Type 2 diabetes

195 associated organisms · Associations point to fewer butyrate producers and less Akkermansia — but many early findings were confounded by metformin, which itself reshapes the microbiome.

Symptoms of Type 2 diabetes can need medical evaluation. Treat these associations as background context only — please see a doctor rather than self-treating.
Organisms associated with Type 2 diabetes
Akkermansia muciniphila Beneficial Reduced in Type 2 diabetes
Species

This barrier-supporting species is lower with insulin resistance.

Moderate evidence source: curated sample
Faecalibacterium prausnitzii Beneficial Reduced in Type 2 diabetes
Species

Butyrate producers decline — but several studies were confounded by metformin, not diabetes itself.

Moderate evidence studies conflict source: curated sample
Butyrate-producing bacteria Community metric Reduced in Type 2 diabetes
Functional group

A broad reduction in butyrate producers is a recurring theme, plausibly linked to barrier and inflammation changes.
