The Compass
Your Monthly Guide to Better Health
August 2026 | Access • Convenience • Comprehensive Care
Restoring the doctor-patient relationship and putting the focus back on you.
A Message From Your Physician
August is a month of transition. Children return to school, families settle back into routines, and many of us begin preparing for the busy fall season. It is also one of the best times of year to focus on prevention.
Whether it is scheduling annual physicals, updating vaccines, reviewing medications, or establishing healthy habits, small steps now can make a big difference in the months ahead.
My goal remains simple: to provide accessible, convenient, relationship-based care that keeps you healthy—not just when you are sick, but every day in between.
Thank you for allowing me to be part of your healthcare journey.

🧭 NORTH-Prevention Corner
✔ Readiness for Fall/School:
Schedule a wellness visit
Review medications
Update vaccines:
Schedule cancer screenings
✔ Infection Prevention:
Vaccination: Influenza, Covid-19, Pneumococcal, RSV, Shingles vaccine
✔ Cancer Screening:
Colon Cancer Screening: Optimal strategy; colonoscopy usually every 5-10 years starting at age 45. When was the last time you had this completed?

One Small Change This Month?
Research consistently shows that long-term health is built through small, sustainable habits—not drastic changes or short-term diets. By focusing on a few foundational behaviors, you can improve your energy, mood, immune system, heart health, and overall well-being.
😴 Start with Sleep
Sleep is one of the most overlooked aspects of good health.
Adults should aim for 7–9 hours of sleep each night, while children and teenagers generally need even more.
Consistently getting enough sleep has been linked to:
✔ Better concentration and memory-clearing out brain toxins
✔ Improved mood and mental health
✔ Stronger immune function
✔ Lower blood pressure
✔ Better blood sugar control
✔ Reduced risk of heart disease and obesity
Tips for Better Sleep
• Go to bed and wake up at the same time—routines matter
• Turn off televisions, tablets, and phones at least 30 minutes before bedtime, prepares your brain to shut off/rest.
• Keep your bedroom cool, dark, and quiet, no TV watching in bed.
• Avoid caffeine after lunch if you're having trouble sleeping.
🥗 Fuel Your Body with Real Food
Healthy eating doesn't have to be complicated.
Instead of focusing on what to avoid, try building each meal around whole, minimally processed foods.
A simple guideline is the "Healthy Plate" approach:
🥦 ½ of your plate: Vegetables and fruit
🍗 ¼ of your plate: Lean protein such as chicken, fish, beans, eggs, or tofu
🌾 ¼ of your plate: Whole grains like brown rice, oats, or whole wheat pasta
💧 Water should be your primary beverage throughout the day. Commit to no added sugar beverages. No sugar in the coffee/tea, no soda, drink sparkling water instead.
Easy Changes That Make a Difference
✔ Choose fruit instead of chips for one snack each day.
✔ Include protein at breakfast to help you stay full longer.
❤️ Healthy Habits Are Better Together
This month, invite a spouse, friend or child to join you.
Meet at the gym-encourage one another to stay active.
Healthy habits are easier—and more enjoyable—when shared.
Don't strive for perfection. Consistency is what creates lasting health.
👨⚕️ Dr. Duffy's Take
"One of the questions I receive most often is, 'What's the best diet?' My answer is usually the same: the one you can maintain. Good health isn't built by one perfect meal or one intense workout—it comes from making small, healthy choices consistently. Focus on building routines you can sustain, and your body will thank you for years to come."

Hypertension: More Than Just a Number
Blood pressure is not simply a vital sign recorded at the beginning of our office visit. It is a hemodynamic variable that reflects the interaction of cardiac output, systemic vascular resistance, arterial compliance, circulating volume, autonomic tone, renal sodium handling, and neurohormonal signaling.
Chronically elevated blood pressure exposes the arterial system to repetitive mechanical stress. Over time, that stress promotes changes in the blood vessels, heart chamber enlargements, kidney blood vessel injury, and accelerated atherosclerosis/plaque formation.
The clinical consequences include heart attack, stroke, heart failure, chronic kidney disease, damaged eye nerves and cognitive impairment.
In the United States, approximately 48% of adults meet criteria for hypertension, and prevalence rises markedly with age. Recent national data estimate hypertension in roughly 23% of adults ages 18–39, 53% of those ages 40–59, and 72% of adults age 60 or older.
In a large individual-participant meta-analysis of randomized trials, every 5-mmHg reduction in systolic blood pressure was associated with an approximately 10% relative reductions in major CV events. This benefit was observed in people with and without established CV disease and across a broad range of starting blood pressures.
👨⚕️ Dr. Duffy’s Take
The most important lesson in hypertension is that the diagnosis is not based on one isolated number, and treatment is not simply about making that number lower. We first need to know whether the measurement is accurate, whether the elevation persists outside the office, what is driving it, and how much cardiovascular risk the patient carries. The goal is not to treat the cuff—it is to reduce the patient’s lifetime risk of stroke, heart failure, kidney disease, and premature death while preserving quality of life.
What Did SPRINT Teach Us?
The SPRINT trial enrolled more than 9,000 adults age 50 or older who were at increased cardiovascular risk but did not have diabetes or prior stroke. Participants were randomized to a systolic target below 120 mm Hg or below 140 mm Hg.
At one year, the achieved mean systolic pressures were approximately:
121.4 mm Hg in the intensive-treatment group
136.2 mm Hg in the standard-treatment group
Intensive treatment reduced major cardiovascular events and all-cause mortality. The trial was stopped early because of benefit. Treating blood pressure to goal saves lives.
Why Hypertension Damages Specific Organs
Heart
Chronic pressure overload increases left ventricular wall stress. The heart adapts through enlarging its wall thickness, which may initially preserve systolic function but eventually impairs its ability to relax in between contractions and fill, contributing to failure of the heart as a pump.
Brain
Hypertension promotes both large-vessel atherosclerotic stroke and small-vessel breakdown, leading to mini-strokes, brain bleeds and cognitive impairment.
Kidneys
Elevated pressure in the kidney blood vessels leads to scaring, breakdown of the filtering function of the kidney and leakage of protein into the urine. Kidney disease can then worsen hypertension through sodium retention and neurohormonal activation, creating a bidirectional cycle.
Retina
Hypertensive vascular injury to the retina/back of the eye results in nerve damage and blindness.
Arteries
Chronic hypertension accelerates breakdown of the lining of the blood vessels and allow cholesterol plaque formation, aneurysm development, and arterial tearing.
Lifestyle Therapy: Expected Blood-Pressure Effects
Lifestyle changes are not merely supportive. In selected patients, their combined effect can rival that of one antihypertensive medication.
Approximate systolic reductions we see:
Weight reduction ~1 mm Hg/ kg body weight lost (1kg=2.2lbs)
DASH-style eating pattern ~5–11 mm Hg
Reduced dietary sodium ~ 2–6 mm Hg
Regular aerobic exercise ~4–8 mm Hg
Resistance exercise ~2–4 mm Hg
Moderating excess alcohol ~3–4 mm Hg
📌 Clinical Takeaways
Hypertension is common and frequently asymptomatic.
Cardiovascular risk rises continuously as blood pressure rises.
Measurement technique can alter diagnosis and treatment.
A 5 mm Hg systolic reduction is associated with a 10% relative reduction in major cardiovascular events.
Lifestyle therapy has measurable physiologic effects and should be prescribed with the same specificity as medication.
Treatment intensity should reflect absolute cardiovascular risk, comorbidities, tolerability, and patient preference.
