South Asians – people who find themselves from or hint their ancestry to the Indian subcontinent, which incorporates India, Pakistan, Afghanistan, Bangladesh, Bhutan, and Nepal – are as much as 4 occasions extra prone to have type 2 diabetes than folks of different ethnic backgrounds. And lots of South Asians recognized with kind 2 diabetes have a standard weight and physique mass index (BMI).

WebMD: What led you to turn out to be an endocrinologist and direct your focus towards kind 2 diabetes?
Shariff: After medical faculty, I utilized and interviewed for nephrology [a medical specialty focused on the kidneys] after which modified paths to affix endocrinology after I bought recognized with gestational diabetes. Additionally, my father has had kind 2 diabetes since I used to be a child and since his early 40s, however a few years into me being an attending [physician] he began exhibiting a really totally different sample of diabetes. My journey began with my private story and ended with me diagnosing and caring for my very own father.
WebMD: Why do South Asians who’re skinny have a threat of kind 2 diabetes?
Shariff: That is as a result of now we have adipose tissue round our liver and our muscle that makes us insulin resistant. Name it visceral adiposity. It principally blocks the impact of insulin on these crucial constructions. Now, the mind and the muscle are two areas in your physique that actually do not want any insulin to uptake glucose. So … although individuals are exercising, they [can] develop insulin resistance and kind 2 diabetes [if] their muscle groups are usually not in a position to take in that blood sugar.
WebMD: How do BMI and insulin play a task in South Asians who’re recognized with kind 2 diabetes?
Shariff: Most of my sufferers who are available in with kind 2 diabetes are usually very wholesome. They’ve a standard BMI, they train, and so they nonetheless can not perceive why they cannot budge that A1c.[Editor’s note: The hemoglobin A1c test checks your average blood sugar level for the past 2-3 months. A normal A1c level is below 5.7%. An A1c level of 5.7% to 6.4% is in the prediabetes range. And 6.5% or higher is in the diabetes range. You’d get that checked twice before diagnosing diabetes.]
A very good instance is myself; I’ve a low BMI but I took 40 items of insulin once I was pregnant [and had gestational diabetes].
Sometimes when you’ve got kind 2 diabetes, you’ve got insulin resistance. You’ve gotten numerous insulin, however it would not work as nicely. So that you require an entire lot extra insulin to do the job of what it ought to have finished with out the resistance.
South Asians have each insulin resistance and insulin deficiency. [One theory says that] Inherently as a race now we have beta cell dysfunction, or what we name beta cell blunting. While you eat a meal, your sugar goes up, goes to the pancreas, and tells it to launch insulin. You require a a lot larger quantity of blood sugar to launch insulin and your beta cells are usually not as lively as they need to be.
WebMD: If somebody of South Asian descent goes to their main care physician, what threat elements necessitate screening for kind 2 diabetes?
Shariff:
- A BMI higher than 23. [Editor’s note: This is below the BMI threshold for being overweight.]
- Any first-degree relative [parent, child, or sibling] that has kind 2 diabetes
- Another member of the family who has kind 2 diabetes plus a historical past of coronary heart illness, hypertension, and triglycerides higher than 250
- Females who’ve a historical past of polycystic ovary syndrome (PCOS)
WebMD: How can somebody of South Asian descent advocate for themselves to get examined for kind 2 diabetes at their main care physician’s workplace?
Shariff: It’s essential that South Asians advocate for themselves and inform their main care doctor, “I perceive that you’d usually not have gotten an A1c in somebody like me, however as a result of I am South Asian, my threat is way larger at a decrease BMI and I am at a better threat for having kind 2 diabetes. For this reason it is best to display me.”
WebMD: How do you counsel your sufferers concerning weight loss plan and train?
Shariff: I by no means say it’s essential cease consuming one thing [if you have] diabetes, which is a breath of contemporary air for many sufferers. I say, ‘I need you to grasp what you may eat much less of and what you have to be consuming extra of and the right way to steadiness your weight loss plan.’
Many South Asians are vegetarian and it’s a heavy carb weight loss plan. No matter kind of carb you’re going to eat, it’s going to boost your blood sugar. Attempt to keep true to your flavors and be inventive with how one can modify the carb parts of your meals into much less carbohydrates, or excessive fiber, excessive protein choices.
Typically folks train and different occasions they don’t. I put 70% emphasis in your weight loss plan. In case you eat meals that work along with your prognosis of diabetes, your sugars are going to be higher. This enables your insulin resistance to come back down.
WebMD: What message do you need to ship South Asians concerning a kind 2 diabetes prognosis?
Shariff: It’s important to steadiness sustainability and perceive it’s essential search assist. You don’t need diabetes to outline you.
