Symptoms of Blood Urea


Blood urea occurs when the kidneys have trouble reabsorbing the urea, which is a waste product from the liver, from the rest of the body. It ends up in the blood in abnormal levels. It can be life threatening and cause serious issues throughout the body. Knowing the symptoms of blood urea can greatly increase the chance of catching this malady before it causes irreversible damage.

Kidney Trouble

Experiencing pain in your lower back can mean you’re having trouble with your kidneys, which is directly related to having high levels of urea in the blood. It can be anywhere from a dull ache to a throbbing sensation to more sharp pains. If undetected, kidney failure will eventually occur. Since kidneys are an area associated with urine and cleansing processes, it is a tell-tale place to begin looking for blood urea symptoms. This can also include pain when urinating.

Fatigue, extreme exhaustion for no apparent reason, weakness without exertion, an overall weariness and low energy levels can occur when the blood urea levels are too high. If you realize you are more tired than usual or seem to be exhausted with no reason, this could very well be a sign of blood urea. Fatigue is also a sign of other health issues and should be taken seriously.

When a high level of blood urea nitrogen is present, a considerable amount of dehydration will be occurring as well. If you find you are thirsty at all times, no matter what you drink, and your skin is flushed and pinkish in color, you may be experiencing dehydration. Your mouth will be continuously dry, and a loss of appetite may also occur in severe cases. Dehydration is a symptom of many serious maladies; if it appears that you are or have been experiencing it for some time, contact your doctor immediately.

Hypotension or low blood pressure is a symptom of urea in the blood. While most often, low blood pressure is a good thing to have, when it is too low it is harmful. Very low blood pressure cannot help the body to deliver adequate amounts of blood throughout the body to perform its regular activities. Having urea in the blood causes the bodies blood pressure to drop to lower than adequate levels.

Oral Issues

Because of the urea, which is a waste, coursing through the body, strange symptoms can occur. One of the more odd symptoms is an ammonia-like taste in your mouth as well as a strong odor of bad breath. It can be almost like ammonia fumes and quite strong. You may also experience mouth sores and small abrasions inside the mouth that are tender and painful. They will not heal, but get incrementally worse.
