What are the causes of persistent nausea?

Updated November 21, 2016

People of all ages can suffer from persistent nausea. This can often be difficult to diagnose, however, there are some conditions that can cause persistent nausea.


Stress and anxiety can often trigger persistent nausea. Stress is present in our everyday lives and can be defined as something that causes you emotional, physical or mental strain. Stress can also cause other symptoms such as bloating, gas, acid reflux, vomiting or diarrhoea. Help to keep stress at bay by exercising, getting plenty of sleep and eating a healthy diet.


Undergoing chemotherapy treatment can often result in persistent nausea. Anti-nausea drugs can be effective in helping to eliminate this uncomfortable feeling. These medicines may be given through an IV or a patch, if the patient is unable to keep food or medication down. Avoiding strong odours, eating small meals throughout the day, staying hydrated, and avoiding heavy or greasy foods will help to reduce nausea during chemotherapy.

Inflammatory Bowel Disease

Inflammatory bowel disease or IBD affects more than 1 million people in the United States alone. This disease can cause chronic inflammation of the intestinal tract and can cause symptoms such as persistent nausea, red eyes, joint pain and skin rashes. There are medications that are commonly used to bring IBD into remission. These medications include steriods or aminosalicylates.


The medical term for persistent nausea and vomiting in pregnant women is Hyperemesis Gravidarum. While it is common for most pregnant women to experience some stomach upset, only 1.5 to 2 per cent of all pregnant women will develop this more serious condition. The cause of this condition is unknown, but some factors include hormones, gastrointestinal changes, stress and diet. Women who have experienced nausea in past pregnancies, obese women or women carrying a female foetus are at an increased risk for developing this condition.


If you experience persistent nausea, it could be the result of a serious medical condition. Seek the treatment of a qualified physician if nausea is persistent, is the result of pregnancy or becomes worse.
