What is Malabsorption?

Malabsorption is a condition in which the body is unable to properly absorb nutrients from food, leading to deficiencies in vitamins, minerals, fats, proteins, and carbohydrates. This condition can result in a wide range of symptoms, from digestive distress to systemic issues such as fatigue, neurological dysfunction, and weakened immunity.

Functional medicine views malabsorption as a symptom of deeper imbalances in the gut and systemic health. Identifying and addressing the root causes—whether they stem from gut dysbiosis, enzyme deficiencies, infections, or food sensitivities—is essential for long-term healing.

Symptoms of Malabsorption

Malabsorption can present with a variety of symptoms, which often overlap with other gastrointestinal and systemic conditions. Common signs include:

• Digestive Issues: Bloating, gas, diarrhea, constipation, or foul-smelling stools
• Nutrient Deficiencies: Low levels of iron, B12, vitamin D, zinc, magnesium, and fat-soluble vitamins (A, D, E, K)
• Weight Loss or Failure to Gain Weight: Despite adequate caloric intake
• Fatigue and Brain Fog: Due to poor absorption of essential nutrients
• Skin Conditions: Dry skin, eczema, acne, or dermatitis
• Weakened Immunity: Frequent infections and slow wound healing
• Neurological Symptoms: Nerve pain, tingling, depression, or cognitive decline
• Joint and Muscle Pain: Linked to inflammation and nutrient depletion

Common Causes of Malabsorption in Functional Medicine

1. Gut Dysbiosis and Microbiome Imbalance
• An overgrowth of harmful bacteria, yeast (e.g., Candida), or parasites can damage the intestinal lining and impair nutrient absorption.
• Insufficient beneficial bacteria reduce the production of enzymes needed for digestion.
2. Leaky Gut Syndrome (Intestinal Permeability)
• When the gut lining is compromised, undigested food particles and toxins enter the bloodstream, triggering inflammation and impairing nutrient absorption.
• Chronic stress, infections, and a poor diet contribute to this condition.
3. Enzyme and Bile Deficiency
• Pancreatic Insufficiency: The pancreas produces digestive enzymes (lipase, protease, amylase), and any dysfunction (e.g., due to chronic pancreatitis or gallbladder removal) can lead to fat and protein malabsorption.
• Bile Acid Deficiency: Bile from the liver is necessary for fat digestion, and any liver or gallbladder dysfunction can impact absorption.
4. Celiac Disease and Gluten Sensitivity
• Gluten-induced damage to the small intestine reduces the absorption of iron, calcium, folate, and other nutrients.
• Even non-celiac gluten sensitivity can contribute to malabsorption.
5. Inflammatory Bowel Disease (IBD) – Crohn’s & Ulcerative Colitis
• Chronic inflammation damages the intestinal lining, impairing nutrient absorption and leading to deficiencies in B12, iron, and fat-soluble vitamins.
6. Small Intestinal Bacterial Overgrowth (SIBO)
• Excess bacteria in the small intestine ferment carbohydrates before absorption, leading to bloating, gas, and nutrient deficiencies.
• SIBO is often associated with IBS, chronic stress, and motility issues.
7. Food Sensitivities and Allergies
• Reactions to dairy, gluten, soy, eggs, and processed foods can cause inflammation and damage the gut lining.
• Identifying and eliminating trigger foods can significantly improve nutrient absorption.
8. Chronic Stress and Hormonal Imbalances
• Chronic stress weakens digestion by reducing stomach acid and enzyme production, leading to poor nutrient breakdown and absorption.
• Cortisol imbalances can also disrupt gut motility and microbiome balance.
9. Medications that Impair Digestion
• Long-term use of proton pump inhibitors (PPIs), antibiotics, NSAIDs, and steroids can negatively impact gut health and nutrient absorption.

Functional Medicine Testing for Malabsorption

Functional medicine employs advanced testing to identify specific causes of malabsorption:

1. Comprehensive Stool Analysis
• Assesses gut bacteria, yeast overgrowth, parasites, inflammation markers, and enzyme levels.
2. SIBO Breath Test
• Identifies bacterial overgrowth in the small intestine affecting carbohydrate absorption.
3. Food Sensitivity Testing
• Helps identify immune-mediated reactions contributing to gut inflammation.
4. Organic Acids Test (OAT)
• Evaluates microbial imbalances, detoxification pathways, and vitamin deficiencies.
5. Blood Tests for Nutrient Deficiencies
• Measures B12, iron, folate, magnesium, vitamin D, zinc, and essential amino acids.
6. Hydrochloric Acid (HCl) Challenge Test
• Assesses stomach acid levels, crucial for breaking down proteins and minerals.

A Functional Medicine Approach to Healing Malabsorption

1. Optimizing Digestion and Nutrient Absorption

• Digestive Enzymes & Betaine HCl: Support stomach acid and enzyme production.
• Bile Support: Ox bile or dandelion root aids in fat digestion.
• Probiotics & Prebiotics: Replenish beneficial gut bacteria for improved microbiome balance.
• Bone Broth & Collagen: Help heal the intestinal lining and restore gut integrity.

2. Repairing the Gut Lining and Reducing Inflammation

• Glutamine: Supports gut lining repair and intestinal cell regeneration.
• Aloe Vera & Slippery Elm: Soothe the gut and reduce inflammation.
• Curcumin & Omega-3s: Help lower gut inflammation and improve immune function.

3. Addressing Underlying Infections and Dysbiosis

• Herbal Antimicrobials: Berberine, oregano oil, and garlic target bacterial overgrowth and Candida.
• Anti-Parasitic Protocols: Target hidden parasites affecting absorption.

4. Targeted Nutrient Repletion

• Intravenous (IV) Nutrient Therapy: Effective for severe deficiencies.
• Liposomal Supplements: Enhance absorption of B12, magnesium, and fat-soluble vitamins.
• Whole-Food-Based Supplements: Improve bioavailability.

5. Balancing the Nervous System and Reducing Stress

• Mindfulness & Meditation: Reduce stress-related gut dysfunction.
• Gentle Exercise (Yoga, Walking): Supports gut motility.
• Adequate Sleep: Essential for gut repair and immune regulation.

6. Personalized Nutrition Plan

• Elimination Diet: Identifies food triggers contributing to inflammation.
• Whole-Food, Anti-Inflammatory Diet: Focus on organic vegetables, quality proteins, and healthy fats.
• Small, Frequent Meals: Reduce digestive burden and improve absorption.

Preventing Relapses: Long-Term Gut Health Strategies

• Regular Probiotic Use: Supports a balanced microbiome.
• Rotate Foods: Prevents sensitivity development and promotes gut diversity.
• Periodic Functional Testing: Ensures ongoing nutrient optimization.
• Maintain Stress Management Practices: To protect gut function.

When to Seek Functional Medicine Guidance

If you are experiencing symptoms of malabsorption, working with a functional medicine practitioner can help identify root causes and develop a personalized healing plan. Addressing underlying digestive dysfunction is key to restoring optimal nutrient absorption and overall health.

Conclusion

Malabsorption is often a symptom of deeper gut imbalances that require a comprehensive, root-cause approach to healing. Functional medicine focuses on restoring digestion, repairing the gut lining, eliminating infections, and repleting nutrient deficiencies to help individuals achieve long-term health and vitality. By addressing these issues holistically, patients can prevent chronic disease and optimize their well-being.
