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.
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.

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.
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
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.
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
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.
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.
