A mirror can show your weight, shape and appearance.
It cannot show your blood pressure, blood sugar, cholesterol particles, visceral fat, sleep debt or the strain quietly accumulating inside your arteries.
This is particularly important for Indians and the broader South Asian population. Many people appear lean, remain active and feel completely well—yet may still carry meaningful cardiometabolic risk.
The lesson is not that every Indian is destined to develop heart disease.
It is that our risk may require a different level of awareness – and, for some people, an earlier conversation about prevention.
Looking healthy and being metabolically healthy are not always the same
We often judge health visually.
If someone is slim, we assume their blood sugar must be normal. If they exercise, we assume their cholesterol must be under control. If they have no symptoms, we assume their heart is healthy.
But cardiovascular risk rarely announces itself so clearly.
South Asian ancestry is recognised in cardiovascular guidance as a factor that may enhance risk. Studies have also found that South Asian adults can develop diabetes, high blood pressure and other cardiometabolic risk factors at younger ages.
This does not mean ethnicity alone determines a person’s future. Most of the increased risk appears to involve familiar factors—including insulin resistance, diabetes, blood pressure, abnormal lipids, abdominal fat, inactivity and tobacco exposure – interacting in different proportions.
The danger is assuming that a normal-looking exterior guarantees normal numbers.
BMI tells only part of the story
Body mass index can be useful at a population level, but it does not reveal where fat is stored or how that fat is behaving metabolically.
Two people with a similar BMI may have very different amounts of fat around their abdominal organs.
This deeper abdominal fat – known as visceral fat – is more closely connected with insulin resistance, abnormal triglycerides, fatty liver and cardiometabolic risk than appearance alone might suggest.
South Asian populations may develop type 2 diabetes and metabolic complications at lower BMI levels than some other populations. This is one reason diabetes-screening recommendations use a lower BMI threshold for people of Asian ancestry.
Your waist measurement may therefore add information that your weight cannot. The World Health Organization notes that measures of abdominal fat, including waist circumference and waist-to-hip ratio, can help predict diabetes and cardiovascular risk alongside BMI.
Being thin is not a diagnosis of metabolic health.
Sugar trouble can begin before symptoms do
Prediabetes and insulin resistance can develop quietly.
There may be no excessive thirst, obvious fatigue or dramatic change in weight. A person may feel normal while their glucose regulation is gradually worsening.
According to current American Diabetes Association criteria, the prediabetes range includes:
- HbA1c from 5.7% to 6.4%
- Fasting plasma glucose from 100 to 125 mg/dL
These numbers should always be interpreted by a qualified clinician in the context of the complete health picture.
A single result is useful, but a pattern is often more revealing.
Is fasting glucose gradually rising? Has HbA1c shifted over several years? Is the waistline increasing even though body weight looks stable? Are triglycerides climbing while HDL remains low?
Prevention begins when we notice the direction of travel—not only when a number finally enters the disease range.
The Indian heart story is not only about cholesterol
Cholesterol matters enormously, but heart risk should not be reduced to one LDL result.
A more complete discussion may include:
- Blood pressure
- Fasting glucose and HbA1c
- LDL and non-HDL cholesterol
- Triglycerides
- Waist circumference
- Smoking or tobacco exposure
- Sleep, movement and dietary habits
- Family history of premature heart disease or diabetes
For selected people, clinicians may also consider tests such as ApoB, which estimates the number of potentially artery-entering lipoprotein particles. Updated cardiovascular guidance also recommends measuring lipoprotein(a), or Lp(a), at least once in adulthood, because high levels are largely inherited and may influence lifetime risk. The need for these tests and their interpretation should be discussed with a clinician.
The purpose is not to order every available test.
It is to ensure that an apparently reassuring number does not distract from a concerning overall pattern.
The busy professional profile deserves attention
One commonly overlooked profile is the person who appears productive and functional but spends most of the day sitting.
Long workdays can bring a difficult combination:
- Prolonged sitting
- Irregular meals
- Refined-carbohydrate-heavy convenience food
- Insufficient movement
- Chronic stress
- Short or inconsistent sleep
None of these factors acts alone. Together, however, they can gradually influence blood pressure, insulin sensitivity, appetite, abdominal fat and recovery.
The American Heart Association includes sleep, physical activity, blood glucose, cholesterol, blood pressure, weight, diet and nicotine exposure among its essential measures of cardiovascular health. Adults are generally advised to aim for seven to nine hours of sleep and to reduce prolonged sedentary time by moving regularly.
A workout cannot make every other hour of the day irrelevant.
Your heart experiences the whole lifestyle—not just the hour spent exercising.
Family history should move the conversation earlier
A family history of premature heart disease, stroke, high cholesterol or diabetes does not guarantee the same outcome for you.
But it should change the questions you ask.
Family history may reflect inherited biology, shared behaviours and a shared environment. It gives your clinician important context when deciding when screening should begin and how aggressively modifiable risks should be addressed.
Knowing that heart disease “runs in the family” should not create fear.
It should create a plan.
What should you know about your own baseline?
There is no universal testing schedule for every person. Age, symptoms, pregnancy history, medications, family history and existing medical conditions all matter.
But most adults should be able to answer some basic questions:
Do I know my usual blood pressure—not just one reading taken during a stressful appointment?
When were my fasting glucose and HbA1c last checked?
Do I understand my complete lipid profile rather than only total cholesterol?
Has my waistline changed over time?
Am I routinely getting restorative sleep?
How much of my day is spent sitting?
Does premature heart disease or diabetes occur in my family?
Take these questions to your doctor and build a screening plan appropriate for your personal risk.
My take as a cardiac surgeon
Inside the operating room, disease is visible.
The narrowed artery, damaged vessel or struggling heart is no longer theoretical.
But the process often began years earlier—when the person still looked healthy, felt fine and had no obvious reason to worry.
That is why prevention matters more than appearance.
Do not wait to look unwell before becoming curious about your health.
Know your baseline.
Watch your trends.
Act while the story can still be changed.
The mirror reflects your appearance.
Your numbers reveal a different part of the story.
