What is Feeling Sick (Nausea)?
Nausea, or feeling sick, is a common sensation with many possible causes, including infections, food poisoning, motion sickness, pregnancy, anxiety, or as a side effect of certain medications. It often resolves on its own or with simple self-care, depending on the underlying cause.
While usually not serious, persistent or severe nausea, or nausea alongside other concerning symptoms, is worth discussing with a doctor to identify the cause and appropriate treatment.
02 · Understand
Clinical context
Small, frequent measures often work better than trying to push through
When feeling nauseous, small sips of fluid and small amounts of bland food, rather than forcing a full meal or ignoring the sensation, tend to be better tolerated and support recovery.

Practical steps
Persistent Inability to Keep Fluids Down Needs Medical Attention
While mild nausea often settles with simple measures, being unable to keep any fluids down for an extended period needs medical assessment to prevent dehydration.
- 1Sip fluids slowly and in small amounts.This is often better tolerated than drinking large amounts at once.
- 2Eat small, bland meals if you feel able.Plain foods like crackers or toast are often easier to tolerate than rich or spicy food.
- 3Try ginger.Ginger tea or ginger biscuits are a well-known, gentle remedy for nausea.
- 4Get fresh air and avoid strong smells.These can sometimes worsen nausea.
- 5Rest in a comfortable position.Sitting upright rather than lying flat can sometimes ease nausea.
