9 Foods Making Your Heartburn Worse

The 9 most common heartburn triggers are fatty and fried foods, peppermint, citrus juices, chocolate, spicy foods, raw onions, alcohol, coffee, and carbonated drinks. These foods worsen heartburn mainly by relaxing the lower esophageal sphincter (LES), the muscle that keeps stomach acid from rising into the esophagus, or by increasing acid production.

Heartburn is the burning chest discomfort that defines gastroesophageal reflux disease (GERD), a condition affecting roughly 27.8% of U.S. adults. While triggers vary from person to person, identifying which foods set off your symptoms is one of the most effective ways to reduce flare-ups.

Below, we break down how each food affects your body and what you can do beyond diet to keep heartburn under control.

What Exactly Is Heartburn?

Heartburn stands out as the leading symptom of GERD, a digestive condition that impacts as many as 27.8% of adults in the United States.

GERD occurs when stomach contents push backward into the esophagus, producing symptoms such as:

• heartburn
• burping
• chest discomfort
• a sour or acidic taste caused by regurgitation

Under normal circumstances, stomach acid is prevented from reaching the esophagus thanks to a protective barrier called the lower esophageal sphincter (LES). This circular muscle typically remains shut and only opens during swallowing or burping. A weakened or overly relaxed LES is just one of several potential triggers for GERD.

Additional factors that may raise your chances of developing GERD include:

• slow stomach emptying, which can be linked to gastroparesis
• hiatal hernia
• carrying excess weight
• being older than 50
• heavy alcohol consumption
• smoking cigarettes
• pregnancy
• having a musculoskeletal condition
• using certain medications such as benzodiazepines, NSAIDs, or antidepressants

Managing GERD focuses on controlling its symptoms, heartburn included. Lifestyle adjustments are regarded as the foundation of GERD management, although many people also rely on additional treatments like medication. The American College of Gastroenterology (ACG) currently doesn’t advise individuals with GERD to cut specific foods entirely from their diets. That said, many healthcare providers still suggest that people managing GERD and heartburn steer clear of particular foods and drinks. Some patients also experience silent reflux (LPR), which can present without the classic burning sensation.

If heartburn is a regular struggle, identifying and avoiding certain trigger foods may help you take control of your symptoms. Here are 9 foods that might be causing your heartburn.

1. Fatty and Greasy Foods

Foods loaded with fat are known heartburn triggers, particularly greasy favorites like french fries and pizza. Scientists are still uncovering exactly how fat contributes to GERD symptoms, but fatty foods appear to intensify heartburn by prompting your body to produce substances that irritate the lining of your esophagus. Among these are bile salts, which exist in the stomach, and cholecystokinin (CCK), a hormone in your bloodstream that can loosen the LES and trigger acid reflux.

One study involving people with GERD discovered that over half of the 85 participants who identified food triggers pointed to high fat fried foods as a cause of their GERD symptoms, including heartburn. Additionally, once participants eliminated trigger foods for 2 weeks, the proportion who reported heartburn fell from 93% down to 44%. Keep in mind that researchers are still investigating which specific fats worsen GERD symptoms, though fried and oily foods appear to pack the biggest punch. For patients struggling with weight-related reflux, incisionless weight loss procedures may offer long-term relief.

2. Peppermint and Spearmint

Mint varieties like peppermint and spearmint are frequently believed to calm digestive discomfort. However, evidence indicates these mints may actually provoke heartburn. Research shows that peppermint lowers LES pressure, which can set off heartburn episodes.

While mint has the potential to trigger GERD symptoms, it tends to affect only a small percentage of those with GERD. If you notice heartburn flaring up after consuming mint-containing products, consider removing them from your diet to check if your symptoms improve.

3. Citrus-Based Drinks

Sipping on citrus juices may set off heartburn symptoms. Orange and grapefruit juices are frequently cited as culprits behind GERD symptoms like heartburn. Still, the exact mechanism behind how citrus juices spark heartburn remains unclear. Even so, many individuals living with GERD steer clear of them to minimize heartburn flare-ups.

4. Chocolate Treats

Chocolate is yet another notorious heartburn trigger. Components found in chocolate, including cacao and caffeine, can loosen the LES and boost the esophagus’s contact with acid. Plenty of people notice heartburn symptoms after indulging in chocolate, and research has demonstrated that chocolate can lower LES pressure. Even so, it’s uncertain whether cutting chocolate out completely leads to better heartburn outcomes for everyone. If you discover that chocolate brings on or intensifies your heartburn, consider removing it from your meals. For persistent cases, the LINX Reflux Management System provides a modern surgical solution.

5. Hot and Spicy Dishes

Spicy dishes have a well-known reputation for setting off heartburn. Yet, the exact way they trigger heartburn isn’t entirely clear. However, one study of individuals with GERD discovered that chili capsules boosted gastric accommodation, the process where the upper stomach expands in response to a meal. Studies have found that individuals with GERD typically exhibit a heightened gastric accommodation reflex. This correlates with greater relaxation of the LES, potentially leading to heartburn.

The same study also revealed that chili capsules led to stronger burning sensations in the stomach and more intense heartburn among GERD sufferers, compared to those given a placebo. Another study involving 4,633 Iranian adults revealed that consuming large amounts of spicy foods was linked with a higher risk of heartburn in men, although the same association wasn’t found in women. Additionally, spicy ingredients can aggravate an already inflamed esophagus, potentially making heartburn symptoms worse. If you suspect that spicy foods are behind your heartburn, try cutting them from your diet. In rare cases, chronic symptoms may signal conditions like achalasia that require specialist evaluation.

6. Raw Onions

Onions, particularly when raw, rank as a frequent heartburn trigger. Similar to other items on this list, onions provoke heartburn symptoms in many GERD sufferers. However, the exact reason onions trigger or worsen heartburn remains unclear.

In a study dating back to the 1990s, individuals experiencing heartburn ate a regular hamburger one day, and the next day they consumed an identical hamburger topped with onions. The onion-topped burger made heartburn symptoms notably worse compared to the plain version. Still, additional research is required to establish whether every person with heartburn should think about cutting out or limiting their onion consumption.

Additionally, onions pack plenty of FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols), a group of small indigestible carbohydrates known to cause digestive upset in certain individuals. For those sensitive to FODMAPs, these compounds can trigger heartburn.

7. Alcoholic Drinks

Drinking alcohol in moderate to heavy amounts can intensify GERD symptoms, heartburn included. This happens because alcohol loosens the LES, potentially letting stomach acid slip up into the esophagus and spark heartburn. Additionally, studies reveal that alcohol consumption ranks as a risk factor for GERD. A review covering 29 studies discovered that people drinking alcohol more than 5 times or days per week were over twice as likely to develop GERD compared to those who rarely or never drank. Exploring surgical options like fundoplication may be worthwhile for severe, treatment-resistant reflux.

8. Coffee and Other Caffeinated Drinks

Certain individuals may notice heartburn after drinking coffee or other caffeinated drinks. The reason is that caffeine has been found to loosen the lower esophageal sphincter, which may heighten the chances of acid reflux and heartburn. Additionally, coffee may ramp up gastric acid production, potentially making heartburn worse.

While coffee can trigger heartburn for some, not every study has confirmed a connection between coffee and acid reflux symptoms. A study involving 1,837 participants, where 25% had GERD, failed to identify a meaningful link between coffee drinking and GERD symptoms. Although the evidence is mixed, if coffee doesn’t cause you any trouble, there’s no reason to give it up. Conversely, if coffee triggers reflux and heartburn for you, cutting back or avoiding it altogether is the best approach. The TIF procedure with EsophyX is another incisionless option patients may consider.

9. Soft Drinks and Fizzy Beverages

A lot of people report getting heartburn after gulping down sodas and fizzy drinks. Research indicates these beverages can loosen the esophageal sphincter and intensify stomach acid acidity, both of which are risk factors for heartburn. In reality, soft drink consumption is viewed as a significant driver of nighttime heartburn, commonly referred to as nocturnal heartburn.

Some research has linked consuming soft drinks to intensified symptoms in GERD sufferers. For instance, an older study revealed that people drinking carbonated beverages faced a 69% higher likelihood of experiencing reflux symptoms such as heartburn. If soda or other fizzy drinks bring on heartburn for you, cutting back or eliminating carbonated beverages entirely is the way to go. Patients dealing with related conditions may benefit from abdominal hernia and heartburn treatment tailored to their diagnosis.

More Strategies to Keep Heartburn Under Control

Beyond cutting trigger foods from your plate, several other strategies can help you keep heartburn in check:

• Maintain a healthy body weight. Obesity has been tied to GERD. Shedding pounds and keeping a healthy weight may ease GERD symptoms, heartburn included.
• Consider a lower carb diet. Research suggests that adopting a lower carb eating plan may help ease GERD symptoms. Cutting back on refined carbs and added sugars alone may also provide relief.
• Skip lying down after eating. Healthcare providers commonly suggest that GERD sufferers finish eating at least 3 hours before hitting the sack. Reclining shortly after meals can make GERD symptoms such as heartburn worse.
• Adopt a Mediterranean-style diet. The Mediterranean diet, loaded with fiber-rich choices like legumes and vegetables along with healthy fats from olive oil and fish, may assist in controlling GERD symptoms.
• Stay physically active. One review noted that engaging in 30 minutes of exercise 3 times weekly was tied to a lower risk of GERD.
• Raise your head while sleeping. Propping up your upper body in bed may ease GERD symptoms and enhance your sleep quality.

Plenty of additional strategies exist for improving and controlling GERD symptoms. If heartburn is a persistent issue, working with a healthcare provider to build a tailored treatment plan is the smartest move. Many patients in Florida seek out the best hiatal hernia doctors in Tampa, FL for advanced, specialized care.
