Ms Hua Zen Ling

Dr Hua Zen Ling, known to many patients as Dr Zen, is a Consultant Obstetrician and sub-specialist in Fetal and Maternal Medicine. She is based at Chelsea and Westminster Hospital and joined London Pregnancy Clinic in January 2026, where she works predominantly at LPC West.

Dr Ling is widely respected for her calm, thoughtful, and highly personalised approach to pregnancy and ultrasound care. She supports women who value reassurance, clear communication, and continuity throughout pregnancy, particularly during complex or emotionally sensitive moments.

Dr Ling completed her fetal medicine fellowship at the internationally renowned Harris Birthright Research Centre, followed by further sub-specialist training at St George’s Hospital. She was awarded the prestigious Young Investigator Award by the International Society of Ultrasound in Obstetrics and Gynaecology (ISUOG) and holds a PhD for her research in maternal cardiovascular health. In addition to her clinical work, she is a Cardiff University Bond Solon (CUBS) medico-legal expert witness in obstetrics and an Associate Editor of The Obstetrician & Gynaecologist (TOG), a leading professional development journal for healthcare professionals.

As a mother of four, Dr Ling brings a deeply personal understanding of pregnancy and its physical and emotional demands. She believes women should feel genuinely heard, well informed, and supported in every decision. Her consultations combine advanced diagnostic ultrasound expertise with an unhurried, compassionate style that helps patients feel confident and cared for at every stage.

Fluent in English, Mandarin, Cantonese, and Malay, Dr Ling offers culturally sensitive care to women from diverse backgrounds. Her global upbringing shapes her inclusive practice, with meticulous ultrasound assessments, clear explanations, and dedicated time for questions.
