Dr. Saad F. Habba, MD

Dr. Saad F. Habba is a gastroenterologist with more than 40 years of experience and an attending consultant physician at Overlook Medical Center. He maintains a private practice in Summit, serves as president of the Gastro‑Surgi Center of New Jersey, and is a former chief of gastroenterological endoscopy at UMDNJ. An author, speaker, and honored clinician (including international distinctions such as knighthood and recognition by the Queen of England), Dr. Habba combines deep clinical experience with academic contributions — including a textbook chapter in Conn’s Current Therapy and 26 peer-reviewed publications. His long-standing focus on digestive health, patient-centered care, and innovative research makes him a recognized gastroenterology expert internationally. 

Known for “putting a name to a mystery diagnosis,” Dr. Habba first described Habba Syndrome — a condition that links chronic diarrhea to gallbladder dysfunction and inappropriate bile — in 2000, and he has …advocated that “IBS” often represents a collection of different conditions rather than a single diagnosis (published in Medical Hypotheses, 2011, and again in the Scandinavian Journal of Gastroenterology, 2012). He emphasizes thorough investigation to identify the definitive cause of symptoms so he can treat the root problem, not just the symptom, often using targeted radiological testing and bile acid‑binding therapy to restore quality of life. Patients choose Dr. Habba for his diagnostic clarity, decades of endoscopic expertise, and a practical, empathetic approach to complex gastrointestinal disorders.

Symptoms of Habba Syndrome include: 

• Chronic diarrhea – three or more bowel movements (solid, watery, or explosive) a day for three or more months
• Post-prandial (after meals) diarrhea
• Fear of eating (to avoid symptoms)
• Dysfunctional gallbladder, determined by radiological testing
• Failure to respond to IBS therapy
• Favorable response to bile acid-binding agents
• Bathroom Mapping
