Oman’s diabetes numbers are not a minor statistic. Roughly 15% of the population lives with diabetes, according to the Ministry of Health, with more than 6,500 new cases diagnosed every year. A 2025 study looking at diabetes patients in Oman’s peripheral regions found diabetic retinopathy was the leading complication at 22% of cases, followed by diabetic nephropathy at 13%, with over 60% of patients showing poor glycemic control (HbA1c above 9%) at registration.
That’s the real backdrop behind why so many Omani patients end up looking beyond general diabetes management toward specialist complication care — and why India, specifically, keeps coming up in that search.
This isn’t a generic “India has good hospitals” pitch. The reason India shows up so consistently for diabetic complications specifically is that it has built some of the world’s highest-volume, most specialized centers for exactly the three complications that hit hardest: diabetic foot disease, diabetic nephropathy, and diabetic retinopathy. Here’s what that specialization actually looks like.

Diabetic Foot Care: Where Volume and Specialization Matter Most
Diabetic foot complications are one of the most time-sensitive and outcome-dependent areas in diabetes care — the gap between a wound clinic that sees a handful of cases a month and one that sees them constantly can be the difference between limb salvage and amputation. Chennai’s M.V. Hospital for Diabetes is a specific example of what dedicated volume looks like: its chief diabetologist, Dr. Vijay Viswanathan, holds a PhD specifically in diabetic nephropathy and is a founding member of the international Diabetic Foot Study Group.
In 2024, the hospital launched a dedicated Wound Clinic Training Program focused on preventing diabetic foot infection complications, and partnered with the US-based Academy of Physicians in Wound Healing to establish a School of Podiatry under the name Diabetic Foot Research India — a sign of how much institutional weight has gone into this single complication area specifically, rather than diabetes care in general.
Dr. Mohan’s Diabetes Specialities Centre, also headquartered in Chennai, takes a similar dedicated-department approach: its Foot Clinic operates as a distinct unit within a network that has grown to roughly 50 centers across India and serves over 800,000 registered patients. The center is recognized as an International Diabetes Federation (IDF) Centre of Excellence, and its founder, Dr. V. Mohan, was awarded the Padma Shri — one of India’s highest civilian honors — for his work in diabetes care.
Diabetic Nephropathy: Volume-Driven Transplant and Dialysis Programs
Diabetic nephropathy is the complication most likely to eventually require dialysis or transplant, and this is where India’s major private hospital networks have built substantial specialized capacity. Medanta in Gurgaon, for example, performs over 250 kidney transplants a year and has developed robot-assisted transplant techniques aimed at shorter recovery periods — a relevant detail for patients weighing not just the surgery itself but the total time away from home and work.
Apollo’s nephrology network similarly publishes research specifically on managing diabetic nephropathy and reports tens of thousands of dialysis procedures annually across its hospital system.
For patients whose diabetic kidney disease hasn’t yet reached transplant stage, this same institutional depth applies to earlier-stage management too — nephrologists trained specifically in diabetic and hypertensive nephropathy management, CKD staging, and dialysis-access planning are part of the standard specialist bench at these centers, not a rare subspecialty referral.
Diabetic Retinopathy: A Research-Driven Approach to Vision Preservation
This is arguably where India’s specialization is most globally recognized. Sankara Nethralaya in Chennai, founded in 1978, was rated among the top four ophthalmic institutions worldwide by Newsweek in 2020. Its vitreoretinal department alone performs an average of about 500 retinal surgeries a month.
What sets it apart for diabetic patients specifically is that it isn’t just a high-volume surgical center — it’s also run the SN-DREAMS series of studies (I, II, and III), some of the most cited epidemiological research on diabetic retinopathy in South Asia, with retina specialists like Dr. Rajiv Raman contributing directly to both the clinical program and the underlying research on how the disease progresses and how screening should work. For a patient with early-stage retinopathy, that combination — clinicians who also research the disease’s progression patterns in South Asian populations specifically, a patient group that shares much of Oman’s own regional diabetes risk profile — is a meaningfully different starting point than a general ophthalmology department.
Why This Matters More for Complications Than for Diabetes Itself
Diabetes management day-to-day can happen almost anywhere with a competent endocrinologist. Complications are different — they’re where sub-specialization, surgical volume, and dedicated research infrastructure start to matter in ways that show up in real outcomes. A wound clinic that has trained 20+ vitreoretinal fellows, or a transplant program running 250+ cases a year with its own robotic protocol, or a foot clinic built around a founding member of an international diabetic foot study group — these aren’t marketing claims, they’re structural indicators of how much a given institution has organized itself specifically around a single complication rather than diabetes broadly.
What to Actually Look For When Comparing Options
- A named specialist with a specific sub-specialty credential in the exact complication you’re dealing with — diabetic foot, diabetic nephropathy, or vitreoretinal surgery — rather than a general diabetologist or general ophthalmologist.
- Case volume in that specific complication, not just overall hospital size. A large multi-specialty hospital with an occasional diabetic foot case is a different proposition than a dedicated foot clinic seeing cases daily.
- Research or training output tied to the complication — published studies, fellowship programs, or specialist training initiatives are a reasonable proxy for institutional depth in that area.
- How early-stage your case is. Retinopathy and nephropathy in particular have very different treatment pathways depending on stage — get a clear, written assessment of your stage before comparing destinations, since it changes which specialist and which type of intervention you actually need.
A Note on Timing
Given how much diabetic complications compound over time — retinopathy that’s manageable with laser treatment today can progress to a much more complex surgical case in a year, and nephropathy follows a similar trajectory — the most consistently useful advice from specialists in this field is the same one that gets repeated and still gets missed: don’t wait for the complication to become urgent before seeking a specialist opinion. Screening and early intervention change the entire calculus of what treatment abroad even needs to involve.
