Dehydration on High BUN Level

Dehydration on High BUN LevelBlood urea nitrogen (BUN), together with creatinine, is usually taken as an indicator of kidney function. If the BUN level is higher than normal range, it may mean that your kidney is not working well. Heart failure, dehydration, or a diet high in protein can make your BUN level higher. This article is to give you an overview of dehydration on high BUN level.

What is blood urea nitrogen?

Urea nitrogen is what forms when protein breaks down. It is carried in your blood, filtered out by your kidneys, and removed from your body in your urine. The amount of urea nitrogen in the blood is tested to check your kidneys to see whether it is healthy.

What is dehydration?

Dehydration occurs when your body loses more fluid than you take in. With dehydration, more water is moving out of our cells and bodies than what we take in through drinking. Diarrhea, vomiting, excessive sweating or fever can cause dehydration.

Why dehydration results in high BUN level?

As stated above, when dehydration occurs, the water or fluids in your cells begins to lose, which may lead to hypovolemia (decreased blood volume). That condition will cause hypoperfusion, and thus reduce urination. At this time, excessive blood urea nitrogen cannot be filtered through kidneys, so its level becomes high. Therefore, by increasing urine amount, the BUN level generally declines.

How to manage dehydration?

1. Eating hydrating foods, such as fresh fruits and vegetables. Remember to drink extra water, if you are eating dry or salty foods.

2. Taking a rest. This will prevent any more exertion, and help prevent fainting.

3. Applying cool, wet cloths to such areas as wrists, neck and face, collarbone, upper arms or inner thighs.

4. Giving water and juice in small amounts.

5. Seeking medical help, if someone is dehydrated from heat stroke or blood loss, or if dehydration is severe.

6. Getting medical help. If you do not know what have caused a severe dehydration, you should contact with the doctor immediately or take the patient to the hospital.

7. Improve the kidney function. Since healthy kidneys are responsible for the discharge or excessive urea nitrogen, improving kidney function becomes very necessary.
