GLP 1 & Weight Loss

Does Wegovy Affect Your Mood or Cause Depression?

Wegovy can affect mood in some patients, with depression reported as a rare but possible side effect. Clinical trials showed mood-related side effects occurred in less than 2% of participants, though post-market reports suggest slightly higher rates. The medication works on GLP-1 receptors in both the gut and brain, potentially influencing neurotransmitter pathways that regulate mood. Some patients experience mood improvements due to weight loss success, while others may notice irritability, anxiety, or depressive symptoms.
