Functional Medicine Insights from Merge Medical Center in Charleston
Many patients diagnosed with autoimmune conditions are surprised to learn that the health of their digestive system may play a critical role in their immune function.
Research increasingly shows that intestinal permeability, commonly referred to as “leaky gut,” may contribute to the development of autoimmune disease.
At Merge Medical Center, we help patients throughout the Charleston and Mount Pleasant area understand this important connection and work to restore gut health through a functional medicine approach.
What Is Leaky Gut?
The intestinal lining acts as a barrier that controls what enters the bloodstream.
When this barrier becomes damaged or inflamed, small gaps may form between intestinal cells. This allows substances such as food particles, toxins, and bacteria to enter the bloodstream.
When this occurs, the immune system may respond by producing inflammation.
Over time, this chronic immune activation can contribute to autoimmune conditions.

Conditions Associated with Leaky Gut
Research suggests that intestinal permeability may be linked to several autoimmune conditions, including:
- Celiac Disease
- Hashimoto’s Thyroiditis
- Type 1 Diabetes
- Rheumatoid Arthritis
While leaky gut is not the only cause of these conditions, improving gut health can be an important step in supporting immune balance.
Symptoms of Leaky Gut
Patients with intestinal permeability may experience symptoms such as:
- Chronic bloating
- Food sensitivities
- Digestive discomfort
- Fatigue
