When Is GP Consultation Recommended for Food Poisoning?

Food poisoning can cause vomiting, diarrhoea, stomach cramps, nausea and fever after contaminated food or drink. The main concern is fluid loss. A GP can assess how unwell you are, review medicines and medical conditions that may increase risk, and decide whether you need examination, testing or treatment. Blood in stool, worsening abdominal pain, repeated vomiting or difficulty keeping fluids down deserve medical advice rather than home monitoring alone.

Take frequent small sips of water or an oral rehydration drink. Rest, and eat light foods when you feel able. Avoid preparing food for other people while you have diarrhoea or vomiting, and wash your hands carefully with soap and water. Note when symptoms began, how often you are vomiting or passing loose stools, any fever or blood, recent meals, travel, and the fluids you have managed to keep down. This information helps the GP assess the illness.

Seek urgent medical help for confusion, fainting, very little or dark urine, severe weakness, severe or localised abdominal pain, bloody vomit or stool, breathing difficulty, or vomiting that prevents you from drinking. Babies, older adults, pregnant people, and anyone with a weakened immune system or a significant long-term illness may need earlier assessment. If symptoms are not settling or are getting worse, arrange a GP consultation promptly.

Ask whether your fluid intake is sufficient, whether any regular medicine should be adjusted while you are ill, and which symptoms should prompt urgent review. You can also ask when it is safe to return to work or prepare food, and whether anyone else who ate the same food should seek advice.
