Uremia is a terminal stage of many kidney diseases. In the early stages of uremia, symptoms such as nausea and vomiting related to the gastrointestinal tract often appear. Other symptoms can include itchy skin and a dull complexion. For women, complications such as menstrual disorders and irregular menstruation may occur. In such cases, it is necessary to go to the hospital to check kidney function and determine the specific levels of creatinine and urea. If creatinine exceeds 700, it generally reaches the level of uremia, requiring renal replacement therapy such as hemodialysis or peritoneal dialysis. For uremia, it is most important to control the intake of salt and water in the diet, avoid high-salt food, and also avoid drinking too much water to prevent fluid retention in the body, thereby endangering life, as this can lead to heart failure or severe edema.
