best probiotics for urinary tract infection

Probiotics are live microorganisms that offer health advantages to humans when ingested in sufficient quantities. They are often referred to as “friendly” or “good” bacteria because they aid in balancing the bacterial population in the digestive system, urinary tract, and other areas of the body.

What is a Urinary Tract Infection (UTI)? 

UTIs are common infections that happen when bacteria, often from the skin or rectum, enter the urethra and infect the urinary tract. The infections can affect several parts of the urinary tract, but the most common type is a bladder infection (cystitis). A less common, but more serious UTI is pyelonephritis which involves an infection of your kidney. (Definition from CDC)

What are the symptoms of UTI?

Some generally common symptoms of UTI are as follows;

  • Pain or burning while urinating
  • Frequent urination
  • Feeling the need to urinate despite having an empty bladder
  • Bloody urine
  • Pressure or cramping in the groin or lower abdomen
  • Fever*
  • Chills*
  • Lower back pain or pain in the side of your back*
  • Nausea or vomiting*

*Indicate a more severe infection that may involve infection of your kidneys.

What causes UTIs?

Most UTIs are caused by bacteria of which the commonest one is Escherichia coli (E. coli), which normally lives in the gut as a commensal but can enter the urinary tract through the urethra. Some other common types of bacteria that cause UTI are Klebsiella, Proteus, Pseudomonas, and Staphylococcus saprophyticus. 

Less commonly, UTIs may also be caused by fungi, such as Candida, or viruses they are not the first priority the doctors used to consider when they see a patient with UTI. 

What are favorable conditions for UTI? 

Natural, Diseases or Iatrogenic Factors

Conditions that can increase the likelihood of developing UTIs include female anatomy (shorter urethra), sexual activity, urinary catheterization, menopause, certain medical conditions like diabetes, a weakened immune system, and congenital or urinary tract abnormalities or blockages or injuries. 

Relationship with Friendly Microbiota 

The urinary tract normally contains a diverse population of bacteria that help maintain a healthy balance and prevent the growth of harmful bacteria. UTIs can occur when there is an imbalance in the normal microbiota of the urinary tract, allowing harmful bacteria to grow and cause an infection.  

The above-mentioned conditions can disrupt the normal microbiota of the urinary tract and create an environment that is more hospitable to harmful bacteria allowing them to multiply dramatically causing several symptoms of UTI in the host.

How probiotics could help in Urinary tract infections? 

Probiotics, which are live microorganisms that offer health benefits, have been found to potentially help prevent UTIs and improve their symptoms.  By introducing beneficial bacteria to the urinary tract, probiotics can help prevent the growth of harmful bacteria and restore a healthy microbial balance.

What does the available research say?

A study published by National Institute of Health has suggested that certain strains of probiotics, such as Lactobacillus and Bifidobacterium, can help prevent the growth of harmful bacteria in the urinary tract by producing lactic acid and other substances that create an acidic environment. This acidic environment can prevent the growth of harmful bacteria and promote the growth of beneficial bacteria. 

Clinically significant research findings

A large double-blinded trial in 2018 found L. rhamnosus GR1 and L reuteri RC 14 , compared with antibiotics, showed “nearly as effective” as antibiotics. Apart from that, patients in the probiotics group observed less antibiotic resistance.

Another study on L. rahmnosis GR1 found it reduces the recurrence rate by around 20 %.

One study on L. acidophilus , L. rhamnosus, and Bifidobacterium bifidum, B lactis also showed a significant reduction in recurrence rates.

Personal advice

  • Do not rely on probiotics supplements ONLY if you have UTI symptoms
  • The main treatment is still the one that your doctor prescribed
  • Sometimes symptoms might need further investigations such as blood tests or urine cultures
  • Despite more evidence and theories coming out, currently, no clinical guidelines directly support the use of probiotics for this particular condition.
  • Probiotics are best obtained from dietary sources: check best probiotics foods
