Blood in our bodies is an important fluid that runs through our heart, arteries, capillaries, and veins, carrying oxygen and all the necessary nutrients to the cells in our body. Along with it, blood also carries the wastes produced by metabolism, the most crucial of which is the carbon dioxide, from the tissues to the organs, from where these wastes are expelled from the body. It is why many of us often worry about how to reduce blood urea?

But aging and often mainly because of increased consumption of dietary proteins results in increased urea production in our body. This increased production of urea may cause plasma/serum urea in our blood to rise.

This area is a waste product produced due to the breakdown of proteins by the liver. It carries through our blood, is filtered out by our kidneys, and is removed from the body through urination. But, if your liver isn’t healthy, the proteins may not get broken down the way they should be by the liver. And, if your kidneys aren’t healthy, the same may not get properly filtered out. Either of the two could lead to changes in the amount of blood urea in the body, resulting in certain health problems like:

  • Frequent need to urinate
  • Pain in the joints and bone
  • Muscle cramps
  • Restless legs while sleeping
  • Itchiness
  • Fatigue, and
  • Swelling in the arms and legs
  • Loss of appetite

Why are high blood urea levels bad?

Elevated levels of urea in your blood could have some adverse health impacts. A high concentration of blood urea may lead to oxidative stress in the cells. High blood urea also indicates increased protein breakdown, which can further be associated with decreased immune functioning. Studies indicated that high blood urea levels also indicate increased risks of infections.

High blood urea levels have also been associated with an increased risk of strokes during heart surgeries, and many adverse outcomes in patients with heart failures and other heart problems. Blood urea can even lead to decreased renal functions and other kidney functionalities.

How to reduce blood urea?

First and foremost, you must seek medical assistance if you have the above-mentioned symptoms to find out the underlying cause of your high blood urea levels. You may be advised by your doctor to undergo certain medical tests to determine the range of your blood urea for better diagnosis and treatment.

A diet low in proteins is less strenuous on our kidneys. Therefore, such a diet is always the best bet for people with kidney issues. When we eat protein, our body produces a compound called urea. If our kidneys are damaged or are not functioning properly, the urea stars building up in our blood and can cause continuous fatigue and loss of appetite.

People with high blood urea levels and kidney problems will have to follow a low-protein diet for a long. Such kind of diet restricts the intake of high-protein foods and focuses on eating plenty of fresh vegetables, fruits, and healthy fats. People not suffering from kidney issues or high blood urea are generally not recommended such diets, as it may also lead to nutrition deficiency and many other health issues. Always seek the advice of an expert dietician and healthcare professional before you opt for such a diet plan.
