There are several factors that can contribute to worsening symptoms of OCD. Stress, anxiety, or trauma can intensify OCD behaviours. Additionally, lack of sleep or disruptions in sleep patterns may also make symptoms worse. Certain life events such as major changes or transitions can exacerbate OCD. Untreated or poorly managed mental health conditions, like depression or anxiety disorders, can also impact the severity of OCD symptoms. It is important to seek professional help to effectively manage and cope with OCD if you are struggling.
