Overview
Anorexia Nervosa
Anorexia nervosa is a serious eating disorder characterized by restriction of food intake, significantly low body weight, an intense fear of gaining weight, and a disturbed perception of body weight or shape. People with anorexia may severely limit food, exercise excessively, or use other behaviors to lose weight. The disorder can affect nutrition, bones, the heart, hormones, and other body systems, and it can occur in people of different ages and backgrounds.
Myositis
Myositis refers to inflammation of muscles involved in movement. It is a group of inflammatory muscle disorders rather than a single disease. Myositis may cause muscle weakness, fatigue, difficulty with activities such as walking or climbing stairs, and in some forms a characteristic skin rash. Polymyositis and dermatomyositis are examples of inflammatory myopathies. Some people can also develop difficulty swallowing or breathing when muscles involved in these functions are affected. Diagnosis and treatment depend on the particular type and underlying cause.

Autoimmune Disorder InfectionDiagnosis
Anorexia Nervosa
Diagnosis involves assessment of eating behavior, weight changes, thoughts about food and body image, and physical health. A healthcare professional may perform a physical examination and order tests to identify complications of inadequate nutrition or other causes of weight loss. Blood counts, electrolyte and kidney tests, liver and thyroid tests, protein measurements, urinalysis, electrocardiography, and bone-density testing may be used when appropriate. Psychological assessment also helps identify the characteristic eating and body-image concerns.
Myositis
Evaluation usually begins with a medical history and physical examination focused on muscle strength and the pattern of weakness. Blood tests may identify elevated muscle enzymes or evidence of autoimmune activity. Imaging can help assess affected muscles, and electromyography may provide additional information about muscle function. In selected cases, a muscle biopsy is performed to identify the type of inflammatory muscle disorder. The combination of clinical findings, laboratory testing, imaging, and sometimes biopsy helps establish the diagnosis.
Prevention
Anorexia Nervosa
There is no guaranteed way to prevent anorexia nervosa, but early recognition of unhealthy eating behaviors and excessive concern about weight may allow treatment before severe complications develop. Healthy attitudes toward food, body image, and physical activity can be encouraged in families, schools, and healthcare settings. Avoiding harmful dieting practices and discussing persistent concerns about weight, eating, or body image with a qualified professional can support early identification. People recovering from an eating disorder benefit from continued medical and psychological follow-up.
Myositis
There is no established way to prevent all forms of myositis because autoimmune and genetic factors can play an important role. Avoiding unnecessary exposure to known muscle-injuring medicines and promptly addressing infections or other medical conditions may reduce some risks, but prevention depends on the underlying cause. For people who already have myositis, appropriate treatment, physical therapy, safe exercise, adequate rest, and monitoring for swallowing or breathing problems can help reduce complications and preserve function.
Risk Factors
Anorexia Nervosa
Risk factors include a strong concern about body weight or shape, negative self-image, perfectionistic or highly rule-focused behavior, anxiety disorders, and certain social or cultural pressures related to appearance. Eating difficulties during childhood or adolescence may also be associated with increased risk. Anorexia commonly begins during the preteen or teenage years or young adulthood and is more frequently diagnosed in females, although it can affect males and people of all ages.
Myositis
Risk varies according to the type of myositis and its cause. Factors that may be relevant include autoimmune disease, certain infections, previous muscle injury, and exposure to medicines associated with muscle inflammation or injury. The specific age, sex, and pattern of risk also differ among inflammatory muscle disorders. A history of progressive weakness, difficulty rising or climbing stairs, repeated falls, swallowing problems, or breathing difficulty warrants medical evaluation rather than assuming the symptoms are due to ordinary muscle fatigue.
