A certain amount of urine that is excreted from the body in 24 hours is called daily diuresis. It is this value that is an important parameter of the course of pregnancy. Due to the increasing need for fluid, the frequency of urination should increase.
In a healthy pregnant woman, the amount of fluid that has entered the body should be completely excreted - its delay affects both the health of the expectant mother and the development of the baby
Any deviation from normal values characterizes the presence of a violation of renal function in a woman. That is why practicing obstetrician-gynecologists pay special attention to the amount of urine excreted per day. Early diagnosis and timely treatment will help to avoid possible complications.
What does a daily urine test show?
The calculation of diuresis is carried out according to the following algorithm - about 80% of the fluid is excreted from the female body with urine, the remaining 20% is excreted by the sweat glands.
The daily rate is calculated taking into account the increased fluid intake of a pregnant woman and the increase in the frequency of urine discharge within 24 hours. An indicator of 1.5 to 2 liters is considered normal.
Deviations from the norm are not observed if the expectant mother does not have any chronic diseases of the endocrine organs and urinary system, as well as complications during pregnancy.
The change in the value of daily diuresis is influenced by such a pathological condition as preeclampsia (late toxicosis), which is characterized by:
• persistent deterioration of the woman's general well-being;
• nausea and vomiting;
• persistent arterial hypertension;
• the presence of edema on the limbs;
• excessive weight gain;
• convulsions;
• proteinuria (removal of protein from the body in the urine).
Proteinuria is a dangerous symptom that indicates kidney damage, in order to identify the pathological process, it is necessary to conduct a biochemical analysis, constantly monitor blood pressure and diuresis
There are the following types of violations of daily urine output:
1. An increase in the volume of excreted biological fluid up to 3.5 liters - polyuria. Most often, this phenomenon is observed with a persistent increase in blood pressure, diseases of the endocrine system.
2. A significant decrease in the amount of urine - oliguria. This pathological condition develops with dehydration of the female body with frequent vomiting or diarrhea, inflammation of the renal parenchyma, hemolytic anemia, blockage of the lumen of blood vessels (embolism).
3. Lack of urination - anuria, which indicates the development of serious pathologies in the female body.
The causes of these conditions are both physiological and pathological factors. Any changes in daily diuresis cause expectant mothers to worry. However, do not panic - first of all, you need to consult with an experienced specialist and undergo a comprehensive examination.
