EXTREMELY FOUL GAS
WHAT THIS SYMPTOM USUALLY MEANS
Very foul-smelling gas indicates poor digestion, malabsorption, diet intolerance, parasites, or dysbiosis. When gas becomes unusually strong or persistent, it reflects deeper GI imbalance.

HOW THIS SYMPTOM RELATES TO LONGEVITY
Chronic GI imbalance leads to inflammation and reduced nutrient absorption — both accelerate aging.
WHEN TO CONSIDER A LONGEVITY CONSULT
• Chronic foul gas
• Senior pets
• Suspected EPI or IBD
