Why do cancer patients lose so much weight?

Because the cancer cells in the body are spreading, their own healthy cells are engulfed, which leads to a gradual decline in body functions, and there is no way to achieve normal diet and exercise, which will cause rapid weight loss.

Because after getting cancer, tumor cells will consume a lot of human energy in the process of growth, and these energy consumption exceeds the total energy value of the human body normally obtained from food, so that the body's energy metabolism begins to grow negatively, and in the long run, the patient will have wasting performance, and weight loss is inevitable.

Cancer patients are unable to take in adequate nutrients. While cancer patients are taking in nutrients, cancer cells are also fighting for nutrients, which consumes a large amount of nutrients in the human body, and weight loss is inevitable.

You can't eat for a few days after chemotherapy.

Cancer patients have a good appetite after surgery and actively supplement nutrition. Lung cancer patients have little impact on digestion. If the wound heals quickly after the surgery and their family supplements the patient with a lot of nutrients, others will gain weight at this point.

In fact, weight gain is a good thing for patients and is beneficial for the recovery of various organ functions.

If the patient gains weight in the process, it means that the nutrition is good, which is a good phenomenon, but the weight gain does not judge the effect of the cancer and whether the cancer is good. In general, cancer is mainly a combination of sexual surgery and chemotherapy and radiotherapy.

The judgment of clinical ** is that the patient reaches clinical ** after positive**, but this does not mean that there will be ** and metastasis in the future, but the probability of ** after 5 years is low. Appetite improves, diet and ** active nutrition; Some patients are treated with hormonal drugs during chemotherapy, resulting in water and sodium retention. Severe hypoproteinemia in advanced patients can lead to edema in the body, which indicates a poor condition.

If the surgery of a cancer patient does not have much effect on the digestive tract, so it does not affect the patient's appetite, and the surgical wound heals quickly, it is easy to gain weight. Some patients use some medications that contain hormones during chemotherapy. These medications can help reduce gastrointestinal reactions such as nausea and vomiting, which can also increase the patient's appetite and eat a lot of food, naturally increasing their weight.

However, weight gain at this time is not a good thing because it is caused by hormones, which have a great *** effect on the body. Cardiac obesity occurs when hormones are used more, leading to the storage of water and sodium.

Many cancer patients have no effect after surgery, but their appetite will become very good; Because if the surgery has no effect on the digestive tract, it will not affect the appetite, so this is also one of the causes of weight gain.

At this point, weight gain is actually a good situation. After the surgery, the nutrients are absorbed and the body slowly recovers. However, if patients with gastrointestinal tumors, such as esophageal, gastric, and liver cancers, are affected by surgery, it is relatively difficult to eat. At the same time, they may also lose weight.

Some patients with advanced disease gain weight over a short period of time, which may be due to edema due to severe hypoproteinemia. As the protein is too low, the colloidal osmotic pressure decreases, resulting in a large amount of water trapped in the blood vessels, resulting in facial edema and lower extremity edema. At this point, although the patient has gained weight, this is not a sign of improvement.

In contrast, there is a renal excretion disorder. The patient's family and physician should examine it carefully.

In general, the management of body weight for cancer patients is still more important, too light weight and too obese weight are not good for cancer patients, because in the process, maintaining a moderate body weight is more helpful.

If there is weight gain, it is likely that some hormones in the body have changed, then it is not a good sign and should be noted.

Weight gain in cancer patients may generally be related to the drugs they eat, many of which contain too much hormones, so they will cause the body to gain weight. It doesn't mean it's a good sign, or a bad sign.

If cancer patients have weight gain, on the one hand, it is due to their own recovery is better, and on the other hand, it may be due to ascites in the body, which is not good.

Almost all cancers are accompanied by symptoms such as weight loss.

Why do you lose weight?

To put it simply:

First, cancer cells need a lot of energy to proliferate wildly, which inevitably robs our normal body of the energy it needs.

Second, cancer cells can affect our digestion and absorption, protein and growth, hematopoiesis and other functions;

Patients with advanced cancer experience a variety of symptoms, such as vomiting and diarrhoea, which not only deprive nutrients, but also cause dehydration and electrolyte imbalances.

In addition, bleeding, infection, fever, chest and ascites, proteinuria, etc., cause a large amount of nutrients to be lost, making the patient emaciated.

Clause. 3. After chemotherapy and radiotherapy, it affects appetite and digestion;

Fourth, some patients will have anxiety, insomnia, and loss of appetite due to cancer, which is psychoanorexia. In addition, cancer cells can produce a large amount of Kai tremor toxin in the process of metabolism, which can suppress the patient's appetite, resulting in loss of appetite, decreased food intake, insufficient nutrient intake, and natural weight loss.

All cancers can cause emaciation, and due to the activity of cancer cells in the body, they can cause the body to be emaciated. It is still recommended that if there is obvious weight loss, go to a regular hospital immediately**, do not delay the condition, and detect it early**. Of course, weight loss is not completely sure that it is cancer, and it may also be caused by other physical discomforts, so it is hoped that patients will pay more attention to the changes in their body and carry out it as soon as possible**.

I personally felt the torment of parotid gland cancer, and I couldn't eat anything during chemotherapy and radiotherapy, which dropped from 140 to 95 pounds, and now I have recovered to 110 pounds.

Excluding standing water, all advanced cancers lose weight.

It is lymphoma, which seriously affects the diet, and it will also cause muscle atrophy, so it is strange that it is not thin.

Not clear, but all the cancers I saw were in the advanced stage, from pain, inability to sleep at night, and eventually weight loss and deformation.

Esophageal cancer, my sister's husband's grandfather was more than 200 pounds before he got sick, and he lost 170 pounds five months after being diagnosed with esophageal cancer.

Gastric cancer. Stomach, liver, and pancreatic cancers can all cause loss of appetite. Colon cancer prevents the colon from absorbing food and nutrients, leading to weight loss. But weight loss isn't always a sign of cancer, and it can simply be due to loss of appetite, stress or depression.

Fat cancer.

Weight loss in cancer patients may be due to the following reasons:

1. Tumor growth consumes nutrients from the body. Because tumors need to consume a large amount of protein and other nutrients during the growth process, the amount of nutrients required by the human body is reduced, which is easy to cause the patient's body to be emaciated.

2. Loss of appetite. Because the disease will cause the patient to lose appetite, accompanied by fatigue, exercise tolerance and other symptoms, which will make the intake of protein and other nutrients with leakage insufficient, and then lead to the patient's body emaciation.

3. Lack of emotion. When a patient is diagnosed with cancer, emotional stress and other stupid causes will aggravate the poor diet, and eventually promote insufficient nutrient intake, which will make the patient more emaciated.

The weight of cancer patients has increased, which does not mean that the cancer is completely cured, but for cancer patients, especially advanced cancer patients, if the cancer lesions are reduced after **, the patient's weight can rise, which is a better phenomenon.

Many advanced cancer patients can obtain different degrees of control of the lesions after chemotherapy, radiotherapy, targeting, immunity and other anti-cancer**, the patient's quality of life can be improved, and the appetite can be improved. Cancer patients who have passed through ** may maintain the stability of the cancer base mold for a long time, and the patient can maintain a basically normal weight and life status at this time.

Analysis:

Generally, cancer is depleting to the human body at the time of arrival, and the more advanced the cancer, the more obvious the weight loss.

Guidance: If you lose weight rapidly in a short period of time, you should be alert to the possibility of cancer.

Not necessarily, but wasting is one of the manifestations of cancer, and it is recommended to go for a check-up if it declines too quickly.

Not necessarily, it's best to go to the hospital for a check-up.

Cancer patients usually lose weight or even lose weight because of loss of appetite or difficulty eating (due to tumors in the oral cavity or esophagus). Patients with advanced esophageal cancer will not eat water.

Most cancer patients have significant weight loss or weight loss, and some people develop cancer that is detected by significant weight loss. The main reason for the weight loss of cancer patients is that the consumption of nutrients is greater than the intake, and the body cannot make ends meet with the heat energy, which is the negative balance of heat in medicine. Because cancer cells consume a lot of nutrients during the multiplication process, and cancer cells mainly consume proteins in the body, which is completely different from the nutrients required for the metabolism of normal cells.

The protein consumed by cancer cells in the metabolic process can only be extracted from muscle protein, so the weight loss of cancer patients is manifested as muscle atrophy at the beginning, unlike the weight loss caused by other diseases, which starts with fat loss and then occurs in severe cases. Another reason for emaciation is that cancer cells can produce a large amount of toxins during the metabolism process, which can suppress the patient's appetite, resulting in loss of appetite, decreased food intake, and insufficient nutrient intake. In addition, when patients who have been diagnosed with cancer receive radiation treatment and crude therapy or chemical **, it often makes the patient lose appetite, anorexia, nausea, vomiting, and some patients will have psychological anorexia due to cancer, which will inevitably make cancer patients lose weight.

Wasting in cancer patients also has a great impact on the prognosis. A survey of more than 3,000 patients with various cancers found that those who lost weight survived half as long as those who remained at a normal weight.

According to statistics, the weight loss of lung cancer patients is not more than 7%, and the anti-cancer drugs are still effective, if the weight loss is more than 18%, the ** of anti-cancer drugs will not help, not to mention the reaction of emaciated people to the digestive tract cancer to receive chemical drugs**. Therefore, in the case of ** cancer, it is necessary to pay attention to the nutritional status of the patient. Recently.

National cancer institutes and doctors have included nutrition as an important part of improving methods and improving results.

Various methods of cancer, such as surgery, radiation, anti-cancer chemical drugs, are a serious blow to the patient. In order for patients to defeat cancer, endure the blows in **, and repair tissues damaged by cancer cells, they need more nutrients. Taking lung cancer as an example, in patients with a weight loss of more than 6%, the use of anticancer drugs plus nutrition** can make 50% of patients effective, and if only attention is paid to drugs** without nutrition**, only 20% of patients will be effective.

The American Cancer Society (ACS)'s "Nutrition and Exercise Guidelines for Cancer Prevention" first recommends maintaining a healthy weight throughout life, as follows:

1.On the premise of not having a low body weight, the thinner the better, and maintain it for life;

2.Avoid being overweight at any age. For people who are already obese or overweight, even a little weight loss can be good for the body and a good start to health.

3.Engaging in regular physical activity and limiting your intake of high-calorie foods and beverages are key to maintaining a healthy weight.
