About Dr. Kittithat Tantitanawat
Dr. Kittithat Tantitanawat is a board-certified gastroenterologist at YOUNIFY Clinic, a physician-led Healthy Aging and Wellness Center on Silom Road in central Bangkok. He practises digestive medicine with a focus on prevention, early detection and minimally invasive endoscopy: diagnosing and treating through the endoscope rather than through surgery wherever that is a sound option for the patient.
He earned his Doctor of Medicine from the Faculty of Medicine, Chulalongkorn University, completed his Internal Medicine residency at Srinagarind Hospital, Khon Kaen University, and went on to both a Gastroenterology Fellowship and an Advanced Endoscopy Fellowship at King Chulalongkorn Memorial Hospital. He holds the Thai Board of Internal Medicine and the Thai Subspecialty Board of Gastroenterology, together with a Clinical Fellowship in Advanced Gastrointestinal Interventional Endoscopy.
MAIN AREAS OF PRACTICE
-
Gastrointestinal cancer screening: personalised screening and early detection, with endoscopic treatment of early lesions where that is appropriate. The purpose of screening is to find changes before they cause symptoms, when the options available are simpler.
-
Therapeutic and diagnostic endoscopy: minimally invasive procedures carried out through the endoscope, with attention to patient comfort as well as accuracy.
-
Weight and metabolic care: endoscopic, non-surgical bariatric procedures alongside medical and lifestyle management of metabolic disease. With endoscopic sleeve gastroplasty, weight loss is generally around 15 to 20 per cent of body weight over the first year; results depend on the individual.
-
Chronic digestive conditions: assessment and long-term management of GERD (acid reflux), gastritis, irritable bowel syndrome and chronic constipation — the everyday problems that quietly shape how well a person lives.
Care is planned around the individual rather than around a standard package. A consultation starts with the history, the examination and any previous investigations; testing is chosen to answer a specific question, and treatment follows from what is actually found. Findings, options and their limits are explained plainly before any decision is made. Results differ from person to person.
Consultations are available in Thai and English, and the clinic regularly cares for international patients travelling to Bangkok, supported by YOUNIFY Clinic's medical travel pathway from pre-arrival planning through to departure and follow-up.
