Depending on its severity, untreated OCD can lead to negative physical, mental, occupational, social, and emotional consequences that may significantly impair daily functioning. For example, someone who has a strong fear of contamination may avoid going to work, engaging in healthy relationships, or even leaving the house due to their overwhelming anxiety about germs. Meanwhile, someone who compulsively washes their hands may end up with raw, bleeding, or cracked skin. Some people with OCD may attempt to self-medicate by abusing drugs or alcohol.
