Nausea

Causes of nausea

Nausea isn't an illness in itself but rather a symptom of an underlying condition. Nausea is the sensation of needing to vomit but may not necessarily lead to vomiting. Nausea is usually short-lived but persistent nausea is an indication of a physical or psychological problem.

Nausea can be caused pain, infection, disease, medications or movement (motion sickness). Poor nutrition, dehydration and electrolyte imbalance can cause nausea. For many pregnant women, nausea is a common symptom (referred to as morning sickness). People who suffer with psychiatric problems can feel nauseous and nausea can be induced by acute anxiety.

Symptoms of nausea

Alongside the feeling of needing to vomit, nausea can have accompanying symptoms such as:

• Sweating
• Feeling dizzy
• Dehydration
• Clammy skin
• Fever
• Confusion
• Lethargy

Diagnosis of nausea

In most cases, nausea usually passes and needs no medical intervention, however if your nausea is persistent then it could be an indication of a more serious underlying condition. You should visit your GP who will perform an initial assessment to determine the possible cause of your nausea. If further investigation is required, you may be referred for further diagnostic tests.
