Eating Disorders Defined
Anorexia Nervosa: An emotional disorder characterized by an intense fear of becoming obese, lack of self-esteem, distorted body image which results in self-induced starvation.
Bulimia Nervosa: Recurrent episodes of binge eating in which a person feels unable to stop eating voluntarily followed by a variety of weight control methods such as self-induced vomiting, fasting, consuming diuretics, and purging with laxatives.
Eating Disorders Not Otherwise Specified (EDNOS):
Dysfunctional eating habits/poor nutrition/deficiencies
Eating Disorders• 20% DEATH RATE Anorexia• 90% Adolescent & Young Women/10%
Male & >middle class• 20% of ALL athletes/33+% of Female
Athletes/ 5-10% teens
• Anorexia- 1% and Bulimia- 1.5% of adolescent Females
• Eating Disorders Not Otherwise Specified (EDNOS) up to 50-60%... funky nutrition
Chapter 8 4
Anorexia Nervosa• obvious thin/emaciated/sick appearance
• 12-21 females/competitive/perfectionist personality
• distorted body image/fat & food phobic (control of food)
• vv poor self-esteem & self perception • strong denial/depressed/easily agitated/angry • socially avoidant/cold/unemotional/lack of feeling
• often tightly controlled by parents or a COACH
• 3X normal rate of amenorrhea (loss of menses)Chapter 8 5
Bulimia Nervosa • binge & purge (10X day) to deal w/ life's
stressors
• total lack of control w/ food.. food controls them
• constant concern w/ body image/shape/appearance
• insecure/unjustified self-guilt/continually seeking approval
• secretive around food/steal & horde food/excessive use of restroom
• often alcohol + drugs involved Chapter 8 7
What is the Unhappy Female Triad?
The unhappy female
triad is a combination
of three different
disorders that commonly
affect females & especially athletes:
osteoporosis, eating disorders,
and amenorrhea.
(wikipedia 2000)
Who’s At Risk? Adolescents and women training in sports in which low body
weight is emphasized for athletic activity or appearance are at greatest risk.
• Pressure to be thin (gymnastics, figure skating, diving & ballet)
• Stay within a weight class (rowing & martial arts)
• Keep body size and shape (distance runners & cross country skiing)
Female athletes who are pressured by their coaches to lose
weight. • 67% of all college gymnasts surveyed had been told by their
coach that they were too heavy. (Rosen and Hough 1988)
• 5 of 6 divers reported that their eating disorder started after a coach told them they were too heavy. (Martin 1994)
Collegiate Athletes
A 1989 NCAA survey indicated that 60% of all female college athletes use weight control pills before entering college.
1995 study by Martin found that 60% of NCAA Division 1 female volleyball, softball, and basketball athletes used weight loss products prior to participating in college sports.
Physical Warning Signs• Rapidly losing weight or body fat• Limiting food intake• Constantly weighing• Eating secretly• Consistently going to the restroom
after meals• Abusing laxatives: this impedes
performance and results in dehydration, malnourishment, and unhealthy weight loss.
Psychological Warning Signs
Vulnerable self-esteem
Distorted body image
Obsessed with food or body weight
Constant need for approval
Depression
Anxiety
Codependent
Enough Is EnoughEnergy Stores
Food provides cellular maintenance, warmth, immunity, growth, movement and reproduction.
Reducing dietary energy intake or increasing exercise energy outflows lowers energy availability so that the body's other processes cannot function properly.
Amenorrhea Defined Delayed menstruation in development or the absence
of repeated periods after menstruation begins.
Menstrual abnormality that may be caused by low caloric intake, strenuous training, low body fat, low weight, or an eating disorder.
Physiological BreakdownA reduction in the frequency of luteinizing hormone (LH) pulses form the pituitary gland is the direct cause of amenorrhea and subsequent ovarian suppression in physically active women.
Amenorrhea Facts The lack of energy which comes form food sources
contributes to menstrual disorders
Menstrual cycle is temporarily suppressed to conserve energy
Can lead to infertility problems
Loss of regular menstrual cycles often reduces the body's production of estrogen which leads to an increased risk of becoming osteoporotic
Regular exercise can offset bone loss because of menstrual disturbances
Osteoporosis Defined The loss of bone mineral density and inadequate formation of
bone, which can lead to increased bone fragility and risk of fracture.
Osteoporosis (Weak Bones)
Defined as a bone mineral density more than 2.5 standard deviations below the average with a reduction in bone mass with no alteration in the mineralization of bone tissue
Low energy reduces rate of bone formation by suppressing metabolic hormones such as estrogen (slows turnover of bone)
Osteoporosis (Weak Bones)
Poor eating habits decrease the intake of calcium, vitamins, and minerals that we
need to build and repair bone
Bone Mineral Density Amenorrhoeic patients: lower at the spine (-5%), hip (-6 %), and whole body (-3%)
Patients with disordered eating patterns: lower at the spine (-11%), hip (-5%), and
whole body (-5%)
Physical Signs of Developing the Triad
Physical signs• cold hands and feet• dry skin• hair loss• absent or irregular
menstrual periods• increased rate of
injury• delayed healing
time for injuries• Stress fractures
Emotional Signs of Developing the Triad
Emotional signs • mood changes • decreased ability to
concentrate• depression
Consequences of the Triad
Nutrient deficiencies and fluid/electrolyte imbalance lead to impaired growth and mental functioning,
increasing the risk of other injuries
Long-Term Consequences
• Loss of reproductive function• Irreversible bone loss• Decrease in estrogen levels
• Dehydration• Starvation• Premature death
Developing the TriadDieting to lose weight or fat for participation to
improve performance & appearance, binge eating induced vomiting, and excessive use of laxatives.
Adolescents should gain body mass during their teenage years, except when losing body fat under the supervision
Triad Treatment
Be aware of causes
Inform family for support
Medical assistance
Nutritional support
Psychological intervention
Specified TreatmentEating Disorders
Treatments will vary individually on the basis of psychology and
environment – Increase the nutritional status– Increase muscle strength – Decrease risk of injury– Increase training and sports
performance
Specified Treatment
Menstrual disturbances
• Regular medical assessments• Decrease intensity/duration of training
by 10%• Estrogen replacement with the
contraceptive pill • Hormone replacement therapy, as
provided for postmenopausal women, not be used for long periods
Specified Treatment
For bone weakness
• Estrogen receptor modulators and intranasal calcium
• Calcium intake: increase to 1500-2000 mg a day to be taken along with vitamin D
Preventative MeasuresEducation related to eating healthy & lifestyleKeep track of menstrual periods Foods containing protein, fat, and carbohydrate
are healthy choices for the athleteVisit a dietitian if you need suggestions No skipping mealsNever aim to lose lean body massAny effort to lose body fat should be guided by a
healthcare professional
Prevention from a Coaches Perspective
De-emphasize weight Eliminate group weigh-ins Treat athletes individually Use guidelines for appropriate weight loss (1-2
pounds/week) Use objective measures when determining weight
ranges Reduce competitive thinness Teach safe nutritional practices
Treatment Programs
• Intervention by someone close to the subject (friends, family, teachers) is needed
• Be non-threatening when you address them & have access to a professional care immediately available
• Expect denial & refusal… be persistent! • Pro Treatment
– easily treated if detected early
– readily treated if moderately advanced
– V hard to treat in advanced stages
Chapter 8 31
How to Approach a Friend with an ED• DO approach them-vvv serious problem-
young people die
• Focus on health and unhappiness- NOT weight or appearance
• No simple cure exists
