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

27. Low Exercise Tolerance

If your workouts suddenly feel harder, or you tire quickly doing things that used to feel easy, your gut could be interfering with energy production. An imbalanced microbiome can impair nutrient absorption (like B vitamins and magnesium), disrupt mitochondrial function, and even increase muscle soreness by promoting inflammation. Instead of pushing harder, focus on replenishing from the inside. Eat a diverse, colorful diet that supports microbial diversity, and consider adding fermented foods post-workout to aid recovery. As your gut heals, so does your stamina—restoring the energy and endurance your body is designed to have.

28. Unexplained Hair Loss or Thinning

If you're noticing unexplained hair loss or thinning, your gut microbiome could be the culprit. A healthy gut is essential for the absorption of key nutrients like iron, zinc, and biotin, all of which are critical for hair growth. Gut dysbiosis can impair this absorption, leading to nutrient deficiencies that manifest as hair loss. Additionally, gut-induced inflammation can affect hair follicles, disrupting the hair growth cycle. Addressing this issue involves supporting your gut with a diverse, whole-food diet, which in turn helps ensure you're absorbing the nutrients your body needs for a healthy head of hair.
