Why Does The Urine Color Change During Pregnancy?

Pregnant women frequently notice changes in their urine color which differ from normal pale yellow to a darker shade. This is normal in most cases, while it can be an indication of pregnancy-related issues in certain cases.  These changes are attributed to a multitude of factors.   

What Gives Color To The Urine?

Urochrome is a chemical component in our body that gives color to urine. It is also known as urobilin. It is produced when there is a breakdown of hemoglobin in our body. The concentration of urobilin decreases when our body is hydrated enough to dilute the urine. But if the body is not well hydrated due to a decrease in water intake, the urobilin becomes concentrated, changing the urine color from pale yellow to a darker shade.

Pregnancy has a lot of influence on the color of urine as it hugely alters the body’s function and hormone levels. Apart from physiological change, the consumption of certain medications and vitamins, along with changes in the diet can affect the color of urine.

What Is Normal Urine Color?

The normal color of urine is pale yellow and it indicates proper body function and hydration. However, urine color can vary from person to person, depending on diet, medication, lifestyle, etc. Changes in urine color can have different reasons. For instance, completely clear urine might indicate overhydration while darker urine can indicate a lack of some fluids. 

During pregnancy, the blood supply to the kidney increases, and there are huge changes in the hormones. This can cause urine color changes. But if the person’s health is fine and properly hydrated, the urine color can remain pale yellow. Generally, if the urine is cloudy or unusually dark, it might indicate an underlying health problem and is advised to consult a doctor.
