Patients with concussions typically present with transient disturbances in consciousness and recent memory loss following an injury. Some patients may also exhibit a range of clinical symptoms such as headaches, dizziness, nausea, vomiting, and loss of appetite. To alleviate vomiting in concussion patients, it is essential to maintain ample rest and a reasonable diet that is light and easy to digest. Avoid consuming highly stimulating foods and alcohol. Additionally, eat smaller meals more frequently. If vomiting is severe, symptomatic treatment can be administered. Currently, metoclopramide can be used for intramuscular injections as a standard treatment.
