There is an uncomfortable truth that many Vietnamese Americans need to know: our community has higher rates of type 2 diabetes, high blood pressure, and cardiovascular disease than average — and we often discover them later and treat them less frequently.
Not because Vietnamese people are "weaker." But because there are very specific barriers: language barriers, the habit of not getting regular checkups, the belief that "if it doesn't hurt, there's no need to see a doctor," and both genetic factors and diet.
This article will explain what these three diseases are, why Vietnamese people need to pay special attention, and — most importantly — what to do to prevent them starting now.
What are these three "silent enemies"?
We call them "silent enemies" for good reason: all three can progress for years without obvious symptoms. By the time you feel "something is wrong," you're usually already in a serious stage.
High Blood Pressure (Hypertension)
Blood pressure is the force of blood pushing against artery walls. Normal is below 120/80 mmHg. When this number exceeds 130/80 mmHg and stays there, you've entered dangerous territory.
Think of it this way: your blood vessels are like a water pipe. If water pressure is continuously too high, the pipe wall gets damaged, tends to leak, and could eventually burst. That's why high blood pressure leads to stroke and heart attack.
Type 2 Diabetes
Our bodies use insulin (a hormone produced by the pancreas) to move glucose (sugar) from the blood into cells. With type 2 diabetes, the body either doesn't produce enough insulin, or cells "resist" insulin — meaning they don't respond properly anymore.
Result: sugar accumulates in the blood, and over time damages blood vessels, kidneys, eyes, and nerves.
Cardiovascular Disease
This is a group of diseases related to the heart and blood vessels, including heart attack, stroke, heart failure, and atherosclerosis — fat buildup inside artery walls.
It's important to understand: high blood pressure and diabetes are both major risk factors for cardiovascular disease. These three diseases are not separate from each other — they're linked like falling dominoes.
Why do Vietnamese people have particularly high risk?
Research from the U.S. Centers for Disease Control and Prevention (CDC) and many community studies show that Asian Americans — especially Southeast Asians — have certain characteristics that make these three diseases appear more frequently.
1. "Normal" BMI but high visceral fat
This is the point where many Vietnamese people are most "deceived." East Asians tend to accumulate fat around the organs (visceral fat) even when their weight appears normal. Someone weighing 132 pounds who doesn't look obese might have a high abdominal fat percentage — and that's the most dangerous type of fat for the heart and pancreas.
Therefore, the warning threshold for East Asians is lower than for white people: a BMI of 23 or higher is already considered overweight for Asians.
2. Diet high in white carbohydrates
White rice, bread, noodles, pho — all familiar Vietnamese dishes are refined carbohydrates that cause blood sugar to spike quickly. Eating like this for many years causes the pancreas to overwork, and diabetes risk gradually increases.
3. Little physical activity after immigration
In Vietnam, walking, cycling, and farming are daily activities. When coming to America, many people switch to driving to work, sitting in offices, or standing in nail salons all day — all sedentary lifestyles.
4. Genetic factors
If your parents, parents, or siblings have diabetes or high blood pressure, your risk increases significantly. This is a factor we can't change — but knowing early so we can prevent is still worthwhile.
5. Barriers to healthcare access
No health insurance, not speaking English, being afraid to see a doctor because of cost concerns, or simply "too busy" — all lead to late disease detection and late treatment.
Early recognition: The numbers you need to know
You don't need to be a doctor to understand your own health. Just remember a few important numbers:
| Measure | Normal | Warning | Danger |
|---|---|---|---|
| Blood Pressure (mmHg) | Below 120/80 | 120 to 129 / below 80 | 130/80 or higher |
| Fasting Blood Sugar (mg/dL) | Below 100 | 100 to 125 (prediabetes) | 126 or higher (diabetes) |
| HbA1c (%) | Below 5.7 | 5.7 to 6.4 | 6.5 or higher |
| BMI (East Asians) | Below 23 | 23 to 27.4 | 27.5 or higher |
| LDL Cholesterol (mg/dL) | Below 100 | 100 to 159 | 160 or higher |
What is HbA1c? This is a test that measures average blood sugar over the past 3 months — more accurate than measuring blood sugar at one point in time because it reflects the "big picture.
Prevention: No need for medication or fancy gym memberships
The good news is: most of the risk of getting these three diseases can be significantly reduced just by changing your lifestyle. You don't need to change everything at once — just small steps, maintained over time.
Diet: Adjust, don't give up everything
No one is telling you to quit pho or beef noodles. But you can adjust:
- Reduce white carbs, increase complex carbs
- Replace some white rice with brown rice, eat more sweet potatoes and whole grains. You don't need to eliminate it completely — just eating one less bowl of rice per meal makes a difference.
- Eat more vegetables, protein, and healthy fats
- Green vegetables, fish (especially salmon and mackerel rich in omega-3), tofu, skinless chicken — these foods protect your heart. Olive oil, avocado, and cashews are also good sources of healthy fats.
- Reduce salt — especially in fish sauce, soy sauce, and instant noodles
- Vietnamese people consume more sodium than recommended because fish sauce, soy sauce, and salty broth are central to meals. Blood pressure is very sensitive to sodium. Goal: below 2,300 mg of sodium per day (about one teaspoon of salt).
- Limit sweets and sugary drinks
- Boba tea, soft drinks, sweet tea — these cause blood sugar to spike. You don't need to cut them completely, but drinking them regularly every day is a big problem.
Exercise: 30 minutes a day — that's enough
You don't need to run a marathon. Research shows that brisk walking for 30 minutes daily, 5 days a week, significantly reduces the risk of diabetes and high blood pressure.
If you stand in a nail salon all day or sit at a desk — after work, take a walk around your neighborhood, take the stairs instead of the elevator, or do light yoga for 20 minutes before bed. It all adds up.
Tips for busy people:
-
Park farther away and walk into the supermarket
-
Walk to the mailbox instead of driving
-
Exercise lightly while watching a movie or YouTube video
-
Invite family to take an evening walk — exercise and chat at the same time
Manage stress
Few people mention this, but chronic stress increases the hormone cortisol — this hormone raises blood pressure, raises blood sugar, and accumulates belly fat.
Many Vietnamese in America carry enormous burdens: worrying about family in Vietnam, rent, children's education, jobs. All of this adds up to persistent pressure.
There's no magic solution, but: get 7 to 8 hours of sleep each night, make time for things you enjoy, and don't hesitate to talk to someone when you feel overwhelmed — including a mental health professional (therapist or counselor).
Don't smoke, limit alcohol
Tobacco is the biggest risk factor for cardiovascular disease — doubling the risk of heart attack. Drinking a lot of alcohol raises blood pressure and blood sugar.
If you're smoking and want to quit, talk to your doctor about support programs — many states have free programs.
Regular screenings: Don't wait until you have symptoms
This is the most important thing the Vietnamese community needs to change in their mindset: you go to the doctor not just when you're in pain. Regular screening is to detect disease before it causes harm.
| Test | Who should do it | Frequency |
|---|---|---|
| Blood Pressure Check | All adults 18 and older | At each checkup or at least once a year |
| Blood Sugar and HbA1c Test | People 35 and older, or at risk | Once every 3 years if normal |
| Cholesterol Test (Lipid Panel) | Men 35 and older, women 45 and older | Once every 5 years if normal |
| EKG and Cardiovascular Assessment | People at high risk or with symptoms | As directed by doctor |
If you're on Medicaid, Medicare, Covered California or similar insurance programs in your state, many of these tests are free or very low cost.
No insurance? Many Vietnamese communities have community health centers with sliding scale fees based on income. Search for "federally qualified health center" near you at findahealthcenter.hrsa.gov.
When you already have the disease: Management, not surrender
If you've been diagnosed with high blood pressure, diabetes, or have cardiovascular issues — this is not a life sentence. Millions of people live healthy, long-term lives with these conditions when properly managed.
Take medicine exactly as prescribed — don't stop on your own
One of the most common mistakes: patients see "normal" readings and stop blood pressure medication thinking they're cured. That's not how it works. The medicine is keeping the readings normal — stopping it means the readings will go back up.
Always ask your doctor before changing doses or stopping medicine.
Monitor at home
Buying a blood pressure monitor at home isn't expensive — about 30 to 50 dollars at Walmart or Amazon. A glucose meter is the same. Keep records and bring the results to your doctor.
Build a support group
Talk to family about your health condition. When loved ones know about your illness, they can support you better — from cooking low-salt meals to reminding you to take medicine.
Common misconceptions in the Vietnamese community
❌ "I look thin, I can't have diabetes."
As explained, Vietnamese people can have high visceral fat even if they look thin. Outward weight doesn't fully reflect risk.
❌ "Taking traditional Vietnamese and Chinese medicine is enough."
Some herbs have supportive effects, but they can't replace Western medicine when the disease is at the level requiring treatment. Even more dangerous, some herbs can interact with Western drugs — tell your doctor about everything you're taking.
❌ "My high blood sugar is because I eat a lot of sugar — avoiding sugar will cure it."
Type 2 diabetes is more complex. Carbohydrates in general — not just sugar — all affect blood sugar. And once you're at the diabetes stage, just avoiding sugar isn't enough.
❌ "High blood pressure causes headaches, no headache means nothing's wrong."
The truth: most people with high blood pressure have no symptoms until serious complications like stroke occur. That's why it's called a "silent killer.
❌ "This is a disease of old people, I'm still young why worry."
Type 2 diabetes is increasingly common in young people. The same with high blood pressure. Habits formed in youth — good or bad — will affect your health 20 to 30 years later.
Support resources for the Vietnamese community
You don't have to face these challenges alone. Some helpful resources:
-
Asian community clinics: Many cities with large Vietnamese populations like Houston, San Jose, Orange County, and Los Angeles have community clinics with Vietnamese-speaking staff.
-
Asian Health Coalition and similar organizations: Provide health information in Vietnamese and connect to healthcare services.
-
Diabetes Prevention Program (DPP): A CDC program for people with prediabetes, many locations have Vietnamese-language versions. Search on the CDC website.
-
1-800-QUIT-NOW: Free smoking cessation helpline with interpretation services.
Where to start? Three first steps this week
If you don't know where to start, do these three things first:
- Step 1: Schedule a general checkup (annual physical) if you haven't had one in over a year. Tell your doctor you want to check blood pressure, blood sugar, and cholesterol.
- Step 2: Ask family members if anyone has diabetes, high blood pressure, or heart disease. Family history is important information your doctor needs.
- Step 3: Choose one small change in diet or exercise to start this week. Just one — small — but start now.
- Health is not something we can postpone worrying about. With these three diseases, timing really matters — early detection and early change can make a huge difference between a healthy life and years of struggling with complications.
- Take care of yourself — so you can continue taking care of your loved ones around you.
