Stroke
Stroke happens when blood flow to part of the brain is interrupted (ischaemic stroke) or a blood vessel bursts (haemorrhagic stroke).
Overview
Stroke happens when blood flow to part of the brain is interrupted (ischaemic stroke) or a blood vessel bursts (haemorrhagic stroke). It’s a leading cause of death and disability worldwide and in Australia. Recovery can vary widely; untreated risk factors raise the chance of recurrence and long‑term disability. Frontiers
Common Misunderstandings
Many assume stroke only affects older people, yet it can occur at any age. After discharge, patients often feel overwhelmed by fatigue, mood changes and gut issues (constipation, poor appetite). Families commonly ask what else—beyond tablets—can help lower risk and support recovery.
How is a Stroke Linked to Your Microbiome?
- Animal and human studies show the gut–brain axis influences stroke injury and recovery. In mice, altering gut bacteria changed infarct size; effects were transferable via faecal transplant, implicating immune pathways. Nature
- After stroke, the gut community often becomes imbalanced (dysbiosis), which can worsen inflammation and infection risk; reviews highlight the microbiome as a potential target in acute ischaemic stroke. FrontiersSpringerLink
- Gut‑derived metabolites such as trimethylamine‑N‑oxide (TMAO) have been linked to higher stroke risk in cohort studies; dietary patterns that raise TMAO (via gut conversion of choline/carnitine) are under scrutiny. AHA JournalsScienceDirect
