Symptom 8: The Indirect Indication – Vomiting
Vomiting might appear as an unexpected symptom of shaken baby syndrome, seemingly unrelated to the violent action that the syndrome is associated with. However, this symptom is far from random. Repeated instances of vomiting without a clear cause, such as digestive disorders or infections, can signal underlying brain injury and should not be dismissed lightly.
The relationship between vomiting and SBS lies in the effect of traumatic brain injury. Forceful shaking can lead to an increase in intracranial pressure due to swelling or bleeding in the brain. This increased pressure can stimulate the area of the brain responsible for inducing vomiting, known as the area postrema.
Vomiting in the case of SBS often presents itself in a distinct manner. It tends to be forceful, occurring repeatedly and in larger quantities than regular spit-up. This symptom is not accompanied by other common causes of vomiting, such as feeding difficulties or stomach disorders. Instead, it seems to occur without a clear trigger, which is a distinguishing characteristic.
While vomiting can occur due to a variety of reasons in infants, unexplained and repeated bouts of vomiting should prompt further investigation. If this symptom is accompanied by other signs of SBS, such as changes in behavior or consciousness, it should be viewed with increased concern.
The onset of inexplicable, recurrent vomiting should serve as a cue to seek immediate medical attention. Although it may seem unconnected initially, when considered in conjunction with the full picture of SBS symptoms, it contributes to the puzzle that can lead to an accurate diagnosis of shaken baby syndrome.
