Your IBS Specialist on Long Island Who Actually Gets It

ToggleHi, I'm Marina — and I know exactly how frustrating IBS can be.
After years of watching brilliant, driven women cycle through elimination diets, expensive supplements, and “just manage it” advice, I realized something:
That's why I founded IBS Dietitians with a different philosophy: your gut doesn't need more restrictions—it needs real restoration.

My Story: From Conventional to Life-Changing
As a Registered Dietitian Nutritionist, I started my career following the traditional playbook. Hand out food lists, recommend fiber supplements, tell people to “reduce stress.” But I kept seeing the same pattern: temporary relief followed by frustration when symptoms returned.
Everything changed when I discovered functional medicine and root-cause healing.
Instead of just managing IBS symptoms, I learned to restore the underlying functions that create lasting digestive health:
- Energy production at the cellular level
- Gut-brain communication that's often misfiring
- Microbiome balance that actually sticks
- Natural digestive movement that works like it should
The results? Women who hadn't felt normal in years were finally living without bathroom anxiety, bloating, and food fear.
The Moment Everything Changed
I'll never forget the exhausted mother of three who came to me after years of failed treatments. Despite all my training, she still wasn't getting better.
Watching her struggle to show up for her kids because of her gut issues broke something open in me. I realized my integrative training wasn't enough.
That's when I made a promise: I would go far beyond conventional approaches to find what actually works.
I dove deeper into functional medicine and root-cause restoration – determined that no mother would leave my practice still suffering.
She became my first major success with this new approach. Today, she's the energetic, present mom she always wanted to be.
Why IBS Dietitians is Different
We don't just manage symptoms — we restore function.
While other practitioners keep you trapped in elimination diets and endless protocols, we focus on what actually creates lasting change:
Personalized Assessment
Goes beyond basic food sensitivities to understand your unique IBS pattern and root causes
Root Cause Analysis
Discover what's really happening in your digestive system instead of just treating symptoms
Systematic Restoration
Target your gut's core functions: energy, nerve signaling, and natural movement
Clear Action Plans
Get specific, measurable steps with timelines—no more guessing what to do next
Long-term Freedom
Add foods back and trust your body again—no lifetime restrictions required
Our clients typically see improvement within 7-10 days because we target the actual dysfunction, not just the symptoms.
