Dizziness and nausea are symptoms that may develop for a variety of reasons. Among the most common causes of dizziness and nausea is blood pressure that is either too high or too low. An individual may also develop dizziness and nausea because he has become dehydrated. Pregnancy is among the most common causes of these symptoms as well. Sometimes dizziness and nausea may develop because of a serious undiagnosed medical condition. To rule out serious medical issues, a person may do well to notify his doctor when these symptoms arise.
One of the most common causes of dizziness and nausea is low blood pressure. Most people know that high blood pressure is a problem but are unaware that low blood pressure can be problematic as well. When a person’s blood pressure is too low, the affected individual’s brain may be deprived of the amount of blood it needs. As a result, a person may feel dizzy and experience nausea as well. In addition, a person who has low blood pressure may sweat, experience shortness of breath, vomit, and even have chest pain.
High blood pressure is also among the most common causes of nausea and dizziness. When a person has high blood pressure, his blood is forced against the walls of his arteries at too high a rate. This condition can cause nausea and dizziness as well as a range of other symptoms. For example, a person with high blood pressure might also have headaches and blurred vision. In some cases, chest pain and vomiting may develop as well.
Dehydration is one of the most common causes of dizziness and nausea. Dehydration occurs when a person is taking in less fluids than he is putting out in the form of human waste, sweat, and even breathing. Besides dizziness and nausea, a person may also experience a lack of tears, dry mouth, scant urination, muscle cramping, vomiting, and abnormal heart rhythms when he is suffering from dehydration.
