One major study published in early 2025, which followed over 351,000 adults, found no statistically significant increase in the long-term risk of thyroid cancer for those taking GLP-1 medications compared to those on other diabetes drugs

Mechanisms hypothesised to underlie blood pressure reduction with tirzepatide include: Weight reduction : Loss of adipose tissue decreases sympathetic nervous system activity, reduces cardiac output, and improves insulin sensitivityall contributing to lower blood pressure Natriuresis : GLP-1 receptor activation may promote sodium excretion through renal effects, though direct evidence for tirzepatide is limited [10] Improved endothelial function : Weight loss and metabolic improvements may enhance vascular health Reduced inflammation : Adipose tissue reduction decreases pro-inflammatory cytokines that may contribute to hypertension It is important to note that whilst the blood pressure reductions are consistent across trials, tirzepatide is not licensed as an antihypertensive agent
This review takes that question head-on, with balanced framing and no buying recommendation, as of April 2026
However, those who quit the medications for six months saw a slightly higher risk, and those who stopped for two years had saw their risk rise 22%
After many sips (and deep breaths
