                      Your digestive system impacts your overall health and well-being, and when symptoms like changes in bowel habits, abdominal pain or constant heartburn are persistent, they can have a big impact on quality of life.

                      Specially trained in digestive disorders and identifying the wide range of symptoms that accompany them, the experienced providers at Northwest Gastroenterology diagnose and treat issues affecting the esophagus, stomach, intestine, colon, pancreas, gallbladder, liver and other organs

                      With a focus on the entire digestive system, our providers work with you to understand your concerns and symptoms and develop a personalized plan for testing and treatment.

                      Common GI symptoms can include:

                      • Change in bowel habits such as constipation or diarrhea
                      • Consistent heartburn
                      • Abdominal pain or discomfort
                      • Difficulty swallowing
                      • Hemorrhoids
                      • Blood in stool
                      • Abdominal bloating and gas
                      • Unexplained weight loss

                      Conditions treated Include:

                      • Gallstones
                      • Ulcers
                      • Heartburn and GERD (gastroesophageal reflux disease)
                      • Inflammatory bowel disease, including Crohn’s disease and ulcerative colitis
                      • Irritable bowel syndrome
                      • Acute and chronic pancreatitis
                      • Dietary sensitivities such as celiac disease and lactose intolerance
                      • Diverticular disease
                      • Gastrointestinal viruses, infections and general discomfort
                      • Stomach, esophageal and colorectal cancer
                      • Swallowing disorders

                      Colon Cancer Screenings
                      Colon cancer is the third most common cancer in the country and the second leading cause of cancer death. However, it is also one of the easiest cancers to prevent with a healthy lifestyle, preventive screenings and early detection. Our gastroenterology providers conduct both screening and diagnostic colonoscopies - an exam of the lower digestive system that helps detect cancer in its earliest stages.
