Gastroesophageal Reflux Disease (GERD) is a chronic digestive disorder that affects the lower esophageal sphincter (LES), the muscle connecting the stomach and the esophagus. GERD occurs when the LES weakens, allowing stomach acid and other contents to flow back into the esophagus (reflux). Symptoms of GERD include heartburn, chest pain, regurgitation, and difficulty swallowing. Common causes of GERD include obesity, smoking, certain foods, and certain medications. Diagnosis of GERD is typically based upon symptoms and an examination of the esophagus. Treatment of GERD can include lifestyle changes, medications, or in more extreme cases, surgery.

Gastric cancer, also known as stomach cancer, is a type of cancer that develops in the lining of the stomach. Symptoms of gastric cancer can include persistent indigestion, abdominal pain, heartburn, nausea, vomiting, difficulty swallowing, and weight loss. Diagnosis is usually made through a combination of imaging tests, such as X-rays and CT scans, and biopsies, which involve taking a small sample of tissue from the stomach for examination. Treatment for gastric cancer typically involves surgery, chemotherapy, and radiation therapy. Surgery involves removing the tumor, while chemotherapy and radiation are used to destroy any remaining cancer cells.

Esophageal cancer is a type of cancer that affects the lining of the esophagus. Symptoms may include difficulty swallowing, weight loss, chest pain, and coughing up blood. Diagnosis is typically made by performing an endoscopy and biopsy. Treatment may include surgery, radiation therapy, and chemotherapy. Early diagnosis and treatment can improve the prognosis for those affected by esophageal cancer.

The Gastric system is responsible for the digestion and absorption of food and nutrients in the body. Several disorders can affect this system, ranging from mild to severe. Common top disorders of the Gastric system include Gastroesophageal Reflux Disease (GERD), Irritable Bowel Syndrome (IBS), Inflammatory Bowel Disease (IBD), Peptic Ulcer Disease (PUD), and Gastroparesis. GERD is a condition resulting from the reflux of stomach acid into the esophagus, resulting in heartburn, chest pain, and difficulty swallowing. IBS is a disorder that causes abdominal pain and changes in bowel habits. IBD is an inflammatory disorder that affects the lining of the digestive tract, causing abdominal pain, diarrhea, bleeding, and weight loss. PUD is an ulcer in the lining of the stomach or small intestine that causes abdominal pain and sometimes bleeding. Gastroparesis is a condition where the stomach muscles are weakened, leading to food sitting in the stomach for too long and not being digested properly. Treatment for these disorders include lifestyle modifications, medications, and in some cases, surgery.
