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

23. Lightheadedness After Meals

Feeling dizzy or spaced out after eating? It could be your gut microbiome interfering with blood sugar regulation. Dysbiosis can affect insulin sensitivity and slow carbohydrate breakdown, leading to post-meal blood sugar spikes or crashes. This rollercoaster can leave you lightheaded, sluggish, or anxious within minutes of eating. The fix? Balance your plate—pair fiber-rich veggies with protein and healthy fats to stabilize glucose response. Cut down on refined carbs and added sugars, and consider fermented foods to help rebalance gut flora. If symptoms persist, a glucose monitor or microbiome test could offer deeper insight.

24. Strong Body Odor (Despite Good Hygiene)

When your gut is out of balance, waste products aren’t metabolized efficiently—leading to more toxins being excreted through sweat. This can result in unexpectedly strong body odor, especially if your diet is high in processed foods or sugar, which feed the “bad” microbes. Instead of masking it with deodorants, start from within. Focus on high-fiber, plant-forward meals that support detoxification, drink plenty of water, and consider adding chlorophyll-rich foods like parsley or spirulina. A healthy microbiome doesn’t just help you feel better—it helps you smell fresher too.
