Common Causes of Spikes & Why Regular Checks Matter
As we age, monitoring blood pressure becomes more important than ever. But did you know it’s not just salt or stress that can soar those numbers? From hidden sugar in your diet to loneliness or even a poor night’s sleep, many everyday factors can quietly push your blood pressure up.
At Promyse Home Care in Kitchener, we understand how vital it is for seniors to monitor their heart health – which is why we offer our Blood Pressure Clinics to help you stay on track. We introduce ourselves and discuss your health history. We check your blood pressure and discuss how you can measure it at home. We also discuss lifestyle options for maintaining a healthy blood pressure.
Based on our conversation, we discuss current life stressors and medications or medication dosage changes. You are given a log book to track ongoing blood pressure and educated on frequency/type (automatic machines vs manual testing).
Upcoming Blood Pressure Clinic
On March 28th, 2025, 10:15 AM – 12:30 PM, we partnered with Riverbend Place Seniors’ Community at 650 Coronation Blvd, Cambridge, ON N1R 7S6, to offer our Blood Pressure Clinic to the Cambridge community. Here you can check your blood pressure and discuss lifestyle options for maintaining a healthy blood pressure.

Blood Pressure Spikes
Understanding why your blood pressure might spike, the importance of regular checks, and how small changes can make a big difference can empower you to take control of your health. By knowing the culprits that can cause blood pressure spikes, you can make informed decisions and take proactive steps to manage your blood pressure, making you feel knowledgeable and in control.
Culprits Why Your Blood Pressure Spikes
Hypertension
Hypertension is another term for high blood pressure, which refers to the measure of the force of blood pumped by the heart against the resistance of blood flow in the arteries. When this pressure becomes excessively elevated, it can damage the arteries and lead to other health conditions like cardiovascular disease, stroke, and kidney failure.
Sugar (The Sneaky Saboteur)
That extra cookie or sugary drink might do more than affect your waistline—it can also cause blood pressure spikes. Studies show sugar, especially fructose, can stiffen blood vessels and strain your heart. Just one 24-ounce soft drink can cause a 12% higher risk of high blood pressure!
Loneliness (The Silent Stressor)
Feeling isolated? Loneliness triggers stress hormones like cortisol, which can raise blood pressure over time. Staying socially active isn’t just good for the soul—it’s good for your heart too!
Sleep Problems (The Midnight Culprit)
Poor sleep or sleep apnea disrupts the body’s ability to regulate stress hormones. If breathing is repeatedly interrupted while sleeping, the nervous system releases chemicals that raise blood pressure. Sleep clinics in the Kitchener area are covered under OHIP, and you can be tested for sleep apnea. The goal for sleeping is to aim for 7-8 hours of quality rest every night.

Pain (The Unseen Trigger)
Chronic pain—whether from arthritis, an old injury, or headaches—keeps your nervous system on high alert, pushing blood pressure up. Managing pain is key to heart health.
5. Nutrition (Beyond Just Salt)
Too much processed food, caffeine, or even missing key nutrients like potassium and magnesium can affect blood pressure. A balanced diet with whole foods helps keep numbers steady. Include fruits, vegetables, beans and leafy greens like spinach to provide potassium that keeps the right amount of fluid in your blood.
6. Dehydration (The Overlooked Factor)
Even mild dehydration thickens your blood, making your heart work harder. Seniors often don’t feel thirsty until dehydrated, so sip water throughout the day! Try placing water bottles in each room you visit as a reminder to drink more water. Add a little lemon or lime to the water to enhance the taste.
Why Regular Blood Pressure Checks Matter
High blood pressure is often referred to as the ‘silent killer‘ because it rarely shows symptoms until damage has occurred. Regular checks provide a sense of security, helping to catch problems early and prevent strokes, heart disease, and kidney damage. Although temporary ‘spikes’ aren’t necessarily a problem, numbers that remain high over time can cause severe damage. Regular checks can bring a sense of relief, knowing that potential issues are being monitored and managed.
At our Blood Pressure Clinic, we:
- Take accurate readings
- Review your health history to spot risk factors.
- Provide a logbook to track your numbers at home.
- Offer tips tailored to your lifestyle.

When Nerves Trick Your Heart
Ever notice your blood pressure jumps at the doctor’s office but is fine at home? You are experiencing “white coat syndrome” – anxiety temporarily spiking your numbers. While it’s not usually dangerous, it can mask accurate readings. That’s why we recommend:
- Checking blood pressure at home (we’ll show you how!)
- Relaxing with deep breaths before a reading
- Tracking trends over time, not just one high result
A Success Story: Meet Margaret
Margaret, a lively 78-year-old from Kitchener, came to our clinic worried about her erratic blood pressure. After reviewing her logbook, we noticed spikes on days she skipped her morning walk or had sugary snacks. Her numbers improved within weeks with minor tweaks—like swapping afternoon cookies for fruit and joining a local walking group!
“I never realized how much little things affected my heart,” she says. “Now I feel more in control.”
