Fat people are more resistant to freezing than thin people.
It is because the fat layer of fat people is like a thick quilt, which effectively prevents the loss of body heat.
Zou Xuan, who is skinny and skinny, is not very afraid of the cold, which means she has heat in her body.
Suddenly realizing this, Yu Zhiming also realized his negligence.
When he examined Zou Xuan's body, he could clearly feel Zou Xuan's body surface temperature through physical contact.
Human body surface temperature is greatly affected by the external environment, ranging from twenty-seven degrees to thirty-seven degrees.
Yu Zhiming could still recall the feeling of performing physical examinations on Zou Xuan twice. Although it felt a little tingling to the touch, it was warm, and the body surface temperature should be above thirty-six degrees.
This is a normal value for body surface temperature, so Yu Zhiming naturally ignored it.
Now, Yu Zhiming asked the nurse to measure Zou Xuan's rectal temperature, which fell into the category of body core temperature.
Core temperature is a concept corresponding to body surface temperature. It is the body temperature referred to in physiology or clinical medicine and refers to the average temperature of the core area of the human body.
It is usually stable, generally 37.5-38℃.
Under different ambient temperatures, the scope of the core area of the human body will change.
In a cold environment, the core area is concentrated on the head, chest and abdomen; in a hot environment, the core area can extend to the limbs.
Core body temperature is not easy to measure. Clinically, rectal temperature (i.e. anal//temperature), oral temperature, and armpit temperature are usually measured to represent body core temperature.
Among them, rectal temperature is closest to body core temperature...
"Doctor Yu, the temperature was measured and it was 37.6 degrees. Is this temperature normal?"
"Do you have a fever?"
Yu Zhiming chuckled and said: "As long as the anal//temperature does not exceed 37.7 degrees, it is within the normal range."
"But this temperature is a bit too high for Zou Xuan, who is skinny and frighteningly thin."
Finally, an abnormality was discovered. Yu Zhiming said happily: "She doesn't have much fat in her body to keep her warm. She consumes a lot of energy to maintain such a core temperature."
As warm-blooded animals, humans need to maintain a stable body temperature, and maintaining body temperature consumes a lot of energy.
More than 50% of the energy the human body obtains through nutrition is directly converted into heat energy to maintain body temperature.
The rest is transferred to the body and converted into adenosine triphosphate into adenosine triphosphate, which is stored in the form of chemical energy to supply muscle contraction, nerve conduction, gland secretion, etc.
In order to obtain enough energy and maintain body temperature, you need to eat food constantly.
In contrast, ectothermic animals do not need to maintain a high body temperature and can survive for a long time after a good meal.
Take snakes as an example. Once a pet snake eats food, it usually takes about ten days to slowly digest it.
Zou Xuan's situation is even worse.
Her body lacks fat for insulation, and is like a dilapidated house with air leakage from all sides. In order to maintain the temperature of this house, she can only continuously increase the input of fuel.
This should be the reason why she doesn't eat much but is still so lean.
Most of the energy absorbed by the body is converted into heat to maintain body temperature.
Zhou Mo heard the change in Yu Zhiming's tone and asked, "Dr. Yu, have you discovered the reason why Zou Xuan is so thin?"
Yu Zhiming pondered and said: "In a situation like Zou Xuan's, the body core temperature should be 37.5 degrees, or even lower, to be considered normal."
"But judging from her rectal temperature of 37.6, her body core temperature should be 38 degrees, or even slightly higher."
"This body core temperature is a normal value for normal people, but for Zou Xuan, it is abnormal."
Yu Zhiming said thoughtfully: "I suspect that there is something wrong with Zou Xuan's body temperature regulation mechanism."
"so……"
Yu Zhiming warned: "Zhou Mo, ask the nurse on duty to tell Zou Xuan and her mother to prepare them..."
"Rush to Ning'an Hospital early tomorrow morning for an enhanced MRI of the hypothalamus."
The function of regulating body temperature is the hypothalamus deep in the brain, which is responsible for the anterior hypothalamus and the posterior hypothalamus.
The function of the anterior hypothalamus is to regulate the body's heat dissipation.
Assuming that the surrounding temperature rises, or when strenuous exercise is required, the hypothalamus will send a signal to trigger the body's perspiration function.
The posterior part of the hypothalamus regulates the body's rapid temperature rise to resist cold.
If the body is in a cold environment, the posterior hypothalamus will receive temperature signals from cold receptors and direct the subcutaneous blood vessels to reduce blood flow on the surface of the skin, lowering the skin temperature to slow down the loss of body heat.
The most important point is that the hub that regulates thyroid hormone secretion is the hypothalamus.
Thyroid hormone can promote the oxidative decomposition of substances and promote the body's production of heat.
This is why with hyperthyroidism, the human body becomes thin and most of the energy is converted into calories and consumed.
However, when Yu Zhiming examined Zou Xuan, he was able to confirm that there was no problem with her thyroid gland.
Yu Zhiming guessed that there should be some minor problems with Zou Xuan's hypothalamus, which caused Zou Xuan's body core temperature to remain at a level of 38 degrees higher than her body's needs, which consumed a lot of body energy in vain.
And this temperature level is also within the normal range of the human body, so the doctors who examined Zou Xuan before habitually ignored it?
This should be considered a kind of darkness under the light, right?
Because the hypothalamus is located deep in the human brain, it is a part that I cannot reach and cannot detect clearly.
Since Zou Xuan had had a brain examination before and found nothing, Yu Zhiming simply asked her to go to Ning'an Hospital to undergo an enhanced MRI examination with the highest accuracy...
It is said that men who work hard are the most attractive. Looking at Yu Zhiming's face shining brightly, Qing Ning also felt hot in her heart.
"Zhi Ming, have you solved another difficult disease?"
Yu Zhiming chuckled and said, "It's hard to say yet. We need to verify it with the MRI results coming out tomorrow."
"However, it is rare to find a suspicious point. The possibility of it being the cause of the disease is still relatively high."
This chapter is not over yet, please click on the next page to continue reading the exciting content! Qing Ning roared: "My family Zhiming is the best!"
"No. 1 in the world."
Yu Zhiming laughed and said, "You didn't drink much tonight, so why do you feel like you're drunk?"
"I'm not drunk, but everyone gets drunk."
Qing Ning looked at Yu Zhiming affectionately, and the moisture in her eyes was so wet that it felt like silk.
Zhou Mo looked a little blank, humming and joking: "How about we find an underground parking lot to park temporarily, and I can step aside for half an hour so that you two can do your work?"
Qing Ning glanced at her and said without much shyness: "Zhou Mo, when you have someone you love, you will understand what it feels like to be in love."
Yu Zhiming quickly said: "Okay, okay, don't talk about this topic, I'm still driving."
"Safety first! Safety first!"
Yu Zhiming took the initiative to change the topic and said: "The three basement floors of the old specimen building will be put into use this Friday."
"Zhou Mo, inform them all to report for work on Friday and familiarize themselves with the work environment."
Zhou Mo hummed and asked again: "Does Dr. Qin from the Traditional Chinese Medicine Department of Union Hospital also come to report on Friday?"
Yu Zhiming thought for a while and said, "Let him do it next Monday."
After a pause, he asked again: "Zhou Mo, will you go to Qiao Lei's wedding this Saturday?"
Zhou Mo hummed and said, "After all, we are colleagues in an office, so we have to give him face."
"Also look at the level of their wedding banquet."
Yu Zhiming added: "When you present the gift, you can compare with Dr. Han and thank Dr. Han and his colleagues for their skill and give me a red envelope."
Zhou Mo said "Okay" and then asked: "Doctor Yu, has the location of your wedding banquet been confirmed?"
Qing Ning replied: "It hasn't been decided yet."
"My eldest brother's wedding banquet is scheduled for today at the Lijing Hotel. My dad said that my eldest brother's and I's weddings are a bit close together. If we are in the same hotel, the taste of the banquet will inevitably be the same."
"He is looking for other suitable locations."
"It's just that there are a lot of guests, and there aren't many restaurants that can host it. Some good places have already been booked."
Qing Ning said cheerfully: "My dad also said that there is a solid plan, which is to find a suitable open space to hold an open-air wedding and an open-air banquet."
Yu Zhiming smiled and said: "This plan is not bad."
"In our rural areas, banquets for weddings and banquets are basically open-air."
Zhou Mo expressed his opinion: "Qing Ning, your wedding is in late October. The autumn weather is crisp and clear at that time, so it is perfect to hold an open-air wedding."
"The only thing I worry about is the weather and typhoons."
Qing Ning hummed and said, "This is what my dad is worried about, so the open-air wedding is just a back-up plan."
Zhou Mo said hehey: "There are many ways to do an open-air wedding, including helicopters, hot air balloons..."
Yu Zhiming interrupted: "No need for new tricks, just follow the traditional wedding steps."
"New tricks mean new unexpected risks."
Zhou Mo curled his lips and asked: "Dr. Yu, I guess you have never done bungee jumping, right?"
Yu Zhiming said with a look of disgust: "What's so fun about bungee jumping? If you're not careful, there will be dangers such as temporary blindness, joint damage, syncope and shock. It's a typical waste of money."
Zhou Mo asked again: "Qing Ning, you must have played with it before, right?"
Qing Ning said with some guilt: "When I went out to play with my friends before, I was encouraged to play."
She added: "It doesn't feel very good. It's true as my family Zhiming said, it's just spending money to buy suffering..."
Time flew by unknowingly as the three of them chatted. At ten ten o'clock in the evening, they returned to Junshan Mansion.
After entering the elevator, Qing Ning clung tightly to Yu Zhiming's body, her little body still twisting and turning.
"Husband...husband..."
Yu Zhiming hugged this guy to prevent her from moving, and reminded: "Why are you so anxious? There are surveillance cameras in the elevator."
"Hehe, don't be afraid, it's not too much to hug each other..."
As soon as she entered the house, Qing Ning couldn't wait to jump on Yu Zhiming's body. A pair of powerful and elastic long legs were firmly tied around Yu Zhiming's waist.
Yu Zhiming was about to respond enthusiastically, but he noticed something was wrong in the living room and said hurriedly: "Come down, come down first."
Qing Ning roared: "Auntie should be asleep. She won't come out even if she hears any noise."
"Husband, we are not afraid no matter what we do..."
At this moment, a clear cough suddenly sounded.
Hearing this sound, Qing Ning slid down from Yu Zhiming's body and hid behind Yu Zhiming like a monkey.
The next moment, she poked half of her head out, looked at the two people in the living room, and said with a red face: "Mom, aunt, why are you here?"
"Why don't you call and tell us in advance?"
When Yu Zhiming saw his mother-in-law and Aunt Qing Ning suddenly appearing in his home, he felt much more nervous than Qing Ning.
