5 most common digestive issues that are on the rise in the US (and how to tackle them)

Digestive health is one of the integral keys to overall healthy living because it allows the body to efficiently break down food and absorb vital nutrients, which are essential for energy, growth, and cell repair.

A healthy digestive system also plays a significant role in overall well-being, impacting everything from immunity and mental health to the prevention of various diseases.However, digestive health is increasingly in the spotlight as millions of Americans report bloating, pain, irregularity, and heartburn. Digestive issues don’t just cause uncomfortable symptoms – they can disrupt travel, social life, and even professional productivity.

40% of Americans say their daily lives are disrupted by digestive problems, says the American Gastroenterological Association.Understanding why these ailments are on the rise – and how to effectively manage them – is crucial for restoring wellness and enjoying daily life.

Let’s explore the top five issues and practical solutions to them.

Irritable Bowel Syndrome (IBS)

IBS affects an estimated 25–45 million Americans – about 10–15% of adults, with women disproportionately affected.

IBS has been increasingly recognized, partly due to widespread social media awareness. Characterized by abdominal pain, bloating, and irregular bowel habits, this functional disorder is on the rise, fueled by stress, diet, post-COVID gut dysfunction, and social media-driven self-diagnosis.

Symptoms include abdominal pain, bloating, and changes in bowel habits, ranging from constipation to diarrhea.

Why it's rising:

Heightened stress and anxiety post-pandemic, poor dietary trends and microbiome imbalance, and most importantly – greater self-diagnosis and clinical detection are likely to contribute to the rise of IBS.

How to tackle it:

Dietary shifts: A low‑FODMAP diet under professional guidance is first-line. It systematically eliminates and reintroduces fermentable carbs to identify triggers. Psyllium fiber especially benefits constipated individuals. 76% of patients see improvement after switching to this diet. Increase fiber intake for constipation-predominant IBS, while avoiding insoluble fiber if diarrhea is dominant.Stress management: Techniques like mindfulness, relaxation therapy, hypnotherapy, and CBT calm the gut‑brain axis.Lifestyle essentials: Regular exercise, adequate hydration, adequate sleep, and fiber-rich whole foods support healthy gut motility.

Gastroesophageal Reflux Disease (GERD)

About 20% of US adults experience GERD, which occurs when acid reflux causes bothersome symptoms at least twice weekly. The consequence? Heartburn and chest discomfort impact sleep, quality of life, and carry long-term risks if untreated. Chronic acid exposure may increase the risk of esophageal damage and even cancer.

Why it's rising:

Sedentary lifestyles, obesity, and diets rich in fatty, spicy, and processed foods are the contributing factors.

How to tackle it:

Lifestyle tweaks: Eat smaller meals, drop trigger foods/drinks like caffeine, alcohol, spicy and fatty foods, avoid eating within 2–3 hours before bedtime, and elevate your bed’s head by 6–8 inches.Weight control: Addressing obesity reduces reflux episodes substantially.Medication when needed: Use OTC antacids or acid blockers (H2 inhibitors or PPIs).

Persistent symptoms should prompt evaluation to prevent complications like esophagitis or Barrett’s esophagus.

Chronic Constipation

Constipation affects an estimated 63 million Americans, though surveys show nearly a third regularly feel constipated – often correlating with low fiber intake, dehydration, inactivity, and IBS. Constipation is on the rise due to low fiber consumption, poor hydration, reduced activity, and comorbid conditions like diabetes and IBS.

Only 5–9% meet the recommended fiber intake.

Why it's rising:

Poor hydration and fiber-poor, processed diets, and sedentary lifestyles are the main reasons.

How to tackle it:

Hydration: Aim for 2–3 L of water daily—roughly 47% of Americans under-hydrate.High‑fiber diet: Gradually increase soluble fiber (20–35 g/day) via grains, vegetables, legumes, fruits, and psyllium supplements.Routine and movement: Establish regular bathroom habits, avoid straining, and incorporate at least moderate physical activity.Realistic treatments: Use bulk-forming laxatives or osmotic agents if necessary – but consult a doctor if symptoms persist.

Inflammatory Bowel Disease (IBD: Crohn’s and Ulcerative Colitis)

IBD – comprising Crohn’s disease and ulcerative colitis – affects about 1.4–1.6 million Americans. These chronic inflammatory conditions cause serious symptoms, like abdominal pain, rectal bleeding, persistent diarrhea (often bloody), fatigue, and weight loss, and the incidence is rising.

Why it's rising:

Genetic susceptibility combined with Western diets, environmental triggers, and immune dysregulation are the main culprits behind the surge in this disease.

How to tackle it:

Prompt diagnosis: Persistent diarrhea, rectal bleeding, and pain require colonoscopy and lab testing.Medication regimens: Use anti-inflammatories, corticosteroids for flares, immunomodulators, and biologics to maintain remission. Surgery might be needed for complications.Nutrition strategies: During flares, low-residue diets help; dietitian-guided intake during remission prevents malnutrition.Ongoing monitoring: Regular check-ups reduce risks like stricture formation and colorectal cancer.

Celiac Disease

Around 1–2 million Americans are diagnosed with celiac disease, a serious autoimmune reaction to gluten. Many cases remain undiagnosed, with about 2.5 million people unknowingly affected and undiagnosed.

It damages the small intestine lining, impairs nutrient absorption, and leads to symptoms like diarrhea, bloating, anemia, and fatigue.

Why it's rising:

Improved testing and awareness, and possibly early-life dietary changes, might be the possible reasons behind the surge.

How to tackle it:

Accurate diagnosis: Requires blood tests for tTGA antibodies and a confirmatory duodenal biopsy.Strict gluten-free diet: Eliminating wheat, barley, and rye is essential – and working with a dietitian reduces the risk of nutritional deficiencies.Nutrient replacement: Monitor iron, folate, calcium, vitamin D, and consider supplements or fortified gluten-free grains.Lifelong compliance: Stay vigilant to avoid hidden gluten in cross-contaminated products.Digestive issues – IBS, GERD, chronic constipation, IBD, and celiac disease – are escalating in prevalence, fueled by modern lifestyles, stress, dietary patterns, and improved diagnosis, significantly impacting daily living.

But the narrative isn’t hopeless.Through scientifically backed dietary modifications, lifestyle adjustments, stress management, and medical care, you can take control. Early screening, persistent symptom tracking, and professional guidance help restore digestive comfort and well-being.
