Generally speaking, holding urine does not lead to uremia, but if the bladder is overfilled, it can result in an inability to urinate. This can lead to acute renal dysfunction. After catheterization, the indicators of renal function can quickly return to normal. Therefore, we should try to avoid holding urine as much as possible and go to the bathroom promptly when we need to. This is something we should pay attention to in our daily lives.

Causes of Uremia

Uremia is a syndrome caused by the progressive development of various chronic kidney diseases that ultimately leads to bilateral renal failure in patients, unable to timely remove excess water, electrolytes, and various toxins from the body. The causes of uremia are many and complex. Common causes include chronic nephritis, diabetic nephropathy, and hypertensive nephropathy. Other diseases such as chronic interstitial nephritis, chronic pyelonephritis, uric acid nephropathy, chronic obstructive nephropathy, renal vascular diseases, and hereditary nephritis can also lead to uremia. Once uremia occurs, patients often exhibit symptoms of general discomfort and may need to choose dialysis treatment, which can be either hemodialysis or peritoneal dialysis, depending on individual circumstances.

Does uremia transmit to others?

Uremia is not contagious to others because it is not an infectious disease. Uremia is a severe renal failure, so patients with uremia can interact, communicate, live, work, and study with healthy people without the need for gastrointestinal or respiratory isolation. Normally, if a patient with uremia is stable, they can engage in sexual activities and the disease will not be transmitted through sexual contact. Uremia usually presents symptoms such as nausea, vomiting, edema, and increased blood pressure. Therefore, patients with uremia need to undergo dialysis treatment. They can choose either hemodialysis or peritoneal dialysis. Dialysis treatment can significantly improve the symptoms of uremia and enhance the quality of life of the patients.

The precursors of uremia

The so-called uremia refers to the end result of chronic kidney disease causing long-term damage to the kidneys in patients. Patients with uremia often have long-standing conditions, as it takes time to progress from mild kidney failure to uremia. Before the onset of uremia, patients may experience symptoms related to kidney failure, such as swelling of the limbs and face, reduced urine output, proteinuria which leads to foamy urine, and visible blood in the urine due to hematuria. Patients are also prone to developing high blood pressure. These symptoms can be precursors to uremia, although other diseases can also cause similar symptoms.

What should I do about uremia heart failure?

Patients with uremia often develop complications of heart failure, which is actually the leading cause of death in patients with uremia. This type of heart failure is mainly due to the decreased ability of the kidneys to excrete water, leading to an increase in blood volume and an increased burden on the heart. It is also related to many factors such as the patient often having hypertension, anemia, coronary heart disease, etc. For such diseases, it is first necessary to assess whether the patient has excess water in the body. If there is too much water, urgent dialysis ultrafiltration is needed to remove the water. After the water is removed, the symptoms of heart failure will be significantly relieved. Secondly, it is necessary to deal with some other complications related to heart failure. For example, in the case of anemia, temporary blood transfusions or the use of erythropoiesis-stimulating agents to promote hematopoiesis can be used. Hypertension requires the use of antihypertensive drugs to control blood pressure and other comprehensive treatment measures. (Please use medications under the guidance of a doctor)

Is high creatinine uremia?

High creatinine levels do not necessarily indicate uremia. High creatinine often implies that the patient is experiencing renal failure, which can be classified into acute renal failure and chronic renal failure based on factors such as the patient's medical history and course of the disease. Uremia is the final state of chronic renal failure. Thus, even if high creatinine levels suggest the possibility of chronic renal failure, it does not necessarily mean that the patient has reached the final stage. Uremia, also known as end-stage renal disease, generally requires a patient's blood creatinine to exceed 707 µmol/L. Additionally, patients often simultaneously present with clinical manifestations such as renal anemia, disorders of calcium and phosphorus metabolism, and reduction in kidney size.
