My daily work as a doctor: My treatment value is increasing.

Fortunately, Lu Renxin was lucky. The high-speed train was forced to stop at two stations due to overloading, and he thought he would be kicked off the train and unable to go back.

However, under the guidance of the train attendants, the passengers in the alarm-stricken carriage were gradually dispersed to other carriages, and the high-speed train continued to depart.

After finally arriving at Xinyang City High-Speed ​​Railway Station, Lu Renxin's legs were numb from squatting. He left the carriage with the crowded passengers.

He had to rush to the bus station to catch a bus before he could reach his home in Anyuan County.

The wheels rolled over the slightly bumpy asphalt road in the countryside, kicking up clouds of dust. Lu Renxin leaned against the window and looked out through the glass.

In early May, the Central Plains are covered with endless fields of lush green wheat.

Now is the crucial period for wheat grain filling. In a while, this lush green will turn into a golden yellow that represents maturity.

This is his hometown, the place where Lu Renxin was born and grew up.

……

More than an hour later, the bus finally arrived at the entrance of Anyuan County People's Hospital.

Anyuan County is small, with a small permanent population, and only two public hospitals in total.

One is Anyuan County Traditional Chinese Medicine Hospital, and the other is Anyuan County People's Hospital.

In the early years when the county's economy was not doing well, both hospitals were dilapidated.

In recent years, thanks to favorable policies, the hospital has developed rapidly and has been completely renovated. It looks quite impressive after the renovation, and its level has been upgraded from Level II-B to Level II-A.

Travel-worn Lu Renxin followed the instructions given to him by his mother, Li Ailan, and weaved through the patients coming and going in the emergency room.

They finally found his father's observation room number 25 in the maze of beds.

It's not the ICU, and there's no hospitalization; it's just observation (the formal hospitalization procedures are not being completed yet, but the patient needs to stay in the hospital for treatment or monitoring).

He was not unconscious or disoriented; his complexion was slightly pale but otherwise normal. Lu Renxin's anxiety finally subsided.

Lu Huaishan looked at his son, who was carrying a large bag and looked travel-worn, and his face was full of excitement: "Xinxin's back! Have you eaten yet?"

He was about to get up, leaning against the bed rail, when Lu Renxin reacted quickly, taking two steps forward and grabbing his father's shoulder:

"I've eaten, Dad, don't worry about me anymore. Just lie there and don't get up!"

In fact, he only ate some bread and instant noodles on the way, because he was worried about his father's illness and had no appetite.

After unloading his heavy backpack and tossing it under the bed, Lu Renxin plopped down on a chair by the bed.

The most important thing now is not whether he is hungry or not, but why Lu Huaishan suddenly fainted.

His mother, Li Ailan's, description over the phone was so frightening that he was terrified the whole way.

He turned to look at his mother, who was busy helping out, his eyes questioning:

"Mom, what exactly happened this morning? You said on the phone that Dad suddenly collapsed to the ground and couldn't be woken up no matter what you did..."

Upon hearing this, Lu Huaishan's previously relaxed brows furrowed, and he glared at Li Ailan unhappily.

"You're exaggerating. I'm fine, I'm in great health. Look at you, sending your son back from Guanghai is a waste of money and time."

Li Ailan pouted, looking aggrieved, and paused in her act of peeling the apple.

"How can you blame me? The moment you collapsed, your face was deathly pale, and I couldn't wake you up no matter how much I called. How could I not be anxious?"

"What if something happens to my son if I don't call him back?"

He is lucid, articulate, and can even argue with his mother; he seems to be fine.

His gaze fell on the thick stack of medical examination notices on the bedside table.

Lu Renxin picked them up casually; there were echocardiograms, cranial CT scans, chest CT scans...

Lu Huaishan saw him pick up the list and started grumbling again:

"I'm perfectly fine. Look at all the tests they did, they drew so many vials of blood, my arm is all bruised, I don't even know how much it cost."

The father was worried about the money, but Lu Renxin knew in his heart that the doctor had not ordered these tests for nothing.

The causes of sudden fainting are very complex, including cardiogenic syncope, vasovagal syncope, orthostatic hypotension, cerebral and metabolic syncope, etc.

All of these need to be ruled out through laboratory tests and examination results.

Just like solving a case, you need to find unusual clues to narrow down the scope, filter them, and finally find the murderer.

Hospitals are now keeping up with the times, and all the results can be found on their official WeChat accounts.

Lu Renxin took out his phone, followed the hospital's official WeChat account, linked his father's medical card, and quickly saw the results.

He swiped his finger across the items one by one.

Blood tests were normal, myocardial enzyme levels were normal, troponin levels were normal, and the cranial CT scan showed no major issues...

Most indicators were within the normal range, except for one indicator which was highlighted in red and bold.

Fasting blood glucose: 2.6 mmol/L, far below the lower limit of normal (3.9 mmol/L).

Lu Huaishan already has diabetes and needs to take medication regularly to control his blood sugar.

But for patients like him, it's not just high blood sugar that needs to be guarded against, but also low blood sugar.

There's a famous saying in the medical field: "High blood sugar is a slow poison, while low blood sugar is an acute killer."

The harm of high blood sugar is usually gradual. In a long-term high-sugar environment, blood vessels, nerves, eyes, and kidneys will be damaged, much like pickled fruit.

However, the process is quite lengthy, taking several years or even decades.

The dangers of hypoglycemia are precipitous, as the human brain relies almost entirely on glucose in the blood for energy.

Mild hypoglycemia can cause palpitations, tremors, and cold sweats.

Severe hypoglycemia can cause irreversible brain damage.

A sudden interruption of energy is like a computer being unplugged, leading to sluggishness, decreased intelligence, coma, or permanent brain damage.

Lu Renxin had reminded Lu Huaishan before to keep his blood sugar stable, but he still didn't listen.

"Dad, did you take insulin this morning and not have much of an appetite, so you didn't eat?" He put down his phone, his tone serious.

Lu Huaishan's eyes flickered, and he stammered, "I'm not that hungry. I was thinking that skipping a meal would help lower my blood sugar."

"That's the reason." Lu Renxin sighed, his tone tinged with helplessness. "The medicine has already started working, depleting the sugar in your blood, but your body doesn't have enough."

"It's like a car still running, but the fuel tank is empty; can the engine stay running?"

Lu Renxin glanced at the doctor's diagnosis by the bedside; it was indeed hypoglycemia. It seemed that this fainting spell was caused by it.

Fortunately, his mother was nearby and took Lu Huaishan to the hospital in time, preventing serious injury.

He put down the report and solemnly reiterated to Lu Huaishan the importance of maintaining stable blood sugar levels.

"Dad, remember this from now on: you must eat after getting a shot, even if you can't eat, you have to force yourself to eat a few bites."

Seeing his son's serious expression, Lu Huaishan finally realized the seriousness of the problem and nodded silently.
