Chronic Pain Fuels Higher Risk of High Blood Pressure

New long-term research links chronic, widespread pain to a substantially greater chance of developing high blood pressure. The study points to depression and low-grade inflammation as partial pathways connecting persistent pain with elevated cardiovascular risk, underscoring the need to treat pain as more than a symptom.

Study links chronic pain to increased hypertension risk

A large population study published in the journal Hypertension analyzed more than 200,000 adults and found that people living with chronic pain—especially when pain affects multiple body sites—are more likely to develop high blood pressure over time. The risk rose with how widespread the pain was: those reporting pain across many regions of the body faced the highest increases in hypertension risk compared with people reporting no pain or short-term discomfort.

High blood pressure (hypertension) occurs when the force of blood against artery walls becomes too strong, increasing the chances of heart attack, stroke and other cardiovascular events. New guidelines adopted by major medical societies place stage 1 and stage 2 hypertension beginning at 130/80 mm Hg, a threshold that now applies to nearly half of U.S. adults. Given the prevalence of both chronic pain and hypertension, understanding the link between them has major public-health implications.

How researchers measured pain, depression and inflammation

The analysis used data from the UK Biobank, a large research resource that enrolled more than half a million adults aged 40–69 between 2006 and 2010. For this specific study, investigators examined 206,963 participants with an average age of 54 who were followed for roughly 13.5 years.

At baseline, participants completed a questionnaire about whether pain had interfered with daily activity during the past month and where the pain occurred—head, face, neck/shoulder, back, abdomen, hip, knee or across the whole body. People also indicated whether the pain had persisted for three months or longer, a common clinical threshold for classifying chronic musculoskeletal pain.

Depressive symptoms were screened using questions about mood, interest, restlessness and energy over the prior two weeks. Low-grade systemic inflammation was assessed by measuring C-reactive protein (CRP) in blood samples. Researchers then tracked incident high blood pressure using hospital records and diagnostic coding (ICD-10) to identify new hypertension diagnoses during follow-up.

Key results and what they mean

Across the follow-up period, nearly 10% of the study population developed high blood pressure. Compared with people without pain, those with chronic widespread pain faced substantially higher odds of a later hypertension diagnosis. In relative terms:

• Chronic widespread pain increased the risk of high blood pressure by roughly 75%.
• Short-term pain was associated with about a 10% higher risk.
• Chronic pain limited to a single site increased risk by around 20%.

The study also broke down risk by pain location. Chronic abdominal pain, chronic headaches and neck/shoulder pain were among the site-specific complaints tied to higher hypertension risk, while hip and back pain showed more modest associations. Together, measured depression and CRP-mediated inflammation explained roughly 11.7% of the relationship between chronic pain and subsequent high blood pressure—indicating both psychological and biological mechanisms are at play, but that much of the link remains unexplained by these factors alone.

Lead investigators observed that people with chronic pain were more likely to have other risk factors for hypertension: higher body mass index (BMI), larger waist circumference, less healthy lifestyle habits and more long-term health conditions. The researchers adjusted for smoking, alcohol, physical activity, sedentary time, sleep duration and fruit and vegetable intake in their analyses to isolate the independent contribution of pain.

Expert Insight

"This study shows a clear pattern: the more widespread the chronic pain, the greater the risk for developing high blood pressure," said Dr. Maya Thompson, a clinical epidemiologist specializing in pain and cardiometabolic health. "That connection appears to be partially mediated by mood and inflammation, but there are likely additional pathways—autonomic nervous system changes, stress hormone responses, and the downstream effects of long-term analgesic use—that deserve closer study."

Dr. Thompson added, "Clinicians should view persistent pain as a marker of cardiovascular risk. Screening for depressive symptoms and monitoring blood pressure over time in patients with chronic pain can help identify those who need earlier intervention."

Implications for patients, clinicians and future research

These findings carry several practical messages. First, better pain management may reduce not only suffering but also long-term cardiovascular risk. Interventions that combine physical therapy, psychological support (such as cognitive behavioral therapy), lifestyle changes and careful medication selection could have dual benefits. Second, routine mental health screening in people with persistent pain may help identify depression early—treatment of which could blunt a portion of the increased hypertension risk.

Medication choices matter. Nonsteroidal anti-inflammatory drugs (NSAIDs), including commonly used over-the-counter agents like ibuprofen, are known to raise blood pressure in some people and can interfere with antihypertensive therapies. The study authors and other hypertension experts recommend that clinicians consider the impacts of pain medicines on blood pressure when treating chronic pain, especially in patients already at cardiovascular risk.

From a research perspective, the observational design cannot prove causation. The cohort was predominantly middle-aged and older white adults from the UK, so findings may not generalize to younger populations or to diverse racial and ethnic groups. Self-reported pain at a single time point and reliance on ICD-10 coding for hypertension are additional limitations. Randomized controlled trials testing whether specific pain treatments reduce incident high blood pressure would be the next step to establish a causal pathway.

Conclusion

The relationship between chronic pain and high blood pressure highlights the interconnectedness of physical, psychological and cardiovascular health. Chronic pain—particularly when it is widespread—should prompt clinicians to consider more comprehensive risk assessment, including depression screening and blood pressure monitoring. For patients, addressing persistent pain proactively and discussing the cardiovascular side effects of pain medications with providers are practical steps toward reducing long-term risk.

Ultimately, pain management strategies that treat the whole person rather than a single symptom may offer the best opportunity to limit the cascade of health problems that can follow chronic pain, from poorer mood and inflammation to the increased likelihood of hypertension and cardiovascular disease.
