Hiatus Hernia Diet — Foods to Eat and Avoid

Understanding Hiatus Hernia and Its Dietary Impact

A hiatus hernia occurs when a portion of the stomach pushes up through the diaphragm's opening (hiatus) into the chest cavity [1]. While many individuals experience no symptoms, others contend with persistent heartburn, regurgitation, and chest discomfort. The anatomical change associated with a hiatus hernia can weaken the lower oesophageal sphincter (LES), making it easier for stomach acid to flow back into the oesophagus [1]. This reflux is often exacerbated by certain foods and eating habits, highlighting the critical role of a well-managed hiatus hernia diet in symptom control.

Dietary choices directly influence the acidity of stomach contents and the pressure within the abdomen, both of which can impact hiatus hernia symptoms. Foods that are highly acidic, fatty, or gas-producing can trigger or worsen reflux, leading to significant discomfort. Conversely, a diet rich in low-acid, easily digestible foods can help soothe the digestive system and reduce the frequency and severity of symptoms [2].

Foods to Embrace: Your Hiatus Hernia Friendly Plate

Adopting a diet focused on gentle, nutrient-dense foods can significantly improve the comfort of individuals with a hiatus hernia. Prioritising lean proteins, non-citrus fruits, and a variety of vegetables and whole grains forms the foundation of a supportive hiatus hernia diet.

• Lean Proteins: Opt for easily digestible protein sources such as skinless chicken, turkey, fish, and lean cuts of beef or pork. These provide essential nutrients without contributing to excessive stomach acid production or delayed gastric emptying, which can worsen reflux [2].
• Non-Citrus Fruits: While citrus fruits are often problematic due to their high acidity, many other fruits are excellent choices. Bananas, apples, pears, melons, and berries are generally well-tolerated and provide valuable vitamins, minerals, and fibre [1].
• Vegetables: A wide array of vegetables can be included in a hiatus hernia diet. Green beans, peas, carrots, broccoli, leafy greens like spinach and kale, and sweet potatoes are all good options. Cooking vegetables thoroughly can make them even easier to digest [2].
• Whole Grains: Complex carbohydrates from whole grains are beneficial. Oatmeal, bran cereal, brown rice, whole-wheat bread, pasta, and crackers offer fibre and sustained energy without irritating the digestive tract. These can also help absorb stomach acid [1].
• Healthy Fats: While excessive fats should be limited, healthy fats in moderation are important. Sources like avocado, olive oil, and nut and seed oils can be incorporated carefully. It's crucial to avoid large quantities of fat, as they can slow digestion and increase reflux risk.
• Low-Fat Dairy Alternatives: Traditional dairy products, especially full-fat versions, can sometimes trigger symptoms. Consider low-fat or skim milk, low-fat yoghurt, fat-free cheeses, and plant-based alternatives like soy milk as gentler options [1].
• Water: Staying well-hydrated is paramount. Water helps dilute stomach acid and aids in digestion. It's best to sip water throughout the day rather than consuming large quantities during meals, which can distend the stomach.

Foods to Avoid: Triggering Symptoms

Identifying and eliminating trigger foods is a cornerstone of managing hiatus hernia symptoms. Certain foods and beverages are notorious for exacerbating heartburn and reflux by increasing stomach acidity or relaxing the LES [3].

• Acidic Foods: High-acid foods are frequent culprits. This includes citrus fruits and their juices (oranges, grapefruits, lemons, cranberry juice) and tomatoes and tomato-based products such as spaghetti sauce, pizza, and chili. These can directly irritate the oesophageal lining [3].
• Fatty and Fried Foods: Foods high in fat, whether fried chicken, fatty meats, or rich desserts, can significantly delay stomach emptying. This prolonged presence of food in the stomach increases the likelihood of acid reflux. High-fat dairy products like whole milk, ice cream, and creamed foods, as well as excessive butter and oils, should also be limited [3].
• Spicy Foods: Dishes with a high spice content, including those with chilli or excessive pepper, can irritate the oesophagus and stomach, leading to increased discomfort and heartburn [3].
• Caffeine and Alcohol: Both caffeine (found in coffee and tea, even decaffeinated versions) and alcoholic beverages can relax the LES, allowing stomach acid to reflux more easily. It is advisable to significantly reduce or eliminate their consumption [3].
• Carbonated Beverages: Fizzy drinks like sodas and sparkling water introduce gas into the stomach, which can increase pressure and promote reflux. Opt for still water or herbal teas instead [3].
• Mint: Peppermint and spearmint, often found in teas or candies, are known to relax the LES and can worsen reflux symptoms [3].
• Garlic and Onions: While healthy for many, garlic and onions can be problematic for some individuals with hiatus hernia, potentially triggering heartburn and discomfort [3].
• Chocolate: This beloved treat can also relax the LES, making it a common trigger for reflux symptoms in susceptible individuals [3].

Smart Eating Habits and Lifestyle Adjustments

Beyond specific food choices, how and when you eat can profoundly impact hiatus hernia symptoms. Incorporating smart eating habits and making certain lifestyle adjustments can provide additional relief.

• Eat Smaller, More Frequent Meals: Instead of three large meals, opt for five to six smaller meals throughout the day. This prevents the stomach from becoming overly full, reducing pressure on the LES [2].
• Avoid Eating Close to Bedtime: Finish your last meal at least two to three hours before lying down. This allows ample time for digestion and stomach emptying, minimising the risk of nocturnal reflux [2].
• Stay Upright After Meals: Gravity is your friend. Remaining upright for a few hours after eating helps keep stomach contents where they belong [2].
• Chew Food Thoroughly: Proper chewing aids digestion and reduces the workload on your stomach.
• Avoid Overeating: Listen to your body's hunger and fullness cues to prevent overfilling your stomach.
• Maintain a Healthy Weight: Excess abdominal weight can put additional pressure on the stomach and diaphragm, worsening hiatus hernia symptoms. Weight management can significantly improve comfort [2].
• Wear Loose-Fitting Clothing: Tight clothing around the waist can compress the abdomen, increasing pressure and potentially triggering reflux.
• Elevate the Head of Your Bed: Raising the head of your bed by 6 to 8 inches using blocks (not just extra pillows) can help prevent stomach acid from flowing back into the oesophagus while you sleep [2].
• Quit Smoking: Smoking weakens the LES and increases stomach acid production, making it a significant contributor to reflux symptoms. Quitting can offer substantial relief [2].
