Question

which is a symptom that is common in people with sickle cell disease?
mood disturbances
fragile bones
stooped posture
frequent infections

Explanation:

Sickle cell disease causes red blood cells to be misshapen (sickle - shaped). This affects the immune system. The spleen, which helps fight infections, can be damaged in sickle cell disease. A damaged spleen makes it harder for the body to fight off bacteria, leading to frequent infections. Mood disturbances are more related to mental health disorders. Fragile bones are a symptom of osteoporosis. Stooped posture can be due to conditions like kyphosis or poor muscle strength, not directly related to sickle cell disease.

Answer:

frequent infections
