Postpartum obsessive-compulsive disorder affects about 3-5% of women during pregnancy or up to a year after childbirth. Symptoms involve repetitive and intrusive unwanted thoughts and behaviors to avoid or relieve the thoughts. OCD is an anxiety disorder and can cause excessive worry and scary thoughts, which can be disturbing for someone experiencing it. A personal or family history of anxiety or OCD is a risk factor. However, postpartum OCD is treatable with talk therapy and medication. It is essential to understand the nature of obsessive thoughts and compulsions, practice self-compassion, and seek treatment early.
