For many Filipinos diagnosed with high blood pressure, taking maintenance medicine becomes part of everyday life. Pills are taken every morning, doctor visits become routine, and many assume that as long as they never miss a dose, their condition is under control.
But health experts say that is not always the case.
Even with medication, some people continue to have dangerously high blood pressure without realizing it. Because hypertension often develops silently, many patients feel well even as the condition quietly damages the heart, brain and kidneys.
The challenge is significant in the Philippines, where an estimated 16.8 million people—roughly one in three adults—are living with hypertension. While medications have become more accessible over the years, doctors say controlling the disease requires more than simply taking prescribed drugs. Regular monitoring, follow-up consultations and periodic reassessment of treatment remain essential, particularly for patients whose blood pressure stays elevated despite treatment.
“Many patients assume that taking maintenance medication automatically means their blood pressure is under control, but that is not always the case,” Dr. Jhoanna Marcelo, a cardiologist at a leading specialty heart center in the Philippines, tells FrontpagePH.
“For some patients, blood pressure remains elevated despite treatment, increasing their risk of complications such as heart attack, stroke and kidney disease. Recognizing when hypertension is not responding as expected is important in helping patients receive the most appropriate care for their condition,” she added.
One condition that often goes unnoticed is resistant hypertension, a form of high blood pressure that remains uncontrolled despite the use of several medications at appropriate doses. Patients with resistant hypertension face a higher risk of life-threatening complications, including heart attack, stroke and kidney damage.
The condition can be especially difficult to detect because it usually causes no obvious symptoms. Without regular blood pressure checks and follow-up care, patients may not realize that their treatment is no longer enough until serious health problems develop.
Doctors say this highlights the importance of viewing hypertension as a condition that requires ongoing management rather than a one-time diagnosis. As patients age or develop other illnesses, treatment plans may need to be adjusted to keep blood pressure under control.
Medical advances are also expanding the options available to patients whose blood pressure remains difficult to manage. One of these is renal denervation (RDN), a minimally invasive procedure that targets overactive nerves connected to the kidneys, which play a role in regulating blood pressure.
While medication and healthy lifestyle changes remain the foundation of hypertension treatment, physicians may consider RDN for selected patients with resistant hypertension when conventional therapies fail to achieve adequate blood pressure control.
According to Marcelo, resistant hypertension can be particularly frustrating for patients who have spent years taking several maintenance medicines, especially when side effects make long-term treatment more difficult.
“The availability of RDN is encouraging because it expands the range of approaches available to physicians, allowing us to have more meaningful discussions with patients about their long-term treatment goals and management options,” she said.
Health experts emphasize that no single treatment works for everyone. What matters most is recognizing when blood pressure remains uncontrolled and seeking medical advice before complications occur.
For millions of Filipinos living with hypertension, the message is clear: taking medication is only one part of managing the disease. Equally important are regular blood pressure monitoring, follow-up consultations and open discussions with healthcare providers to determine whether current treatment is still working. Early action, doctors say, can make the difference between preventing complications and discovering them too late.
