"Go for a comprehensive inspection... The inspection you did a few days ago, you don't need to do it today, save some money..."

Lin Feng said,

The patient Zhang Suhua quickly thanked him.

Lin Feng prescribed blood test, urine test, etc...

The patient took the checklist and went to do various checks.

...

after an hour,

The result of the check is out.

"what……"

Lin Feng took the "blood routine" and immediately saw the problem.

·Hemoglobin is only 58g/L (reference value 120-150)

This is severe anemia!

Above 90 is considered mild anemia, 60-90 is moderate anemia, and below 60 is severe anemia. The patient Zhang Suhua has severe anemia!

Lin Feng couldn't help guessing:

Such severe anemia is very likely to cause dizziness.

If the blood supply is not enough for the brain to use, then the brain function is bound to be impaired, such as dizziness, nausea, etc., and even short-term coma in severe cases.

This is a very reasonable inference.

Looking at the patient's face, it was indeed a little pale. At first, Lin Feng thought it was caused by dizziness and vomiting, but now it is estimated that it was caused by excessive blood loss.

So here comes the problem.

Why is there anemia?

Is blood lost for a short time or for a long time?

As I said before,

The cause of anemia is nothing more than: less blood production and more blood loss!

Then, Lin Feng asked: did he vomit blood, the aunt’s bleeding was normal and abnormal, the stool was black and not black, any history of disease (hemolytic anemia), whether there was hemorrhoids...

Asked a bunch of...

(I have already written it before, so I won’t write it in detail)

In the end, nothing special was discovered.

At this moment,

The son of the patient Zhang Suhua suddenly said:

"Doctor, does anemia have something to do with fava bean disease? My uncle seems to have fava bean disease..."

".................."

Lin Feng's face was solemn.

A little angry.

"What's the matter with you? Why don't you tell me if you have such an important medical history!!"

Fava bean disease is hemolytic, red blood cells will be destroyed, and will naturally become severely anemia.

"Hemolysis": Red blood cells rupture and hemoglobin escapes, which is called red blood cell lysis, or hemolysis for short. It can be caused by a variety of physical and chemical factors and toxins (causes: cold, acid-base, toxicity, hypotonic solution, strong mechanical shock).

There is also a type of "fava bean disease", which is also hemolytic anemia.

Fava bean disease is a type of glucose-6-phosphate dehydrogenase deficiency. In patients lacking this enzyme, red blood cells are very unstable. It is manifested as hemolytic anemia after eating fava beans, but the specific mechanism of hemolysis is unknown (not researched).

correct,

Broad bean disease is a genetic disease.

So if the patient's brother also has fava bean disease, Zhang Suhua is also very likely to have fava bean disease.

Lin Feng looked at the patient seriously: "Have you eaten broad beans recently ¨々?"

Zhang Suhua shook his head repeatedly: "I haven't eaten...

Lin Feng asked: "It's like fans, Doubanjiang..."

These may have broad bean ingredients.

Zhang Suhua nodded this time: "Yes, Doubanjiang...but I have no problem eating it before... and this time I only ate two spoonfuls..."

Lin Feng had a headache and explained: "Fava bean disease" does not cause hemolytic anemia every time you eat broad beans! Moreover, the degree of hemolysis and anemia of the affected person does not have a parallel relationship with the amount of fava beans eaten... I will give you an order, and you will have a check to see if there is "fava bean disease"..."

However, before the test, the blood must be refilled.

First, the patient was transfused with 2 units of red blood cells to relieve the anemia first.

After the blood transfusion,

The patient took a few checklists and went for a checkup.

...

The next patient,

"what……"

Lin Feng looked at the patient's face, pale.

Thinking of the last patient Zhang Suhua, I subconsciously felt that-anemia.

·Patient, Yu Xianwei, male, 35 years old...

As soon as I approach, sit down,

Lin Feng asked with a taste.

Mothballs.

"What's your question?"

"Dr. Lin, this is the case. I have been feeling dizzy, weak and unable to lift my energy recently..."

Lin Feng carefully looked at the patient Yu Xianwei, and it did look like anemia.

"Your wardrobe, use mothballs?"

"Yes……"

"It's okay...Go and make a "blood routine"..."

billing.

The patient Yu Xianwei held the slip with a dazed expression on his face.

"Doctor Lin, this is over? I have waited for more than half an hour... You see me less than a minute..."

He was a little dissatisfied, so he could not ask for a few minutes. .

Lin Feng was amused: "I watched short, which means you are lucky, if you watch long, you will be in trouble..."

The patient Yu Xianwei was right when he heard it.

Suddenly left with joy.

...

Another hour later,

The patient Yu Xianwei returned.

· Blood routine: hemoglobin 75g/L (reference value 120-150)

Moderate anemia!

Lin Feng is happy!

Absolutely!

Two consecutive anemia.

Combining the taste of mothballs on Xianwei's body, an answer is ready to come out.

Broad bean disease!

That's right!

Mothballs can really be related to fava bean disease.

There is "naphthalene" in mothballs, which may cause hemolysis in fava bean disease.

(Because the mechanism of fava bean disease has not been studied, all the relevant ones are laboratory and empirical inferences)

The blood was supplemented first, and then Lin Feng gave the patient Yu Xianwei a "broad bean disease" examination item-g6pd.

Yu Xianwei left.

next moment,

Very coincidental,

The patient Zhang Suhua came back with the test results.

Lin Feng took a look at the result.

·G6pd project inspection: lower than normal...

confirmed,

It's "broad bean disease"!

In other words, Zhang Suhua's headache and dizziness are not the so-called "slightly narrowed vertebrobasilar artery."

It's fava bean disease, and long-term anemia caused by eating Doubanjiang.

Lin Feng told the patient Zhang Suhua:

"`" If you want to eat Doubanjiang in the future, change to one that does not have broad bean ingredients... and don't use antipyretic aminopyrine or phenacetin..."

Lin Feng remembered something and added:

"Are mothballs used at home?"

"Have……"

"Throw it away... You can't use mothballs... Take the clothes that smell like mothballs and slap them..."

"what…………"

The patient Zhang Suhua is dull...

Can mothballs have something to do with fava bean disease?

...

4 kilometers away.

A community,

A certain family, a group of relatives came to visit today.

In the living room, it is very lively, tea, fruit, all kinds of chat...

And in one of the rooms,

Chen Fengmei is lying on the bed (the king's) at this time.

She was awake, her eyes open, full of panic.

She can't move.

The whole body is just like being suppressed, and the heart feels a little heavy.

She remembered, but she couldn't get up at all, she couldn't move her whole body, and it was hard to move her fingers.

She could hear the noise outside the hall, but no one came in to see her, and one by one was still in hand: "Why can't your wife get up yet?" "Yes, is your wife sick?" "It's okay? , She is not sick..." "Is it because I was too tired yesterday?" "Haha~~~Young people pay attention to your body..."

Chen Fengmei: "......"

You guys are coming in!

I want to scold, but I can't open my mouth.

She was terrified.

As if constantly netting the dark abyss down.

Struggled for ten minutes,

Finally, she got a chance.

The mouth can move.

"Help!!!!!!"

20 minutes later...recognize...

Chen Fengmei was supported by her husband, got into the car, and rushed to the hospital.
