Advanced Gastroenterology provides state-of-the-art diagnostic procedures and comprehensive treatment for health conditions affecting the upper and lower gastrointestinal tract. This full-service medical practice -- located in Union City, Tennessee -- includes three clinics: Summit Endoscopy Center, the MediSpa, and Summit Weight Loss.

Since Dr. Kofi Nuako opened Advanced Gastroenterology in 2004, they’ve proudly practiced an approach that values the unique symptoms and concerns of each patient, provides personalized care, and delivers the most advanced gastroenterology care.

At Advanced Gastroenterology patients receive medical care for gastrointestinal problems. From hemorrhoid treatment to determining the cause of persistent symptoms, such as abdominal pain, difficulty swallowing, indigestion, chronic diarrhea, or constipation, patients can depend on Dr. Nuako’s experience and an extensively-trained staff to help them overcome gastrointestinal challenges and return to optimal health.

Summit Endoscopy Center is a hub of expert diagnostic procedures where patients receive colonoscopies, upper GI endoscopies, sigmoidoscopies, and the innovative capsule endoscopy.

Many patients are candidates for capsule endoscopy, which involves swallowing a tiny camera tucked into a vitamin-sized capsule, then the camera transmits images as it travels through the length of the gastrointestinal tract.

For those who struggle to lose weight or to maintain a healthy weight, compassionate care is available at Summit Weight Loss. Whether you need to lose 10 pounds or 100 pounds, you receive dietary guidance, have access to the effective meal replacements, and benefit from the ongoing support and encouragement you need to lose weight successfully.
