1. Hunger: When people are hungry, they can't get enough nutrition from food, including protein. Due to the lack of protein, the body cannot synthesize enough amino acids, resulting in negative nitrogen balance. Digestive system diseases: Some digestive system diseases, such as intestinal inflammation, pancreatitis and hepatitis, may lead to impaired digestion and absorption.
2. Malignant tumor: Some malignant tumors, such as pancreatic cancer and colon cancer, may secrete some hormones or metabolites, which will affect the body's absorption and utilization of nutrients. These tumors usually cause the body to consume more energy and nutrition, which leads to negative nitrogen balance.
3. Malnutrition: Long-term malnutrition or unbalanced diet may lead to the lack of essential amino acids in the body, which may lead to negative nitrogen balance. This situation is usually similar to hunger, but it may also occur without obvious symptoms of hunger. Metabolic diseases: Some metabolic diseases, such as diabetes and thyroid diseases, may affect the utilization and storage of energy and nutrients.
Negative nitrogen balance analysis
1, negative nitrogen balance means that protein metabolism in the body is in a state of consumption, and net nitrogen excretion is greater than intake, that is, nitrogen cannot make ends meet. When the nitrogen balance is negative, because the total amount of nitrogen-containing substances in the body decreases, the nitrogen-containing substances needed by the human body have to be obtained from the external environment. Negative nitrogen balance may cause a series of health problems.
2. Abnormal metabolism of protein in the body will affect the normal physiological function of the body, which may lead to fatigue, emaciation, decreased resistance and other problems. In addition, negative nitrogen balance may increase the risk of infectious diseases, because the human body needs to use its own reserves of protein to maintain life activities, and these reserves of protein could have been used for the construction and defense of the immune system.
3. Negative nitrogen balance may also have a negative impact on growth and development. For children, it is in a critical period of growth and development. If there is a negative nitrogen balance, it may affect the development of their bones, muscles and nerves. Negative nitrogen balance may also increase the risk of cancer.
