Tokyo: A leisurely life starting from the countryside

While Yukishi was cooking, she was also grinning beside him.

No matter what Yuuki did, she would watch and smile foolishly.

Mika Takizawa hasn't sent any messages to Tsuyoshi Yuuki since they last parted.

There has been no contact for nearly two weeks now.

Yuki Shi had not contacted her on his own initiative, as some things needed to be thought through before being discussed.

Overall, life was pretty peaceful.

Yukishi looked at the blood gas report in his hand and said calmly:

"Teacher Yoko, your potassium is normal. Don't worry too much. It's normal for the arterial potassium concentration to be slightly lower than the venous potassium concentration."

Yoko is a woman in her forties, and is also a teacher at Yuuki Shi Kindergarten.

But at that time, Yoko was still a young and beautiful girl. Now, Yoko has a serious face, flat eyebrows, and her eyes no longer have the cuteness and longing she once had.

Some people only have strong questioning and intimidation without being angry.

She was feeling unwell some time ago and had a physical examination in Tokyo, and was found to have low potassium. She then took some medicine and ate some food as recommended by the doctor.

Now is the time for a follow-up examination, but if you go to a large hospital for a follow-up examination, the medical fees and commuting expenses will be a huge expense.

Forty years old is the time when you have to tighten your belt to support your parents and children.

Naturally, she was reluctant to spend the money, but she also wanted to have her body checked again.

Among the several clinics on the island, only Yuki Tsuyoshi's Yokomitsu has equipment that can check electrolytes.

After finding Yuki Si and explaining his purpose, Yuki Si naturally would not refuse.

I drew blood gas myself and started the test.

When the results came out, the blood potassium concentration was 3.3mmol/L, which is a normal concentration in arterial blood potassium.

However, it is 0.2 lower than the normal value of venous blood potassium concentration.

As a teacher, Yoko is naturally more sensitive to numbers than ordinary people.

She clearly remembered what was written on the results of her last blood test.

The normal value of blood potassium concentration is 3.5-5.5mmol/L.

My blood sugar is 3.3mmol/L, why does Yuki Shi say it is normal?

Isn't this obviously bullying her because she doesn't know medicine?

He came to the door with a dark face.

This is why Yukiro Si said that just now.

But faced with Yuki Shi's explanation.

Of course Yoko wouldn't believe it.

She looked up relevant knowledge on the Internet herself.

It is said on the Internet that there is actually no obvious difference between venous blood potassium and arterial blood potassium.

Simply put, the values ​​of the two should be the same.

Yoko yelled at Yuuki with a gloomy face:

"Yuuki Shi, you graduated from my class when you were a kid, did I teach you how to deceive everyone?"

"My potassium level is obviously problematic, but you still say it's fine. Aren't you bullying me because I don't know medicine?"

"How did you become like this now? You were very sensible and obedient when you were a child!"

"Now I've even deceived the teacher!"

Several people who were about to see the doctor stood at the door and dared not come in after hearing the voice.

They heard that Yuki Tsukasa's skills were good, so they came here specifically for treatment.

However, I heard this quarrel before I even entered the house.

It seems that the patient is Yuki Si's former teacher. Yuki Si even deceived his former teacher. Not to mention his medical skills, his character must not be very good either.

Some things really need to be seen with your own eyes to be known.

I saw more and more people gathering at the door.

Mizuno Mika started to panic and wanted to explain for Yuuki Tsukasa.

But she herself didn't understand and didn't know how to start.

All we can do is be anxious.

Yuki Shi's expression was calm as he looked at the ferocious woman in front of him.

There is absolutely no way to connect with the "godlike" sister in my childhood.

"Teacher Yoko, please don't get excited. It doesn't matter if you don't understand this. I can explain it to you."

Yukishi got up from his seat, glanced at the crowd outside the door, and said with a smile:

"Fellow villagers, please come in and listen. I can also give you some basic knowledge. It will be beneficial for everyone to know more."

The people at the door looked at each other, and finally decided to go into the house.

Yuki Shi has treated many people in the past two months, and his reputation and word of mouth are actually quite good.

There is no harm in listening more.

When almost everyone came in, including Yoko, there were eight people in total.

Fortunately, the hall is quite large and just enough space for sitting down.

Yuuki Si stood among the crowd with a faint smile on his face and his eyes were gentle and confident.

There is a calm and peaceful aura about the whole person, which makes people obsessed.

Mika Mizuno looked at Yuuki Shi obsessed, biting her lips gently, her eyes full of love.

"Okay, everyone, take your seats. Let me first tell you the main reason for this incident."

"Teacher Yoko was diagnosed with hypokalemia during a physical examination in Tokyo half a month ago. Simply put, the potassium ions in the blood are low. Under the guidance of the doctor, Teacher Yoko also received corresponding treatment. She came to me for a follow-up examination today."

"But I only have an electrolyte blood gas analyzer here, which draws arterial blood, while Teacher Yoko checked venous blood in Tokyo, which means one draws blood from the wrist and the other draws blood from the elbow. Is that right, Teacher Yoko?"

Yoko didn't sit down, but folded her hands in front of her chest. When she heard what Yuki Si said, she just nodded and didn't say much.

Chapter 152 Popular Science

Yukishi nodded and continued:

"The reason why I asked everyone to come together is to educate everyone on the harm of low potassium and high potassium to everyone."

"Potassium ions are very common electrolytes in our body, similar to trace elements such as chloride, calcium, magnesium and iron, and are an element that maintains the basic life needs of the human body."

"But this element is in a relatively balanced range in everyone's body. That is to say, it can't be too much or too little, just the right amount."

"The potassium ions in our body are mainly found inside cells. There are also some outside cells, but in relatively small quantities. Together with other ions such as hydrogen ions and sodium ions, they maintain the acid-base balance in the body, so that our body will not get sick."

"Once these balances are broken, people will have problems, such as low potassium. If the potassium ions are too low, the most common feeling we have is general weakness and feeling like we can't lift our legs. If any of you feel this way, you should pay attention to it."

Yuki Tsutomu first briefly explained the role of potassium ions to everyone, and saw the feedback from everyone's eyes.

Yuuki Shi found that they didn't seem to understand much.

After thinking for a while, Yukishige said again:

"In fact, to put it simply, everyone just needs to remember that if you feel weak in your limbs and have no energy, it may be that the potassium in your body is low. Do you understand?"

This time a few people nodded, probably remembering it.

Yuki Shiyou asked Yoko:

"Teacher Yangzi, did you feel any discomfort when you were diagnosed with hypokalemia?"

Yoko frowned and thought for a moment. She didn't have breakfast on the day she went for the check-up.

She did feel weak at the time, but she didn't pay much attention to it, thinking it was because she didn't have breakfast.

"I did feel a lack of strength that day."

Yoko answered honestly.

Yukishi nodded and continued:

“In addition to low potassium, there is high potassium, which means that the potassium ions in the body are high, and the diseases caused by this disease are more serious.

Because potassium ions affect the contraction of myocardial cells, hyperkalemia can easily lead to cardiac arrest, which is a very dangerous disease and can be fatal.

When everyone heard Yuki Si say that someone was going to die, their expressions became serious.

"Doctor Yuki, how do we check for hyperkalemia? Does he have any other symptoms?"

When someone asked, Yuuki Shiya smiled and said:

"I know everyone is worried about this issue, but you have to know that our body's regulatory function is very strong. Generally, if the temperature is a little bit higher, the body can adjust itself."

"What's rare is that a large amount of potassium ions suddenly increase, or the body's regulatory function deteriorates..."

After a few words, Yuki Si noticed that the expressions of several people became strange again.

Probably he didn't understand.

Yuki Si smiled bitterly, there was nothing he could do, after all, they didn't understand these things.

After another silence, he continued:

"It doesn't matter if you don't understand. Just remember the few diseases I mentioned. As long as you don't have these, generally speaking, hyperkalemia will not occur."

"High potassium, since it is high, it means two problems. The first is that the source is too much, and the second is that the excretion is too little."

"There are many sources. The simplest ones are large-area burns and radiotherapy and chemotherapy for cancer. Because potassium ions are inside cells, these two diseases will destroy a large number of cells, causing potassium ions to flow out of the cells and affecting potassium ion balance."

"If the excretion is too little, it means kidney disease. People with kidney disease are prone to hyperkalemia because potassium ions are excreted from the kidneys. If there is a problem with the kidneys, potassium ions naturally cannot be excreted."

"And then there's acidosis, acidosis..."

Yuki thought about it for a while and felt that the concept of acidosis was not that easy to understand, so he just said:
