SIBO After 60: The Hidden Gut Imbalance That’s Often Misdiagnosed as IBS

SIBO After 60: The Hidden Gut Imbalance That’s Often Misdiagnosed as IBS

Gas, bloating, and “IBS” that won’t resolve? In older adults, symptoms may be driven by SIBO—Small Intestinal Bacterial Overgrowth—where excessive bacteria settle in the small intestine and ferment foods prematurely.

“Treating SIBO is less about ‘killing bugs’ and more about restoring function—motility, digestion, and gut-immune balance.”

Why SIBO Is More Common After 60

  • Slower motility: Food and bacteria linger longer in the small intestine.
  • Low stomach acid or enzymes: Reduces natural defense against bacterial overgrowth.
  • Medications: Especially acid suppressants and opioids can predispose to SIBO.
  • Structural issues: Post-surgical changes, adhesions, or diverticula.

Common Symptoms

  • Bloating, gas, abdominal discomfort
  • Diarrhea, constipation, or both (IBS-like)
  • Food intolerances (especially to fermentable carbs)
  • Fatigue, brain fog, nutrient deficiencies (B12, iron)

Testing & Clinical Approach

  • Breath testing: Lactulose or glucose breath tests for hydrogen/methane; your clinician interprets alongside symptoms.
  • Address root causes: Motility support, medication review, digestive support, and gentle diet adjustments.
  • Therapies: Depending on the case—antibiotics, herbal antimicrobials, or prokinetics under medical guidance.

Nutrition & Supplement Support

While treatment is individualized, these can support gut comfort and recovery:

  • Young Again Curcumin: Calms GI-related inflammation and supports mucosal healing.
  • Young Again Omega-3 Fish Oil: Helps modulate inflammatory pathways linked to gut discomfort.
  • Young Again Magnesium Glycinate: Supports regularity and smooth muscle relaxation in the GI tract.

Note: Probiotics or prebiotics may help or aggravate symptoms depending on the phase—work with your clinician for timing and type.

The Takeaway

If you’ve been told it’s “just IBS,” consider evaluation for SIBO—especially with bloating soon after meals. The goal isn’t endless restriction; it’s restoring function and comfort so you can broaden your diet again.
