Hazy Urine in Pregnancy: Scientists Reveal the Hidden Causes (Backed by Experts) Pregnancy brings a wide range of physical changes—many expected, and some surprising. Among the lesser-discussed but notably common signs is hazy or cloudy urine. While a slight change in urine color or clarity can stem from normal pregnancy-related factors, persistent or worsening haziness may signal an underlying issue that deserves attention. Backed by medical experts and scientific research, this article explores the hidden causes of hazy urine during pregnancy and what expectant mothers should know. ### What Should Normal Pregnancy Urine Look Like? In early to mid-pregnancy, mild changes in urine—such as slight cloudiness or a faintly amber hue—are relatively common. This can result from increased metabolic activity, rising levels of estrogen, and subtle shifts in hydration. However, clear, pale yellow urine typically signals proper hydration, while persistent cloudiness, strong odor, or foaminess often points to more than just routine changes.
