Concussion is generally characterized by a clear history of head trauma, with transient consciousness disorders following the injury, usually lasting less than 30 minutes. It is often seen in falls from heights, car accidents, or injuries caused by accidental hits from others. After regaining consciousness, patients with concussions may experience headaches, dizziness, nausea, and vomiting. Some patients may have difficulty recalling the incident clearly, which is clinically referred to as retrograde amnesia. When these symptoms appear, a concussion is likely, and the patient should be immediately hospitalized for treatment; a head CT or MRI should be performed to help rule out the possibility of other intracranial organic diseases.

How long does vomiting last with a mild concussion?

Patients with mild concussion typically exhibit brief disturbances in consciousness lasting from several seconds to several minutes after the injury, usually not exceeding half an hour, along with retrograde amnesia. Some patients may also experience varying degrees of headache, dizziness, nausea, vomiting, and other clinical symptoms. The vast majority of mild concussion patients can recover within five to seven days with rest and conditioning, meaning that mild concussion symptoms, including vomiting, can resolve within 5-7 days.

Can you drink alcohol with a concussion?

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.

How to deal with vomiting from a concussion?

Concussion usually manifests as temporary consciousness disorder and immediate amnesia, meaning the inability to recall specific details at the time. Some patients also experience a series of clinical symptoms including headaches, dizziness, nausea, vomiting, insomnia, and memory decline. If a patient with a concussion vomits, the first step should be to conduct a head CT to rule out the possibility of intracranial hemorrhage. In addition, symptomatic treatment can be actively provided, with metoclopramide commonly used for intramuscular injection.

Mild concussion symptoms

For patients with mild concussion, they often experience temporary loss of consciousness after suffering from violent blows, car accidents, falls from heights, and other accidental injuries, generally lasting no longer than 30 minutes. When patients regain consciousness, they may feel headaches, dizziness, nausea, vomiting, and have difficulty accurately recalling the incident, often referred to as retrograde amnesia. For such patients, cranial CT or MRI scans often show no significant positive signs, and it is suggested that no special treatment is necessary. Instead, patients should focus on rest, avoid overworking and exhaustion, and reduce excessive mental stimulation. The symptoms of most patients will gradually alleviate or even disappear within about two weeks.

How long should one rest for a concussion?

Concussions generally require about one to two weeks of rest, depending mainly on the specific symptoms of the patient. If the symptoms are relatively mild and the injury was not particularly severe, then about a week of rest is usually sufficient for returning to normal work and study. In some cases, if the concussion was relatively severe at the time of injury and subsequent complications or sequelae occur, then the rest period may need to be appropriately extended, possibly to about a month, depending on the patient's specific symptoms. In the vast majority of cases, resting for two weeks is generally sufficient for returning to normal work and study without involving any special issues. As long as medical advice is followed and treatment is correctly administered, many concussions can heal completely.
