Dr. Mamta Singh, MD
- Board-Certified Internal Medicine | Obesity Medicine & Geriatric Medicine
Dr. Mamta Singh is a U.S.-trained Internal Medicine physician with advanced dual specialization in Geriatrics and Obesity Medicine, offering a comprehensive approach to metabolic health, longevity, and healthy aging. She brings over a decade of clinical experience to Oasis Medical Group Cayman Ltd.
During her medical career in the United States, Dr. Singh practiced as both a primary care physician and a geriatric consultant, collaborating closely with hospitals and primary care providers to manage complex and high-risk patients. She has cared for individuals across the lifespan—from adolescents to older adults—with a strong focus on personalized, evidence-based care.
