Caffeine and alcohol are two of the most widely consumed substances in the world, often enjoyed for their stimulating and relaxing effects, respectively. However, their impact on our health is a topic of much debate, particularly regarding acid reflux. Acid reflux, or gastroesophageal reflux disease (GERD), is a condition where stomach acid flows back into the food pipe, causing symptoms such as heartburn, indigestion, and an upset stomach. While the causes of acid reflux are multifaceted and vary from person to person, this article will delve into the specific roles of caffeine and alcohol in exacerbating this condition and explore which of the two substances may be more detrimental.
Is Caffeine or Alcohol Worse for Acid Reflux?
| Characteristics | Caffeine | Alcohol |
|---|---|---|
| Effect on acid reflux | Caffeine may relax the lower esophageal sphincter, triggering acid reflux or making it worse. | Alcohol may not directly cause acid reflux, but it could aggravate symptoms. |
| Scientific evidence | There is little scientific evidence to support the claim that caffeine aggravates acid reflux. | Research has shown that alcohol consumption can inflame and irritate the stomach and impair the functioning of the esophageal sphincter. |
| Recommendations | Doctors often recommend that individuals with acid reflux avoid caffeine. | Doctors recommend that individuals with acid reflux limit alcohol consumption to one drink at a time and avoid drinking right before going to bed. |
| Trigger foods | Coffee, tea, dark chocolate, certain protein bars, and energy drinks contain caffeine and can trigger acid reflux. | All forms of alcohol, including beer, wine, and spirits, are thought to have negative effects on people with acid reflux. |
| Alternatives | Decaf coffee and tea are alternatives for individuals with acid reflux who wish to reduce caffeine intake. | Non-alcoholic beverages are alternatives to alcohol for individuals with acid reflux. |

What You'll Learn
Caffeine relaxes the lower esophageal sphincter
While the link between caffeine and acid reflux is not yet fully understood, some studies suggest that caffeine relaxes the lower esophageal sphincter, triggering acid reflux or making it worse. This is supported by anecdotal evidence from individuals suffering from gastroesophageal reflux disease (GERD) who report that caffeine may trigger or intensify acid reflux episodes.
Caffeine is a known component of many foods and beverages, including coffee, tea, soda, energy drinks, chocolate, and certain protein bars. When consumed, caffeine can cause the lower esophageal sphincter to relax, allowing stomach contents to flow back up into the esophagus. This can result in discomfort and symptoms such as heartburn, an upset stomach, or a bitter taste in the mouth.
The impact of caffeine on acid reflux may vary from person to person. While some individuals find that caffeine aggravates their reflux symptoms, others may not experience any issues. It is important for people with acid reflux to identify their specific triggers through methods such as keeping a food diary. This can help them make informed decisions about their diet and lifestyle choices.
For those who find that caffeine triggers their acid reflux, reducing or eliminating caffeinated products from the diet may be beneficial. Decaffeinated versions of coffee and tea are available, and individuals can also explore alternative beverages like water, which has been associated with a reduced risk of GERD symptoms. Additionally, paying attention to the type of coffee and its preparation can help, as different roasts and brewing methods yield varying levels of acid and caffeine content.
While the relationship between caffeine and acid reflux is not yet fully understood, the available evidence suggests that caffeine may indeed relax the lower esophageal sphincter, contributing to acid reflux symptoms. Further research is needed to establish a clearer understanding of this relationship and its implications for individuals with acid reflux or GERD.

Alcohol damages the esophageal and gastric lining
While both caffeine and alcohol can trigger acid reflux, alcohol is worse for acid reflux as it damages the oesophageal and gastric lining. Alcohol abuse can lead to a range of oesophageal issues, each with its own set of complications.
Firstly, alcohol abuse can cause direct mucosal damage to the oesophageal and gastric lining. This is because, after ingestion, alcohol comes into contact with the oral cavity, pharynx, and oesophagus in a mostly undiluted form. Large amounts of alcohol can, therefore, lead to injuries to the mucosal lining of these areas.
Secondly, alcohol can cause Barrett's oesophagus, which is a condition characterised by damage to the lining of the oesophagus. This condition can lead to the development of abnormal cells, increasing the risk of cancer.
Thirdly, alcohol abuse can cause oesophageal stricture, which is when the oesophageal lining is damaged, causing the oesophagus to narrow and making swallowing difficult.
Fourthly, alcohol can contribute to the development of oesophagitis, an inflammation of the oesophagus.
Finally, a single episode of heavy drinking can weaken the function of the oesophageal sphincter, which may lead to acid reflux and heartburn. The oesophageal sphincter is the muscle that prevents stomach contents from flowing back into the oesophagus.

Coffee and tea consumption
Some studies indicate that there is seemingly no relationship between caffeine and acid reflux. However, anecdotal evidence suggests that caffeine may trigger or intensify acid reflux episodes. As with other foods, caffeine may affect different people in different ways. It is important to assess how you feel after consuming caffeinated drinks and to pay attention to how different types affect you before eliminating them from your diet.
Tea, specifically, has also been linked to acid reflux. A study found a stronger association between decaffeinated tea and the risk of acid reflux symptoms. This may be due to changes in the pH of the refluxate. Drinking water instead of tea or coffee can help reduce the risk of acid reflux symptoms.

Carbonated beverages
The intake of carbonated beverages has been linked to the lowest intraesophageal pH, which can further worsen acid reflux symptoms. Carbonated drinks are also a strong risk factor for dental erosion, as they are often sugary. The sugar combines with the carbonation to create an optimal environment for tooth decay.
Some studies have shown that drinking water instead of carbonated beverages reduces the risk of GERD symptoms. It is important to assess how you feel after consuming carbonated drinks and to pay attention to how different types affect you before eliminating them from your diet completely.
Fast food is often served with carbonated drinks, which may further contribute to acid reflux. It is recommended to opt for menu items that are less likely to contribute to acid reflux when eating fast food.

Alcohol's impact on the body
While the impact of caffeine on acid reflux is not entirely clear, with conflicting studies and anecdotal evidence, alcohol's impact on the body and its link to acid reflux is more apparent. Alcohol can cause direct damage to the oesophageal and gastric lining, and it relaxes the valve between the oesophagus and the stomach. This relaxation of the lower oesophageal sphincter can allow stomach contents to reflux into the oesophagus, causing discomfort and acid reflux symptoms. Additionally, alcohol may encourage the stomach to produce more acid.
The impact of alcohol on acid reflux is further influenced by its interaction with other factors. Excess weight or obesity can increase pressure on the abdomen, contributing to reflux. Alcohol consumption can also impair the functioning of the oesophageal sphincter, and certain drinks associated with heartburn, such as caffeinated or carbonated beverages, may aggravate symptoms when combined with alcohol.
While alcohol may not directly cause gastroesophageal reflux disease (GERD), it can worsen existing symptoms. This is supported by a study that adjusted for multiple factors, including alcohol intake, and found an association between beverage intake and the incidence of GERD symptoms. However, the relationship between alcohol and GERD is not fully understood, and more mechanistic research is needed to clarify how alcohol modulates GERD symptoms.
To manage acid reflux, individuals with GERD are often advised to limit alcohol consumption. This may include having no more than one drink at a time and avoiding drinking close to bedtime to reduce the likelihood of night-time acid reflux. Additionally, replacing alcoholic beverages with non-irritating alternatives, such as water, can help reduce the risk of GERD symptoms.
In summary, alcohol can negatively impact the body's digestive system, particularly for those with GERD, by damaging the oesophageal lining, relaxing the lower oesophageal sphincter, and increasing acid production in the stomach. These factors contribute to the aggravation of acid reflux symptoms. While the relationship between alcohol and GERD requires further investigation, managing alcohol consumption is an essential lifestyle change to alleviate acid reflux.
