Does Semaglutide Cause Depression?

What Is Semaglutide?

Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist that mimics a natural hormone involved in regulating blood sugar and appetite. It is available under several FDA-approved brand names:

• Ozempic® – for type 2 diabetes
• Rybelsus® – oral version for type 2 diabetes
• Wegovy® – for chronic weight management in individuals with certain qualifying conditions

Note: Patients connected through Eden’s platform may discuss with a licensed provider whether semaglutide is appropriate for their individual health goals.

Does Semaglutide Cause Depression?

Current evidence does not confirm a direct causal relationship between semaglutide and depression. However, some studies have observed associations between GLP-1 receptor agonist use and psychiatric symptoms ¹.

A large cohort study found a significant association between GLP-1 RA treatment and an increased risk of psychiatric disorders, including depression and anxiety¹.
Conversely, other research suggests that GLP-1 medications may have antidepressant effects, potentially due to their anti-inflammatory properties ⁶.
These findings indicate a complex relationship between semaglutide use and mood changes, warranting further investigation.

What Might Contribute to Mood Changes?

Even though a direct link hasn't been proven, several factors may influence mood while using GLP-1 medications:

1. Brain Chemistry
   GLP-1 receptors are found in brain regions involved in mood regulation. Research suggests these drugs may influence neurotransmitter systems, but human data is still emerging ².
2. Appetite Changes
   GLP-1 drugs reduce appetite. For people who use food to cope emotionally, this may shift their mental well-being.
3. Physical Side Effects
   Nausea, fatigue, and other common side effects may indirectly influence mood, especially in patients with a history of depression.
4. Individual History
   Individuals with depression or anxiety may be more sensitive to psychiatric side effects. Clinical reviews suggest extra monitoring for these groups ⁴.

How Often Are These Symptoms Reported?

Mood-related symptoms in semaglutide users are relatively rare in clinical trials. However, post-marketing reports and case studies have observed mood changes ⁷

• A WHO database review linked semaglutide use to suicidal thoughts, especially among people also taking antidepressants ⁴.
• A case study in Frontiers in Psychiatry reported depressive symptoms developing shortly after starting semaglutide, which improved upon discontinuation ⁵.

Supporting Mental Health While Taking Semaglutide

Patients considering or currently using GLP-1 treatments should take proactive steps to support their mental well-being:

• Discuss any history of mental health concerns with your provider before starting treatment.
• Monitor emotional changes and report them to your licensed healthcare provider promptly.
• Maintain healthy routines: exercise, sleep, nutrition, and stress reduction.
• Never stop prescribed medication without licensed medical consultation.

Final Thoughts

There is no definitive evidence linking semaglutide to depression. However, individuals have reported mood changes, and emerging data suggests both potential risks and benefits. The relationship is complex and multifactorial. Patients should work closely with their licensed healthcare provider to monitor mental health during treatment.
