The gut microbiome influences immune function, mental health, hormonal regulation, weight management, skin health and energy, yet leaky gut often leaves people managing symptoms for years rather than resolving the underlying cause.
Jake’s clinical approach starts with a thorough intake including current symptoms, health history, recent investigations, diet and lifestyle and builds a plan specific to your leaky gut, not a generic protocol pulled from the internet.
Whether you are newly diagnosed with Leaky gut, have tried everything or simply know something is off, this is the level of leaky gut care that actually moves the needle.

Serotonin is produced in the gut, the gut-brain axis directly shapes mood and cognition
Chronic bloating
Daily bloating that does not resolve with dietary changes signals increased intestinal permeability.
Abdominal pain
Recurrent pain or cramping that disrupts meals, sleep or daily function indicates active leaky gut patterns.
Constipation cycles
Slow, incomplete or infrequent bowel movements that cycle unpredictably reflect impaired gut motility.
Explosive diarrhoea
Sudden, urgent or watery stools point to gut lining irritation, increased intestinal permeability.
Post‑meal discomfort
Pain within minutes of eating suggests irritation of the gut lining and heightened sensitivity associated with active leaky gut.
Food intolerance expansion
A growing list of foods causing symptoms indicates worsening gut barrier permeability.
Unpredictable flare cycles
Symptoms that spike without clear triggers show unstable gut regulation driven by gut lining irritation.
Self-management failure
When supplements, diet changes or online protocols fail, it reflects deeper gut‑lining dysfunction.

No, you do not need a formal gut health diagnosis to book. Many clients come in with bloating, abdominal discomfort, irregular bowel habits or unresolved digestive symptoms without a clear label. Jake will conduct a thorough intake, review any existing investigations and may recommend further testing where appropriate. A diagnosis helps, but it is not required to get started.
A gastroenterologist manages the medical and diagnostic aspects of gut health, while Jake builds a personalised nutrition strategy that restores gut function, reduces inflammation and stabilises daily leaky gut symptoms. They work differently, and many clients choose to work with both for the most complete care.
No, you will not be placed on a highly restricted diet. Jake’s approach is structured, personalised and clinically guided, but it is designed to be sustainable and flexible.
The goal is to rebuild nourishment and support long‑term digestive progress and gut stability while keeping your diet as broad and enjoyable as possible.
Most people actually gain more dietary freedom over time, not less.
Most clients begin noticing meaningful changes within the first few weeks.
Improvements often include better energy, more stable digestion, reduced bloating and clearer structure around what their gut needs.
Gut healing itself evolves over time, but the behaviours that support gut‑lining repair, calm inflammation and relieve leaky gut symptoms begin shifting almost immediately.
Jake monitors your progress closely and adjusts your plan so you continue moving forward with confidence.
Yes, Jake can work alongside your GP or Gastroenterologist.
