Gut-Brain & Digestive Health

When mental health starts in the gut.

Understanding it

The gut and the brain are connected

Your gut and brain are in constant conversation through the nervous system, immune signaling and the microbiome. When digestion is off, mood, focus and resilience often follow, and it can work the other way too.

  • Bloating, irregularity or ongoing digestive discomfort
  • Mood or anxiety that tracks with what you eat
  • Food sensitivities, cravings or unstable energy
  • Brain fog that improves or worsens with meals
Gut-Brain & Digestive Health

The gut and brain talk constantly

The gut and the brain are linked through the vagus nerve, hormones, immune signals and compounds produced by gut bacteria. That is why stress can upset your stomach within minutes, and why digestive problems so often travel with anxiety, low mood and brain fog. When both are happening, treating them together tends to work better than treating either alone.

Signs the gut-brain connection may be involved

  • Bloating, reflux, abdominal pain, constipation or diarrhea alongside anxiety or low mood
  • Digestive flares that follow stressful periods
  • Food-related anxiety or a narrowing diet
  • Fatigue and brain fog with ongoing gut symptoms
  • In children, especially autistic children, constipation or stomach pain linked with behavior changes

Red-flag symptoms such as blood in the stool, unintended weight loss, persistent vomiting, trouble swallowing or severe pain need prompt medical evaluation.

How we approach gut-brain problems

Assessment

We take a detailed history of digestive symptoms, diet, stress, sleep and medications, and coordinate with your primary care provider or gastroenterologist on any medical workup. Targeted labs can check for problems such as anemia, celiac disease screening, thyroid issues or nutrient deficiencies when your history suggests them. See lab testing for mental health.

Nutrition

We build a varied, fiber-rich eating pattern that suits your digestion, introduce changes gradually, and avoid unnecessary restriction. Where a short, structured elimination approach makes sense, we plan it carefully and reintroduce foods. See nutritional psychiatry.

Calming the stress response

Breathing techniques, relaxation training and gut-directed therapy approaches can reduce both anxiety and digestive symptoms. See anxiety and panic.

Sleep and routine

Regular sleep and meal timing support both gut function and mood. See sleep and insomnia.

Our providers are licensed naturopathic physicians and mental health counselors led by Dr. Koichi Tanji, ND, LMHC. In Washington, controlled substances such as ADHD stimulants and benzodiazepines are outside naturopathic prescribing scope, so when one is part of the right plan we coordinate with your prescribing physician or nurse practitioner.

Good to know

Frequently asked questions

Can gut problems cause anxiety or depression?

The gut and brain influence each other in both directions. Digestive problems can worsen anxiety and mood, and stress can worsen digestion, so treating both together often works best.

Do you replace a gastroenterologist?

No. We coordinate with your primary care provider or gastroenterologist for medical evaluation and focus on the mind-body, nutrition and stress side of care.

Will I have to follow a strict diet?

Not usually. We focus on a varied, sustainable eating pattern and only use short, structured elimination approaches when there is a clear reason.

Is this available by telehealth?

Yes, anywhere in Washington, as well as in person in Bellevue.
