Normal BP Fluctuations

 1. Normal BP Fluctuations

Blood pressure is dynamic, not static — it changes minute to minute depending on what your body is doing.
Common reasons for a 30 mmHg jump in the same day include:

• Physical activity – Walking fast, climbing stairs, or carrying groceries can raise BP temporarily.

• Stress or anxiety – Even a stressful meeting or traffic jam can push systolic BP 20–40 points higher.

• Caffeine or nicotine – Can cause a short-term spike.

• Meals high in salt – Especially if eaten at lunch, may push BP up in the afternoon.

• Pain or illness – Fever, headache, or even dehydration can elevate BP.

• Time of day – BP usually peaks mid-morning & late afternoon, and is lowest during sleep.

---

2. When It’s Still Considered “Normal”

• If your BP is mostly in the 120–130/80–85 range but occasionally rises to 140–150 systolic during stress or activity, and then drops back down within an hour, that’s usually a normal physiological response.

• Occasional spikes don’t mean you have uncontrolled hypertension — but they can signal BP sensitivity.

---

3. When to Be Concerned

You should check with a doctor if:

• Your BP stays above 140/90 most of the time.

• Spikes are frequent and happen even when you’re calm, rested, and hydrated.

• You have symptoms during the spike: headache, dizziness, blurred vision, chest discomfort, or shortness of breath.

• The systolic number exceeds 180 (hypertensive crisis — seek urgent care).

---

4. How to Check If Spikes Are a Problem

• Home monitoring: Measure at least twice daily — once in the morning before food/coffee, once in the evening, both at rest.

• Record patterns: Note time, activity, food/drink before the reading, and stress level.

• Discuss averages with your doctor — doctors rely more on consistent readings than on one-off highs.

How to Use

1. Measure twice daily:

   • AM – after waking, before eating/drinking, after sitting quietly 5 min

   • PM – before dinner, after sitting quietly 5 min

2. Use correct posture: Back supported, feet flat, arm at heart level, no talking during measurement.

3. Record any factors before the reading (coffee, salty meal, exercise, stress).

4. Note symptoms if any occur during high readings.

Interpretation Guide (Adults)

Category	Systolic (mmHg)	Diastolic (mmHg)	What It Means
Normal	<120	<80	Healthy range
Elevated	120–129	<80	Monitor, lifestyle care
High BP Stage 1	130–139	80–89	Discuss with doctor
High BP Stage 2	140–179	90–119	Likely needs treatment
Hypertensive Crisis	≥180	≥120	Seek emergency care

---

Tip: Doctors focus on average BP over days, not single spikes.
If your average is >135/85 at home, that suggests possible hypertension.

Hypertension Prevalence Among Adults in Singapore

 Hypertension Prevalence Among Adults in Singapore

• According to the National Population Health Survey (NPHS) 2022, the prevalence of hypertension among Singapore residents aged 18–74 was 37.0%, up from 35.5% in 2019–2020 Ministry of Health.

• In more familiar terms, that means more than 1 in 3 Singaporean adults have high blood pressure. This aligns with other sources stating over one in three residents aged 18 to 74 have hypertension MyHeartHealthHub.

---

Estimating the Actual Number of Adults

• As of mid-2024, Singapore’s total population stood at approximately 6.04 million, of which 4.18 million are residents (citizens + permanent residents) Wikipedia.

• Using the 37.0% prevalence rate for adults 18–74, the estimated number of adult residents with hypertension would be:

  4.18 million × 37% ≈ 1.55 million adults
  

So roughly 1.5 million adult residents in Singapore are likely affected by hypertension.

---

Summary

Metric	Value
Prevalence of adult hypertension (18–74 years)	37.0% (2021–2022)
Estimated number of affected adult residents	Approximately 1.55 million

---

Hypertension by Age Group (NPHS 2022)

• The prevalence of hypertension increased to 37.0% among residents aged 18 to 74 during the period July 2021–June 2022, up from 35.5% in 2019–2020 Ministry of Health+1.

• This rise was especially observed among those aged 50 to 74 years — even after adjusting for Singapore’s population aging Mothership.

• Unfortunately, the NPHS press release does not provide more granular age-decile breakdowns (e.g., 18–29, 30–49), but it’s clear the older adult group bears a higher burden.

---

Hypertension by Ethnicity and Gender

• The NPHS 2022 report doesn’t provide demographic details like gender or ethnicity breakdowns.

• However, earlier data from the National Health Survey 2010 (pre-NPHS) shows disparities across ethnic groups:

  • Chinese: ~23.4% prevalence

  • Malay: ~28.0%

  • Indian: ~19.3% PMC+1

• These older findings still highlight that Malays had a notably higher hypertension prevalence than Chinese and Indians.

• No updated breakdowns by ethnicity or gender were available in the 2022–2023 NPHS press coverage.

---

Summary Table

Demographic Segment	Hypertension Prevalence
Residents (18–74 years)	37.0% (2021–2022) Ministry of Health+1
Age 50–74	Higher prevalence, key driver of increase Mothership
Ethnicity (2010 data)	Malay: ~28%, Chinese: ~23%, Indian: ~19% PMC+1

---

What This Means

• Hypertension affects over 1 in 3 adult residents in Singapore.

• The risk increases significantly with age, particularly from 50 years onwards.

• Though somewhat dated, ethnicity-related data from 2010 suggests Malays were disproportionately affected—even then.

---

Available Data Summary

Overall Trend (Residents Aged 18–74)

• The National Population Health Survey (NPHS) 2022 reported that the prevalence of hypertension rose from 19.8% in 2010 to 35.5% in 2019–2020, and further up to 37.0% in 2021–2022, even after adjusting for population ageing Ministry of HealthHealthHub.

• While the NPHS 2023 exists, the public summary doesn’t include updates on hypertension prevalence or breakdown by age/gender/ethnicity Ministry of Health+1Health Promotion Board.

Ethnic Differences (Older Data)

• The 2010 National Health Survey (precursor to NPHS) found differences in hypertension prevalence by ethnicity:

  • Chinese: ~23.4%

  • Malay: ~28%

  • Indian: ~19.3% PMC.

Ethnicity & Age Trends (Research Studies)

• A 2023 study (via PMC) noted a rise in age-standardised hypertension prevalence—from 21.9% in 2017 to 31.7% in 2020. It also highlighted that Malay and Chinese individuals experienced a greater increase compared to Indians PMC.
