A recent study conducted by researchers at Linköping University in Sweden reveals surprising health impacts on individuals who cease using snus, a nicotine-containing product. Contrary to expectations, participants experienced elevated blood pressure and weight gain after discontinuing its use. This research, published in the Harm Reduction Journal, provides new insights into physiological changes following snus cessation.

The findings suggest that healthcare providers should monitor patients' blood pressure and weight closely when advising them to quit snus. The study involved 33 participants and highlighted the need for further investigation into the long-term cardiovascular effects of quitting snus, particularly for those with pre-existing health conditions.

Surprising Blood Pressure Changes After Stopping Snus

Contrary to initial assumptions, the study found that stopping snus led to an unexpected rise in blood pressure rather than a decrease. Participants showed an average increase of 3.7 mm Hg in systolic blood pressure, which remained steady over several weeks. This outcome challenges previous beliefs about the immediate effects of nicotine cessation.

Researchers anticipated a reduction in blood pressure after participants stopped using snus, given nicotine's known ability to temporarily elevate blood pressure. However, the study revealed an opposite effect, with blood pressure levels rising significantly. Professor Fredrik Nyström explained that this phenomenon remains unexplained, as factors like weight gain did not sufficiently account for the observed changes. He emphasized the clinical significance of these findings, suggesting that healthcare professionals should reassess how they guide individuals through the process of quitting snus. The study underscores the importance of monitoring blood pressure post-cessation, especially in individuals with existing cardiovascular issues.

Weight Gain and Implications for Cardiovascular Health

In addition to changes in blood pressure, the study noted an average weight gain of 1.8 kilograms among participants who ceased snus use. While this increase was notable, it did not fully explain the significant rise in blood pressure. These findings highlight potential broader implications for cardiovascular health.

Beyond the unexpected rise in blood pressure, participants also experienced noticeable weight gain during the study period. Although the exact mechanisms behind this weight increase remain unclear, researchers speculate it may be linked to behavioral or metabolic changes associated with quitting snus. Despite the relatively modest weight gain, its contribution to overall cardiovascular risk cannot be overlooked. Professor Nyström pointed out that such changes could necessitate adjustments in medication for individuals managing blood pressure-related conditions. The study emphasizes the need for comprehensive follow-up care when advising people to stop using snus, considering both blood pressure and weight management. Furthermore, the absence of a relapse group in the study limits understanding of reversible effects, highlighting the necessity for future research to address these gaps. Overall, the findings underscore the complex interplay between snus cessation and cardiovascular health, warranting careful consideration by healthcare providers.
