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.

Warning! This common digestive issue could signal a hidden cancer risk; doctors explain when to act
Oesophageal cancer, often stealthy and lethal, ranks among the top ten cancers globally. Early symptoms are easily mistaken for common digestive issues, leading to late diagnoses and reduced survival rates. Chronic acid reflux, or GERD, is a significant risk factor, potentially causing Barrett's oesophagus, a precursor to cancer. Oesophageal cancer ranks as the tenth most common cancer worldwide and remains one of the most lethal due to its stealthy progression and low survival rates. Often undetected until it reaches advanced stages, this cancer affects the oesophagus, the muscular tube that connects the throat to the stomach. One of the core challenges lies in its early presentation: symptoms are either minimal or mistaken for common digestive issues, allowing the disease to progress unnoticed. According to the Cleveland Clinic, early-stage oesophageal cancer typically does not cause significant symptoms, resulting in delayed diagnosis and reduced treatment options. A study published in 2017 highlighted that nearly 90 per cent of patients diagnosed with this cancer do not survive beyond a decade, emphasising the need for better awareness and early detection. The link between chronic acid reflux, or gastroesophageal reflux disease (GERD), and oesophageal cancer is becoming more evident. As ongoing research sheds light on subtle warning signs, medical experts stress the importance of not ignoring recurring digestive symptoms. What is oesophageal cancer? Oesophageal cancer originates in the inner lining of the oesophagus. There are two main types: adenocarcinoma, more common in Western countries and typically associated with chronic acid reflux and obesity, and squamous cell carcinoma, which is more prevalent globally and often linked to smoking and alcohol use. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Free P2,000 GCash eGift UnionBank Credit Card Apply Now Undo Both types interfere with the oesophagus's ability to carry food and liquids from the throat to the stomach. The cancer tends to develop slowly but progresses aggressively once symptoms become apparent. Unfortunately, by the time a diagnosis is made, the disease often has spread to nearby tissues or organs. The role of chronic acid reflux in cancer development Gastroesophageal reflux disease, or GERD, occurs when stomach acid flows back into the oesophagus, irritating its lining. While many individuals experience occasional acid reflux, persistent symptoms may indicate chronic GERD. The Cleveland Clinic notes that long-term exposure to stomach acid can lead to inflammation, cellular damage, and eventually a condition called Barrett's oesophagus. Barrett's oesophagus is characterised by abnormal changes in the oesophageal lining and is considered a precursor to oesophageal adenocarcinoma. Dr. Wendi LeBrett, a gastroenterology expert, has drawn attention to the subtle and often overlooked symptoms of acid reflux that may signal a deeper issue. She states that although heartburn is a common sign, not all individuals with GERD experience this symptom. In fact, as many as one in three people with acid reflux may have no noticeable heartburn at all. Unusual warning signs: What to watch for According to recent findings shared by Dr. LeBrett, several lesser-known symptoms could point to chronic acid reflux and potentially early oesophageal cancer. These include: Persistent nighttime coughing caused by acid entering the respiratory tract Breathing difficulties linked to airway irritation Worsening asthma symptoms Difficulty swallowing, especially with dry or solid foods Unexpected dental issues, including yellowing teeth, cracks, and enamel erosion These symptoms are frequently dismissed as isolated issues. However, recurring patterns—especially when accompanied by typical digestive discomfort—warrant medical evaluation. The risk of ignoring acid reflux Chronic acid reflux is not just an inconvenience. The Cleveland Clinic emphasises that repeated acid exposure can create lasting damage in the oesophagus, particularly if untreated. Long-term inflammation can lead to cellular changes that increase cancer risk. Barrett's oesophagus, for instance, is often silent but significantly heightens the chance of developing oesophageal cancer over time. Healthcare providers recommend not only treating GERD symptoms but also monitoring for potential complications. This includes routine screenings for patients with longstanding reflux, especially those over 50, those with obesity, or a history of smoking. Importance of early detection Due to the asymptomatic nature of early-stage oesophageal cancer, many patients are only diagnosed when the cancer is already advanced. At this point, treatment options are limited, and outcomes tend to be poor. Data published in the World Journal of Gastroenterology reinforces that five-year survival rates drop drastically as the disease progresses beyond the oesophagus. The importance of early detection is further underscored by the benefits of timely intervention. If identified early, oesophageal cancer can be managed with less invasive procedures, increasing survival chances. Endoscopic therapies and surgical resection, when performed before metastasis, can significantly improve outcomes. Why dental visits matter in oesophageal cancer Dentists may play a surprising role in early detection. Acid reflux can damage the teeth through enamel erosion, a condition often spotted during routine dental check-ups. Yellowing, increased sensitivity, and cracking may not seem connected to cancer risk, but could be early clues pointing to chronic acid reflux. When such signs are combined with other symptoms, they can prompt timely medical referrals and further testing. What experts recommend According to The Economic Times report, medical professionals emphasise vigilance when it comes to persistent digestive symptoms. Individuals experiencing chronic heartburn, cough, or swallowing difficulties should consult a physician for proper assessment. In some cases, an upper endoscopy may be recommended to visualise the oesophagus and detect abnormal changes. The American Gastroenterological Association also advises patients with known risk factors—such as obesity, male gender, smoking, and a family history of oesophageal cancer—to undergo regular screenings, especially if GERD symptoms persist beyond a few weeks despite treatment.

US Supreme Court tosses rulings that favored transgender people
Washington: The U.S. Supreme Court threw out on Monday judicial decisions that favored transgender people in cases from North Carolina, West Virginia, Idaho and Oklahoma, including in legal challenges to state health insurance programs that deny coverage for patients seeking gender-affirming medical treatment. Acting in appeals by officials in North Carolina and West Virginia, the justices ordered lower courts to reconsider their decisions siding with the challengers to the insurance policies in light of the Supreme Court's major June 18 ruling that upheld a Republican-backed ban in Tennessee on treatments such as puberty blockers and hormones for minors experiencing gender dysphoria. The Supreme Court decided that Tennessee's ban on youth transgender care did not violate the U.S. Constitution's 14th Amendment promise of equal protection, as challengers to the law had argued. The court's conservative justices were in the majority and liberal justices in dissent in the 6-3 decision. Gender dysphoria is the clinical diagnosis for significant distress that can result from an incongruence between a person's gender identity and the sex assigned at birth. The Supreme Court routinely orders lower courts to revisit certain cases that were on appeal in order to apply new case standards and legal interpretations from the nation's top judicial body. The case from North Carolina involved the state employee health plan, which excludes medical and surgical treatment "leading to or in connection with sex changes or modifications and related care." In West Virginia, Medicaid - the state-federal health insurance program covering low-income Americans - has denied coverage for "transsexual surgery" since 2004. Medicaid is managed primarily by state governments. In a similar case, the Supreme Court on Monday ordered reconsideration of a lower court's ruling that allowed a lawsuit to proceed against an Idaho official accused of denying surgical care to transgender Medicaid beneficiaries in that state, also taking into account the June 18 ruling. The justices also ordered reconsideration in a lower court's decision that revived a lawsuit challenging Oklahoma's policy barring transgender people from changing their birth certificates to match their gender identity. As in the Tennessee dispute, the plaintiffs had asserted that the policies violate the 14th Amendment and other laws. The justices did not immediately act in three other pending appeals involving state laws in West Virginia, Idaho and Arizona that would ban transgender athletes from female sports teams at public schools. Thursday is the next day when the Supreme Court acts on whether or not to take up pending appeals. The issue of transgender rights is a flashpoint in the U.S. culture wars. President Donald Trump during his 2024 election campaign promised to impose restrictions on gender-affirming care and sports participation, and since returning to office in January has taken aim at transgender rights. The Supreme Court in May permitted Trump's administration to implement his ban on transgender people in the U.S. military. Trump also has signed an executive order targeting what he called "gender ideology" and declaring that the federal government would recognize only two sexes: male and female. Trump also rescinded orders by his predecessor, Democrat Joe Biden, combating discrimination against gay and transgender people. The Supreme Court's ruling in the Tennessee case could bolster efforts by states to defend other measures targeting transgender people. Tennessee's law, passed in 2023, aimed to encourage minors to "appreciate their sex" by prohibiting healthcare workers from prescribing puberty blockers and hormones to help them live as "a purported identity inconsistent with the minor's sex." The Supreme Court's ruling, written by Chief Justice John Roberts, highlighted the "ongoing debate among medical experts regarding the risks and benefits associated with administering puberty blockers and hormones," and found that the state law directly responds to that uncertainty. The ruling, however, left some room for future legal challenges and for lower courts to apply tougher legal scrutiny and potentially find unlawful discrimination involving other curbs on transgender rights.

Is identity a valid ground for discharge? Hundreds of trans women in the US military face exit after new executive order
Thousands of transgender women in the US military are now packing up barracks, as President Donald Trump's new executive order effectively bans transgender people from serving in the military. Tired of too many ads? go ad free now Official Pentagon figures place the current number of transgender service members at roughly 4,200, though independent estimates suggest the figure could be closer to 10,000. According to the new order, a history or diagnosis of gender dysphoria is deemed 'incompatible with the high mental and physical standards necessary for military service'. The directive argues that 'the Armed Forces have been afflicted with radical gender ideology' and claims the new standards will ensure personnel are 'free of medical conditions or physical defects that may reasonably be expected to require excessive time lost from duty for necessary treatment or hospitalization.' It further asserts that 'a man's assertion that he is a woman … is not consistent with the humility and selflessness required of a service member. ' According to a Gallup survey in February 2025, only 58 percent of Americans supported allowing openly transgender personnel to serve, down from 71 percent in 2019 and 66 percent in 2021. Policy on transgender service members has shifted repeatedly over the past decade. The Obama administration lifted the longstanding ban in 2016, permitting access to gender‑related medical care. President Trump's first‑term order in 2017 re‑imposed restrictions on new recruits, though it left some exceptions for those already in uniform. President Joe Biden overturned that policy in 2021, restoring the right to serve. The 2025 order now removes virtually all exceptions and directs bases to begin separation proceedings against personnel diagnosed with gender dysphoria. A federal judge initially blocked the latest ban, citing possible constitutional violations, but the US Supreme Court lifted that injunction in April, allowing the policy to proceed while litigation continues. Tired of too many ads? go ad free now The Pentagon states that affected service members remain eligible for benefits, including separation pay, higher for those opting for a voluntary exit. Shift in political leadership has cast a shadow on the lives and careers of transgender women in the US military which remains suspended in uncertainty. Many who have dedicated years to service now face involuntary discharge, unclear benefit entitlements, and the emotional toll of being forced out not for performance, but for identity.
