Drinking More Water May Help with Migraine and UTI: Systematic Review Finds - Video
|
Overview
Researchers at UC San Francisco have found that drinking enough water can help with weight loss and prevent kidney stones, as well as migraines, urinary tract infections and low blood pressure.
“For such a ubiquitous and simple intervention, the evidence hasn’t been clear and the benefits were not well-established, so we wanted to take a closer look,” said senior and corresponding author Benjamin Breyer, MD, MAS, the Taube Family Distinguished Professor and chair of the UCSF Department of Urology.
The study, which analyzed 18 randomized controlled trials was published in JAMA Network Open.
The researchers found the most evidence in favor of drinking water to prevent kidney stones and to help people lose weight. Several studies found that drinking about six cups of water a day helped adults lose weight. But a study that included adolescents found that drinking a little more than eight cups of water a day had no effect.
Still, the authors said that encouraging people to drink water before meals would be a simple and cheap intervention that could have huge benefits, given the increased prevalence of obesity.
Other studies indicated that water can help prevent migraines, control diabetes and low blood pressure, and prevent urinary tract infections. Adults with recurrent headaches felt better after three months of drinking more water.
Drinking about four more cups of water a day helped diabetic patients whose blood glucose levels were elevated. Drinking an additional six cups a day of water also helped women with recurrent urinary tract infections. It reduced the number of infections and increased the amount of time between them. And drinking more water helped young adults with low blood pressure.
“We know that dehydration is detrimental, particularly in someone with a history of kidney stones or urinary infections,” said Breyer, who is a member of the UCSF Department of Epidemiology and Biostatistics. “On the other hand, someone who suffers from frequent urination at times may benefit from drinking less. There isn’t a one size fits all approach for water consumption.”
