Blood in urine during pregnancy

During pregnancy, blood in the urine may be due to gallstones or kidney stones. However, the most common cause of the presence of blood is the presence of a urinary tract infection.
Here is an overview of the causes and symptoms of hematuria in pregnancy.

Causes of blood in urine during pregnancy

There are several possible reasons for blood in the urine during pregnancy, these reasons vary from severe conditions such as cancers of the bladder to minor reasons, such as viral infections.
Here is a list of the most common causes of hematuria during pregnancy.

Urinary tract infection

Urinary tract infection is one of the most common causes for the appearance of blood in the urine.
As the uterus grows, its weight can block the drainage of urine from the bladder, thus causing an infection that results in the presence of blood or mucus in the urine.



Kidney stones and gallstones

Blood in urine during pregnancy can also be the result of kidney stones that can cause severe pain and bleeding when the stones pass through the urinary tract.

The presence of hardened mineral deposits in the kidney can also cause constant pain in the abdomen, especially around the kidney area, and is accompanied by nausea or vomiting. In addition, the mineral deposits can build up in the bladder and form stones that cause pain and bleeding because they block the bladder.

Kidney problems

Hematuria can also be caused by damage to the upper urinary tract or kidney disease.

Bladder cancer, kidney

The presence of blood in the urine can also indicate cancer of the bladder or kidney and may be a symptom of prostate cancer in humans.

Other conditions

In addition, blood in the urine is detected in pregnant women with medical conditions such as lupus, sickle cell disease or diabetes. In most cases, a high amount of protein is present in the urine.

Symptoms when blood in the urine

Symptoms associated with hematuria may be different during pregnancy.

Blood in the urine is itself a symptom of hematuria during pregnancy.

For pregnant women with the macroscopic hematuria, the urine appears pinkish, red, or brown, with small blood clots.
