Nausea

Nausea is a symptom, not a diagnosis — and the cause matters.

Nausea is the unpleasant urge to vomit. It's triggered by dozens of things: infection, pregnancy, migraine, medication side effects, vertigo, anxiety, and more serious conditions like gallbladder or pancreas issues. Occasional, short-lived nausea is rarely dangerous; persistent or severe nausea needs a doctor.

When to worry

Seek urgent medical care for any of the following:

  • Vomiting blood or material that looks like coffee grounds
  • Severe abdominal pain or rigidity
  • Nausea with chest pain or sweating (possible cardiac)
  • Signs of dehydration — no urine for 8 hours, dizziness on standing
  • Confusion, severe headache, or stiff neck
  • Nausea lasting more than 48 hours

Safe self-care

Reasonable first steps while you wait for or decide on a consultation:

  • Sip clear fluids slowly — large volumes make it worse
  • Bland foods: toast, rice, bananas, plain yoghurt
  • Ginger tea or candied ginger often helps mild nausea
  • Avoid strong smells, fatty foods, and alcohol
  • Rest upright for 30 minutes after eating

Nausea — FAQ

Is nausea without vomiting a bad sign?

Not necessarily. Many common causes — early pregnancy, motion sickness, medication side effects — cause nausea without actual vomiting.

Can I take anti-nausea medication without prescription?

Some options are over-the-counter, but self-treating nausea for more than a day or two risks masking a serious cause. Speak to a doctor first.
