If you are dealing with SIBO and feel stuck in cycles of bloating, restrictive diets, antibiotics, or symptoms that keep coming back, this is not a failure on your part.
In my work as a functional nutritionist, I help people with SIBO understand what is driving their digestive symptoms and support healing through personalized nutrition rather than one size fits all protocols.

As Seen in and Worked With:
Does This Sound Like You?
SIBO can present differently for each person, but many clients come to me because they are experiencing:
- Persistent bloating or abdominal discomfort
- Gas, constipation, diarrhea, or alternating bowel habits
- Food reactions that seem unpredictable
- Fatigue, brain fog, or low energy
- Weight gain or difficulty losing weight
- Anxiety around eating or fear of triggering symptoms
- Mood challenges such as depression and ruminating thoughts
You may have tried elimination diets, antimicrobials, or antibiotics with
temporary relief or no relief at all.
Often, that is because SIBO is not just a gut issue. It is influenced by digestion, motility,
nutrient status, stress physiology, and individual biochemistry.

Testimonials from Happy (and Healthy) Clients
I would like to thank Samantha Gilbert for her outstanding discernment and help over this past year. I came to her very tired, always napping, feeling weak, unbalanced (from having Muscular Dystrophy), finding myself sluggish most days and frequently dealing with migraines.
In addition to all this, my digestive system was a mess and had been for years.
Based on the test results and her vast knowledge of how the microbiome works, Samantha was able to put together a plan of action for me, including supplements and changes in diet.
Within less than six months, I was feeling better. My histamine level returned to a normal number. I was sleeping through the night, no longer napping, my digestive system had improved significantly, and I was no longer having migraines.
Not only this, but upon standing, I had had difficulties with balance issues. I noticed that my balance improved significantly. That was a surprise to the both of us!
All I can say is this, God bless you, Samantha. You know what you’re doing. If you are not feeling well, give Samantha’s expertise a try. You have to follow the plan. You must stick with the program that she creates in order for it to work. I believe you, too, will notice significant improvements.

For years, I’ve struggled with severe anxiety, depression, suicidal thoughts, eating disorders, alcoholism, poor sleep, and a variety of physical issues like stomach sensitivity, bloating, mucus and blood in my stool, low libido, and vaginal dryness.
Through detailed testing, Sami identified that I had chemical imbalances and a bacterial gut infection. Once we discovered these issues, she created a personalized protocol tailored specifically to my body’s needs. The change was incredible, I noticed improvements within weeks!
Now, six months later, I’ve seen so many positive changes. I’m no longer feeling depressed, my anxiety has greatly decreased, and I handle stress more effectively. I am not craving or dependent on alcohol, I enjoy eating clean and healthy food without feeling guilt, my focus has improved, and I no longer struggle with brain fog or scattered thoughts. My sleep quality has improved as well, no more tossing and turning from active dreams at night.
My digestive health has improved, my menstrual cycles are regular, my skin looks better, my nails are stronger, and my libido has returned to normal with no more dryness! Honestly, the list of positive changes could go on and on. I am so grateful for being introduced to Sami and for trusting her process and guidance.

How Nutrition Plays a Role in SIBO
From a functional nutrition perspective, SIBO (Small intestinal bacterial overgrowth) is rarely caused by one single factor. Symptoms are often influenced by deeper patterns such as:
Digestive Function and Motility
Low stomach acid, slowed motility, or impaired bile flow can allow bacteria to overgrow in the small intestine.
Nutrient Deficiencies
SIBO can interfere with absorption of key nutrients, which can worsen fatigue, mood changes, and digestive resilience.
Inflammation and Gut Integrity
Chronic irritation of the gut lining can increase sensitivity to foods and slow recovery.
Stress and Nervous System Load
The gut and nervous system are closely connected. Chronic stress can impair digestion and gut movement.
What Clients Often Notice Over Time
While every experience is different, clients commonly report:
-
Reduced bloating and digestive discomfort
-
Improved tolerance to foods
-
More stable energy and clearer thinking
-
Less anxiety around eating
-
A stronger sense of control over symptoms
There are no overnight fixes, but with the right support, progress becomes sustainable and lasting.
Is SIBO Treatment the Right Fit for You?
A Good Fit If:
- You want personalized nutrition support for SIBO
- You are tired of restrictive or rotating diets
- You want to understand what is happening in your gut
- You are open to gradual, realistic changes
Not a Good Fit If:
- You are looking for a quick fix
- You want medical diagnosis or prescriptions
- You are not open to adjusting food or lifestyle habits
- You are not willing to work through symptoms gradually as your gut heals
SIBO Nutrition Support: Common Questions
Here are answers to some frequently asked questions that may help if you need assistance or have any inquiries.
Is SIBO curable?
SIBO can improve significantly when the underlying causes are addressed. Many people relapse because treatment focuses only on killing bacteria. Nutrition support helps stabilize digestion, nutrient status, and gut function so progress is more sustainable.
Do you diagnose or medically treat SIBO?
No. I do not diagnose or prescribe. I provide nutrition therapy and education to support gut health. When appropriate, I work alongside your doctor or gastroenterologist to ensure care is safe and coordinated.
How can a SIBO nutritionist or dietitian actually help?
SIBO is rarely just about food avoidance. Nutrition support focuses on:
Reducing digestive stress without extreme restriction
Supporting motility, nutrient absorption, and blood sugar
Identifying patterns that contribute to recurrence, which helps many clients feel more stable and less reactive over time.
Do I need to follow a strict SIBO diet forever?
No. Long-term restriction often worsens symptoms and nutrient deficiencies. The goal is to use food strategically, then gradually expand your diet as your gut becomes more resilient.
Can SIBO affect weight, energy, or mood?
Yes. Many clients experience fatigue, brain fog, weight changes, OCD, and anxiety with SIBO. These symptoms are often linked to malabsorption, blood sugar swings, and inflammation rather than willpower or discipline.
Is this available if I don’t live in North Carolina?
Yes. All sessions are virtual. I work with clients across North Carolina, the United States, and internationally.
How long does it take to feel improvement?
Everyone is different. Some clients notice early improvements in digestion or energy, while others need gradual adjustments. The focus is steady progress, not quick promises.
How do I know if this approach is right for me?
The best next step is a free one-on-one consultation. We’ll talk through your symptoms, history, and goals to see if nutrition support makes sense for your situation.
