When uremia or azotemia plagues someone, it indicates that the kidneys are not operating the way they should. Uraemia refers to urine in the blood. The kidneys are supposed to expel nitrogenous waste produced a result of protein and amino acid metabolism. When a systematic or local infection impacts kidney function in the body, this condition indicates end-stage kidney failure or very acute kidney failure.

This condition is when the kidneys fail. Some of these disease symptoms include shallow respiration, decreased energy, diminished exercise tolerance, lack of interest in daily life, whole body swelling due to fluid retention, nausea, and vomiting. Azotemia, on the other hand, refers to nitrogen in the blood. It can be considered as the chemical stage of kidney failure.

In this condition, the patient does not display any concrete symptoms. Protein and amino acid break down, resulting in the development of nitrogenous materials that must be removed through the urine. When kidney function is compromised, the waste is not adequately cleaned out of the body. These waste products end up getting into the blood. When BUN and serum creatine levels are elevated by around 20 to 30 percent, and the glomerular filtration rate goes below 70 ml/min, the condition indicates azotemia.

Kidneys are very important organs in the body; they play important roles like the production of hormones, fluid balance, electrolytes, regulate blood pressure, production of urine. When a person has uremia or azotemia, it indicates that the person is not functioning well. The kidney can be damaged by unhabitual eating, lack of exercise, and others.

Uremia means urine in the blood; the kidney excretes all nitrogenous waste formed as a result of protein and amino acid metabolism. Urea and uric acid are formed as a result of protein breaks down, are filtered through the kidney, and extracted as urine.

If the patient suffering from uremia is not hospitalized quickly, it can lead to organ failure and, eventually, death.

Azotemia is defined when there is nitrogen in the blood; when a patient has azotemia, the patient does not show any overt symptoms of kidney disease.

There are three types of azotemia, which include prerenal azotemia, when the blood flow to the kidneys is comprised, intrarenal azotemia occurs due to a primary kidney disease like acute kidney failure, and post renal azotemia occurs due to the obstruction of ureters.
