Family Dynamics

Families are seriously affected You may see in families: Enmeshment/blurred boundaries High Control May also tend to isolate from one another

Goals

The overall goal of treatment for the individual with anorexia nervosa is gradual weight restoration A target weight is usually chosen by the treatment team in collaboration with a dietitian. Target weight for discharge from treatment is usually 90% of average for age and height. Help the client to learn more effective ways of coping with the demands of life. The goal of nursing interventions with anxious clients with bulimia is to help them: Recognize events that create anxiety Avoid binge eating and purging in response to anxiety Verbalize acceptance of normal body weight without intense anxiety

Physical Symptoms Anorexia

Thin appearance Abnormal blood counts Fatigue Dizziness or fainting Brittle nails Hair that thins, breaks or falls out Soft, downy hair covering the body Menstrual irregularities or loss of Menstruation (amenorrhea) Constipation Dry skin Frequently being cold Irregular heart rhythms Low blood pressure Dehydration Bone loss LABS

More social risk factors

Transitions- Whether it's heading off to college, moving, landing a new job or a relationship breakup, change can bring emotional distress. One way to cope, especially in situations that may be out of someone's control, is to latch on to something that they can control, such as their eating patterns, which can eventually lead to an eating disorder if taken to an extreme. Sports, work and artistic activities-Athletes, actors and television personalities, dancers, and models are at higher risk of eating disorders. Eating disorders are particularly common among ballerinas, gymnasts, runners and wrestlers. Coaches and parents may unwittingly contribute to eating disorders by encouraging young athletes to lose weight. Media and society-The media, such as television and fashion magazines, frequently focus on body shape and size. Exposure to these images may lead some people to believe that thinness equates to success and popularity.

Eating Disorder Risk Factors

Gender. Teenage girls and young women Age- Although eating disorders can occur across a broad age range — from preadolescents to older adults — they are much more common during the teens and early 20s. Possible genetic predisposition -- Relatives of clients with eating disorders are 5 to 10 times more likely to develop an eating disorder. Family influences- People who feel less secure in their families, whose parents and siblings may be overly critical, or whose families tease them about their appearance are at higher risk of eating disorders. Emotional disorders- People with depression, anxiety disorders and obsessive-compulsive disorder are more likely to have an eating disorder. Dieting-People who lose weight are often reinforced by positive comments from others and by their changing appearance. This dieting may be taken too far and lead to an eating disorder.

Nursing Interventions

Help increase client understanding of body image distortion. Emphasize client capability to eat small portions without binging. Maintain clear boundaries. Avoid power struggles. Intervene in anxiety. Give positive feedback for adherence to plan. Engage in group therapy. Assist to identify issues (e.g., esteem, identity disturbance). Teach adaptive strategies. Collaborate with dietician to teach nutrition. Collaborate with interdisciplinary staff. Ensure that the client survives!
