Hello, everyone, many people are very thin. When they go to the hospital for examination, they find that they have cancer. So why do they get thinner after getting cancer? Today we will discuss this problem.

First, the causes of weight loss in cancer patients can be divided into two categories. The first category is the consumption caused by cancer itself. The first small aspect is that cancer cells consume a lot, and the metabolic rate of cancer cells is much higher than that of our normal cells. Then cancer cells consume a lot of energy, which leads to the energy intake of our normal tissues and is consumed by a large number of cancer cells. In this way, our collective intake is insufficient, which leads to our sudden loss of weight.

Second, cancer cells lead to the production of toxins, because cancer cells grow particularly fast, blood function is easy to be short, leading to local cancer tissue necrosis. Then produce toxins, which will lead to our fever, loss of appetite and so on. , will affect the intake of nutrients. Then a fever will consume the body's energy. At this time, it will cause sudden thinning.

Third, cancer-related complications lead to obesity. Tumors in the digestive tract will reduce food intake, and tumors in the digestive tract will block the digestive tract, which will lead to difficulties in eating in the future and lead to obesity. Pain affects appetite, and some cancers can cause intractable pain in patients, which in turn leads to decreased appetite and sudden weight loss.

Fourth, some patients need chemotherapy, so chemotherapy has some side effects, such as nausea, vomiting, diarrhea and other complications, which not only reduces our food intake, but also affects our nutrition and eventually leads to obesity. Psychological burden affects appetite. Some patients know that they have cancer, and their psychological burden is particularly heavy. In the future, they will lose their appetite and suddenly lose weight. So it is a very common phenomenon for cancer patients to lose weight. Because of sudden weight loss and low resistance, it will affect the treatment effect of patients.

Therefore, nutritional support is very important in the treatment of cancer patients. Well, to sum up the content of this lesson, there are two main reasons for the weight loss of cancer patients, one is the high consumption of cancer itself, and the other is the complications caused by cancer. All right, we're done here. Thank you for watching. Goodbye.
