Scientists from the University of Glasgow have found that chronic pain in different parts of the body significantly increases the likelihood of elevated blood pressure in adults. The results of the study were published in the journal Hypertension.

The researchers reached this conclusion after analyzing health data from 200,000 participants in the United States who experienced chronic pain. Participants indicated the location of the pain, its duration, and its impact on daily activities. To be included in the study, chronic pain had to last for at least three months.

The results showed that localized chronic pain increased the risk of hypertension by 20%, while short-term pain increased it by 10%. Chronic abdominal pain was associated with a 43% higher likelihood of the condition, headaches with a 22% increase, neck and shoulder pain with a 19% increase, and hip and back pain with 17% and 16% increases respectively.

The study also accounted for additional risk factors, including inflammation and depression. Inflammation was assessed by levels of C-reactive protein in the blood, while depression was evaluated using questionnaire data on low mood, loss of interest, anxiety, or apathy. Despite the influence of these factors, the link between chronic pain and elevated blood pressure remained.

“When providing care for people with chronic pain, healthcare professionals should take into account the increased risk of hypertension, both directly and indirectly. Early recognition of pain can help ensure timely diagnosis and treatment of cardiovascular complications,” noted study co-author Professor Jill Pell, MD.
