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

25. Heightened Pain Sensitivity

If everyday discomforts—like headaches, period cramps, or sore muscles—feel unusually intense, your gut might be influencing your pain threshold. Dysbiosis can disrupt the gut-brain axis and increase systemic inflammation, amplifying how your body perceives pain. Some gut bacteria even play a role in regulating neurotransmitters tied to pain modulation. Healing starts with anti-inflammatory support: turmeric, flaxseed, and wild-caught fish can help. Prioritize sleep, reduce ultra-processed foods, and consider introducing probiotics with Lactobacillus and Bifidobacterium strains. Restoring microbial balance may literally help take the edge off physical discomfort.

26. Eye Dryness or Irritation

The gut and eyes may seem unrelated, but research shows a strong link between gut health and the moisture barrier of your eyes. An imbalanced microbiome can trigger inflammation that affects tear production and eye surface health—leading to dryness, redness, or light sensitivity. This connection is especially strong in people with autoimmune or skin conditions. To support both gut and eye health, focus on omega-3s, antioxidant-rich produce (like carrots and leafy greens), and hydration. Adding gut-friendly fermented foods and minimizing processed foods can calm inflammation system-wide, including in your eyes.
