The feeling of constant nausea can be caused by a variety of underlying conditions. Some common causes include:
- Digestive issues such as gastroesophageal reflux disease (GERD), peptic ulcers, gastroparesis (delayed stomach emptying), inflammatory bowel disease (IBD), and irritable bowel syndrome (IBS).
- Infections or food poisoning that affect the stomach.
- Psychological conditions like anxiety or eating disorders such as bulimia.
- Medications or treatments, including cancer treatments like chemotherapy.
- Other causes like migraines, motion sickness, pregnancy (morning sickness), bowel obstructions, and certain neurological conditions.
If nausea lasts more than a month or is constant, it is often a symptom of an underlying chronic condition that requires medical evaluation to diagnose and treat properly. Seeking medical advice is important, especially if nausea is severe, persistent, or accompanied by other symptoms like severe pain, vomiting, or weight loss.
