Physiological abnormalities seem to be the main cause for acid reflux (weakness of the lower esophageal sphincter, uncontrolled contractions of the sphincter, low pressure at the bottom of the esophagus due to abnormal positioning of the sphincter, etc). People who suffer from GERD as a consequence of physiological abnormalities can only overcome their condition through the means of ongoing medical treatment or surgery.
The best way of controlling the condition is through the means of good diet. Appropriate diet has a great importance in preventing and controlling GERD. Due to the fact that excessive production of stomach digestive fluids also contributes to the condition, an appropriate diet can ameliorate the symptoms of acid reflux. A good diet should exclude: foods that are rich in fat, milk, caffeine-based products, spicy foods, fried foods, alcoholic beverages and smoking.
