Recommended precautions on how to prevent further progression

Detailed Answer:
Hello and welcome at "Ask a Doctor" service,

High BUN levels may be caused by different causes with kidney disease being the most common. It is important to treat the cause of increased BUN. For instance, if heart failure is the cause, this needs to be treated first. It is good you are keeping yourself hydrated as dehydration is another possible cause.

As for high BUN due to kidney disease, the main things to consider is the diet and also the medications.

If you use certain medications, it is important to consult them with your doctor as some of them may worsen the kidney function. Even over the counter drugs like Ibuprofen may cause this.

As for the diet, you need a diet not too high in salt and in proteins.
- it is recommended to eat plenty of fruit and vegetables but avoid food high in protein. Even the vegetables, it is best to be fresh and not canned as these often have extra salt.
- protein is contained in meat, seafood, and some plants (beans, nuts, etc). You may have some of these food but frequent small amounts so they do not overload the kidneys.
When a patient has kidney failure it is advisable to be closely followed by a nephrologist and a dietician that will work together to optimize his treatment.

I hope this is helpful and answers your query. I remain at your disposition in case further assistance is needed.

Kind regards,
Dr. Antoneta Zotaj, General and Family Physician
