Chloe, a 20-year-old college student, presented with fatigue, cold hands and feet, shortness of breath, and a swollen tongue and pale gums. The case study initially diagnosed her with iron deficiency anemia, which would be confirmed through a complete blood count showing low hemoglobin and red blood cell levels. Additional tests like endoscopy or colonoscopy may be used to check for internal bleeding as a cause. Treatment would involve iron supplements to restore her iron levels, along with a diet high in iron-rich foods.
