Persistent nausea, or chronic nausea, is a symptom that can be caused by a variety of factors. Nausea is a feeling of queasiness or discomfort in the stomach that often leads to vomiting or a decreased appetite. Here are some common causes of persistent nausea:
Gastrointestinal disorders: Gastrointestinal disorders such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and gastroesophageal reflux disease (GERD) can cause persistent nausea. These conditions can cause inflammation and irritation in the digestive system, leading to nausea and vomiting.
Medications: Certain medications such as antibiotics, chemotherapy drugs, and painkillers can cause persistent nausea as a side effect. Additionally, long-term use of certain medications can cause damage to the liver and kidneys, which can also lead to persistent nausea.
Pregnancy: Nausea and vomiting are common symptoms of early pregnancy, and may persist throughout the entire pregnancy.
Migraine headaches: Migraine headaches can cause persistent nausea, particularly if the headaches are severe or accompanied by visual disturbances.
Anxiety and depression: Chronic nausea can also be a symptom of anxiety and depression. The stress and anxiety associated with these conditions can cause a range of physical symptoms, including nausea.
Motion sickness: Motion sickness is a type of nausea that occurs when the brain receives conflicting signals from the eyes and inner ear. This can cause persistent nausea, particularly during travel.
Medical conditions: Certain medical conditions such as liver disease, kidney disease, and thyroid disorders can cause persistent nausea as a symptom.
Food intolerances: Food intolerances and allergies can cause persistent nausea, particularly if the offending food is consumed regularly.
Cancer: Persistent nausea can also be a symptom of cancer, particularly if the cancer is located in the digestive system.
In summary, persistent nausea can be caused by a variety of factors, ranging from gastrointestinal disorders to anxiety and depression. If you experience persistent nausea, it’s important to speak with your doctor to determine the underlying cause and develop a treatment plan. Your doctor may perform a physical exam, order tests, and recommend lifestyle changes or medications to help manage your symptoms.
