- Skin pricking disorder (excoriation): This disorder was also recognized as a distinct diagnosis in the DSM-5. It is persistent pricking at your skin that results in lesions, infections, and clinically significant distress. It is prevalent in between 1 percent and 2 percent of the population.
- Hair-pulling disorder (trichotillomania): In this OCD-related disorder, you have a strong urge to pull the hair from your head, eyebrows, eyelashes, or elsewhere on your body. It is usually treated with habit-reversal training and cognitive-behavioral therapy.
- Body dysmorphic disorder: This disorder is a “preoccupation with one or more perceived defects or flaws in appearance that are not observable or appear slight to others.” The criteria include that you have performed repetitive behaviors of grooming or checking your appearance or have mental acts such as constantly comparing your appearance to others. Muscle dysmorphia is a subtype of body dysmorphic disorder in which you think your body is too small or not muscular enough.
- OCD and related disorders induced by a substance/medication or due to another medical condition: Exposure to certain substances and medications can induce the development of OCD symptoms. There also are certain medical and neurological conditions that can be associated with the development of the disorder.
In addition, although it is not uncommon for new mothers to experience a wide array of emotions following the arrival of a new child, the postpartum period has long been known to be a time of increased risk for the appearance, worsening, or recurrence of mood and anxiety disorders. A number of studies have suggested that the postpartum period may also present a risk for the onset or worsening of OCD.
