Patients with concussions typically experience transient disturbances of consciousness after injury, such as coma, along with recent memory loss. Some also suffer from various degrees of headache, dizziness, nausea, vomiting, loss of appetite, insomnia, and other clinical symptoms. The diet for concussion patients should be light and easy to digest, avoiding spicy foods and other strong irritants, as well as avoiding alcohol, since alcohol can aggravate symptoms like headaches, dizziness, and insomnia. Therefore, patients with concussions should not drink alcohol.
