What are the most common causes of nausea and lightheadedness?

Nausea and lightheadedness can be caused by a number of different things, not all of which are serious. Nausea and lightheadedness are common symptoms of an illness like the flu; They can also be caused by medical problems like thyroid disorders, low blood sugar, high blood pressure, or diabetes, to name a few. However, in many cases, these symptoms can have a simpler explanation, such as excess alcohol, eating food that may not have been properly prepared, or even motion sickness, such as what can occur after traveling by car, boat or plane.

The flu is one of the most common causes of nausea and lightheadedness, and will usually progress to a fever as well as body aches and pains. If these symptoms persist and are not explained by recent illness or lifestyle changes, it may be best to see a doctor to rule out something more serious. He or she will usually be able to run some tests and determine if your symptoms are a cause for concern. However, in most non-severe cases, nausea and lightheadedness can be treated by getting some rest, breathing deeply through your nose, and eating something light, such as cookies or drinking ginger ale. If the symptoms are caused by low blood sugar, eating a snack or drinking some juice may help.

Drinking too much alcohol is one of the most common causes of nausea and lightheadedness. It may occur immediately after drinking, or it may not occur until the next morning. It's a good idea to drink plenty of water to rehydrate after drinking too much. Too much caffeine can also cause similar sensations.

Food poisoning is a common source of nausea and lightheadedness, but it usually progresses to vomiting or diarrhea if the food is really bad. Extreme pain, from an injury such as a broken bone or blood loss, can also cause immediate nausea and dizziness. Also, some people find that prolonged or acute stress can make them feel nauseated or dizzy, and anxiety or panic attacks can also cause these symptoms.

Motion sickness is another of the most common causes of nausea and lightheadedness. Some people experience this on any form of transportation, while others will only feel sick on a ship or plane, for example. It may be helpful to take ginger pills or motion sickness medicine in advance to prevent motion sickness from occurring. Taking deep breaths and looking at a fixed point on the horizon is also helpful to prevent nausea from getting worse.
