Anorexia nervosa, frequently referred to as anorexia, is a disorder where people severely restrict the types and quantity of food they eat. Those with anorexia have an extreme fear of eating and gaining weight and may repeatedly weigh themselves or engage in harmful behaviors such as excessive exercise or starvation. Those with anorexia often find themselves preoccupied with food, but unable to consume a healthy amount of it. This results in symptoms such as abnormally low BMI, vitamin deficiency, fatigue, fainting, and amenorrhea (lack of menstruation in women). Anorexia may cause bluish discoloration of the hands, brittle and falling out hair, yellowish skin, and lanugo (fine, downy hair). Left untreated, anorexia can lead to organ failure, brain damage, and even death.

Bulimia nervosa, typically called bulimia, is a disorder where people binge (eat large quantities of food) and purge the food that they just consumed by vomiting, laxative abuse, fasting, or excessive exercise. This behavior is usually motivated by a feeling of powerlessness over eating and a fear of weight gain or desire for weight loss. Bulimia can occur in underweight, normal weight, and overweight people. Symptoms of bulimia include acid reflux, intestinal distress, dehydration from purging, amenorrhea, and dental erosion from vomiting. Some people with bulimia have swollen parotid glands (salivary glands near the cheeks) and red scars and marks on the backs of their knuckles. Electrolyte imbalance from bulimia can be particularly severe and may lead to heart attack or stroke.

Binge eating disorder (BED) is the most common eating disorder. People with BED feel that they are unable to control the amount of food they eat and may continue to binge after reaching a point of fullness. BED binges (consuming large amounts of food) are often accompanied by feelings of sadness, guilt, and shame. Symptoms of BED include obesity, acid reflux, weight gain, and dissatisfaction with one's body. People with BED tend to experience cycles of negative emotions and binges. Binges or BED episodes can be provoked by stress, boredom, restrictive dieting, depression, and other triggers.

Other common eating disorders include:

• Pica, eating things that are not food, such as paper, ice, or soil
• Avoidant/Restrictive Food Intake Disorder (ARFID), disinterest in eating and avoidance of food
• Other Specified Feeding or Eating Disorder (OSFED), abnormal eating that does not fall under any disorder

Many people with eating disorders do not consciously develop them, and have difficulty seeking treatment. For this reason, it's important to detect and treat eating disorders as early as possible. Treatment for eating disorders can vary from therapy visits to inpatient treatment, depending on the disorder and its severity. Treatment aims to not only restore physical health and correct negative behaviors, but to also promote psychological well-being and self-confidence.

OCD frequently revolves around themes such as the fear of contracting germs or the fear of death. Common obsessions include:

• Fear of getting contaminated by people or the environment
• Extreme concern with order or precision
• Fear of death or behaviors perceived as risky
• Fear of accidents, disasters, and traumatic incidents

These obsessions and compulsions often contribute to anxiety, depression, and recurring emotions of fear and disgust. People with OCD cannot "turn off" their patterns of thought or behavior, and thus must continually grapple with urges to behave or think in a certain way, as well as the emotions associated with these urges. Some OCD patients describe their entire life as revolving around their obsessions and compulsions and this can result in their missing out on important school and social activities, travel, and family time. The impact of OCD is extensive and can even make daily activities like drinking, reading, sleeping, and eating extremely difficult.

The obsessions manifest in compulsive behaviors that can have negative implications on one's life. Some examples of compulsive behaviors include, among others:

• Excessive hand washing or showering
• Constant reordering or arranging of items
• Refusal to fly, drive, or participate in other activities
• Refusal to leave one's residence

Obsessive-compulsive disorder affects adults, adolescents, and children. OCD has been observed in children as young as five or six years of age, usually through sensitivity issues, obsessions about dirt or germs, or repeated doubts. The cause of obsessive-compulsive disorder is unknown. However, a person's likelihood of developing the condition may be increased by a number of variables such as family history, stressful life events, and pre-existing mental health disorders.

OCD is diagnosed based on a patients' reported symptoms. For example, a pediatrician or child psychiatrist may ask children (or their parents) how often they wash their hands or experience behavioral urges. Psychiatrists will evaluate patients for other symptoms and may instruct patients to describe their mental processes, thought patterns, and previous traumatic experiences.

While there is no cure for OCD, treatment can greatly improve patients' functioning in daily routines and activities. A common treatment for OCD is cognitive behavioral therapy (CBT), which helps patients identify negative patterns of thought and behavior and learn how to adjust them. Aversion therapy may also help those who have a fear of germs or contamination by forcing them to confront their fear and slowly overcome it. Many patients also benefit from counseling to address the anxiety, stress, and trauma that may accompany OCD. Other treatments for OCD include oral medications such as selective serotonin reuptake inhibitors (SSRIs, which are antidepressants) to normalize levels of a brain chemical called serotonin, which may improve OCD symptoms. Medications such as fluoxetine (Prozac) and sertraline (Zoloft) can help alleviate OCD-related behavioral urges, anxiety, and depression. Many OCD patients also find OCD support groups helpful to learn new coping strategies, to socialize, and to verbalize their emotions and experiences.

It is important to note that while OCD is a common mental health disorder, it is not a personality trait. The term "OCD" is sometimes used to informally describe someone having a tendency towards organization or orderliness. This usage is pervasive but inappropriate - OCD is a severe, life-altering condition. Some people with OCD who successfully manage their symptoms find that they may benefit from other traits that may be associated with OCD, such as high attention to detail and precision.
