Pregnancy is a time of many changes in the woman's body. The breasts grow, the belly increases, the vaginal discharge varies and, sometimes, even the color of the urine can change. Precisely on this last point a lot of doubts arise.Is the urine of pregnant women different as the gestation progresses? What colors can be given and what does each of them say? We solve all your doubts!
The urine of the pregnant woman changes throughout the nine months of gestation because it increases up to 75% more renal blood flow. This increase usually occurs from the second trimester (at week 16 of pregnancy) and usually lasts until the beginning of the third trimester (week 34), which decreases to 45%.
Furthermore, in this period of a woman's life, kidney filtration is 50% higher than before pregnancy, therefore parameters such as creatitinine, uric acid and urea will decrease considerably. And it is that hypertensive states can modify the parameters in the urine, increasing uric acid and the elimination of proteins in the urine.
In 80% of pregnant women, there is a certain degree of dilation of the renal pelvis and ureters, especially on the right side, and this can lead to the woman having nocturia (urinating several times at night) and frequency (increased urination). urination).
The nocturia It is very common since during the day the pregnant woman usually retains fluids, water and sodium in the form of edema in the lower extremities, that is, in the legs. Luckily (no need to worry or put your hands on your head), this liquid will be reabsorbed during night sleep, hence the excess is eliminated in the urine and increases 'trips to the bathroom'.
For its part, frequency It is produced by the increase in intravesical pressure and by the compressive effects of the uterus on the bladder, which you will notice more in the third trimester. It is important to clarify that all these changes usually disappear during the postpartum period.
It could be said that the normal color of the urine of the pregnant woman is yellow, although it can vary in different shades. These variations depend on the prenatal vitamins and other over-the-counter medicines or supplements, the diet we are eating and, above all, the hydration we have.
And it is that when drinking and ingesting less water, the color is concentrated more because the concentration of urochrome (a product of the breakdown of the hemoglobin of your dead red blood cells) gives your urine its normal range of yellow tones in and out of pregnancy. The more dehydrated you are, the darker your urine becomes.
It may be the case that the woman eats balanced and drinks two liters of water a day, but still there is a change in the color of the urine. The reason? Nausea and vomiting in the first trimester that sometimes lasts until the second trimester and that causes the woman not to properly metabolize everything in her body.
For all the reasons described above the color of your urine can range from dark yellow, amber, light orange, or brown. Watch your hydration (it is very easy to have symptoms of dehydration in pregnancy because there is a high demand in the body for fluids to maintain your volume of circulating fluid and normal metabolism) and you will notice the change.
You should also consider that you could have a urinary tract infection if your urine is very dark yellow or has a funny odor. But the color that should concern us and that is a more than justified reason to go to the emergency room is red. When this occurs (micro or microhematuria) it may be an infection.
