Keto And Uti: Is There A Link?

The ketogenic diet is a high-fat, moderate-protein, low-carb diet that switches the body's metabolic state from burning glucose to burning fat. While this diet has been hailed for its ability to provide benefits such as weight loss and improved mental clarity, it also comes with some side effects. One of the most unique symptoms of the keto flu is keto breath, which is caused by an excess of ketones in the body. This leads to the question of whether the keto diet changes the composition of urine and, if so, what effect this has on the urinary tract. In this regard, there is some evidence to suggest that the keto diet may be linked to urinary tract infections (UTIs).

Keto diet can cause hormonal disruptions in women, leading to vaginal odour and UTIs

The keto diet, which involves significantly reducing carbohydrates and increasing fats, can cause hormonal disruptions in women, potentially leading to vaginal odour and UTIs.

The increase in acidic, high-fat foods can impact the hormonal balance in women, causing a shift in the vaginal microbiome. This shift can lead to a range of issues, including an unpleasant vaginal odour, known as "keto crotch." While studies have not confirmed this phenomenon, doctors agree that the change in diet could disrupt the vaginal pH, creating an environment conducive to the growth of infection-causing bacteria.

This disruption in vaginal pH can have several negative consequences, including bacterial vaginosis, yeast infections, and, indeed, UTIs. The growth of these bacteria can be attributed to the vagina becoming more alkaline due to the highly acidic diet. This imbalance allows bacteria to multiply, leading to potential infections and related health issues.

While the keto diet can offer benefits such as weight loss and improved mental clarity, it is important to be aware of these potential side effects, especially for women. The disruption in hormonal balance can have far-reaching consequences for overall health and well-being.

Additionally, the keto diet can lead to other issues such as vitamin deficiencies and disruptions in menstrual cycles, further highlighting the need for caution when considering this diet, especially for women.

Keto diet may help prevent UTIs by lowering sugar levels in urine

The keto diet is a high-fat, moderate-protein, low-carb diet that retrains the body to use fat sources for energy instead of carbohydrates and sugars. This shift in metabolic state can help stabilise blood sugar levels and reduce the risk of type 2 diabetes and metabolic syndrome.

One of the causes of UTIs is sugar in the urine, which creates a breeding ground for bacteria. Therefore, a keto diet that reduces sugar levels in the urine may help prevent UTIs.

A 1933 study found that out of 16 UTI cases, 5 were cured by the keto diet, 4 were cured by adding ammonium nitrate to keto, and 2 were cured by adding hexamine. While the keto diet cannot completely sterilise the urine, it can offer an additional level of protection against UTIs.

However, it is important to note that the keto diet can also cause an array of health issues in women, including hormonal disruptions, bad breath, and "keto crotch," which refers to an unpleasant vaginal odour caused by a disruption in vaginal pH. This disruption in vaginal pH can lead to bacterial vaginosis, yeast infections, and UTIs. Therefore, while the keto diet may help prevent UTIs in some people by lowering sugar levels in the urine, it can also potentially cause UTIs in women due to changes in vaginal pH.

Keto diet can increase the risk of UTIs by changing the content of urine

The keto diet can increase the risk of UTIs by changing the content of urine. The ketogenic diet involves significantly reducing carbohydrates and increasing fats, which leads to a metabolic state called ketosis where the body burns fat for energy instead of carbohydrates. While this can lead to accelerated weight loss, it also changes the composition of urine.

Ketones, the molecules produced when the body breaks down fat for energy, are present in the urine of people following a keto diet. This can alter the pH of the urine, making it more alkaline. While a higher pH can help prevent the growth of bacteria that cause UTIs, such as E. coli, it can also create an environment in the vagina that allows infection-causing bacteria to multiply. This imbalance of vaginal flora can lead to bacterial vaginosis, yeast infections, and UTIs.

Additionally, the keto diet can cause a spike in the stress hormone cortisol, which can disrupt the hormonal balance in women. This hormonal shift can further impact the vaginal microbiome, making it more susceptible to infections.

The keto diet's effect on urine pH and vaginal flora demonstrates how it can increase the risk of UTIs by altering the content of urine. However, it's important to note that other factors, such as dehydration and holding urine for too long, can also contribute to the development of UTIs. While the keto diet may increase the risk for some individuals, it's not the sole cause of UTIs, and other factors specific to an individual's health and lifestyle should also be considered.

To counteract the potential negative effects of the keto diet on urinary tract health, it is recommended to increase the intake of alkaline and prebiotic-rich foods, such as dark leafy greens, cruciferous vegetables, garlic, and asparagus. Supplementing with probiotics can also help balance the vaginal microbiome and prevent UTIs.

Cranberries and blueberries can help prevent UTIs by binding with bacteria and preventing them from attaching to the urinary tract walls

Cranberries and blueberries can be effective in preventing UTIs. They do this by binding with bacteria and preventing them from attaching to the urinary tract walls. This is especially true for women who are prone to UTIs.

Cranberries have been used to treat UTIs since ancient times. The North American Indians used the American cranberry to treat UTIs. The berries are composed of water, organic acids, fructose, vitamin C, flavonoids, anthocyanidins, catechins, and triterpinoids. The chemical constituents responsible for their taste are the iridoid glycosides.

The current hypothesis is that cranberries work by preventing the adhesion of type 1 and p-fimbriae strains (particularly from E. coli) to the urothelium. Without adhesion, the bacteria cannot infect the mucosal surface. Cranberries contain fructose, which inhibits the adherence of type 1 fimbriae, and PAC, which inhibits the adherence of p-fimbriae. The binding of the proteinaceous bacterial fimbrial tips to mucosal surfaces on the uroepithelium occurs as a specific receptor–ligand association favored by hydrophobic interactions. One possible mechanism is that the cranberry compounds, acting as receptor analogs, competitively inhibit the adhesion of E. coli to host cells by binding to the fimbrial tips.

Blueberries can do the same as cranberries, so if you prefer the sweeter taste of blueberries, you can still get the same anti-bacterial benefits.

Prebiotics and probiotics can help prevent UTIs by increasing good bacteria in the gut

Prebiotics and probiotics can help restore and maintain a healthy balance of bacteria in the body, which is essential for preventing UTIs. Probiotics, especially those containing strains from the Lactobacilli family, are beneficial in preventing UTIs. Lactobacilli are present in healthy, premenopausal women, and maintaining a balance of these probiotic bacteria may support the body in fighting off the pathogens that cause UTIs.

Probiotics have been shown to have a positive effect on preventing UTIs by strengthening the gut microbiome. Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 are the most effective probiotic strains for preventing UTIs. Additionally, prebiotics like bananas, oats, and chicory root can feed the good bacteria in the gut, while probiotic foods like kefir, Greek yogurt, and kimchi add more active good bacteria to the gut's population.

By increasing the number of good bacteria in the gut, prebiotics and probiotics can help prevent UTIs by inhibiting the growth of bad bacteria and maintaining a healthy bacterial balance in the body. This, in turn, can reduce the risk of infection and improve overall health.
