There are several factors that could induce nausea and palpitations. Some of the most common causes would be anxiety, physical or mental stress or even a reaction to certain medications. Nausea and palpitations are typically symptoms of an underlying cause; therefore, doctors generally aim to diagnose the cause and not merely treat the symptoms.

Feeling nauseated and experiencing heart palpitations simultaneously could indicate a disorder known as a panic attack. When panic attacks occur, many individuals will experience a feeling of uncontrollable anxiety along with unexplained nausea and possibly an irregular heartbeat. Palpitations can be in the form of skipped heartbeats or simply a very fast heart rhythm.

Another common cause of nausea and palpitations could be a sign that the individual is not receiving adequate amounts of sodium in her diet or is not retaining sodium properly. In such a case, sodium or salt tablets may be prescribed to treat this condition. In conjunction with this, magnesium and potassium levels could also play a role. If the individual has low levels of magnesium or potassium, nausea and palpitations could possibly occur.

Low blood pressure has also been known to cause nausea and heart palpitations in some individuals. When there is a sudden drop in blood pressure, this could send the heart into an irregular rhythm. The disturbance in the heart's rhythm can cause the symptoms of nausea as a result.

Anemia can occasionally cause nausea and palpitations in more severe cases. Anemia is a deficiency in red blood cells and can cause the above symptoms as well as extreme fatigue. A physician can diagnose this problem by performing a simple blood test.

Some women who are experiencing menopause may occasionally suffer symptoms of nausea and palpitations. These symptoms can often be attributed to hormonal inconsistencies. Symptoms can typically be treated with medication. Hormonal replacement therapy is another treatment option as well.

Lyme disease, which is transmitted by the bite of an infected tick, can occasionally cause symptoms of nausea and palpitations. In many cases, this can be a very debilitating disease. Lyme disease often attacks other parts of the body, including the central nervous system, and is often a difficult disease to diagnose.

Thyroid disease can produce nausea and palpitations in certain individuals. Hyperthyroidism can mimic symptoms of a panic attack, which is why it is crucial for the patient to get a proper diagnosis. Treatment of thyroid disease includes medications and, occasionally, surgery. Nausea treatment can include prescription drugs or over-the-counter medications.
