About Mohammed Attallah

I am Mohammed Attallah, founder of BiomeLogic and an independent systems-biology consultant. I work with people navigating complex gastrointestinal, hormonal, immune and autonomic symptoms, reviewing their histories and existing results to organize the evidence into a clear, individualized mechanistic analysis.

My work is the careful reading of complex, multisystem chronic cases in people of every gender: recurrent SIBO, IBS and dysmotility; mast-cell and histamine reactivity; POTS and dysautonomia; post-infectious illness; bile-acid and metabolic patterns; and neurodevelopmental–gut questions. Women's perimenopause and hormonal–gut–immune overlap is one prominent specialty within that broader work. These are cases whose pieces are often investigated one specialty at a time. My role is to read them as one system — alongside, never instead of, your licensed care.

How I work

I read your case history and existing laboratory results end to end — chronology first, then every record in context. From that record I identify the relationships and competing explanations it can support, grade each candidate mechanism by the strength of its evidence, and state plainly what your existing tests cannot prove. Conceptual hypotheses are labelled as hypotheses; established evidence is labelled as established. The two are never blended into one narrative.

What you receive is a detailed written analysis of your case, a personalized intervention framework derived from it, structured questions to bring to your clinicians, and a live session where we test the reasoning together — including where it could be wrong and what would change it. 4 weeks of clarification email follow-up follow. You can inspect the format before deciding anything: the sample analysis is a complete fictional case, and the full method is described in how I work.

Why women's hormonal–gut–immune patterns are a focus

Responses to my recent writing and conversations with women navigating hormonal transitions have repeatedly raised questions about overlapping gut, histamine, autonomic and sleep symptoms. Those questions merit careful analysis without assuming hormones explain every finding. This is a prominent specialty alongside equally central GI, immune, autonomic and post-infectious case analysis.

This focus applies the same rigorous method — chronology, competing hypotheses and evidence grading — to overlapping hormonal, gut and immune questions, with conclusions written for a client's licensed clinicians. Complex multisystem cases in people of every gender remain welcome. Explore the women's health focus area →

The framework behind the analysis

The Host Capacity Model asks a question most gut work skips: not only which microbes are present, but what changed in the host environment that made their state sustainable. It examines epithelial fuel use, mitochondrial capacity, oxygen-gradient regulation, barrier integrity, immune signalling and motility as candidate upstream contributors — and it is evaluated case by case against competing explanations, including the possibility that it does not apply. The full framework, its evidence state and its open questions are published in the open: the model itself, the framework audit, and the claim ledger that separates settled physiology from working inference.

Scope

BiomeLogic is independent educational systems-biology case analysis. Findings are prepared for discussion with your licensed medical team; BiomeLogic does not diagnose, prescribe, or replace clinical care. I am not a licensed clinician, and no medical credential is claimed or implied. The full statement is on the scope of practice page.

The fit screen is free and takes about five minutes — no files, no payment, and a written reply by email either way.
