《疑病症——最怕漏掉真正的病》
《Hypochondria》
(The Danger of Missing a Real Disease)
行医四十年,我发现最难处理的病人,
不一定是患上罕见病的人。
有时候,反而是那个坚信自己什么病都有的人。
“医生,我觉得这次真的不对劲。”
可是....
验血:正常。
心电图:正常。
扫描:正常。
两个星期后,他又回来了:
“医生……你真的确定没有问题吗?”
这就是所谓的"健康焦虑" ("health anxiety"),
以前常叫“疑病症” (hypochondria)。
这类病人对身体特别敏感。
有人量血压一天50次,远比看 WhatsApp 还勤。
头痛两天,就开始怀疑脑生瘤。
心脏突然“扑通”一下,马上担心心脏病爆发。
颈部摸到一粒小淋巴结,已经准备马上预约三个专科医生。
现代人还有一位全天候、免预约的“医生”:
Dr Google。
Google 用来找餐厅,非常方便。
但拿来诊断疾病,就有一点可怕。
你输入“胃胀”,点几下之后,可能已经看到胃癌。
再点几下,可能连遗嘱葬礼都筹备及写好了。
所以医生经常劝病人:
少 Google 一点。
不过,事情还有另一面。
我们做医生的,也必须提醒自己:
疑病的人,有时候真的会生病。
假设一位病人过去已经因为胸痛来看过 15 次。
每次心电图正常。
验血正常。
检查也没有发现什么严重问题。
当第 16 次胸痛出现时,医生很自然会想:
“又来了。”
这三个字,其实有时候很危险。
因为第 16 次,不一定和前面 15 次一样。
一个长期焦虑的人,照样可能患上心脏病。
一个经常担心癌症的人,也不会因此得到“癌症免疫力”。因为焦虑并不是疫苗。
医学上真正危险的,是我们开始看“标签”,
而不是看“病人”。
如果医生已经在心里认定:
“这个病人就是疑病。”
那么新的疾病,就有可能被旧的印象掩盖掉。
胸痛?焦虑。
心悸?紧张。
胃痛?压力。
体重下降?想太多。
因此,每一次病人回来,
我们其实都应该重新问一个问题:
“这一次,有没有什么不同?”
症状是不是新的?
是不是越来越严重?
持续时间是不是更长?
性质有没有改变?
有没有发烧、气促、晕厥、出血、
明显体重下降等危险警讯?
体检有没有新的发现?
这些问题,往往比一句“你不要想太多”更重要。
当然,这并不是说什么都要检查。
如果每一次头痛都做 MRI,
每一次心悸都做 Angiogram/CT Scan,
每一次胃痛都做 PET scan,
那么医院以后恐怕不是病床不够,
而是扫描机不够。
真正好的医学判断,永远是在两个极端之间。
一边是:什么都查。
另一边是:什么都不查。
前者可能造成不必要的医疗费用、辐射、
假阳性结果,甚至更多焦虑。
后者则有可能漏掉真正的问题。
所以医生要做的,不是满足病人的每一个恐惧,而是判断:
这一次,值不值得进一步调查?
我也很喜欢提醒年轻医生一件事:
安心,也应该有“有效期限”。
不要只告诉病人:
“全部正常,不要担心。”
更好的说法是:
以"今天"的情况来看,检查是令人放心的。
不过,如果症状持续、越来越严重,
或者出现新的变化,请再回来。”
“今天”两个字,非常重要。
因为医学检查只代表当下。
检查是一张照片,疾病却是一部电影。
六个月前心脏检查正常,不代表今天新出现的胸痛一定没有问题。
两年前胃照镜正常,也不能永远替未来的胃痛作为担保。
当然,‘’健康焦虑‘’本身也是真实的问题。
如果一个人每天检查自己的身体几十次,不断量血压、摸淋巴结、检查心跳,上网查症状,今天看医生甲,明天看医生乙,后天再找医生丙确认——
久而久之,他的人生可能不是在“生活”,而是在“等疾病出现”。
这种情况,同样需要帮助。
有时真正需要治疗的,并不是身体,
而是对疾病‘’持续失控‘’的‘’恐惧‘’。
所以,从一位内科顾问医生的角度来说,
处理健康焦虑其实有两个原则:
病人不要因为每一个小症状,
就要求做全身扫描。
同时,
医生也不要因为病人以前经常担心,
就自动认为这一次还只是焦虑。
一个病人可以连续担心 27 次都没有大问题。
但没有任何医学定律规定:
第 28 次也一定没事。
所以医学上最值得警惕的一句话,也许不是:
“你患了严重疾病。”
而是:
“不用理他啦,他这个人本来就什么都担心。”
因为真正理想的医法,
不只是知道什么时候应该检查。
更重要的是——
知道什么时候,必须‘’重新细心和认真‘’再听一次。

《Hypochondria》
(The Danger of Missing a Real Disease)
《疑病症——最怕漏掉真正的病》
After 40 years in clinical practice, I have learned that some of the most difficult patients are not necessarily those with rare diseases.
Sometimes, they are the ones who are "convinced" that they have every disease.
“Doctor, I really think something is wrong this time.”
But....
Blood tests: normal.
ECG: normal.
Scan: normal.
Two weeks later, they are back.
“Doctor… are you absolutely sure?”
This is what we now call "health anxiety", traditionally known as "hypochondria".
These patients can be extremely alert to every little sensation in their body.
Some check their blood pressure 50x a day, more often than they check WhatsApp.
A headache for two days becomes a brain tumour.
One skipped heartbeat becomes an impending heart attack.
A tiny lymph node in the neck suddenly requires three specialists, several blood tests and possibly a family prayer meeting.
And modern patients have another "doctor" available 24 hours a day, seven days a week, with no appointment necessary: Dr Google.
Google is excellent for finding a nearby restaurant.
For medical diagnosis, however, it has a remarkable talent for turning simple bloating into "stomach cancer" within four clicks.
Another three more clicks and you may already be wondering when to start writing your will or planning your funeral..
That is why doctors often tell patients:
Google a little less.
But there is another side to this story.
As doctors, we also have to remind ourselves of one uncomfortable fact:
People with health anxiety can still become genuinely ill.
Imagine a patient who has already attended 15 times by GPs or Specialists for chest pain.
With ECGs normal.
Blood tests normal.
Previous investigations were also reassuring.
So when chest pain episode number 16 arrives, the doctor may naturally think:
“Here we go again.”
Those four words can sometimes be dangerous.
Because episode number 16 may not be the same as episodes 1 to 15.
A person who worries constantly can still develop heart disease.
Someone who has feared cancer for years does not develop "immunity" against cancer.
Because anxiety is not a vaccine.
One of the biggest dangers in medicine is when we start treating "the label" instead of treating the patient.
Chest pain? Anxiety.
Palpitations? Stress.
Stomach discomfort? Worry.
Weight loss? “You are thinking too much.”
Once the doctor has mentally labelled someone as “a hypochondriac”, there is a danger that a genuine new illness may be hidden behind the old reputation.
So whenever such a patient returns,
there is one important question worth asking:
“Is something different this time?”
Is the symptom new?
Is it getting worse?
Is it lasting longer?
Has its character changed?
Are there warning signs such as fever, breathlessness, fainting, bleeding or significant weight loss?
Is there anything new on physical examination?
These questions are often far more useful than simply saying:
“Don’t think so much.”
Of course, this does not mean we should investigate everything.
If every headache needed an MRI or CT Scan,
every palpitation needed an angiogram,
and every stomach ache required a PET scan,
hospitals then would soon need more scanners than beds.
Good medicine sits somewhere between two extremes.
At one end: Investigate everything.
At the other: Investigate nothing.
The first approach may lead to unnecessary costs, radiation exposure, false-positive findings and even more anxiety.
The second may cause us to miss a genuine disease.
So the doctor’s job is not to satisfy every fear.
It is to decide:
Does this particular episode deserve further investigation?
There is another principle I often remind younger doctors about:
"Reassurance should have an expiry date".
Instead of simply saying:
“Everything is normal. Stop worrying.”
It is better to say:
“Everything looks reassuring "today".
But if the symptom persists, worsens or changes, please come back.”
The word “today” matters.
Medical tests represent one moment in time.
A test is a photograph.
Disease is a movie.
A normal heart test six months ago does not automatically explain new chest pain today.
A normal gastroscopy two years ago cannot guarantee that every future stomach symptom is harmless.
At the same time, health anxiety "itself" is a genuine problem and sometimes needs treatment.
If someone spends the whole day checking blood pressure, feeling lymph nodes, counting heartbeats, Googling symptoms and visiting Doctor A today, Doctor B tomorrow and Doctor C the day after for the same complaint, life can slowly become "less about living" and more about "waiting for the next disease to appear".
Sometimes, the illness that needs treatment is not the body. It is the constant, uncontrollable fear of illness.
So from a consultant physician’s point of view, there are really two simple principles:
Patients should not demand a whole-body scan every time something twitches.
But doctors should not automatically dismiss a new symptom simply because the patient has worried many times before.
A patient may worry 27 times and turn out to be perfectly fine.
But there is no medical law stating that:
Number 28 must also be nothing.
Perhaps one of the most dangerous sentences in medicine is not:
“You have a serious disease.”
Or it may be:
“Ignore him. He worries about everything.”
Because a good medical practice does not only know when to investigate.
More importantly, a good doctor knows when it is time to "listen carefully" all over again.
