Gut Health & GI-MAP Testing
Struggling with bloating, brain fog, fatigue, or stubborn weight?
Your gut may be the missing link… and a GI-MAP stool test can show us why.
Gut health testing at Modern Endocrine in Oklahoma City uses the GI-MAP… an advanced, DNA-based stool test… to find the root cause of bloating, brain fog, fatigue, and stubborn weight instead of guessing.
Your gut microbiome influences nearly everything: digestion, metabolism, hormones, mood, and immune function.
Led by dual board-certified endocrinologist Dr. Cassie Smith… who wrote the book on the gut-hormone connection, Fix Your Gut Fix Your Hormones… our team reads your results and builds a targeted healing plan around them.
What does my gut have to do with how I feel?
More than almost anything else. Your gut microbiome helps regulate your hormones, metabolism, mood, sleep, energy, and immune system. When its balance is off, the effects show up all over your body… fatigue, weight gain, brain fog, irritability, and digestive distress. That’s why so many “unexplained” symptoms trace back to the gut.
Two-thirds of people have recurring symptoms like gas, bloating, constipation, or diarrhea and have come to accept them as normal. They’re common… but they’re not normal, and they’re worth investigating. When we look at your gut and your hormones together, we can finally connect the dots and treat the cause, not just the symptom.
What is the GI-MAP test
The GI-MAP is a functional stool test that uses DNA-based technology to give an ultra-precise look at your gut. Unlike standard stool tests, it measures the specific bacteria, pathogens, parasites, and markers driving your symptoms… so we can build a targeted healing plan instead of relying on trial and error.
The GI-MAP identifies:
-
Harmful bacteria and pathogens that trigger chronic inflammation and digestive distress
-
Parasites & yeast overgrowth disrupting gut balance and metabolism
-
Leaky gut markers that may contribute to food sensitivities, autoimmune conditions, and hormonal imbalances
-
Digestive enzyme function, to assess how well you absorb nutrients
-
Gut inflammation levels linked to IBS, SIBO, weight gain, and metabolic dysfunction
