G.D. Hospital & Diabetes Institute (GDDI) is a 150-bed multispecialty tertiary care hospital in Kolkata — and Eastern India’s first diabetes-dedicated hospital. Located at 139A, Lenin Sarani, it brings together advanced diabetes care and over 20 clinical specialties under one roof. If you’re looking for OPD timings, contact details, available services, or how to book an appointment, this guide covers everything you need before your visit.
What Is G.D. Hospital & Diabetes Institute?
G.D. Hospital & Diabetes Institute (GDDI, also called GDHDI) is a 150-bed multispecialty tertiary care hospital located at 139A, Lenin Sarani, Kolkata — 700 013, West Bengal. It is part of the Pataka Group and is widely recognised as the first diabetes-focused hospital of its kind in Eastern India, with over 14 years of clinical service.
The hospital operates as a fully integrated facility. This means a diabetes patient can receive not only diabetology care but also cardiology, nephrology, ophthalmology, orthopaedic, neurological, and surgical treatment in the same building — without being referred out. This is especially significant for people with diabetes, who frequently need coordinated care across multiple specialties to manage complications.
GDDI is equipped with a 14-bed ultramodern ICU, a Neonatal Intensive Care Unit (NICU), a Special Care Baby Unit (SCBU), three operation theatres, and a dedicated labour room. Emergency services, ambulance support, and a 24-hour pharmacy are available round the clock. The hospital also accepts cashless treatment through TPA and major health insurance providers.
Note: GDDI is a tertiary care hospital, which means it handles complex and specialised conditions in addition to routine outpatient care.
It is well suited for patients managing diabetes with multiple complications.
Diabetes Care at GDDI: What Sets It Apart
GDDI’s founding purpose was to address the growing burden of diabetes in Eastern India, and its clinical programmes reflect that focus in two key ways: structured monitoring panels and multi-specialty diabetes complication management.
Diabetes Monitoring Panels
The hospital offers two dedicated monitoring packages:
- GD Executive Diabetes Monitoring Panel — A comprehensive screening package for working professionals who need structured, periodic monitoring. It typically covers blood glucose (fasting and post-meal), HbA1c, kidney function markers, lipid profile, liver function, and urine analysis.
- GD Diabetes Monitoring Panel — A standard panel covering the essential tests for ongoing diabetes management.
Both panels are designed for patients who require structured follow-up rather than one-off consultations. They are useful for anyone newly diagnosed with diabetes, or for those whose current monitoring is inconsistent.
Diabetes Complication Specialties Under One Roof
Diabetes is a systemic disease — its complications touch the eyes, kidneys, heart, nerves, and feet. At GDDI, the specialties that directly overlap with diabetes complication management include:
- Ophthalmology — for diabetic retinopathy screening and treatment
- Nephrology — for diabetic kidney disease management; dialysis is available in multiple shifts
- Cardiology and Cardiovascular Surgery — for heart disease, which is significantly more prevalent in people with diabetes
- Foot Care Clinic — for diabetic foot assessment and wound management
- Dietetics — for personalised nutritional planning and meal management
- Physiotherapy and Sports Rehabilitation — for mobility and neuropathy-related issues
- Neurology — for peripheral neuropathy and other neurological complications
Note: If you are managing diabetes and being referred to a specialist, ask your diabetologist about coordinated referrals within the hospital.
GDDI’s integrated model is designed to reduce the need to visit multiple hospitals for diabetes-related complications.
