In Gastrointestinal Syndrome, what is a common manifest illness symptom?

In Gastrointestinal Syndrome, nausea and vomiting are commonly recognized symptoms due to the impact of radiation exposure on the gastrointestinal tract. This syndrome is typically characterized by symptoms that arise from damage to the cells lining the stomach and intestines. The destruction of these rapidly dividing cells leads to a major disruption in the normal functions of the gastrointestinal system, which manifests as nausea and vomiting. Although loss of appetite may occur as a result of these symptoms, it is more accurately associated with the discomfort and distress caused by the gastrointestinal disturbances. Therefore, nausea and vomiting are more direct symptoms of Gastrointestinal Syndrome.

The other options, such as seizures and loss of balance, are related to neurological damage potentially caused by radiation but are not typical symptoms of gastrointestinal issues specifically.
