GI Issues or Food Sensitivity Testing

GI issues and food sensitivity testing are both important topics related to digestive health. Let’s explore them in more detail:

GI Issues:

Gastrointestinal (GI) issues refer to a wide range of problems that affect the digestive system, including the esophagus, stomach, small intestine, large intestine (colon), rectum, and anus. Common GI issues include:

Gastroesophageal reflux disease (GERD): A condition where stomach acid flows back into the esophagus, causing heartburn and discomfort.

Irritable bowel syndrome (IBS): A chronic disorder characterized by abdominal pain, bloating, changes in bowel habits (diarrhea or constipation), and often associated with sensitivity to certain foods.

Inflammatory bowel disease (IBD): An umbrella term for chronic conditions such as Crohn’s disease and ulcerative colitis, characterized by inflammation in the digestive tract leading to symptoms like abdominal pain, diarrhea, and weight loss.

Gastritis: Inflammation of the stomach lining, often causing symptoms like stomach pain, indigestion, nausea, and bloating.

Peptic ulcers: Open sores that develop on the lining of the stomach, upper small intestine, or esophagus, often resulting in abdominal pain, indigestion, and bloating.

The diagnosis and treatment of GI issues depend on the specific condition and its severity. Gastroenterologists conduct various tests, including blood work, endoscopy, colonoscopy, imaging studies, and stool tests, to determine the underlying cause of GI symptoms. However, this often leads to unanswered questions as to why these symptoms are present. 

Food Sensitivity Testing:

Food sensitivity testing is a diagnostic tool used to identify potential adverse reactions to specific foods. It aims to identify food intolerances or sensitivities that can trigger a variety of symptoms, such as gastrointestinal discomfort, bloating, diarrhea, skin rashes, headaches, fatigue, and more. However, it is important to note that food sensitivity testing is distinct from food allergies, which involve the immune system and can cause severe or life-threatening reactions.

There are various methods of food sensitivity testing, including:

Elimination diet: This involves removing potential trigger foods from the diet for a specific period and then reintroducing them gradually to monitor symptoms.

Blood tests: These tests measure immunoglobulin G (IgG) antibody levels in specific foods. However, the scientific validity of IgG-based testing for food sensitivities is debated, as elevated IgG levels may not necessarily indicate a true sensitivity or intolerance.

Skin prick tests: These tests involve pricking the skin and applying small amounts of allergenic foods to assess for an immediate allergic reaction. They are primarily used for diagnosing food allergies rather than food sensitivities.

Functional medicine tests: Some functional medicine practitioners offer specialized tests, such as IgG/IgA/IgM immunoglobulin testing, cytokine testing, or leukocyte activation testing (LAT).

It’s important to approach food sensitivity testing with caution. The reliability and accuracy of these tests can vary, and results should be interpreted in the context of clinical symptoms and medical guidance. Elimination diets, under the guidance of a healthcare professional, in combination with advanced lab testing, are often considered the gold standard for identifying food sensitivities.

Consultation and Follow-up:

In summary, GI issues encompass a wide range of conditions affecting the digestive system, while food sensitivity testing aims to identify potential adverse reactions to specific foods. Seeking medical advice from healthcare professionals, such as Crysty Frick, NP-C, is crucial for accurate diagnosis, appropriate treatment, and dietary management of GI issues and food sensitivities.
