The feeling of always being nauseous can have many possible causes. Common reasons include digestive issues such as gastroesophageal reflux disease (GERD), gastroparesis (delayed stomach emptying), peptic ulcers, and inflammatory bowel diseases like Crohn’s or irritable bowel syndrome (IBS). Other potential causes are infections, side effects from medications, anxiety or psychological conditions, motion sickness, migraines, and metabolic or chemical imbalances such as hypercalcemia or liver conditions like hepatitis. Hormonal changes including pregnancy or chronic illnesses can also be factors. Sometimes, nausea arises from central nervous system conditions or toxic substance exposure. If this nausea is persistent (lasting longer than a month) it is often termed chronic nausea and usually signals an underlying condition that needs diagnosis and treatment. It may be accompanied by symptoms such as vomiting, abdominal pain, fatigue, or changes in appetite or bowel habits, which can help narrow down the cause. Given the number of potential reasons for constant nausea, it is important to consult a healthcare professional for thorough evaluation when feeling nauseous constantly or over a long period, to identify and treat the underlying cause appropriately.
