Eating foods that are high in fiber or that are spicy or oily, suffering from stress and eating at irregular times are causes for elevated levels of stomach acid, as stated by HealthGuidance.org. The stomach's inner layers produce gastrin, a hormone boosting creation of hydrochloric acid to digest food.
Acidity in the stomach is beneficial as it helps reduce the growth of bacteria, which would otherwise grow in decomposing food. Acid also facilitates the breakdown of complex molecules in the food, assisting the digestion of nutrients. However, when acid levels become too high, a person feels a burning sensation as the acid acts on the stomach's inner layers, according to HealthGuidance.org
Most of the cases involving excess stomach acid stem from eating habits. Because different people respond differently to foods, people who suffer from too much acid should make a journal indicating the foods that cause the discomfort. Noting the time and amount of consumption helps people identify the causal links between specific foods and acidity. Avoiding the foods that cause acid most frequently is the best way to gain relief from this condition. Eating smaller amounts at regular times throughout the day, rather than eating one or two large meals at odd times, is another way to keep acid levels consistent and manageable, notes HealthGuidance.org.
