Uremia is a syndrome caused primarily by the accumulation of urea and other ions in the blood, which are toxic substances produced by the liver during the digestion of proteins usually filtered by the kidneys. Normally, an excess of urea capable of causing uremia occurs when the kidneys suffer a deficiency due to the inability to filter blood as they should.
However, in healthy people, blood urea levels can also increase slightly due to a variety of factors, such as eating habits, physical inactivity, body hydration, and the way the body performs metabolism, which doesn’t necessarily mean kidney disease.
- Kidney failure is caused by injuries due to acute or chronic diseases affecting these organs.
- Such as high blood pressure.
- Diabetes.
- Dehydration.
- Severe infections.
- Strokes.
- Alcoholism and drug use.
Blood level considered normal
Blood level considered critical:
I know the best kidney failure, symptoms and treatments.
Excess urea is toxic to the body and affects circulation and various organs such as the brain, heart, muscles and lungs, so the symptoms of uremia are:
In addition to excess urea, kidney failure also causes a buildup of fluids and other electrolytes in the blood, such as sodium, potassium and magnesium, which can even worsen symptoms of uremia.
Diagnosis of uremia is made by the family doctor or nephrologist, by direct measurement of urea and indirect bleeding by ureic nitrogen, which is high; In addition, if blood tests are altered, uremia is also associated with the presence of kidney failure and the aforementioned symptoms. I understand better than this means the urea test.
Other blood tests, such as creatinine, sodium, potassium, magnesium, or orin, help detect changes in the kidneys and define a diagnosis of kidney failure.
Uremia treatment is done by hemodialysis, which has the ability to filter blood similarly to a normal kidney. Patients with renal impairment usually require 3 sessions of haemodialysis per week. As hemodialysis progresses.
In addition, it is important to maintain good habits to prevent worsening kidney failure, such as physical activity, drinking water recommended by the nephrologist and eating a balanced diet.
