Dehydration can darken urine, and urinary tract infections, which are more common in pregnant woman, can turn urine bloody or cloudy, writes Mayo Clinic. Vitamin consumption can also change urine color, states Today I Found Out.
A pregnant woman needs to drink more fluid than a non-pregnant woman to stay hydrated, according to the Mayo Clinic. The Institute of Medicine guidelines suggest that a pregnant woman consume about 10 cups of fluids daily. This includes the fluid content of the foods she eats. Urine color can indicate if a woman is sufficiently hydrated; darker urine, regardless of whether an individual is pregnant, may suggest dehydration, writes WebMD.
From weeks six through 24, pregnancy increases the risk of urinary tract infection, states the American Pregnancy Association. Cloudy and bloody urine are two symptoms of urinary tract infection.
Other color changes are normal and do not indicate any problems. For example, prenatal supplements and other vitamins can turn urine neon-yellow or orange, writes Today I Found Out. B vitamins, and B2 in particular, may cause this color change. In both a pregnant and non-pregnant woman, certain foods can change the appearance of urine, according to the Mayo Clinic. The foods most likely to change the color of urine include beets, berries and fava beans.
