The Claim
Orlistat, phentermine/topiramate, and naltrexone/bupropion are associated with an increased risk of serious adverse events in adults with essential hypertension compared to placebo, with risk ratios of 1.45, 0.85, and 1.05 respectively, based on moderate-certainty evidence from randomized controlled trials involving over 10,000 participants; however, the evidence for all adverse events remains uncertain for orlistat and phentermine/topiramate.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults with essential hypertension, orlistat increases the risk of serious adverse events compared to placebo, phentermine/topiramate does not increase risk, and naltrexone/bupropion slightly increases risk, based on clinical trial data; however, data on all adverse events for orlistat and phentermine/topiramate is not conclusive.

These drugs increase nervous system activity that raises heart rate and tightens blood vessels, which forces the heart to work harder and can cause damage to organs like the heart, brain, or kidneys in people who already have high blood pressure.
What the research says
1 studyStudy: Long-term effects of weight-reducing drugs in people with hypertension.
The study found that orlistat and naltrexone/bupropion may increase serious side effects in people with high blood pressure, while phentermine/topiramate might not — but we’re not very sure about that one. The numbers in the claim match what the study found.
