11 Hidden Causes of Nausea You Never Considered

4. Food Sensitivities: Beyond Allergies

Food sensitivities, distinct from food allergies, can be a subtle yet significant cause of nausea. Unlike allergies, which trigger an immediate immune response, sensitivities may cause delayed reactions that are harder to pinpoint. Common culprits include lactose, gluten, and certain food additives. These sensitivities can lead to gastrointestinal inflammation, resulting in symptoms such as nausea. Identifying food sensitivities often requires an elimination diet or specialized testing. Once identified, dietary modifications can lead to significant improvements in symptoms. This section emphasizes the need for a thorough dietary assessment in individuals with persistent nausea and highlights the potential benefits of personalized nutrition plans.
