Fasting has been a long-standing practice across various cultures and religious traditions for centuries. For example, it is observed during Yom Kippur in Judaism and Ramadan in Islam. In addition, intermittent fasting has gained significant popularity as a weight loss method in recent years. While fasting is often associated with numerous health benefits, it’s important to carefully consider how this practice may affect your stomach, particularly with regard to the potential development of ulcers.

Stomach ulcers, also known as peptic ulcers, are painful sores that develop in the lining of your stomach or the upper part of your small intestine. These ulcers can be caused by several factors, but the most common is a bacterial infection with Helicobacter pylori, which weakens the stomach lining and makes it more susceptible to damage from stomach acid. Other factors such as the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and stress can also contribute to their development. Though irregular eating patterns aren’t directly responsible for ulcers, they can certainly create an environment that encourages their development. So many wonder, can fasting cause stomach ulcers? 

Can Fasting Cause Ulcers?

Peptic ulcers are commonly caused by bacterial infections, particularly Helicobacter pylori, which damage the protective lining of the stomach and make it vulnerable to the acid produced during digestion. While fasting itself doesn’t directly cause ulcers, irregular eating habits—such as extended periods without food—can trigger excess acid production, which may irritate the stomach lining and contribute to ulcer formation.

A study conducted by the World Health Organization in the United Arab Emirates during Ramadan found that while fasting did not directly cause an increase in ulcer cases, the frequency of ulcers was slightly higher after the fasting period. The study indicated that lifestyle factors, such as smoking, and pre-existing conditions were more closely associated with ulcer development than the fasting itself. These findings suggest that while fasting may not directly cause ulcers, it can affect individuals who already have certain risk factors or who engage in unhealthy behaviors during the fasting period.

Maintaining a balanced eating routine is essential for stomach health. Regular meals help promote mucus production that safeguards the stomach lining and regulates acid levels. This emphasizes the importance of a consistent eating pattern, especially when incorporating fasting or altering your eating schedule. Skipping meals for long stretches, as seen in fasting, can lead to acid buildup, which can harm the protective stomach lining and potentially lead to ulcers over time.

Additionally, it's crucial to consider what you consume after breaking your fast. Certain foods, such as acidic items, spicy meals, or alcohol, can aggravate the stomach lining and contribute to discomfort or ulcer formation. Instead, start with low-fat meals, lean meats, and mild fruits to ease your stomach back into digestion and protect your vulnerable lining. By making mindful food choices during and after a fast, you can minimize the risk of irritation and support overall stomach health.

Conclusion

While fasting can contribute to conditions that might increase the risk of developing stomach ulcers, it is not the sole cause. People who engage in fasting for health or religious reasons should be cautious and aware of how their body responds, especially when it comes to stomach acid production. If you experience discomfort or symptoms of ulcers, such as pain or bloating, it’s essential to seek advice from a healthcare professional.
