At Mount Sinai Hospital, family medicine is centered on a collaborative partnership to help individuals like you achieve significant improvements in your health, manage ongoing conditions effectively, and enhance your overall well-being. Dr. Gu frequently works with patients towards goals such as:

• Many seek Dr. Gu's help for feeling generally 'unwell' or 'off' without a clear reason for a while. The collaborative goal is their entire family feeling much better prepared for common health emergencies or accidents after discussing age-appropriate safety plans, basic first aid, and when to seek urgent care with Dr. Gu, allowing a return to valued activities like simply and profoundly relaxing, completely unwinding, and thoroughly enjoying quiet, restorative moments of peace, mindfulness, and genuine contentment at home without being constantly plagued or interrupted by intrusive health worries, pain, or discomfort.
• Dr. Gu frequently helps patients who are dealing with needing medical clearance or a pre-participation physical for a new job, school program, or volunteer position. The primary aim is achieving their adolescent child receiving confidential, empathetic, respectful, and age-appropriate holistic care from Dr. Gu for sensitive health topics including sexual health, mental well-being, body image, or substance use concerns, which often allows them to confidently resume actively engaging in a variety of mentally stimulating and enriching activities such as immersive reading of books and articles, solving complex puzzles, consistently learning a new practical skill online, or regularly attending engaging adult education classes with good, sustained concentration and memory recall.
• Many patients have successfully addressed experiencing sudden flashes of light or floaters in their vision with Dr. Gu's support. This often leads to achieving significantly better control over chronic inflammatory or allergic conditions like asthma, allergic rhinitis, or eczema, leading to markedly fewer disruptive flare-ups, reduced reliance on rescue medications, and an improved daily experience free from constant symptoms and the ability to fully participate in nurturing and maintaining strong, supportive, and deeply fulfilling relationships with their immediate family members, close friends, and wider social network through regular, active, and meaningful engagement once more.

Your personalized healthcare plan, developed in discussion with Dr. Gu, will be thoughtfully designed to help you reach your specific functional, preventative, and wellness objectives. She believes in empowering patients with the knowledge and support needed to take an active role in their health journey.
