Anorexia may also cause bluish discoloration of the hands, brittle and falling out hair, yellowish skin, and lanugo (fine, downy hair). These physical symptoms are frequently accompanied by altered behaviors and emotions. Those with anorexia may feel compelled to hide their weight and actions from others. For example, someone with anorexia may wear oversized or baggy clothing to conceal weight loss or may deny hunger or lie about the amount of food that he or she consumes. Some people with anorexia may withdraw from social activities and may experience irritability and depression.

People of all ages, genders, and races may be diagnosed with anorexia; however, the condition affects more women than men. There is no single known cause for anorexia, but biological, psychological, and environmental factors may play a role. Athletes who participate in certain sports that emphasize body shape and size (such as ballet, figure skating, and wrestling) may be more likely to develop anorexia.

Anorexia has two subtypes that are referred to as the restrictive type and binge-purge type.

Restrictive type is the more frequently represented form of anorexia, involving the extreme restriction of food. Binge-purge type anorexia is food restriction accompanied by episodes of binging (eating large quantities of food) and purging (vomiting). Binge-purge type anorexia differs from bulimia as people with this type of anorexia severely limit calories and purge most of what they eat and are generally underweight, while those with bulimia are in a normal weight range. Left untreated, both types of anorexia have severe and life-threatening effects on health. Anorexia can lead to heart failure and even death.

Many people do not consciously develop anorexia, and have difficulty seeking treatment. For this reason, early detection and treatment helps with long-term recovery outcomes. Treatment for anorexia can vary from therapy visits to inpatient treatment, depending on the severity of a person's anorexia. Severe anorexia is typically treated in inpatient rehabilitation facilities, where patients increase their food consumption and gain weight under medical supervision. Eating disorder specialists provide therapy sessions and oversee a physical and mental treatment plan. Outpatient programs help patients return to a healthy weight through frequent talk therapy or cognitive behavioral therapy (CBT) sessions, specialized nutrition plans, and eating disorder support groups. Anorexia treatment aims to not only restore physical health and correct negative behaviors, but to also promote psychological well-being and self-confidence.

Other risk factors for BED include experience with dieting, mental health problems, and a family history of eating disorders. BED may progress and worsen over decades, increasing the chances of causing obesity, or related conditions such as diabetes and joint pain.

Treatment for BED aims to reduce binge frequency and to help patients gain healthy eating practices. Therapy, nutrition counseling, and eating disorder support groups help patients to recover from BED. For example, patients are frequently asked to share their binge patterns and feelings to develop a treatment strategy. Cognitive behavioral therapy (CBT) is a common BED treatment. This technique helps patients avoid negative thought patterns that trigger binges. Another treatment option is medication. For example, the FDA approved Vyvanse as an oral medication for BED. While typically used to treat attention deficit disorder (ADD), Vyvanse prevents binging by curbing impulses for some people with BED. People with BED are frequently prescribed antidepressant medication, which may accompany cognitive behavioral therapy. With proper treatment and support, many with BED are able to break free from the cycle of overeating and improve their eating habits.

Some people with bulimia may have swollen parotid glands (salivary glands near the cheeks) that give their face a puffy "chipmunk" appearance. Their skin may look dehydrated and dull from repeated purging. Red scars and marks on the backs of the knuckles are prevalent in those with bulimia. Eating disorder experts may refer to these as "Russel's sign," named after a well-known psychologist.

However, others with bulimia may not show any outward signs of having an eating disorder. They may deliberately hide their eating habits or conceal their purging after a meal. It is important that family members and friends help loved ones with bulimia seek treatment. While many people with bulimia are still able to lead outwardly successful and active lifestyles, bulimia may have lasting and severe consequences to one's health. Electrolyte imbalance from bulimia is particularly dangerous and may lead to heart attack or stroke. Similarly, continued dehydration and disturbances in electrolyte levels can cause kidney damage and reduced kidney function.

Treatment for bulimia typically includes therapy and nutrition counseling. Eating disorder support groups, both online and in person, are often beneficial to recovery. Medical professionals may also look to treat the mental health problems that frequently accompany bulimia, which are body dysmorphia, post-traumatic stress disorder (PTSD), and depression. Dietary specialists can assist patients with reintegrating foods into their diet and increasing consumed calories. Some patients may attend inpatient rehabilitation or eating disorder clinics, which provide all of the above treatments in a residential facility.

Fortunately, many people recover from bulimia and are able to fully restore their health.
