microbiome

Your gut is home to roughly 38 trillion bacteria, contains more neurons than your spinal cord, and sends more signals to your brain than it receives back. Here is the full mechanism — from the first bite to the last cell.

Symbiosis is one of the most powerful forces in evolution. From the bacteria in your gut to the fungal partners of nearly every land plant, the living world is a web of intimate partnerships, and not all of them are friendly.

Borborygmi explained: why your stomach growls when hungry, after meals, and in quiet rooms — plus when those sounds signal a real problem.

Your skin hosts ~1,000 bacterial species, fungi, viruses, and mites. How the skin microbiome shapes acne, eczema, odor, and immunity.

IBS involves visceral hypersensitivity, gut motility changes, and gut-brain signaling. Explore the biology behind IBS — not a diagnosis guide.

What the gut microbiome is, what it does for digestion, immunity and the brain, and which findings are well established versus still early research.

How understanding the microbiome revealed that trillions of bacteria impact health and disease

Your gut and brain exchange signals through nerves, immune cells, and microbial chemicals. Here is what animal and human studies show about mood, anxiety, and cognition, and where the evidence is still thin.
