The diagnostic tool can pinpoint common causes and cure for chronic reflux and heartburn based on your lifestyle, symptoms and physical condition. In most cases, acid reflux and GERD are merely a symptom of underlying digestive problems caused by one or more factors such as: bacterial or fungal infection, neurological impairment, obesity, stress, diet, allergic reactions, posture, enzyme insufficiency and hypochloridia. Pinpointing the precise cause(s) is a key component of recovery. Conventional acid suppression drugs like proton pump inhibitors and antacids simply mask symptoms, neglecting the underlying causes of reflux. The Reflux Defense System is a systematic approach that ascertains the body's areas of weakness and targets the causes directly with natural remedies, dietary supplements, exercises and diet.
