Signs Your Gut Microbiome is Out of Whack (And How to Fix It)

19. Frequent Urinary Tract Infections (UTIs)

If you’re constantly battling UTIs, your gut might be the hidden culprit. The gut and urinary microbiomes are closely linked, and gut dysbiosis can lead to the overgrowth of pathogenic bacteria like E. coli—often the main cause of recurring infections. A weakened microbiome can also compromise the vaginal flora, reducing natural defenses. To lower your UTI risk, prioritize fermented foods (especially plain yogurt and kimchi), hydrate consistently, and reduce sugar intake, which fuels harmful microbes. Probiotics containing Lactobacillus strains are particularly helpful in restoring balance both in the gut and urinary tract.

20. Frequent Nausea Without Cause

Chronic, low-grade nausea that seems to have no clear source might be a sign your gut isn’t processing food properly. Imbalances in gut bacteria can slow gastric emptying or disrupt the communication between your gut and brain, leading to a vague, persistent queasiness. Small intestinal bacterial overgrowth (SIBO) is one common culprit. To ease symptoms, reduce fermentable carbs (like garlic, onions, and legumes), eat smaller meals, and consider a low-FODMAP diet temporarily under supervision. Long-term, slowly reintroducing probiotic-rich foods and supporting digestion with bitters or ginger can help your gut regain balance and calm the queasiness.
