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

49. Unexplained Muscle Aches or Soreness

Muscle pain that isn't tied to exercise can be a surprising indicator of an unhealthy gut. An imbalanced microbiome can lead to chronic, low-grade inflammation throughout your body. This inflammation can cause widespread muscle aches and stiffness, mimicking the feeling of an intense workout or a flu-like state. Additionally, a "leaky gut" can impair your body's ability to absorb essential minerals like magnesium and potassium, which are crucial for muscle function. Restoring your gut health can reduce this systemic inflammation, allowing your muscles to heal and function without unexplained pain.

50. Bumpy Skin on Your Arms or Thighs (Keratosis Pilaris)

That rough, bumpy skin on the back of your arms or thighs—often called "chicken skin"—is a less-known sign of gut trouble. Keratosis pilaris is caused by a buildup of keratin in hair follicles, and it's frequently linked to essential fatty acid and vitamin A deficiencies. An unhealthy gut microbiome and a compromised gut lining can significantly impair your body's ability to absorb these fat-soluble vitamins and healthy fats from your diet. Focusing on gut-healing, nutrient-dense foods can improve absorption, which can, over time, help smooth and clear up your skin.
