Ever seen “BUN” on a blood test report and wondered what it means? It stands for Blood Urea Nitrogen, and it is a key indicator of how your kidneys function. So, what happens if my blood urea nitrogen (BUN) is high?
BUN measures the amount of urea nitrogen in your blood. Your liver makes urea after the breakdown of proteins, as covered by researchers at the University of Rochester. Your kidneys normally filter this out, but elevated levels can signal a problem.
Understanding High BUN Levels
Normal BUN levels usually range from 6 to 24 mg/dL. However, levels can fluctuate, and there is not a one-size-fits-all “normal range.” The normal bun level deemed standard can change because of many reasons.
Things that cause high levels:
- Dehydration
- High-protein diets
- Certain medications.
If your BUN is consistently high, further testing by your healthcare provider could be smart. A blood urea nitrogen test helps to see what is happening.
Going Deeper Into The Causes
Several things can cause elevated BUN levels. A common reason could be simply not drinking enough water. When you’re dehydrated, your kidneys can’t remove waste products efficiently.
Diets heavy in protein also put more load on your kidneys. Certain drugs, like some antibiotics, can mess with your BUN test results.
The Mayo Clinic has additional details on what medications can alter a BUN test.
What Happens If My Blood Urea Nitrogen (BUN) Is High?
The early signs of kidney problems are usually subtle. However, persistent high BUN values is one warning sign that things aren’t working right. Severe kidney problems are also indicated if you also have a creatinine blood test coming back high.
When your kidneys get bad, waste builds up. You may see several potential issues that need checking out. These potential conditions could be related.
- High blood pressure
- Anemia
- Heart disease.
Kidney problems need diagnosis. If not diagnosed, things will most likely get worse. Getting it caught early is often the best way to keep a small problem, small.
Symptoms and Other Issues
Early on, most people experience no obvious issues. Some problems only become apparent later. Regular testing becomes even more crucial to manage and improve your outcome.
Later-stage kidney problems often show up with certain warning signals, according to kidneyfund.org. Here’s what to be aware of, according to medlineplus.gov:
- Changes in how often you pee.
- Feeling fatigued.
- Swelling in your arms, legs, or feet.
- Muscle cramps.
- Trouble sleeping.
If you notice any of these, talk to your doctor to evaluate things.
Interpreting Your BUN Test Results
What does your BUN value truly mean? While standard ranges provide some indication, normal bun levels can vary.
Factors such as age, sex, and even your hydration status could shift levels. This makes getting personalized guidance very beneficial to your outcome. Work with your provider, especially if you have diabetes or have kidney problems running in your family.
Remember that seeing a bun test result that may vary from standard levels doesn’t automatically signify a major issue. So, this is where an expert will give insights to be clear on where you stand. A blood urea nitrogen test measures many things.
The BUN-to-Creatinine Ratio
Another useful thing to evaluate is your BUN-to-creatinine ratio. Providers sometimes check this, especially to see how well the kidney works. A high ratio suggests dehydration, while a low ratio might indicate liver disease.
Creatinine is another waste filtered by the kidneys. The Cleveland Clinic details more about the connection, found here.
When your creatinine levels remain in balance, then generally things look fine. It provides a fuller assessment of your situation.
Addressing High BUN Levels: What Comes Next
If your levels remain persistently elevated, see a doctor to decide the next steps. Do you understand what happens with routine changes in habits?
Your provider will investigate to pinpoint if an underlying problem exists. This step allows you to find the reason behind the high bun level.
Tests like serum creatinine will likely occur. Checking the estimated glomerular filtration rate (eGFR) could be needed as well.
Below is some useful data of different ways to look at potential kidney issues:
| Test | Purpose | What it Measures |
| Serum Creatinine | Assesses kidney function | Creatinine buildup |
| eGFR | Estimates kidney filtration rate | How well kidneys clean blood |
| BUN | Measures urea nitrogen | Urea nitrogen levels in blood |
Getting things fully evaluated helps guide management going forward. If the readings appear high for the kidney related areas, action may need to be taken soon.
Managing Kidney Problems and Treatment Plans
Once you get the assessment, a provider might prescribe treatments. This includes medications and changing things like activity levels and eating habits.
It is beneficial to get more active each day. Doing things such as walking more. Even small steps will help improve your overall body functions.
The goal remains managing issues early before they get more severe. Catching things in the earlier stages can make a huge difference over time. A nitrogen test, also known as BUN, can catch it early.
Lifestyle Factors and Your BUN
Making lifestyle changes can potentially influence BUN readings over time. If you start monitoring some health areas regularly, this can be hugely positive. Certain factors contribute significantly when your BUN level becomes too high.
Some steps people may try if you start monitoring various factors of health.
- Drinking adequate fluids.
- Limiting protein intake
- Managing stress levels.
Getting into better overall health and body composition allows kidneys to perform their jobs with a lot less problems. Also, review the lessons of what happens with investing in downturns. This makes it apparent that addressing the real issue, not ignoring, could possibly improve overall things.
Practical Steps Toward Improvement
Getting enough fluids should become routine practice. Reduce the loads put on kidney functions. Cut back on things like red meat, dairy and processed products high in sodium, like processed meats and some meals.
Look to bring down cortisol. This may involve walking more, yoga or other exercises you like to do. Reducing cortisol tends to result in many health benefits, per reports shared on ncbi.nlm.nih.gov.

Ultimately, living healthy, supports healthy organ function to promote improvements over the long run. Making better nutrition, activity and testing regular, makes you prepared.
FAQs about What happens if my blood urea nitrogen (BUN) is high
Should I be worried if my BUN level is high?
A high BUN level could indicate that your kidneys are not functioning as they should. But it is not an automatic cause for worry. Other factors like dehydration and a high-protein diet also elevates your levels.
More tests could possibly help evaluate why levels were off. This should reduce your uncertainty.
What is the treatment for a high BUN?
Treatment depends on the underlying problem, if there even is an underlying problem. Often making small daily steps helps. For example, better hydration, changing diet to lower protein intake, and medication adjustment sometimes prove sufficient.
These steps are very common when reviewing the bun test results.
What is the treatment for high urea nitrogen?
Managing high urea nitrogen is a multi-layered path of figuring things out. You want to make lifestyle adjustments along with possible medical therapies. You first need to find the specific root cause through thorough check-up from your healthcare team.
What are three things that could cause high levels of urea in your blood?
Three common reasons for high blood urea include poor kidney function, dehydration, and a high-protein diet. Keep in mind there could also be various other causes as well, especially with people with chronic conditions. So be certain to get thorough tests to pinpoint with a common blood test.
Conclusion
Regularly assessing BUN shows valuable insights to allow managing health conditions. If you ask, “What happens if my blood urea nitrogen (BUN) is high?”, well know that consistently elevated BUN levels frequently suggest potential kidney trouble. Also other health issues contribute like eating plans or insufficient fluids.
When things get noticed soon enough, providers help craft strategies like medication, supplements, diet or fitness that gets issues more controlled before any further potential problems. Understanding BUN empowers your self-care approach for the long term, with peace of mind along the way.
