Doctors Near You for Acid Reflux in Redwood city

Acid reflux is a condition where stomach acid flows backward into the esophagus, causing irritation and discomfort. This backward flow, known as gastroesophageal reflux (GER), results in symptoms such as a burning sensation in the chest (heartburn), regurgitation of acidic or bitter-tasting fluid, and difficulty swallowing. Acid reflux can also lead to a chronic cough, sore throat, and hoarseness. The primary cause of acid reflux is the malfunction of the lower esophageal sphincter (LES), a ring of muscle at the base of the esophagus that normally prevents stomach acid from entering the esophagus. When the LES weakens or relaxes inappropriately, it allows acid to escape into the esophagus. Contributing factors include obesity, pregnancy, certain foods and beverages (such as spicy foods, citrus fruits, caffeine, and alcohol), smoking, and large meals. Other causes can be a hiatal hernia, where part of the stomach pushes through the diaphragm, or increased stomach pressure due to chronic coughing or heavy lifting. Treatment for acid reflux often begins with lifestyle and dietary modifications. Patients are advised to avoid trigger foods and beverages, eat smaller meals, and not lie down immediately after eating. Weight loss and smoking cessation can also be beneficial. Over-the-counter antacids and medications such as H2 receptor antagonists (e.g., ranitidine) and proton pump inhibitors (PPIs, e.g., omeprazole) help reduce stomach acid production and alleviate symptoms. For severe or persistent cases that do not respond to medication, surgical options such as fundoplication, where the top of the stomach is wrapped around the LES to strengthen it, may be considered. Consulting a healthcare provider is essential to manage symptoms effectively and prevent complications such as esophageal damage or Barrett's esophagus, a condition that can increase the risk of esophageal cancer.
