A Modified Barium Swallow Study is a widely used video fluoroscopic evaluation of the functional anatomy and physiology of swallowing that permits visualization of food or liquid flow from your mouth to your esophagus. The information gained from the examination is critical for identifying the type and severity of swallowing impairment, determining the safety of oral intake, and formulating oral intake recommendations and treatment planning. The test will help you, your doctor, and the SLPs plan what type of foods and liquids are easiest for you to swallow. The SLPs will also identify positions and ways to help you swallow more easily and safely.
