Kidney disease patients, especially those with renal failure, are often accompanied by nausea, vomiting, and even gastrointestinal bleeding. Why do patients have such symptoms?
Many diseases are more and more serious, especially some patients with renal insufficiency early on their body slightly abnormal symptoms are too ignored, when they appear serious nausea, vomiting and other obvious symptoms before going to see a doctor. At that time, the disease may have developed into uremia, so nausea, vomiting and other symptoms need to be taken into account.
These symptoms are generally associated with protein loss, metabolic acidosis, ion disorder, renal failure, and the causes of the symptoms vary from time to time:
Early kidney disease, due to a large number of lost protein, the formation of hypoproteinemia, not only the limb edema, gastrointestinal tract also showed edema, so that gastrointestinal dysfunction, manifested as nausea. Vomiting. Always nausea and vomiting is a sign that the patient's condition is worsening; Loss of appetite, nausea, vomiting is a major clinical symptoms of kidney disease, many patients with renal dysfunction such symptoms, the general physician is only symptomatic treatment. Although this treatment can alleviate complications, it can not prevent renal pathological damage and renal fibrosis.
During the development of renal failure, the excretion function of the kidney is obviously reduced, and the toxic substances such as urea nitrogen, guanidine, phenols, indoles, creatinine and uric acid are produced in the body, with the increase or accumulation of these toxic substances in the blood. Will cause nausea, vomiting and other gastrointestinal irritation symptoms, uremia patients significantly increased gastric acid secretion, a variety of gastrointestinal peptide hormones between the occurrence of disproportionate changes leading to the destruction of physiological balance in the body. The weakening of self-regulation results in abnormal gastrointestinal motility.
In uremia period, due to the changes of substance metabolism, bacteria parasitic in the gastrointestinal tract can produce urease, this enzyme can make the synthetic urine decompose ammonia, and ammonia has a strong irritation to the gastrointestinal tract. It can even cause "uremic ulcers," which can cause nausea, vomiting, loss of appetite, and even bleeding ulcers. In addition, if dialysis dehydration is too fast, dehydration is excessive, more than 5% of dry weight. As a result, the volume of plasma drops rapidly in a short period of time and exceeds the tolerance level. Patients also present with reduced blood pressure, nausea and vomiting.
No matter in which period the symptoms such as nausea and vomiting should be effectively taken to delay and control the progress of the disease. Kidney is an important organ of the human body kidney fibrosis indicates that kidney injury is more serious. Severe conditions can lead to complications, as well as digestive tract, respiratory and blood systems.
