What Could Cause Foamy Urine? 12 Possible Triggers (List)

Preeclampsia and Hypertensive Pregnancy Disorders

Pregnant women can develop a condition known as preeclampsia relative to hypertension. They can also develop other types of hypertensive disorders, such as gestational hypertension, chronic hypertension, and chronic hypertension with superimposed preeclampsia.  

Preeclampsia is a condition wherein the patient has hypertension and may have proteinuria, which can signify kidney damage or other signs of organ damage. It manifests after 20 weeks of pregnancy, especially in women whose blood pressure levels are in the normal range. Preeclampsia can cause foamy urine and other complications for the mother and the offspring. Doctors cite severe headaches, increased liver enzymes, thrombocytopenia, and nausea and vomiting as among the symptoms of preeclampsia. 

Patients with preeclampsia and other pregnancy hypertensive disorders experience foamy urine because of the elevated protein levels in their bloodstream. Hypertension associated with the condition also causes damage to the glomeruli and other organ structures because of the constriction and narrowing of the blood vessels. In addition, kidney and liver damage during such complicated pregnancy can cause several substances to seep into the urinary tract. Foamy urine manifests when such substances mix with urine, coupled with urination speed. Doctors recommend taking the necessary medications to manage such conditions during pregnancy.
