What common symptom is associated with hemophilia A in infants?

Easy bruising is a common symptom associated with hemophilia A in infants due to the deficiency of clotting factor VIII, which is crucial for normal blood coagulation. In individuals with hemophilia A, even minor injuries can lead to significant bleeding under the skin or from mucous membranes, resulting in easy bruising.

Infants may not be able to communicate or describe their symptoms, so caregivers and healthcare providers often notice unusual bruising that occurs without clear causes, such as falls or bumps during play. This can raise suspicion for hemophilia, especially in those with a family history of bleeding disorders.

While frequent nosebleeds can occur in some cases, they are not as universally indicative of hemophilia A as easy bruising. Similarly, symptoms like dry skin and loss of appetite do not directly relate to the bleeding tendencies associated with this condition and are less specific indicators of hemophilia.
