Urea is the product of the metabolic process of proteins; it originates in the liver and is almost eliminated by the kidneys; it is also a way to determine that our kidneys are working correctly. The breakdown of proteins during digestion is classified into amino acids that contain nitrogen and are released to produce energy in tissues and cells. The average urea values are between 3 and 7.5 mmol / L in men and 2.5 and 7 mmol / L in women. The causes of low urea can be diverse and range from overhydration to liver ailments; in the same way, it is necessary to perform periodic blood tests so that it can be diagnosed in time and no further damage to health occurs. At FastlyHealwe, explain the causes of low urea.

Low protein diet

Proteins are made up of amino acids, which have an essential function in our body. These nutrients are constantly being formed and need to cycle to ensure our body’s balance; Through digestion, proteins are broken down into amino acids to be absorbed and used throughout the day.

High protein foods come from animal sources such as meat, fish, eggs, cheese, and yogurt. Low protein intake is one cause of low urea, and people on a vegetarian diet are most likely to be most affected.


Perhaps you have always heard that you must keep your body hydrated to ensure its proper functioning. However, overhydration or hyperhydration signifies that excesses are not good, even if they are nutritional elements. This syndrome appears when more water is consumed than our body can eliminate; if you are a healthy person, your body can receive up to 7.5 liters of water per day, if these values ​​are exceeded, sodium begins to dissolve in the blood, causing the diuretic hormone stops being produced, and the absorption of water molecules becomes uncontrolled.

Liver diseases

This is another cause of low urea. However, it is necessary to clarify that this value is not the most important when it comes to diseases that affect the liver. Some of these diseases are:

  • Malnutrition is a state in which there is a deficiency in the assimilation of food caused by a poor diet or poor absorption pathologies.
  • Hepatic failure can occur due to decreased protein production or other pathologies such as autoimmune diseases, hepatitis B, and C.
  • Hepatic necrosis is a rare form of hepatitis that progresses very quickly and will require a liver transplant as a treatment.

Usually, the value of urea in the diseases that occur is associated; it is not isolated. If there is a disease associated with that value, it is necessary to verify other components that rule out the conditions described above

When there is a decreased urea value, if the person is healthy and there is no evidence of another disease, there is no reason to be alarmed. When it is associated with an illness, other more important values denote that there is a problem.
