Upper GI Disorders
The upper gastrointestinal (GI) tract is a highly coordinated pathway designed to safely receive, break down, and begin absorbing the nutrients from the food and drink you consume. When an issue disrupts this process, it can lead to chronic discomfort and impact your daily quality of life.
How Your Upper GI Tract Works
The upper digestive system relies on a sequence of vital organs and muscular valves working seamlessly together:
The Esophagus: After you swallow, food and liquids enter the throat and travel down the esophagus, a muscular tube leading directly to the stomach.
The Lower Esophageal Sphincter (LES): At the base of the esophagus sits a specialized ring of muscle known as the LES. This acts as a one-way safety valve, opening briefly to let food pass into the stomach and then closing tightly to prevent highly acidic gastric juices from splashing back upward.
The Stomach: Inside the stomach, powerful gastric acids and digestive enzymes churn and break down solid food into a digestible liquid form.
The Duodenum: This is the first section of your small intestine. As the liquid food enters the duodenum, it is met by bile and pancreatic enzymes that break it down even further, allowing your small intestine to successfully absorb the vast majority of vital nutrients into your bloodstream.
Common Upper GI Disorders
An interruption in tissue integrity, nerve signaling, or muscle function can occur anywhere along this pathway. Our board-certified gastroenterologists specialize in diagnosing and treating a comprehensive range of upper GI issues, including:
Reflux & Esophageal Conditions: Gastroesophageal Reflux Disease (GERD), chronic acid reflux, heartburn, Barrett’s esophagus, hiatal hernias, and chronic sore throats.
Functional & Swallowing Disorders: Difficulty or pain when swallowing (dysphagia), a sensation of food getting stuck in the throat or chest, chronic nausea, vomiting, gas, and bloating.
Inflammatory & Structural Lesions: Gastritis (inflammation of the stomach lining), gastric or peptic ulcers, internal gastrointestinal bleeding, unexplained abdominal pain, and upper GI cancers.
When to Seek Specialized Care: If you are experiencing upper digestive symptoms that are chronic, worsening, or severe, it is vital to see a gastrointestinal physician. Early detection is paramount; identifying a GI issue in its initial stages significantly broadens your treatment options and dramatically increases the likelihood of a swift, successful recovery.
Proactive Diagnosis and Targeted Care
If your physician suspects an underlying condition in your upper digestive tract, they will utilize advanced, minimally invasive diagnostic tools to find clear answers.
The most effective method is an upper endoscopy (also known as an EGD). During this quick, outpatient procedure, a gastroenterologist guides a slim, flexible tube equipped with a high-definition camera and a light down the esophagus and into the stomach and duodenum. This allows our clinical team to directly inspect the delicate interior lining, instantly identify inflammation, ulcers, or structural changes, and even take tiny, painless tissue samples (biopsies) for immediate lab analysis.
