Dr. Rebecca Ryan
BMBS (Hons) FRACP
Gastroenterology & Hepatologist
Specialising in Disorders of the Gut-Brain Axis
Dr Ryan's health approach centers around the comprehensive examination of the entire Gut-Brain Axis, taking into consideration multiple factors, including Genetics, Diet, Exercise and Stress, and how they collectively contribute to your symptoms.
While acknowledging stress as a potential trigger and contributor for maintaining Functional Gut Symptoms, Dr Ryan's approach goes beyond attributing symptoms solely to psychological factors. Instead it underscores the significance of understanding the broader physiological connections between the Gut and the Brain, or THE GUT BRAIN AXIS
The Gut Brain Axis Explained
The Gut-Brain Axis (GBA) involves the two-way communication between the Gut and The Brain. In basic terms, the Brain regulates Gut Functions such as Digestion, Movement and Nutrient Absorption. On the other hand, the Gut, along with its Microbiome affect Brain Functions such as Mood, Memory and Appetite.
Components of the Gut-Brain Axis
The GBA is an incredibly complex, interconnected network consisting of,
-Direct Physical Connections
Nerves establish direct links between the Gut and the Brain, facilitating instantaneous communication.
The Brain, acts as the central control hub, which orchestrates this communication network.
The Autonomic Nervous System governs involuntary functions, and consists of Sympathetic Nervous System aka "Fight, Flight or Flee", Parasympathetic Nervous System aka "Rest and Digest", the Enteric Nervous System, is often referred to as the "Second Brain", as it operates independently within the gut.
-Indirect Connections
The Gut and Brain also communicate indirectly via Neurotransmitters, Hormones released by the Endocrine System and from Specialised cells in the Gut, and the Immune System
The Gut Bacteria, or Microbiome plays a pivotal role in all these interactions.
