Professional Assessment: Rapid weight loss in a 22-year-old female requires careful evaluation for several potential underlying causes, including thyroid disorders (particularly hyperthyroidism), eating disorders (given the age demographic, anorexia nervosa and bulimia are important considerations), malabsorption syndromes, and inflammatory bowel disease. The pathophysiological mechanisms could involve increased metabolic rate, reduced caloric intake, malabsorption of nutrients, or psychological factors affecting eating behaviors, with young adult females being at particularly higher risk for eating disorders and autoimmune thyroid conditions. Given the patient's age and gender, additional testing should include comprehensive metabolic panel, complete blood count, thyroid function tests (TSH, free T4), celiac disease screening, and psychological evaluation to rule out eating disorders. A detailed nutritional assessment, including food diary analysis and body composition measurements, would be essential for developing an appropriate weight gain strategy, while monitoring for any red flag symptoms such as persistent gastrointestinal issues or signs of malnutrition.

To regain weight healthily, increase your daily caloric intake by 500 calories above maintenance through nutrient-dense foods like nuts, avocados, lean proteins, and whole grains, combined with strength training exercises 3-4 times per week to build lean muscle mass. Incorporate frequent, smaller meals throughout the day and add healthy high-calorie smoothies made with protein powder, fruits, nut butters, and full-fat yogurt between main meals. Focus on getting adequate sleep (7-9 hours) and managing stress levels, as these factors can significantly impact weight gain efforts. For additional treatment recommendations, ask in the chat.
