Seeking medical advice

If you are vomiting and can't keep any food or drink down, you could become dehydrated or malnourished. Contact your GP or midwife immediately if you:

• have very dark-coloured urine or do not pass urine for more than eight hours
• are unable to keep food or fluids down for 24 hours
• feel severely weak, dizzy or faint when standing up
• have abdominal (tummy) pain
• have a high temperature of 38°C (100.4°F) or above
• vomit blood.

If you have any pain when passing urine or you pass any blood, you may have a urine infection and this will need treatment. Drink plenty of water to dilute your urine and reduce pain. You should contact your GP within 24 hours.

If you're worried about your symptoms, call NHS Direct on 0845 46 47 to speak to a medical adviser.
