UTI symptoms

If you have had a UTI before, you know that it can be a painful and very disruptive condition. 

You can have one or more of the following symptoms: 

  • Frequent urination
  • Painful urination
  • Cloudy urine
  • Blood in the urine
  • Changes in the smell of urine
  • Abdominal pain
  • Fatigue
  • Fever

If you have symptoms of UTI, you should always consult with your doctor or healthcare provider. 

UTI causes

There are two main reasons you can get a UTI.  First is the presence of harmful bacteria in the urinary tract. The second is a weakened immune system.  This can be due to poor nutrition, a poor microbiome, stress, and more. 

You can definitely have both of these issues at the same time. 

Other contributing factors to UTI include: 

  1. Age
  2. Dehydration
  3. Antibiotic use
  4. Sexual activity
  5. Bacterial vaginosis
  6. Diabetes
  7. Sugar and processed foods
  8. Gender

The most common bacteria that cause UTIs is Escherichia coli or E. coli, which comes from the digestive tract. 

It turns out that the urinary tract also is protected by a healthy urinary microbiome. This just means that the urinary system is protected by beneficial bacteria or probiotics too. Common probiotics in the bladder and urethra are Lactobacillus, Streptococcus, and Actinomyces.

How common are UTIs?

Urinary tract infections are common in both women and men, but women get the brunt of the infection burden. In fact, 50-60% of all women get at least one UTI in their lifetime. 

About 12% of men will have a UTI, so it’s still really common in men, too. Children also can end up getting urinary tract infections. 

Additionally, the rates continue to increase over time, with over 150 million people per year worldwide having them. In the last 10 years, the rates of UTI have skyrocketed. 

Obviously, this is a costly and painful condition that can become serious if it turns into a kidney infection. The increased rates also point to the fact that people aren’t getting healthier; the opposite if anything. 

Additionally, standard treatment, which is antibiotics, increases the risk of further infections because it disrupts a healthy microbiome if probiotics aren’t added. 

Role of probiotics in the urinary tract

While research is still in the early stages of understanding the urinary microbiome, we do know that by supporting vaginal and gut health, probiotics reduce the risk of opportunistic infections in general. 

Probiotics that live in the urinary tract line the walls of the bladder and urethra which makes a protective barrier from harmful bacteria. They also likely compete with E. coli, making it less likely for an infection to set in. 

The microbiome from the gut also supports a healthy immune response throughout the whole body, making probiotics an appealing choice for UTI prevention. 

Which are the best probiotic strains for UTI?

Antibiotics remain the first-line treatment for UTIs.  But, probiotics can help reduce the need for future antibiotics by supporting the immune system and fighting invading bacteria.

For example, one study found that postmenopausal women who received probiotics called Lactobacillus rhamnosus GR-1® and Lactobacillus reuteri RC-14® or an antibiotic had half the number of infections compared to no treatment. 

The probiotic treatment fared better than the antibiotic group in the end because there was less antibiotic resistance at the end of the year of treatment. 

Another study found similar results.  People with recurrent UTIs had a 50% less chance of recurrence when taking L. rhamnosus GR-1® and L. reuteri RC-14® over 6 months. 

Additionally, children who have low levels of Bifidobacterium and high levels of E. coli in their gut have a much higher chance of getting a UTI. 

A probiotic called Lactobacillus crispatus reduces the risk of recurrent UTIs by almost 50% as well.  This probiotic was used as a vaginal suppository in this particular study. 

Still another study found that using Bacillus subtilis plus antibiotics worked better than antibiotics alone for reducing UTIs in people with recurrent infections. One way that this strain helps with UTIs is because it may reduce antibiotic resistance

When it comes to the urinary tract, Saccharomyces boulardii is another strain that holds promise because it reduces the growth of E. coli. 

Also for preventing UTIs, probiotics seem to also help prevent infection in children.  A wide variety of probiotic strains seem to help.

Diet tips for UTI prevention

There are many things you can do to help reduce the risk of UTI.  Eating healthy foods that support gut health should be a cornerstone.  

Some foods for gut health and urinary health include:

Probiotic foods and citrus fruits are related to a reduced risk of getting UTIs. 

Other ways to help prevent UTI

Protecting your urinary tract should be holistic and the following tips are general suggestions to help reduce your chances of infections. 

  • Stay hydrated
  • Eat a well-balanced diet
  • Avoid processed foods
  • Add in D-mannose supplements
  • Eat fermented foods
  • Optimize your vitamin D levels
  • Urinate after sex
  • Eat prebiotic foods
  • Remain properly hydrated
  • Support your gut health
  • Minimize stress

Additionally, make sure to check with your healthcare provider about specific health tips you should follow for your individualized health. 

How to choose the best probiotics for UTI prevention

When choosing a probiotic strain to help urinary tract infections, look to the research to see what strains are used.  

Most research has used two strains of probiotics to help prevent UTIs: Lactobacillus reuteri and Lactobacillus rhamnosus.

However, other types of probiotics like Saccharomyces boulardii reduce the growth of E.coli, which is the most common culprit in causing urinary tract infections.

Not only that but using probiotics also may prevent candida infections in the urinary tract as well. 

Still, other probiotics called soil-based probiotics may reduce stubborn bacterial biofilms which make UTIs difficult to treat. The strains used in this study were  Lactobacillus acidophillus, Lactobacillus rhamnosum, Bifidobacterium longum, Bifidobacterium bifidum, Saccharomyces boulardii, and Streptococcus thermophilus.

So, although we can’t necessarily say that probiotics help treat urinary tract infections, the odds are that they can help prevent you from getting a UTI in the first place or prevent a secondary urinary tract infection. 

Plus, the health benefits of probiotics aren’t just for the urinary tract.  They help almost every system in the body, including the digestive tract.

Commonly asked questions

Can probiotics cause UTI?

No.  There are no case reports of UTIs with probiotic use or research studies showing that probiotics can cause UTIs.  Still it’s always best to check with your healthcare provider before starting probiotic supplements. 

Do probiotics need to be refrigerated?

Typically no.  However, certain types are best refrigerated.  The supplement label will indicate if you should refrigerate your probiotics. 

When is the best time to take probiotics?
