Overview

Bulimia Nervosa
Bulimia nervosa is an eating disorder characterized by repeated episodes of binge eating followed by behaviors intended to prevent weight gain, such as self-induced vomiting or misuse of laxatives. People may feel a loss of control during binge episodes and experience intense concern about body weight or shape. The disorder can occur at any body size and may not be obvious to others. Repeated compensatory behaviors can cause serious physical complications, including electrolyte disturbances, dental damage, gastrointestinal problems, and heart-related abnormalities.
Ankylosing Spondylitis
Ankylosing spondylitis is a chronic inflammatory condition that mainly affects the spine and the joints connecting the spine and pelvis. It commonly causes lower back or hip pain and stiffness that may worsen after periods of rest and improve with movement. In some people, inflammation can also affect other joints, the eyes, skin, or digestive system.

Diagnosis

Bulimia Nervosa
Diagnosis of bulimia nervosa involves a detailed assessment of eating patterns, binge episodes, compensatory behaviors, body-image concerns, mental health, and physical health. Clinicians may use established diagnostic criteria together with interviews and questionnaires. Physical examination and laboratory tests can identify complications such as dehydration or electrolyte abnormalities. An electrocardiogram may be needed when purging or electrolyte disturbance creates a risk of heart rhythm problems. Assessment should also consider other eating disorders and medical conditions.
Ankylosing Spondylitis
Diagnosis of ankylosing spondylitis is based on symptoms, physical examination, medical history, and imaging. X-rays may show changes in the sacroiliac joints or spine, while MRI can detect inflammation earlier in the disease. Blood tests may include markers such as C-reactive protein and testing for HLA-B27. No single test confirms the condition in every person.

Prevention

Bulimia Nervosa
Bulimia nervosa cannot always be prevented, but early recognition of unhealthy eating patterns and body-image concerns may help reduce progression. Avoiding repeated restrictive dieting and promoting balanced eating habits can be helpful. Families, schools, and healthcare professionals can encourage healthy attitudes toward food, weight, and appearance. People showing recurrent binge eating, vomiting, laxative misuse, or intense fear of weight gain should receive professional assessment. Early treatment can reduce the risk of serious physical and psychological complications.
Ankylosing Spondylitis
Ankylosing spondylitis cannot currently be prevented because its exact cause is unknown and genetic factors play an important role. People with a strong family history or persistent inflammatory back symptoms should seek medical evaluation. Early diagnosis and appropriate management, including regular physical activity and exercises recommended by healthcare professionals, can help maintain mobility and posture.

Risk Factors

Bulimia Nervosa
Risk factors for bulimia nervosa include a history of dieting, strong concerns about body weight or shape, pressure related to appearance, family or personal vulnerability to eating disorders, and certain psychological or emotional difficulties. Adolescence and young adulthood are common periods for onset, although the disorder can occur at any age. Social pressures, stressful experiences, and environments that emphasize weight or appearance may contribute, but no single factor causes bulimia.
Ankylosing Spondylitis
Risk factors include a family history of ankylosing spondylitis and genetic susceptibility, particularly the HLA-B27 gene. Symptoms commonly begin before age 45. People with inflammatory bowel diseases such as Crohn disease or ulcerative colitis, or with psoriasis, may also have increased risk of developing ankylosing spondylitis.
