Constant nausea is a symptom that is described by a persistent feeling that you are going to vomit. It can occur for many reasons, like pregnancy, medication use or as a side-effect of chemotherapy.
Some health conditions can also cause constant nausea, like labyrinthitis, gastroesophageal reflux (GERD), anxiety, or a food intolerance. Treatment of this symptom depends on the underlying cause and any other associated symptoms, like headache, diarrhea, or abdominal pain.

Why do I feel nauseous all the time?
The most common causes of constant nausea are:
1. Pregnancy
Many hormonal changes occur during pregnancy, like increases of human chorionic gonadotropin (also known as hCG), estrogen and progesterone. These hormones stimulate changes in the body, including increased breast size, but they also cause adverse effects like an aversion to strong smells, dizziness and nausea.
Nausea caused by pregnancy mainly occurs between the 7th and 10th weeks, however it can last for longer. In some women, they may feel nausea right up to the end of their pregnancy.
How to stop it: To improve symptoms of nausea during pregnancy, it is important to avoid an empty stomach. You should not fast for extended periods of time, and you should opt for meals that are lighter and less fatty. Another tip is to avoid drinking any liquids in the first 2 hours after waking.

If nausea is constant and leads to frequent vomiting, you should see your doctor or obstetrician to prescribe antiemetic medications that are safe for pregnancy.
