fuel; we eat for emotional reasons.
Stress? Snack.
Boredom? Snack.
Celebration? Definitely snack.

One of my patients once said she eats “to keep her mouth busy so she doesn’t argue with her husband.” Another confessed that midnight snacks “help him sleep better.” (They don’t — physiologically, late-night eating increases insulin spikes and disturbs melatonin, the sleep hormone.)

Emotional eating creates a vicious cycle — stress triggers hunger hormones like ghrelin, we eat to feel better, insulin rises, then we crash, and crave again. The body mistakes emotional need for physical hunger.

"Diseases of Excess"

Doctors now call it the “diseases of affluence” — conditions that arise not from scarcity but from over abundance. The list is long:

- Obesity increases the risk of heart attack, stroke, and certain cancers.
- Excess sugar leads to insulin resistance and type 2 diabetes.
- High salt raises blood pressure, which silently damages the heart and kidneys.
- Too much saturated fat clogs arteries, leading to coronary artery disease.

Even the liver, once thought to suffer only from alcohol, now faces Non-Alcoholic Fatty Liver Disease (NAFLD) — a result of sugary drinks and overeating. It’s now one of the most common chronic liver conditions worldwide.

"The Environmental Cost"

Here’s the global irony: while some people are eating too much, others still have too little. Every year, the world wastes over one-third of all food produced, according to the UN Food and Agriculture Organization.

That’s 1.3 billion tons of food — enough to feed the entire hungry population several times over. And all that wasted food produces methane, a greenhouse gas 25 times more potent than carbon dioxide. In other words, overeating is warming the planet, too.

"How to Eat Less" (and Live More)

So how do we stop? Not through guilt or extreme diets — those usually backfire. The answer lies in mindful eating:

- Pause before eating. Ask, “Am I truly hungry or just seeking comfort?”
- Eat slowly. It takes about 20 minutes for the brain to register fullness.
- Stop at 80% full — the Japanese call this Hara Hachi Bu.
- Avoid eating late at night when metabolism slows.
- Choose real foods — vegetables, fruits, grains, lean protein — over ultra-processed products.

And if you must snack, choose nuts, yogurt, or fruit instead of chips or instant noodles. Your pancreas and heart will thank you later.

"The Joy of Enough"

Eating less doesn’t mean living less. It means rediscovering the simple pleasure of taste, gratitude, and conversation. My grandmother used to say, “Eat what you love — just not all of it at once.” She lived to 99, proof that moderation works better than medicine.

Food is one of life’s greatest joys, but it’s meant to nourish, not numb. We need to eat to live — not live to eat.

"Final Bite"

So, are we eating too much? Absolutely — but the good news is, we can laugh while we fix it. Next time you reach for that extra slice of cake, ask yourself: “Do I need this, or am I just emotionally attached to frosting?”

And if the answer is yes — fine, enjoy it. Just balance it tomorrow with a walk, a salad, and maybe a little less sugar in your coffee. Because in the end, health isn’t about giving up everything — it’s about knowing when to stop.

*社交媒体成瘾：无尽滑动的陷阱*

你是否有过这样的经历——原本只想“刷五分钟手机”，结果一抬头，一个小时悄然溜走。咖啡凉了，脖子酸了，你不禁纳闷：时间都去哪儿了？

社交媒体的确有趣。它带来可爱的宠物视频、即时的新闻资讯、与旧友重逢的惊喜。但当“五分钟”每天演变成数小时，这已不仅仅是小小的习惯，而可能成为健康隐患。

医生们越来越多地把“社交媒体成瘾”视为一种真实存在的健康问题——它伤害的不只是大脑，还包括身体和人际关系。

《大脑与社交媒体》

每一次“点赞”或消息提醒，都会让大脑释放多巴胺——这正是我们吃巧克力、赢游戏时的快感来源。

问题在于：快感转瞬即逝，大脑便渴望再次刺激。于是，青少年因为发的贴文没有被点赞而焦虑；成年人则在会议或聚会时偷偷刷手机，甚至正在開車時也機不離手。这不是意志薄弱，而是生理机制：大脑已被重新“布线”，渴望持续的反馈循环。

医学表现：焦虑障碍、FOMO（害怕错过）、强迫性刷屏。

《“偷走”睡眠的蓝光》

身体需要休息，就像手机需要充电。但在床上滑手机会让大脑保持“白天模式”。屏幕蓝光会抑制褪黑素的分泌——这种激素正是催促我们入睡的“信号”。

结果呢？入睡困难、浅眠、第二天早晨易怒疲惫。长期下来，还会损害记忆、专注力，甚至提高高血压、胃炎、免疫力下降的风险。医生称之为“睡眠卫生不良”。

《从“低头族”到“滑屏拇指”》

长时间沉迷手机，对身体的伤害同样明显：

低头颈：长时间低头，颈肩僵硬疼痛。
腕管综合征 & 滑屏拇指：反复点击，手腕和手指酸痛。
数码眼疲劳：眼干、视物模糊、头痛。
久坐少动更会加重问题：体重增加、姿势不良、糖尿病和心脏病风险上升。

《情绪的过山车》

社交媒体展示的多是“高光时刻”——旅行、豪车、精修自拍。长久浸泡其中，平凡生活显得无趣。这种“社会比较陷阱”已被证实会引发焦虑与自卑。

更严重的是网络霸凌。一个恶意评论往往比上百个赞更刺痛人心。医生发现，越来越多青少年因网络欺凌而出现抑郁与压力症状。

《数字时代的人际疏离》

讽刺的是，社交媒体原本是为了“连接”，却常让我们更加疏远。夫妻为吃饭时刷手机争吵；一家人坐在一起，却各自沉迷于屏幕；朋友间的交流简化为几个表情符号。

这种现象甚至有个名字：低头族冷落（phubbing）。日积月累，这些小小的“忽视”会慢慢消磨掉人际的温度。

《为什么医生在意？》

与烟酒不同，社交媒体成瘾没有宿醉，没有过量警报。伤害往往悄悄积累：失眠、酸痛、焦虑、关系紧张。

虽然目前尚未被《精神障碍诊断与统计手册》（DSM-5）正式列为独立疾病，但它与“网络游戏障碍”十分相似。批评者担心“病理化”正常行为，但越来越多的研究表明：社交媒体成瘾确实造成身心损害，值得纳入预防与治疗体系。

《如何摆脱》（不用变隐士）

别担心，解决办法并不是删光所有App、与世隔绝。关键在于平衡。以下几个方法简单有效：

1. 数字宵禁：睡前至少一小时关闭所有设备。
2. 应用定时：利用手机自带功能限制使用时间。
3. 无手机用餐：让餐桌回归交流，而不是蓝光。
4. 用兴趣替代刷屏：阅读、运动、园艺、拼图。
5. 定期数字断食：尝试每周抽一天不碰社交媒体。

开始时或许不适应，但逐渐能帮大脑“重设”，养成更健康的习惯。

《结语：点赞与人生》

社交媒体本身并非洪水猛兽。它让我们获取知识、收获快乐、与世界紧密相连。但正如糖分和快餐——过量则伤身。

关键在于平衡。让社交媒体成为工具，而不是陷阱。下次你点开那个闪烁的图标时，不妨停一秒，问自己：我是为了快乐打开，还是仅仅为了满足大脑的渴求？

慎重选择，或许就能换来更好的睡眠、更平静的心态、更健康的关系，以及更多属于现实世界的时间。

‘’Social Media Addiction: Scrolling Into Trouble‘’

We’ve all been there—opening a social media app for “just five minutes,” and suddenly an hour has vanished. The coffee is cold, your neck aches, and you’re wondering where the time went.

Social media is fun, no doubt. It gives us dog videos, instant news, and a chance to reconnect with old friends. But when those five minutes turn into hours every day, it’s more than just a harmless habit.

Doctors are starting to recognize “social media addiction” as a genuine health issue that affects the mind, body, and even relationships.

《The Brain on Social Media》

Every “like” or notification delivers a hit of dopamine, the brain’s reward chemical. It’s the same system triggered when we eat chocolate or win a game. That little burst of pleasure keeps us coming back for more.

But here’s the catch: the high fades quickly, so our brain demands another hit. Before long, checking your phone isn’t just funit feels necessary.

That’s why teenagers and even adults alike, panic or become anxious, when their post gets no likes, or why adults sneak a peek at Facebook in the middle of meetings or during friends gathering. This isn’t weakness; it’s biology. Our brains have been wired to crave the constant feedback loop that social media provides.

Medically, this manifests as: Anxiety Disorders – fear of missing out (FOMO) and compulsive scrolling.

《Sleep Thieves and Blue Light》

Our bodies need rest like phones need charging. But scrolling in bed keeps your brain on “day mode.” The blue light from screens blocks melatonin, the hormone that tells your body it’s time to sleep. Instead of drifting into dreamland, your brain stays alert, tricked into thinking it’s still daylight.

The result? Trouble falling asleep, shallow rest, moody and groggy mornings. Doctors call this “poor sleep hygiene.” Over time, it adds up—affecting memory, focus, hypertension, gastritis, even immune function.

《From Neck Pain to “Text Thumb”》

Social media addiction also creeps into our physical health. Hours hunched over screens bring problems such as:

Text neck pain and stiffness from tilting the head downward.

Carpal tunnel syndrome and text thumb – sore wrists and aching fingers from endless tapping.

Digital eye strain – dryness, blurred vision, and headaches.

Add in long sitting hours, and you’ve got another issue: less physical activity. That means weight gain, poor posture, and increased risk for conditions like diabetes and heart disease.

《The Emotional Roller Coaster》

Social media is a stage where people post their best moments—vacations, new cars, glowing selfies. Constant exposure to these “highlight reels” can make normal life feel dull. This social comparison trap is a proven trigger for anxiety and low self-esteem.

And then there’s cyberbullying, which leaves lasting scars, especially on young people. A single cruel comment can echo louder than a hundred compliments. Doctors are seeing more teens with stress and depression directly linked to online harassment.

《Relationships in the Digital Age》

Ironically, while social media is meant to connect us, it often drives us apart. Couples argue when one partner is glued to the screen during dinner. Families sit together, but everyone is lost in their own feed. Friends reduce conversations to emojis instead of real talks.

This phenomenon even has a name: phubbing—snubbing someone by focusing on your phone. Over time, these small moments of disconnection can erode the warmth of relationships.

《Why Doctors Care?》

Unlike smoking or alcohol, social media addiction doesn’t come with obvious warning signs. There’s no hangover, no overdose. The harm builds quietly: sleepless nights, aching joints, anxious minds, and strained relationships.

In addition, social media addiction lacks formal recognition in diagnostic manuals such as the DSM-5, though it is closely related to “Internet Gaming Disorder.” Critics argue that labeling it as an addiction medicalizes normal behavior. However, increasing evidence of its harmful mental and physical consequences suggests that it deserves structured recognition, preventive strategies, and treatment protocols.

That’s why medical experts are pushing for recognition of social media addiction as a genuine health issue. It may not involve a substance, but it rewires the brain and damages health just the same.

《How to Break Free 》
(Without Becoming a Hermit)

The good news is you don’t have to delete all your apps and live in the woods. Balance is possible.

Let me suggest a few simple but effective strategies:

1. Digital curfew – Power down all devices at least an hour before bedtime.

2. Set app timers – Many phones can track usage and remind you to log off.

3. Phone-free meals – Enjoy conversations without the glow of screens.

4. Replace scrolling with hobbies – Reading, sports, gardening, or even puzzles.

5. Plan digital detoxes – Try a 24-hour social media break once a week.

These steps may feel uncomfortable at first, but over time they help retrain the brain and restore healthier habits.

《Conclusion: Likes vs. Life》

Social media itself isn’t bad—it connects us, educates us, and sometimes even makes us laugh until we cry. But like sugar or fast food, too much can harm your health. The dangers are subtle but serious: poor sleep, aching bodies, anxious thoughts, and lonely hearts.

The secret is balance. Use social media as a tool, not a trap. The next time your finger hovers over that glowing icon, pause and ask yourself: Am I opening this app for joy—or just to feed my brain’s craving for another dopamine hit?

Choosing wisely could mean better sleep, calmer thoughts, healthier relationships, and more time for life beyond the screen.

"Let's Talk About Ghosts‘’
(in Hungry Ghosts Month)
Tonight at midnight, the grand gate in hell is supposed to open wide to release the hungry ghosts to wander about on Mother Earth. It is supposed to be a month-long holiday in a year for the captured ghosts.

During this month, some patients will avoid hospitalisation or surgery at all costs, unless it is necessary, for fear of ghostly unfavourable interference.

*A Doctor’s Perspective on Ghosts in Medical Practice*

When I first graduated from medical school, I thought my stethoscope and knowledge of physiology would explain every illness I encountered.

Now as a consultant physician, I was trained to interpret illness through the lenses of anatomy, physiology, and pathology. My textbooks never mentioned ghosts. Yet, in the real world of clinical practice, I have encountered them—not as supernatural beings, but as powerful beliefs that shape the way patients understand their suffering.

In my years of practice, I have come to realise that “ghosts” appear in clinics and hospital wards more often than we might expect— as beliefs, experiences, and memories that profoundly affect our patients.

*Meeting Ghosts Through Patients*

I remember a patient who came to the emergency department with chest tightness, sweating and shortness of breath. His whole chest was covered with talisman and prayer paraphernalia. Medically, his symptoms pointed toward panic attacks linked to stress. But he was convinced that a ghost had pressed on his chest while he slept.

Another patient, a widow, told me she often saw her late husband at the foot of her bed. She feared others would think she was “mad,” but for her, the vision was a source of comfort during grief.

I also remember, one evening, I was called to see an elderly man who refused to sleep in his ICU hospital bed. He whispered that the bed was haunted, that he could see a figure standing in the corner and kept pushing him off his bed. Medically, I suspected delirium due to infection. But to him, the ghost was real. Simply telling him “it isn’t true” would not have helped. I listened, reassured him, and arranged for treatment of his infection. The next day, the ghost had vanished along with his fever. That night taught me that addressing patients’ ghostly fears with respect is as important as prescribing antibiotics.

For doctors, these are not trivial stories. They are windows into the patient’s worldview, shaping how they seek help and how they respond to treatment.

*The Balancing Act*

The challenge lies in balance. To dismiss ghost beliefs as superstition risks alienating the patient. To embrace them uncritically may neglect serious medical conditions. Our task is to listen with respect, explore the meaning behind the experience, and gently guide patients toward safe, effective care. Sometimes this means explaining phenomena like sleep paralysis in plain terms. At other times, it means acknowledging the spiritual dimensions of loss and grief.

*Ghosts in the Doctor’s Own Life*

It would be untrue to say that ghosts belong only to patients. Doctors, too, are haunted. We carry the ghosts of patients we could not save, of errors we wish we had avoided, of cases that linger in memory long after the ward is quiet. These ghosts are not frightening apparitions but emotional imprints—reminders of our own vulnerability and humanity.

*Conclusion*

From a doctor’s perspective, ghosts in medical practice are less about the supernatural and more about meaning.

They are cultural, psychological, and emotional realities that cannot be ignored.

Sometimes they are hallucinations from illness; sometimes they are grief taking form; sometimes they are cultural beliefs that guide how people explain suffering. Whether real or symbolic, they are part of the patient’s reality—and to ignore them is to ignore part of the person.

They remind us that medicine is not only about curing disease but also about understanding the whole person—their fears, their beliefs, their grief, and their hopes. And in this way, ghosts, too, become part of the healing journey.

In medicine, we often say our duty is to cure sometimes, to relieve often, and to comfort always. Ghosts remind us of that last responsibility. By listening without judgment, by respecting what our patients see and feel, we honour not just their health, but their humanity.
