The function of kidney is filtration and reabsorption. When kidney disease occurs, it can't be filtered and reabsorbed, which will lead to the loss of nutrients, such as proteinuria, which is the loss of protein. When protein is found in urine, protein can't be found under normal circumstances, but when there is a problem with renal function, he can't filter out the nutrients and re-absorb them, but completely eliminate them. At this time, there are a lot of various nutrients in the urine.
Not only in protein, there are various nutrients in urine, so the urine is not clear at this time. Because of nutrition, it is equivalent to oil leakage in the car and battery leakage, which will soon be consumed by itself. It is these nutrients that do not participate in the activities of human cells and tissues, but are directly lost, so that people will lose weight under normal diet and incremental diet, because there is a big gap, which cannot be re-absorbed and effectively filtered.
Patients with nephritis need to properly limit the intake of salt and high-protein food in their diet, which will lead to loss of appetite, so they may lose weight. There are also some patients who have suffered from nephritis, because of their wrong understanding of nephritis, and they have a strong psychological pressure, which leads to patients' unwillingness to eat, pessimism and world-weariness, and also makes them lose weight. Therefore, patients with nephritis must pay attention to the adjustment of diet structure, and at the same time carry out psychological counseling, such as patients to establish confidence in overcoming the disease.
At this time, these harmful substances that can't be effectively filtered will rise, and at the same time, they can't be reabsorbed, leading to the decline and loss of nutrients, and people will become thin, so they will develop in two bad directions. First, toxins will not be filtered out, and second, nutrients will be lost, and people will be weak and emaciated, but toxins in the body will continue to rise, which will eventually lead to these serious consequences of uremic ketoacidosis and failure. Thorough treatment means separating toxic and harmful substances.
