October 11, 2025 •

4 min read

The gastrointestinal (GI) tract is the second most frequently affected system in people with scleroderma, impacting comfort, limiting food choices, and reducing quality of life. Learning what foods aggravate scleroderma is a crucial step toward proactive symptom management and improved digestive health.

Quick Summary

This article explores common dietary triggers for scleroderma symptoms, focusing on foods that can worsen acid reflux, bloating, and inflammation. It covers how processed foods, high sugar intake, and specific types of carbohydrates can impact gut health. The guide offers practical strategies for dietary modifications and highlights the benefits of approaches like the low FODMAP and elimination diets.

Key Points

Identify Personal Triggers: Keep a food and symptom diary to track specific foods that aggravate your unique scleroderma symptoms, which can vary widely among individuals.
Reduce High-FODMAP Foods: For bloating and gas, consider a low FODMAP diet under a doctor's supervision to identify sensitivities to fermentable carbohydrates found in dairy, wheat, legumes, and certain fruits and vegetables.
Avoid Reflux-Causing Foods: Limit or eliminate acidic foods (citrus, tomatoes), spicy ingredients, high-fat meals, caffeine, alcohol, and chocolate to help manage heartburn.
Minimize Inflammation with Whole Foods: Ultra-processed foods, added sugars, and poor-quality fats can increase systemic inflammation; prioritize anti-inflammatory foods like fatty fish, olive oil, nuts, and brightly colored vegetables.
Adapt for Swallowing Issues: If dysphagia is a problem, modify food texture by pureeing, blending, or mincing, and avoid dry or sticky items. Warm liquids may also help with Raynaud's symptoms.
Consider Professional Guidance: Due to the risk of malnutrition and nutrient deficiencies, work with a registered dietitian specializing in autoimmune conditions to safely navigate dietary changes.
Stay Hydrated and Eat Small Meals: Drinking plenty of fluids and having small, frequent meals can help with digestion, nutrient absorption, and weight management.

Scleroderma, a chronic autoimmune disease, often causes a wide range of gastrointestinal complications, from acid reflux and bloating to difficulty swallowing. While there is no single 'scleroderma diet', many individuals find significant relief by identifying and avoiding specific dietary triggers that exacerbate their symptoms. The following guide outlines common food culprits and offers strategies to create a more gut-friendly eating plan.

Foods that Trigger Acid Reflux and Heartburn

Acid reflux is a common and often painful symptom for many people with scleroderma, caused by a weakened lower esophageal sphincter. Avoiding certain foods and beverages can help minimize the burning sensation and irritation. Key triggers include:

Fatty and Fried Foods: High-fat foods can relax the esophageal sphincter, allowing stomach acid to flow back up. This includes greasy fried foods, rich sauces, and some types of red meat.
Acidic Foods and Beverages: Citrus fruits (oranges, lemons), tomatoes, and tomato-based products are highly acidic and can irritate an already sensitive esophagus. Vinegar is another common culprit.
Caffeinated and Carbonated Drinks: Coffee, sodas, and other carbonated beverages can increase stomach acid production and pressure, triggering reflux.
Spicy Foods and Strong Flavors: Hot spices like chili, mustard, and pepper can irritate the lining of the esophagus. Raw garlic, onions, and mint are also frequently reported triggers.
Chocolate and Alcohol: Both chocolate and alcohol can relax the esophageal sphincter and trigger reflux.

Understanding FODMAPs for Bloating and Gas

FODMAPs are fermentable carbohydrates that are poorly absorbed in the small intestine and can cause uncomfortable bloating, gas, and abdominal pain in many people with scleroderma. An elimination diet focusing on low-FODMAP foods can help identify specific sensitivities. High-FODMAP foods to consider limiting or avoiding include:

Dairy Products: Lactose, a disaccharide, can be hard to digest. This includes milk, yogurt, and ice cream. Lactose-free alternatives or plant-based milks may be better tolerated.
Wheat-Based Products: Wheat contains fructans, a type of oligosaccharide that can cause GI distress. Many people find relief switching to gluten-free grains like rice, oats, or quinoa.
Legumes: Beans and lentils contain galacto-oligosaccharides and can be difficult to digest, leading to gas and bloating. Soaking and sprouting legumes may improve tolerance.
Certain Vegetables: Onions, garlic, asparagus, and artichokes are some common vegetables high in FODMAPs. Raw vegetables can be particularly problematic.
Specific Fruits: Apples, pears, peaches, and cherries contain excess fructose and polyols that can trigger GI symptoms.

General Inflammatory and Hard-to-Digest Foods

Beyond specific GI symptoms, certain foods can contribute to systemic inflammation and overall discomfort. Focusing on whole, unprocessed foods is a key strategy for managing scleroderma.

Ultra-Processed Foods: Pre-packaged baked goods, instant noodles, deli meats, and sugary beverages often contain additives that can negatively affect gut bacteria and increase inflammation.
Added Sugars: High consumption of added sugars has been linked to increased inflammation and a reduced diversity of beneficial gut bacteria. Look for hidden sugars on ingredient lists, such as sucrose, fructose, and corn syrup.
Poor-Quality Fats: Trans fats found in margarine and some processed foods should be avoided. Minimizing other seed oils like safflower and sunflower oil is also recommended.

Identifying Your Personal Triggers

Since dietary triggers can be highly individual, a systematic approach is often the most effective way to identify which foods aggravate your specific scleroderma symptoms. Working with a registered dietitian is recommended to ensure nutritional needs are met, especially during a restrictive diet.

Keep a Food Diary: Track everything you eat and drink, noting any physical symptoms that follow. This helps establish patterns and connections.
Trial an Elimination Diet: With medical guidance, remove common trigger categories (like dairy, gluten, or high-FODMAP foods) for a set period. Gradually reintroduce them one by one to see which ones cause a reaction.
Prioritize Nutrient-Dense Foods: Focus on anti-inflammatory whole foods like fatty fish (rich in omega-3s), colorful fruits and vegetables (antioxidants), nuts, and seeds.

Comparison of Potentially Aggravating vs. Supportive Foods


Symptom	Potentially Aggravating Foods	Supportive Alternatives
Acid Reflux	Citrus fruits, tomatoes, spicy foods, high-fat/fried foods, coffee, alcohol, chocolate	Bananas, melons, herbal teas (fennel, ginger), chamomile tea, lean proteins, steamed vegetables
Bloating/Gas	Dairy products, wheat, beans, lentils, onions, garlic, asparagus, specific fruits (apples, pears)	Lactose-free dairy or plant-based milks, gluten-free grains (oats, quinoa), well-tolerated fruits and vegetables, probiotics
Inflammation	Ultra-processed foods, added sugars, trans fats, refined carbohydrates, some red meats	Fatty fish (salmon), nuts, seeds, avocados, extra virgin olive oil, dark leafy greens, berries
Difficulty Swallowing	Dry foods (bread, toast), sticky foods (peanut butter, caramel), some raw vegetables	Smoothies, pureed vegetables, soups, stews, moist or minced proteins, using sauces/gravies to lubricate
Raynaud's	Cold foods and beverages, especially in cold weather	Warm liquids like soups and teas throughout the day

Conclusion: Personalizing Your Plate

Managing scleroderma through diet is a personalized journey, not a one-size-fits-all solution. While no diet can cure the condition, avoiding common triggers that aggravate gastrointestinal and inflammatory symptoms can lead to significant improvements in quality of life. By focusing on whole, nutrient-dense foods and systematically identifying individual triggers with professional guidance, you can develop a sustainable and supportive eating plan. Remember to consult a registered dietitian with experience in autoimmune diseases to create a strategy that safely addresses your specific needs and avoids nutritional deficiencies. A balanced diet, along with regular monitoring and medical oversight, is a powerful tool for managing the complexities of scleroderma.
