So why does it happen? ANS dysregulation can disrupt healthy breathing patterns. As a result, carbon dioxide builds up in their lungs, increasing blood acidity which, incidentally, can also affect how your blood vessels constrict and dilate. Cerebral autoregulation is the process that controls the blood pressure in your head. And having too much or too little blood in your brain will cause problems. One of them could be nausea based on some research on acute mountain sickness. Your vestibular system, primarily located in the inner ear, is involved in balance.
It works along with your brain and your eyes to determine where your body exists in 3D space relative to everything around it. It also communicates with the brain and the ANS to dictate positional blood flow dynamics i. Sometimes, patients experience changes to the digestion process as a result of significant ANS dysregulation. One effect of this, which is linked to PCS headaches, is increased blood in the head and, consequently, decreased blood in the stomach and liver.
As a result, your meals might not move through your GI tract at the right speed, resulting in symptoms like constipation or diarrhea. Filtering of the blood by the liver could also be affected, leading to less detoxification and decreased production of chemicals that help digest food.
We also suspect that the influence of the ANS on the GI tract could result in new food sensitivities. There are still other issues that could influence your nausea. For example, some people ask if stress can make you nauseated. The answer is yes, under certain conditions. If your ANS is already dysregulated, stress can increase the severity of your resulting symptoms by aggravating it further.
Stress is often more of a contributing factor to an existing or underlying issue than a direct cause, however. Often, nausea is not an isolated symptom. Here are some of the most common combinations and what might be causing them. Note: Just keep in mind that this list is not a replacement for medical advice from visiting a health care provider with experience in concussion and post-concussion syndrome diagnosis.
An upset autonomic nervous system can result in gut inflammation, so you may experience nausea or other symptoms after eating certain foods especially if you are developing new food sensitivities. Try to include antioxidants in your diet to help calm things down a bit. These specific symptoms are often situation dependent.
Since these are all common symptoms of concussion and post-concussion syndrome, they could arise from any of the situations described in the previous section. All of these symptoms are difficult to deal with and can make you want to isolate yourself.
Concussion recovery time is weeks for many patients. Likewise, nausea that immediately follows a concussion known as acute concussion can last up to two weeks. Longer-lasting nausea should be a cause for concern. Patients suffering from post-concussion syndrome — that is, symptoms following a concussion that last for over three months — may experience nausea indefinitely, although it is most often associated with certain triggers rather than being present all the time. This is the only known method for demonstrating not only that an injury has occured, but which brain regions have been affected by the injury.
You can read more about how it differs from a structural MRI and why it works at this link. Diagnosis of post-concussion syndrome is often a complex process that can involve ruling out other medical conditions, evaluating symptom history, running imaging tests, and conducting an in-person physical and cognitive evaluation. The two we see most commonly are Dramamine tablets and Scopolamine patches. Nausea meds were never designed with long-term use in mind.
If the person cannot stop vomiting and cannot keep any food or liquids down, get them to the hospital immediately. Once your doctor has ruled out any serious conditions causing your nausea, there are some home remedies for nausea that you can try. These can help you reduce vomiting. Research has shown that taking deep, controlled breaths activates the parasympathetic nervous system.
This reduces the biological response that triggers vomiting and nausea. To practice deep breathing, simply close your eyes, and slowly inhale through your nose. Let the air completely fill your lungs, then hold for three seconds. Finally, exhale slowly through your mouth. Repeat several times until you feel the nausea subside. Many people find that acupressure helps reduce nausea and vomiting. Acupressure is based on the traditional Chinese medicine practice of acupuncture , which uses specific pressure points on the body to alleviate symptoms.
One effective pressure point for vomiting is located on your inner wrist. To find the pressure point, follow these steps:. Another pressure point that can help relieve nausea is the ear lobes.
Rub both ear lobes in a circular direction for two minutes or until the nausea subsides. This point also may reduce anxiety. Make sure you sip fluids slowly so as not to upset your stomach. To practice aromatherapy, try breathing an open essential oil bottle. You can also add the oil to a diffuser. One of the most effective essential oils to use for nausea is lavender since it offers many other benefits to brain injury patients.
Other oils you can use include:. If you need something stronger, there are also prescription anti-nausea medications your doctor may prescribe. Vomiting is a fairly common side effect of head injury. While isolated incidents of vomiting do not usually signal something serious, vomiting can be associated with skull fractures and hematomas. Therefore, the best course of action if someone is vomiting after a head injury is to have them seen by a physician.
Doctors may perform various scans to determine if a serious injury has occurred. Even if no serious brain damage is found, you can still experience nausea and vomiting for several days after a head injury.
