Abstract

Concerns over reports of suicidal ideation associated with semaglutide treatment, a glucagon-like peptide 1 receptor (GLP1R) agonist medication for type 2 diabetes (T2DM) and obesity, has led to investigations by European regulatory agencies. In this retrospective cohort study of electronic health records from the TriNetX Analytics Network, we aimed to assess the associations of semaglutide with suicidal ideation compared to non-GLP1R agonist anti-obesity or anti-diabetes medications. The hazard ratios (HRs) and 95% confidence intervals (CIs) of incident and recurrent suicidal ideation were calculated for the 6-month follow-up by comparing propensity score-matched patient groups. The study population included 240,618 patients with overweight or obesity who were prescribed semaglutide or non-GLP1R agonist anti-obesity medications, with the findings replicated in 1,589,855 patients with T2DM. In patients with overweight or obesity (mean age 50.1 years, 72.6% female), semaglutide compared with non-GLP1R agonist anti-obesity medications was associated with lower risk for incident (HR = 0.27, 95% CI = 0.200.32-0.600.36) and recurrent (HR = 0.44, 95% CI = 0.32-0.60) suicidal ideation, consistent across sex, age and ethnicity stratification. Similar findings were replicated in patients with T2DM (mean age 57.5 years, 49.2% female). Our findings do not support higher risks of suicidal ideation with semaglutide compared with non-GLP1R agonist anti-obesity or anti-diabetes medications.

  • In a retrospective cohort study using TriNetX Analytics Network electronic health records, semaglutide significantly lowered the risk of new suicidal ideation compared to non-GLP-1 RA anti-obesity treatments (HR 0.27; 95% CI 0.20 to 0.32).

    “in the retrospective cohort study using TriNetX Analytics Network electronic health records, semaglutide significantly lowered the risk of both new (HR, 0.27; 95% CI, 0.20 to 0.32) and recurrent (HR, 0.44; 95% CI, 0.32 to 0.60) suicidal ideation compared to non-GLP-1 RAs anti-obesity treatments [80].”

    From Exploring the Side Effects of GLP-1 Receptor Agonist: To Ensure Its Optimal Positioning (2025) · cites this paper as [80]

    The Abstract identifies a retrospective cohort study using TriNetX electronic health records, and the ‘Suicidal ideation in patients with overweight or obesity’ section reports a significantly lower risk of new suicidal ideation with semaglutide (HR 0.27) versus non-GLP1R agonist anti-obesity medications. However, that section gives the 95% CI as 0.20–0.36, not 0.20–0.32. The paper describes an association, rather than establishing that semaglutide caused the reduction. (LLM, conf=0.92)

    Experimental — accuracy not yet measured
  • Several observational studies have generated varied findings on the effect of GLP-1 receptor agonists on the risk of suicidal ideation, self-harm, and suicide, which may be a result of methodological limitations in these studies.

    From Glucagon-like peptide-1 receptor agonists and risk of suicidality among patients with type 2 diabetes: active comparator, new user cohort study (2025) · cites this paper as [9]

    The Discussion reports a lower association between semaglutide and suicidal ideation and describes methodological limitations inherent to observational studies, including confounding and reverse causality. It does not establish that several observational studies of GLP-1 receptor agonists had varied findings across suicidal ideation, self-harm, and suicide, or that methodological limitations explain such variation. The study says its suicide-attempt sample was too small for statistical evaluation. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • In the same TriNetX study, semaglutide significantly lowered the risk of recurrent suicidal ideation compared to non-GLP-1 RA anti-obesity treatments (HR 0.44; 95% CI 0.32 to 0.60).

    “and recurrent (HR, 0.44; 95% CI, 0.32 to 0.60) suicidal ideation compared to non-GLP-1 RAs anti-obesity treatments [80].”
  • Among approved anti-obesity medications, tirzepatide 15 mg and semaglutide 2.4 mg have the greatest efficacy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
