Chapter 14: Hypertension and Special Populations

Understanding Unique Risks and Care Across All Ages

While hypertension is most common in middle-aged and older adults, it can affect people at every stage of life—including pregnant women, seniors, children, and teens. Each of these populations has unique risk factors, symptoms, and treatment needs. Managing high blood pressure in these groups requires extra care, specialized monitoring, and often, tailored lifestyle and medication strategies.

In this chapter, we explore:

The serious implications of high blood pressure during pregnancy
The importance of careful blood pressure control in older adults
The surprising rise in hypertension in young people—and what parents can do

1. High Blood Pressure in Pregnancy (Preeclampsia and Gestational Hypertension)

High blood pressure during pregnancy isn’t just a maternal issue—it can put both mother and baby at risk. It’s one of the leading causes of complications during pregnancy and can lead to serious, even life-threatening outcomes if not properly managed.

Types of Hypertension During Pregnancy:

Chronic hypertension – High blood pressure that existed before pregnancy or develops before 20 weeks gestation
Gestational hypertension – High BP that develops after 20 weeks, without signs of organ damage
Preeclampsia – High BP after 20 weeks with signs of organ involvement (like protein in urine or liver problems), which can lead to seizures (eclampsia)

Risks of Untreated Hypertension During Pregnancy:

Preeclampsia and eclampsia
Preterm delivery
Low birth weight
Placental abruption (a serious complication where the placenta separates from the uterus)
Organ damage in the mother (liver, kidneys, brain)

Signs to Watch For:

Swelling in the hands and face
Sudden weight gain
Headaches that don’t go away
Blurred vision or visual changes
Upper abdominal pain
Shortness of breath

Important: Pregnant women should have regular prenatal checkups with blood pressure monitoring at every visit.

Management Strategies:

Close monitoring and more frequent prenatal visits
Safe blood pressure medications (like labetalol or methyldopa)
Reduced sodium intake and moderate activity
Bed rest in severe cases
Delivery may be recommended early if complications develop

Preeclampsia requires immediate attention and should be treated as a medical emergency if symptoms escalate.

2. Managing Hypertension in Seniors

High blood pressure becomes more common with age due to natural changes in the arteries, such as stiffening and narrowing. In fact, over 70% of adults over age 65 have hypertension.

Unique Challenges in Seniors:

Isolated systolic hypertension is common (elevated systolic, normal diastolic)
Higher risk of side effects from medications, like dizziness, electrolyte imbalances, or kidney strain
Greater chance of coexisting conditions, such as diabetes, heart disease, or cognitive decline
Falls and balance issues related to low diastolic pressure or overly aggressive treatment

Balance is key—treat high blood pressure without dropping it too low, which can reduce blood flow to the brain and kidneys.

Recommended Approach:

Target BP for seniors: Usually around 130/80 mmHg, unless other health issues suggest a different range
Use low doses of medication and monitor closely
Emphasize lifestyle adjustments (walking, DASH diet, stress reduction)
Monitor for orthostatic hypotension—a sudden drop in BP when standing up
Encourage hydration, mobility, and safe physical activity

Tips for Caregivers and Family:

Help track medications and BP readings
Attend doctor appointments when possible
Support lifestyle changes through shared meals and activities
Watch for changes in mood, cognition, or energy levels

Goal: Preserve quality of life while protecting the brain, heart, and kidneys.

3. High Blood Pressure in Children and Teens

Although less common, hypertension is on the rise in young people, largely due to increases in childhood obesity, poor diet, and inactivity. High BP in youth is especially dangerous because it often continues into adulthood—and may cause early organ damage.

Causes in Youth:

Primary hypertension – Usually linked to lifestyle and genetics
Secondary hypertension – May be caused by underlying conditions like kidney disease, heart defects, or endocrine disorders

Risk Factors:

Overweight or obesity
Family history of hypertension
Poor diet (high in processed foods, salt, and sugar)
Sedentary lifestyle and excessive screen time
Sleep apnea or chronic stress

Warning Signs (Often Subtle):

Headaches
Nosebleeds
Fatigue
Dizziness or trouble concentrating
Shortness of breath with activity

Regular checkups are essential. Blood pressure screening should start by age 3, or earlier if risk factors are present.

Diagnosis and Management in Kids:

BP readings are compared to standardized percentile charts based on age, sex, and height
Lifestyle changes are the first line of treatment:
- Balanced diet (reduce sugar and sodium)
- More physical activity (at least 60 minutes/day)
- Weight management
- Better sleep habits
In more severe cases or when underlying health conditions are present, medications may be used (under pediatric supervision)

Tips for Parents:

Lead by example with healthy habits
Limit sugary drinks, processed snacks, and fast food
Encourage outdoor play and family walks
Reduce screen time and build in relaxation or mindfulness time
Work with pediatricians or pediatric dietitians as needed

The earlier hypertension is addressed in youth, the greater the chance of full reversal.

Final Thoughts: One Condition, Many Faces

Hypertension doesn’t look the same for everyone. Whether you’re pregnant, aging, or caring for a child, blood pressure management must be individualized and proactive. Awareness, early detection, and targeted support can make all the difference.

The key across all populations is education, empowerment, and consistent care—because your heart health matters at every stage of life.
