Smelly urine when pregnant is one of the several unusual symptoms one might experience. While it is not always a cause of concern, it may be uncomfortable for expecting mothers.
While some cases could indicate underlying pathology, it is essential to get examined by the doctor to rule out any infections or other problems causing smelly urine. Also, some care and precaution are essential in avoiding smelly urine during pregnancy. Read this post to learn the various causes and preventive measures of smelly urine during pregnancy.
Causes Of Smelly Urine During Pregnancy
Urine can smell different during pregnancy due to a heightened sense of smell, more urea in the urine, urinary tract infections, and even changes in diet. Most of these causes are usually benign and seldom to worry about.
Below is a list of the common causes of smelly urine in pregnant women.
- Heightened sense of smell: It is believed that pregnancy might increase sensitivity to odors, also known as hyperosmia. Ammonia is naturally present in urine, but the smell is usually not strong. Due to the increased sense of smell in pregnancy, you can notice a bad odor. However, there is no medical evidence to establish a connection between increased olfactory response and pregnancy (1).
Dr. Brittany Noel Robles, a New York-based obstetrician-gynecologist, says, “An ammonia-like smell from urine may be caused due to different reasons such as dietary changes, vitamin ingestion, or dehydration. Dehydration can cause urine to become more concentrated and produce a stronger smell. However, a strong smell could also be a sign of a urinary tract infection, so it is important to speak with your healthcare provider if you have any concerns.”
- Urinary infections: Urinary tract infection is a bacterial inflammation or yeast infection in the urinary tract and is common in pregnancy. As per the reports of a study by multiple institutions, the rates of UTI in pregnancy was estimated to be between two and seven percent. Urinary tract infections during pregnancy can cause cloudy urine, which smells foul or unusual (2).
- Bacterial infections: Bacterial vaginosis or vaginitis is a vaginal infection caused by the overgrowth of bacteria. It may lead to a burning sensation and foul smell while peeing
- Diet: You may have weird food cravings in pregnancy. Certain foods, including cauliflower, broccoli, asparagus, garlic, coffee, and beer, can give the urine a temporary, strong odor (4).
- Supplements: Certain medications, vitamins, minerals, etc., can cause an unpleasant urine odor. However, do not stop the medicines without consulting your doctor (4).
- Dehydration: You should consume enough water for both your and the baby’s well-being. Otherwise, dehydration in pregnancy may lead to foul-smelling urine (5).
Tips To Help Reduce Urine Odor During Pregnancy
The following tips can help you avoid foul urine smell during pregnancy.
- Drink six to eight glasses, or 1.5 to 2 liters of water or other fluids every day. Consuming sufficient fluids can prevent dehydration and foul-smelling urine (5).
- Maintain good hygiene to help prevent foul smells. For example, bathing regularly, wiping from front to back each time after peeing, using mild, non-fragrant soaps to clean the genitals, etc., can protect the vagina from infections and foul smells.
- Anecdotal evidence suggests that cranberry juice and apple cider vinegar can help acidify the urine, reducing the foul smell from the urine.
- Empty the urinary bladder frequently to prevent urinary stasis, which can lead to an increased risk of UTIs, bladder infection, cystitis, and bad odor.
- Avoid multiple sex partners and intercourse without male latex condoms to help prevent UTIs or sexually transmitted infections (STIs) that may cause smelly urine.
- Probiotics are considered to be beneficial in promoting vaginal health for women. According to some clinical studies, consuming probiotics can help cure bacterial vaginitis and reduce its recurrence (6).
