G&L Surgical Clinic

G&L Surgical Clinic is led by Dr Ganesh Ramalingam, a specialist general surgeon with over 20 years of experience in upper gastrointestinal, laparoscopic, and bariatric surgery. Operating from two locations — Mount Elizabeth Novena Hospital and HMI Medical Center at Farrer Park — the clinic covers the full spectrum of surgical and endoscopic digestive health care, including colonoscopy, gastroscopy, hernia repair, gallbladder surgery, acid reflux (GERD) surgery, and appendicectomy. Complementing its surgical services, G&L Surgical is an authorised provider of the AMILI BIO & ME Gut Microbiome Test, a Singapore-developed non-invasive stool test that analyses gut bacterial composition against Southeast Asian population benchmarks. The test identifies gut microbiome age, immunity and metabolic markers, digestive efficiency, and bacterial diversity, delivering a personalised report with dietary, lifestyle, and precision probiotic recommendations. Results are available within 4–6 weeks after sample receipt. An optional doctor consultation is available to contextualise findings within the patient's broader digestive and surgical health picture. This makes G&L Surgical one of the few surgical specialist clinics in Singapore offering a structured, evidence-based gut health assessment as a home test alongside its clinical procedures.
