Dr. McCallum is Professor and Founding Chairman of the Department of Internal Medicine, Paul L. Foster School of Medicine, Texas Tech University Health Sciences Center at El Paso, TX.
He also serves as Chief of the Research Division of Gastroenterology, Hepatology and Nutrition and as the Medical Director of the Diagnostic Center for GI Motility and Functional Bowel Disorders.
Dr. McCallum’s research has focused on the physiology, pathophysiology, and pharmacology of gastrointestinal smooth muscle and the role of nerves and electrical activity relating to functional GI and motility disorders. His past research has resulted in several innovative approaches to diagnosing and treating these conditions.
With support of the IFFGD grant, Dr. McCallum’s research will be aimed at defining the role of nerves and electrical activity in stomach motility and in the generation of symptoms in gastroparesis. Using non-invasive electrical stimulators the research will explore the use of acupuncture points to reduce nausea and vomiting.
The ultimate goal is to provide a new and practical therapy option for the treatment of the symptoms and of their complications.
