The difference between normal thinness and cancer thinness, although we are all pursuing thinness for beauty now, cancer patients may not lose weight, because emaciation is one of the common signs of human cancer, so what is the difference between normal thinness and cancer thinness?

The difference between normal thinness and cancer thinness 1 The characteristics of cancer thinness and normal thinness are as follows:

First, cancer weight loss occurs rapidly in a short time, and there is no clear cause before weight loss occurs. Ordinary emaciation generally has a slow course of disease, and there are usually incentives such as reduced food intake and anxiety before emaciation.

Second, weight loss of cancer is often accompanied by clinical symptoms of cancer such as fever and edema.

Ordinary emaciation is generally only manifested in the body, and there are no other accompanying symptoms in most cases.

First, patients are under great psychological pressure.

After suffering from cancer, people's psychological pressure will suddenly increase. I will worry about how my descendants will live, I will be afraid of death, and I will even be afraid of seeing a doctor and taking medicine.

If this negative emotion cannot be effectively regulated, it may even lead to a series of syndromes such as palpitation, anxiety and insomnia. The imbalance of neuroendocrine system will affect the operation of digestive system, leading to loss of appetite and indigestion. After a long time, people will become thinner.

Second, the energy plundered by tumor cells.

Normal human cells will die automatically after 50-60 times of fission. However, tumor cells grow geometrically and are not easy to die. With their rapid growth, they need to absorb more energy and even begin to plunder normal cells, tissues and organs.

If the patient eats according to the usual appetite, it is far from enough to fill the tumor cells, so it will become thinner.

Third, the treatment of physical torture

If you have cancer, you must receive treatment. Whether taking anticancer drugs or radiotherapy and chemotherapy, it is actually very harmful to the body. We often say that cancer is terrible, and the treatment of cancer is like the process of "fighting poison with poison". Killing 3000 enemies will hurt 800. After taking the medicine, we temporarily stabilized the cancer cells, but also produced side effects such as nausea, dizziness and vomiting. Chemotherapy and radiotherapy are even more terrible. The radiation they produce will cause irreversible damage to human body and organs, affect the absorption of human digestive system, and lead to malnutrition of patients.

Generally speaking, cancer is very harmful to human body. If someone around you is unfortunately suffering from cancer, you must let him learn to face the disease positively and optimistically, supplement more nutrition and take care of himself, because he will be able to fight cancer cells when he is strong.

The difference between normal thinness and cancer thinness 2 The difference between cancer thinness and ordinary thinness: The difference between cancer thinness and ordinary thinness is first reflected in the speed of thinness. Cancer patients will lose weight very quickly, and there is no clear reason before weight loss occurs. The body weight can be reduced by more than 10% within half a year, and the weight loss is irreversible. Ordinary emaciation generally requires a process. Before emaciation, there are generally incentives such as diet reduction and anxiety.

Secondly, common emaciation generally has no other symptoms except emaciation. Part of emaciation is due to weight loss and less nutrition intake, and part of emaciation is caused by pathological factors, such as hyperthyroidism, diabetes, liver cirrhosis and hepatic ascites. Cancer wasting may cause some symptoms, such as nausea, abdominal pain, bloating, loss of appetite, persistent body pain and lumps on the body. Some cancer patients will lose 10 kg a month, so many people find cancer because of excessive weight loss.

Thirdly, normal emaciation is a normal physiological process, generally due to the decrease of food intake and/or the increase of consumption. For example, physical exercise leads to the decrease of muscle and fat tissue, while cancer wasting is because cancer cells need more nutrition than normal tissues, which leads to the progressive decrease of normal muscle, fat and other tissues.

Another reason is that cancer cells will produce a lot of toxins during metabolism, which obviously weakens the digestive and absorption function of patients' gastrointestinal tract, leads to a significant decline in nutrient intake and absorption, and further aggravates the loss of muscle and adipose tissue and weight loss. After getting cancer, patients will also feel depressed and don't want to eat, which is also the reason why cancer is thin.

1. Why are cancer patients getting thinner and thinner?

A study in the British Medical Journal analyzed the clinical characteristics of sudden weight loss, and the results showed that there was a close relationship between weight and cancer risk.

In this study, researchers from Oxford University and Exeter University analyzed the data link of clinical practice research, and the data involved 64,000 subjects. The researchers counted the clinical characteristics of the subjects after sudden weight loss. About 908 subjects developed cancer within 6 months after diagnosis and treatment of sudden weight loss.

After adjusting for smoking, drinking and other factors, further analysis found that the subjects who suddenly lost weight were twice as likely to develop cancer as those who did not suddenly lose weight. The most common is lung cancer, followed by colorectal cancer, gastric cancer, esophageal cancer, pancreatic cancer and lymphoma.

What causes the patient to lose weight?

1, nutrition is contested by cancer cells.

The growth of cancer cells also needs nutrition, and its energy source is not much different from that of healthy cells, and it also depends on glucose. Originally, the human body only needed to maintain normal cells, but now it has to "feed" cancer cells. When the nutrition consumption is high, the patient's weight is easy to drop.

2. Gastrointestinal tumors affect digestion.

Cancer cells that grow in the digestive system such as esophagus and stomach will directly affect the body's absorption of food nutrition. When patients can't absorb and digest normally, their weight is also easily affected.

3. If it has been diagnosed, the treatment will also affect it.

For patients who have been diagnosed, radiotherapy and chemotherapy should be started. In the course of treatment, due to the effect of drugs, the body will inevitably produce side effects, such as oral ulcer and loss of appetite. , may cause weight loss.

Second, what diseases can also lead to weight loss?

Of course, the sudden weight loss is not necessarily caused by cancer cells. The following diseases are also related to the digestive system. When the patient is sick, it may also affect the appetite and lead to weight loss.

1, anorexia nervosa

Most of them are women, and the onset age is earlier than 25 years old, which is related to serious emotional disorders. It may be due to health concerns and stubborn prejudice against diet, nutrition or weight. Emaciation may be accompanied by amenorrhea, bradycardia and paroxysmal anorexia.

2, chronic hepatitis, liver cirrhosis

Affected by chronic liver disease, patients' liver function gradually declines, the function of liver to synthesize and store glycogen declines, and the synthesis of protein also declines, which affects patients' appetite and digestion and absorption of food, and may lead to emaciation.

3. Depression

People with depression will not only suffer from depression, inferiority, lack of self-confidence and slow thinking. And with the aggravation of the disease, it may be accompanied by symptoms such as sleep disorders and loss of appetite.

4. Hyperthyroidism

Hyperthyroidism patients, due to thyroid dysfunction, affect the normal operation of endocrine, will appear fear of heat, sweating, impatience, palpitations, exophthalmos and goiter, diarrhea, emaciation and other symptoms.

The difference between normal thinness and cancer thinness 3 First of all, cancer thinness is generally unexplained weight loss. If you haven't been dieting and exercising recently and your weight has been dropping continuously, that's an abnormal performance. Normal thinness is weight loss caused by deliberate dieting and weight loss.

Secondly, cancer and thinness generally lose weight faster in the short term, while normal thinness has a gradual process. In addition, cancer thinness is mostly in the middle and late stages of the disease, and it is usually accompanied by other discomfort symptoms, such as loss of appetite, while normal thinness is generally not accompanied by other discomfort symptoms.

The energy consumption of tumor tissue is almost crazy.

Most normal cells replicate and divide 1 time every 5-6 days. After dividing 50-60 times, it will die and its metabolism will be normal. The division of cancer cells is 1 minute 2, 2 minutes 4 ..., which increases geometrically, without the meaning of automatic apoptosis, leading to infinite proliferation of tumor tissues!

The tumor is so small that it can only survive by "supporting" adjacent tissues. As the tumor grows up day by day, I can't eat enough. Won't it starve to death Do something! Autogenous blood vessels are "illegally" connected with systemic blood vessels. In order to rob other tissues of nutrients, the faster the proliferation, the more nutrients they rob, and the faster the patient loses weight!

Is it feasible to starve tumors by not eating or eating less? No matter how much tumor tissue you eat, it grabs more and eats more. If so, other tissues and organs will starve to death.

Treat malnutrition caused by side effects.

Cancer definitely needs a series of treatments, and these treatments are also one of the key factors that cause malnutrition in patients, such as digestive system surgery, such as gastrectomy and hepatobiliary surgery; The latter's direct radiation exposure to digestive organs, central vomiting caused by chemotherapy drugs and damage to digestive tract mucosa have caused serious loss of appetite and digestive absorption disorders. After such a long time, patients will inevitably suffer from malnutrition.

The patient's nutritional intake may be problematic.

Some metabolites secreted by tumor tissue will affect patients' appetite and even nausea and vomiting.

Different tumor types have different effects on food intake. For example, digestive tract tumors, in addition to not wanting to eat, may also have digestive tract obstruction and become "unable to eat." However, non-digestive tract tumors such as breast cancer, thyroid cancer and lung cancer have relatively little effect on nutrient intake.

Emotional factors can also aggravate malnutrition.

After the occurrence of cancer, many people are afraid, so they are under great pressure. However, if not adjusted in time, these negative emotions will affect the movement of digestive system through neuroendocrine mechanism, reduce the secretion of digestive juice, and lead to a decline in appetite. After a long time, patients will have symptoms such as malnutrition and weight loss. The appearance of these symptoms will constantly remind patients of the existence and deterioration of tumors, which is easy to produce negative psychology and form a vicious circle.

Weight loss is mostly in the middle and late stages.

The contradiction between decreased intake and increased consumption results in weight loss and emaciation of patients. Among them, the consumption is directly related to the tumor size and the number of lesions. The more cancer cells, the greater the consumption, so consumption is more common in patients in the middle and late stage, especially in patients in the late stage. Malnutrition and emaciation will lead to the decline of patients' immunity, accelerate tumor growth, and may lead to a series of complications, endangering patients' lives.

The main treatment principle of malnutrition in tumor patients is to make a reasonable nutritional supplement plan for tumor patients: if tumor patients can eat normally, they should follow the dietary principle of treating malnutrition in tumor patients, mainly soft food with high energy, high protein and easy digestion, and eat less.

Pay attention to supplement high-quality protein. You can eat more nutritious foods such as fish and shrimp, lean meat, eggs and milk. At the same time, pay attention to avoid those foods that are unfavorable to your condition, such as spicy, irritating, greasy, fried and other foods. For patients with severe malnutrition, simple diet conditioning is mostly impossible. At this time, it is necessary to treat under the guidance of a doctor.
