How long food poisoning from pork lasts

Some foodborne illnesses cause abrupt vomiting, while others mainly cause diarrhoea and cramps that linger. Symptoms may start soon after eating or later, and the meal you suspect may not be responsible. Recovery should move gradually toward fewer bowel movements, less nausea, and easier drinking. Learn about [Food Poisoning](/conditions/food-poisoning/), [Nausea](/symptoms/nausea/), and [Vomiting](/symptoms/vomiting/).

Sip water or an oral rehydration solution regularly rather than drinking a large amount at once. Resume simple meals as appetite returns and rest between activities. Keep hands and bathroom surfaces clean, and do not share food while you have diarrhoea or vomiting. [Oral Rehydration Therapy](/treatments/acute-and-urgent-care/oral-rehydration-therapy/) is useful when fluid and salts have been lost.

Arrange medical advice when symptoms are not easing, return after improvement, or prevent normal drinking. Seek urgent help for severe abdominal pain, blood in stool or vomit, faintness, confusion, very little urine, or repeated vomiting. A persistent [Fever](/symptoms/fever/) or worsening [Diarrhoea](/symptoms/diarrhoea/) also deserves assessment. [IV Fluid Therapy](/treatments/acute-and-urgent-care/iv-fluid-therapy/) may be considered when dehydration cannot be corrected by drinking.

Ask what duration is expected for your symptoms, whether a stool test is appropriate, and when you can return to work or school. Mention recent travel, medicines, medical conditions, pregnancy, and the number of times you have vomited or passed stool.
