Does Sugar Cause Heartburn?

Excess sugar

Consuming excessive amounts of sugar, particularly in the form of certain sugary foods and beverages, can contribute to the development of heartburn in some individuals. Heartburn occurs when stomach acid flows back into the esophagus, causing a burning sensation in the chest or throat. While sugar itself may not directly cause heartburn, certain factors related to sugar consumption can play a role:

  • Relaxation of the Lower Esophageal Sphincter (LES): The LES is a muscle at the bottom of the esophagus that acts as a valve, preventing stomach acid from flowing back into the esophagus. High-sugar diets may contribute to the relaxation of the LES, increasing the risk of acid reflux and heartburn.
  • Obesity and Weight Gain: Excessive sugar intake, especially in the form of sugary snacks and beverages, can contribute to weight gain and obesity. Being overweight is a risk factor for heartburn as it can put pressure on the stomach and increase the likelihood of acid reflux.
  • Dietary Choices: Foods high in sugar may be part of an overall diet that includes other triggers for heartburn, such as fatty or spicy foods. Combining these factors can contribute to acid reflux.
  • Bacterial Overgrowth: Diets high in sugar may contribute to an imbalance in gut bacteria, potentially leading to conditions like small intestinal bacterial overgrowth (SIBO). SIBO has been associated with an increased risk of acid reflux.

It’s important to note that individual responses to dietary factors can vary. While reducing sugar intake may help some people manage heartburn, others may find relief by avoiding other triggers, such as acidic or spicy foods. If you experience frequent or severe heartburn, it’s advisable to consult with a healthcare professional for a proper evaluation and personalized recommendations. Lifestyle modifications, dietary changes, and, in some cases, medications may be recommended based on the underlying causes of the heartburn.
