Does Coffee Cause Acid Reflux? (Answered)

Caffeine is found in many beverages, it has been identified as a cause of heartburn in some people and it can also trigger GERD because caffeine can relax the LES.

Caffeinated foods and beverages have the potential to increase the acidity of gastric secretion. Caffeine can decrease the pressure of the Lower Esophageal Sphincter (LES) which will cause its malfunction. Damaged LES is the main cause of GERD and caffeine can lower the LES which can trigger GERD.

LES opens to allow the foods and liquids to pass in the stomach and then closes to block the esophagus and stomach acid. If LES is damaged or becomes weak, it will not close properly; thereby allowing the stomach acids to wash back to the esophagus, which will cause injury to its lining resulting in heartburns, a sore throat, and/or chest pain.

How can I drink coffee and avoid acid reflux?

To avoid getting acid reflux when you’re having your coffee, try adding a pinch of salt into your drink. It has been said that salt reduces the chances of getting acid reflux from coffee. You can also opt for a darker roast of coffee beans if you don’t want to add salt.

Coffee contains organic acid which gives the tangy taste that most coffee consumers love. Although it gives a nice taste, it can cause acid reflux, not to all people, but to some who are sensitive to high caffeine.

All ages drink coffee now and have developed a dependency to the point that when their daily caffeine quantity is unmet, the body starts to act up which can lead to headaches or migraines.

Coffee, coffee grounds, and coffee beans

If you want to keep drinking coffee and at the same time want to avoid acid reflux, here are some things you can do.

  • Dark roasted beans – Dark roasted beans are less acidic because these beans are roasted for a longer time which lessens the acidity levels.
  • Low elevation coffee – Coffee cherries that are grown at low elevations tend to have less acid. Consuming such coffees can help in preventing acid reflux.
  • Cold brew – For cold brew, cold water is used to extract flavors from the beans which neutralize the acid. So switch to cold brew at least for some time, so that your Lower Esophageal Sphincter can gain back its pressure.
  • A pinch of salt – Salt is mostly used to decrease the bitterness in the coffee, but it can neutralize the acidic level which will cause less acid reflux.

To conclude

Coffee carries a huge amount of caffeine and caffeine in many cases has been considered to have negative effects on the human body. One of them is that it can cause acid reflux, caffeine reduces the pressure of LES which is supposed to block the acids from entering into the stomach. As caffeine decreases the pressure of LES, it gets weaker and can’t close completely, which leads to acid reflux.

Many people are sensitive to high caffeine; thus it causes them to have acid reflux. If you are experiencing this, you should reduce your intake of caffeine.

If you are getting acid reflux more than usual and it is becoming uncomfortable, you can consume coconut water, low-fat cold milk, smoothies, probiotics, lemon with ginger juice, and/or apple cider vinegar with warm water.

Instant and many other coffees which are not roasted for a long period of time have much more acidity than the ones which are roasted for a long time. The acidity also depends on the coffee brand and type, espresso and cold brew are much less acidic.

Coffee is a huge part of our lives and honestly, we need it to perform better. I understand, if you want to keep drinking coffee and don’t want acid reflux, you can drink dark roasted coffee, low elevation grown coffee, cold brew, or just add a pinch of salt.
