Pregnancy and kidney problems...!

Dr. Vani D | March 8, 2021.



Though pregnancy is a physiological process most of the time, it can cause kidney problems in some of the women.

Urinary infections (cystitis)

Painful urination with frequency is common in patients with urinary bladder infection.


The volume and size of the Kidneys increase in pregnancy by about 1 cm, because of this some of pregnant women are particularly susceptible to ascending pyelonephritis as a result of bladder infections

Kidney stones

Severe abdominal (or) flank pain along with passage of blood in the urine due to kidney stones is common in some pregnant women

Acute kidney injury

Most common cause of Acute Kidney Injury in pregnancy is dehydration owing to hyperemesis gravidarum i.e excessive vomiting.

Hypertensive diseases

These include gestational hypertension, pregnancy induced hypertension, existing hypertension of any cause and Pre-eclampsia superimposed on pre-existing hypertension.

Gestational hypertension

Pregnant women with BP greater than 140/90 mmHg without loss of protein in urine and whose BP was lower before pregnancy are described as having gestational hypertension.

Pre-eclampsia (Pregnancy Induced Hypertension)

It is the most common renal complication of pregnancy. It is characterized by new onset of hypertension after 20 weeks of pregnancy BP >140/90 mmHg associated with loss of protein in urine and swellings of legs.


It should be given according to the category with anti hypertensive medications


At Ainu, we have best Kidney Urologist doctors in Hyderbad related problems are common during pregnancy which should be evaluated at the earliest and taken care by team of health personnel.


Women who have Acute Kidney Injury and pre-eclampsia during pregnancy are at a higher risk of high blood pressure and CKD (Chronic kidney disease) later in life.
If the existing kidney problem is in proper control in terms of renal function tests and blood pressure, one can have a successful pregnancy under a close monitoring of nephrologist.
Gaining too much weight during pregnancy rasies your chances of getting High Blood Pressure. Gaining appropriate weight by healthy eating, doing moderate physical activity and Left LAteral Sleeping Posture (Left side is prefered to Right Side) will help to avoid leg swellings and high blood pressure.
