Nicky spent 31 years working for the NHS. She has no anxiety about doctors, no fear of check-ups, no reason to dread a blood pressure cuff. And yet, for years, her blood pressure readings told a different story every time she sat in a clinic.

"I have no fear or anxiety around health professionals," she says. "I worked for the NHS for 31 years." Despite that, she has a condition called white coat hypertension, a well-documented phenomenon where blood pressure spikes the moment it's measured by a health professional, regardless of how calm the patient actually feels.

It's a frustrating paradox: the very act of checking your blood pressure can distort the number you're trying to check. For Nicky, a 60-year-old with an otherwise healthy lifestyle, it meant her readings at the doctor's office never quite matched her day-to-day reality.

Finding a way to see the real picture

"I read about Hilo in a newspaper article, and I thought, this is the thing for me, because it measures your blood pressure without you knowing."

That's the heart of it. Hilo takes readings throughout the day, in the background, without a cuff, without the clinical setting that can throw the numbers off. No white coat, no spike.

When Nicky started using the Hilo Band, the picture became clear: "The app very clearly showed that I did have elevated blood pressure."

When you've already done "all the right things"

Here's what makes Nicky's story land differently: she wasn't starting from scratch.

"All the lifestyle changes that you can take to lower your blood pressure, I'd kind of already done them. I have a good diet, I do lots of exercise." With the usual first-line advice already in place, her doctor made the call to start medication.

It's a good reminder that hypertension isn't always about doing more. Sometimes the lifestyle box is already ticked, and the next step is having better information to act on.

A surprising discovery: the "reverse dipper"

Because Hilo monitors blood pressure both day and night, it revealed something Nicky didn't expect.

"The Hilo takes your blood pressure throughout the day and also the night, and I was surprised to see that when I'm asleep, my blood pressure actually rises. I'm one of those people that's called a 'reverse dipper,' and it has an association with increased risk of stroke."

Normally, blood pressure is meant to "dip" at night while the body rests. For reverse dippers, it does the opposite: a pattern that's invisible with a single daytime reading at the doctor's office, but exactly the kind of thing continuous, round-the-clock monitoring is built to catch.

Turning data into a decision

Nicky didn't just note the pattern. She looked into it. "I read a couple of medical research studies which indicated that it does help if you take your medication in the evening."

She made the change. And Hilo showed her, in black and white, that it worked: "The Hilo app very clearly showed the blood pressure came down."

Her takeaway

"The Hilo has given me a really easy way to know my true blood pressure, and to take the steps that I needed to take to bring it down a little bit."

For someone who spent her career in the NHS and has no fear of clinical settings, Nicky's story isn't about anxiety around medicine. It's about accuracy. It's about the gap between what a single office reading can show and what your blood pressure is actually doing, day and night, in the real world. Hilo closed that gap for her, and gave her the confidence to make an evidence-based change to her own routine.

Individual results vary; always speak with your doctor before making changes to your medication or treatment plan.
