Whether a person can eat and whether the food can be digested by the body is equivalent to whether a car can be refueled and charged, and whether it can convert energy after refueling and charging. If not, the car will not run and the person will break down like a machine.

What makes life far more cruel than machines is that life will die when it stops functioning.

People's diet is very important, which is called nutrition in clinical practice. The nutrition department of the National Association is the most famous in the country. Fu Xinheng consulted with Zhang Huayao:

"If the teacher can't eat, is there intravenous nutrition?"

Not being able to eat means that the patient's gastrointestinal tract cannot afford to convert energy, not that the mouth cannot eat. In this case, nasogastric or enteral nutrition is not very effective, and the only option is to seek intravenous nutrition. Intravenous nutrition can directly supplement energy to the human body without conversion through the digestive system. This way of supplementing nutrition has its flaws, as mentioned before, but it is the only option for seriously ill patients to prolong their lives.

If possible, Zhang Huayao didn't want to give his mother these injections, because it meant that his mother's health was getting worse. Unlike other diseases, patients with advanced cancer can't recover after a short period of energy replenishment. It would be best if the patient could make an effort and try to eat again.

Looking at his mother working hard to eat, Zhang Huayao's dark eyes were as motionless as frozen soil, and his gaze seemed to be wandering far away.

Seeing that he didn't speak, Fu Xinheng could feel that his heart might not be at peace.

When a patient is sick, it not only tortures the patient himself, but also tortures the patient's family members who love the patient.

Is it useful to be a top medical scientist? In a situation like this, it is still useless.

Boss Zhang had a subtle expression on his face. He Xiangyu and Liu Jingyun couldn't help but start nagging when they avoided Teacher Lu.

"Could it be that Teacher Lu's condition means that the cancer cells have spread throughout his body?" Liu Jingyun didn't dare to think of the worst speculation and burst into tears when she thought about it.

"Big sister." As someone from the pathology department, He Xiangyu knew some gossip, so she told the truth, "Before Teacher Lu had the surgery, they evaluated that the cancer cells might have spread to other organs. Brother Tao and the others insisted on having the surgery, not only to buy Teacher Lu a longer life, but more importantly, they were afraid that Teacher Lu would end up like Teacher Zhang."

During the last period of his life, Teacher Zhang Yuqing was tortured by illness and had no dignity at all. He was neither a human nor a ghost. Tao Zhijie and his team would never allow such a mistake to happen again.

If a teacher wants to leave, he must leave with dignity and respect. This is the obligation that students must fulfill for their teachers.

Tumors not only cause patients to suffer from pain, but also invade their organs and tissues, causing them to lose related body functions and gradually lose everything including dignity at the end of their lives. Therefore, painkillers alone are not enough to solve the pain of patients, and surgical methods must be used when necessary.

At this time, surgery is no longer aimed at curing the disease, because we know that the disease cannot be cured. However, surgery can make the patient live a happier life, which is another goal pursued by surgery and one of the directions that surgeons work towards.

"Don't worry, we won't give up on Teacher Lu." He Xiangyu said to the senior sister, "Look, the robot came here in person to have dinner with Teacher Lu. It's impossible for them to just go to the teacher's house for dinner."
