January 21, 2021

So many people today experience problems with their kidneys, livers, and even their heart. One common organ that is usually being affected is the kidney. The kidneys play a very important role in our body. Any damage to our kidneys can be detrimental to our health. One common kidney problem is urea nitrogen high level. This is also known as uremia. This condition is actually very dangerous. Its symptoms are quite serious. And it really poses harm to the patient.

Literally, uremia means urine in the blood. But uremia is really when urea nitrogen is high. Urea is a waste product in our bodies. Usually, the kidneys carry urea away from our blood and dispose of it in our urine. But the level of your blood urea nitrogen is really high it could be a problem with the kidneys. So today we’ll be having a look at the causes, symptoms, and also treatment of uremia.

Symptoms Of  Urea Nitrogen High Level

A patient with uremia would present signs and symptoms that are quite similar to those of chronic kidney disease. This could mean that most people with kidney disease can develop uremia. And most times they do not know. It’s important that if you have kidney disease you would undergo regular checkups and blood tests. Also, urinalysis from time to time is also very important.

Symptoms among patients with uremia vary. But if you notice any of these symptoms you have to go see a doctor immediately. That’s because the kidney problem is life-threatening. Any further delay can be harmful.

  • Unexplainable weakness: People with kidney problems tend to get weak easily. They are easily exhausted. Even when they eat well and get enough rest it still doesn’t change. And over time the symptom would get really worse.
  • Neurological problems: this is another common symptom among patients with uremia. There could be nerve damage due to the problem with the kidney. That is why tingling and electrical sensations are felt in the body. Most often felt in the extremities of the body, your hands, and feet.
  • Loss of appetite: Most patients with high blood urea levels lack appetite. It’s usually associated with vomiting and also nausea. Because they lack appetite they tend to lose weight over a period of time. Also since there is vomiting, there is a lack of electrolytes in their body.
  • Frequent urination: You would expect that the urine production would decrease but no. The kidneys after some time would try so hard in removing the waste products. When this happens there is an increased amount in the production of urine.
  • Metabolic acidosis: Patients with uremia usually show signs of metabolic acidosis. This is when the body makes too much. And one of the causes of this is a kidney problem.
  • Dry, itchy skin
  • High blood pressure
  • Swelling of the feet and ankles

Causes and Risk factors of Urea Nitrogen High Level

One common cause of uremia is chronic kidney disease. In chronic kidney disease, it becomes difficult for the kidney to filter out waste. With that, the levels of urea in the blood would be high.

There are also several conditions that could lead to chronic kidney disease. The two most common are diabetes and high blood pressure.

With diabetes, there’s an increased amount of blood glucose. With this, there can be damage to the kidneys and blood vessels in the body. While high blood pressure has an effect on the blood vessels of the kidneys. It usually makes it weak or hard.

Here are other causes of kidney diseases that could lead to uremia.

  • Kidney infections or urinary tract infections
  • Glomerulonephritis
  • Autoimmune diseases such as lupus erythematosus
  • Genetic kidney diseases
  • Problems with the kidney structure and shape
  • Blockages around the kidney


So these are some causes of kidney diseases that could lead to uremia. There are also risk factors that could increase the chances of a person having uremia. They are:


Also, older adults are more prone to kidney failure than younger ones. Also, some races are at higher risks. Such as African-Americans, Asian-Americans, Hispanic Americans and Pacific Islanders.
At the same time, people with kidney disease that do not undergo dialysis are at higher risk of having uremia.



Once you notice the symptoms listed above then you have to see a doctor as soon as possible. That’s because uremia is a dangerous health condition. In fact, it’s a medical emergency that must be attended to immediately. Also, you would have to be hospitalized. Because it’s not something that can be treated in the comfort of your bedroom.

The treatment of uremia is dependent on the cause. Your doctor would first try to find out the cause of your uremia. Once your doctor knows then he can proffer a treatment option. For instance, if it’s a result of blockage then surgery is needed. If it’s a result of high blood pressure then medication is needed.

Most people that have uremia would need to undergo dialysis. In dialysis, a machine is used. This machine acts as an artificial kidney. And it helps remove any form of waste in the body. At the same time, some people might need to get a kidney transplant. This is where it gets harder.

Some people would have to wait for so many years before they can get a donor. And if they do it would have to be a good match. But before they get one the doctor would advise that the patient should undergo dialysis while waiting to get a donor.

There’s research going on about regenerative medicine. This medicine is a treatment method that could help those with uremia and kidney disease later in the future. This medicine would help the organ heal itself. It sounds pretty cool. But they are still doing research on it.

Kidney problems are not conditions you should take with levity. Especially when you have problems like uremia. This is why when you see any symptoms go consult a doctor. The doctor would be able to order for tests. These tests would be able to show if you really have your urea nitrogen high.
