Understanding Chronic Nausea: Causes, Symptoms & When to See a Doctor

Consistent nausea, or the sensation that you are going to vomit, can disrupt your daily life and is a signal that something is wrong. There are a variety of possible causes of chronic nausea, and it requires a doctor's visit to determine the problem.

Medication

• Most prescription and over-the-counter medications can cause nausea as a side effect. If you're taking any drugs, talk to your doctor about alternatives or managing the nausea.

Infection

• Bacterial, viral or parasitic gastrointestinal infections commonly cause consistent nausea. Infections in other areas can have the same effect.

Alcohol

• Frequent consumption of alcoholic beverages can irritate your gastrointestinal tract and lead to chronic nausea.

Inflammation/Intestinal Blockage

• Disorders like Crohn's, pancreatitis and others that inflame your gastrointestinal organs can cause nausea and intestinal blockages, as can other obstructions like tumors and ulcers.

Central Nervous System Disorders

• Tumors, seizures, multiple sclerosis, migraines and other problems affecting your central nervous system often lead to continuing nausea.

Hormone Disorders

• Hormonal disorders from diabetes to thyroid or adrenal gland problems can present with a symptom of chronic nausea.
