Top 5 Digestive Health Issues and How Functional Medicine Tackles Them Naturally

Your digestive system is often called the “second brain” — and for good reason. It handles breaking down everything you eat, extracting vital nutrients, managing trillions of microbes (your gut microbiome), and sending signals that affect your immune system, hormones, and even your mood.

When your gut is unhealthy, you might notice symptoms like bloating, stomach pain, fatigue, or even brain fog and skin problems. These are not isolated issues but clues your body gives when the digestive system is out of balance.

Most conventional medicine focuses on treating symptoms — like popping antacids for heartburn or anti-diarrheal pills for upset stomach — but functional medicine takes a different path. It seeks to understand the root cause of the digestive issues and restore true health by optimizing digestion and healing the gut naturally.

Dr. Monica Bhardwaj, a renowned functional medicine practitioner, uses this approach to help patients regain their health holistically, by combining modern science with personalized, natural therapies.

The Top 5 Digestive Health Issues You Must Know About

1. Irritable Bowel Syndrome (IBS)

What is IBS?

IBS is a common digestive disorder characterized by a cluster of symptoms including abdominal cramping, bloating, and irregular bowel habits such as diarrhea, constipation, or both. It can significantly affect quality of life and is often misunderstood.

Why does IBS occur?

IBS is caused by multiple interlinked factors:

• Microbial imbalance: Your gut houses both helpful and harmful bacteria. In IBS, harmful bacteria or yeast may overgrow, upsetting digestion and causing gas and bloating.
  
• Food sensitivities: Many IBS sufferers react to specific fermentable carbs called FODMAPs (found in garlic, onions, wheat, apples), gluten, or dairy, leading to digestive upset.
  
• Gut-brain axis disruption: Stress and anxiety can worsen symptoms by altering gut motility and increasing pain perception.
  
• Low-grade inflammation: Inflammation in the gut lining may make the intestines hypersensitive.
  

How Dr. Monica Bhardwaj Tackles IBS:

• Comprehensive Testing: She uses stool and breath tests to pinpoint microbial imbalances, yeast overgrowth, or hidden infections causing IBS symptoms.
  
• Personalized Elimination Diets: She guides you to identify and remove foods that trigger symptoms, often starting with a low-FODMAP or gluten-free diet tailored to your body.
  
• Rebalancing the Microbiome: With targeted probiotics and prebiotics, she helps repopulate good bacteria and restore balance.
  
• Calming the Nervous System: Mind-body practices such as guided meditation, breathing exercises, and yoga are integrated to reduce stress and normalize gut-brain communication.
  
• Reducing Inflammation: Natural anti-inflammatory supplements like turmeric, ginger, and omega-3 fatty acids are recommended to soothe the gut lining.
  

Extra Practical Tips:

• Keep a detailed food and symptom diary to spot patterns and avoid triggers.
  
• Engage in gentle daily exercise like walking, which helps regulate bowel movements.
  
• Avoid caffeine, alcohol, and carbonated drinks to reduce gut irritation.
  

2. Gastroesophageal Reflux Disease (GERD)

What is GERD?

GERD is the condition where stomach acid flows back into the esophagus, causing symptoms like:

• Heartburn (a burning sensation behind the breastbone)
  
• Regurgitation of acid or food
  
• Hoarseness, chronic cough, or a sour taste in the mouth
  
• Difficulty swallowing or chest discomfort
  

Why does GERD happen?

The main cause is a weakened or dysfunctional lower esophageal sphincter (LES) — the muscle that acts as a valve between the stomach and esophagus. Factors contributing include:

• Poor LES function allows acid reflux.
  
• Delayed stomach emptying increases pressure, forcing acid upward.
  
• Lifestyle factors: obesity, smoking, overeating, or lying down right after meals can worsen reflux.
  
• Interestingly, many people with GERD have low stomach acid, which causes incomplete digestion and leads to reflux symptoms.
  

Dr. Monica’s Functional Medicine Approach to GERD:

• Assessing Stomach Acid Levels: Through specialized tests, she determines if you have low stomach acid, a key but often overlooked cause of reflux.
  
• Supporting Digestion: Using natural bitters, digestive enzymes, and apple cider vinegar to improve stomach acid production and digestion.
  
• Gut Lining Repair: Supplements like L-glutamine, zinc carnosine, and slippery elm soothe and protect the esophageal lining from acid damage.
  
• Lifestyle Coaching: Guidance on eating smaller meals, avoiding trigger foods (spicy, fatty, chocolate, caffeine), and sleeping with the head elevated to reduce reflux episodes.
  
• Stress Management: Incorporating relaxation techniques, as stress increases acid secretion and muscle tension.
  

Extra Practical Tips:

• Avoid eating at least 3 hours before bedtime to reduce reflux risk.
  
• Maintain a healthy weight to lower abdominal pressure on the stomach.
  
• Quit smoking and limit alcohol to protect your LES function.
  

3. Small Intestinal Bacterial Overgrowth (SIBO)

What is SIBO?

SIBO occurs when bacteria from the large intestine overgrow in the small intestine, where they are normally sparse. This causes:

• Excessive gas and bloating
  
• Abdominal discomfort
  
• Diarrhea, constipation, or alternating patterns
  
• Malabsorption of nutrients, leading to deficiencies and fatigue
  

Why does SIBO develop?

Several factors impair the small intestine’s natural defense:

• Low stomach acid: Allows bacteria to survive and multiply.
  
• Impaired gut motility: Slow movement means bacteria linger longer.
  
• Structural abnormalities: Surgeries, diverticula, or strictures can trap bacteria.
  
• Medication use: Proton pump inhibitors and antibiotics disturb the gut environment.
  

Dr. Monica’s Approach to SIBO:

• Diagnostic Breath Tests: Identifying whether hydrogen or methane-producing bacteria predominate helps tailor treatment.
  
• Herbal Antimicrobials: Natural agents like oregano oil, berberine, neem, and garlic selectively eliminate harmful bacteria while preserving beneficial ones.
  
• Improving Gut Motility: Using natural prokinetics like ginger, Iberogast, and magnesium to enhance intestinal clearing.
  
• Targeted Diets: Low-FODMAP or elemental diets reduce fermentable substrates feeding bacteria.
  
• Gut Healing: Post-treatment support with glutamine and probiotics to restore the gut lining and microbiome balance.
  

Extra Practical Tips:

• Avoid unnecessary antibiotics that can worsen dysbiosis.
  
• Gentle movement after meals promotes digestion and motility.
  
• Regular hydration keeps intestinal transit smooth.
  

4. Inflammatory Bowel Disease (IBD)

What is IBD?

IBD refers mainly to Crohn’s disease and ulcerative colitis, chronic conditions where the immune system attacks parts of the digestive tract, causing:

• Severe abdominal pain
  
• Persistent diarrhea, often bloody
  
• Weight loss and malnutrition
  
• Fatigue and anemia
  
• Risk of complications like strictures, abscesses, or colon cancer
  

Why does IBD develop?

IBD is complex and involves:

• Genetic susceptibility
  
• Immune system dysfunction, with chronic inflammation damaging the gut lining
  
• Microbiome imbalances exacerbating inflammation
  
• Environmental triggers such as smoking, stress, and diet
  

Dr. Monica’s Functional Medicine Strategy for IBD:

• Anti-inflammatory Nutrition: Diets rich in omega-3 fatty acids (fish, flaxseeds), antioxidant-packed fruits and vegetables, and avoidance of processed foods help modulate immune responses.
  
• Targeted Supplements: Curcumin, vitamin D, and probiotics to reduce inflammation and support gut flora.
  
• Gut Barrier Repair: Nutrients like collagen peptides, bone broth, zinc, and L-glutamine help rebuild the intestinal lining to reduce “leaky gut” and immune activation.
  
• Stress Reduction: Mindfulness, meditation, and other mind-body therapies lower flare-up risk by calming immune overactivity.
  
• Integrated Care: Working alongside specialists, Dr. Monica ensures your treatment plan is comprehensive and personalized.
  

Extra Practical Tips:

• Avoid sugar, processed foods, and artificial additives that trigger inflammation.
  
• Engage in moderate physical activity regularly to balance immune function.
  
• Prioritize good sleep for immune regulation.
  

5. Intestinal Infections

What are intestinal infections?

These are caused by harmful bacteria, viruses, or parasites invading your gut, resulting in symptoms like:

• Sudden diarrhea
  
• Abdominal cramps
  
• Nausea and vomiting
  
• Fever and dehydration
  

Why do intestinal infections happen?
Common causes include:

• Contaminated food or water
  
• Poor hygiene or travel to high-risk areas
  
• Weakened immune defenses
  

Dr. Monica’s Functional Medicine Approach:

• Natural Antimicrobials: Herbal remedies such as garlic, neem, oregano oil, and goldenseal target pathogens effectively without wiping out healthy bacteria.
  
• Hydration Support: Using electrolyte-rich fluids to prevent dehydration during illness.
  
• Microbiome Restoration: Probiotic supplementation and prebiotic foods help re-establish beneficial gut flora after infection.
  
• Gut Lining Healing: Nutrients like zinc and L-glutamine repair damage to the intestinal walls and reduce permeability.
  
• Immune Support: Nutritional guidance to strengthen immunity and speed recovery.
  

Extra Practical Tips:

• Always wash hands thoroughly and avoid risky foods when traveling.
  
• Rest sufficiently to help your immune system fight off infection.
  
• Practice safe food handling at home.
