Loss of appetite after food poisoning

Vomiting and diarrhoea can irritate the digestive tract and leave you dehydrated. Nausea, cramps, bloating, and temporary food aversion may continue after the worst symptoms settle. Gastroenteritis describes inflammation of the stomach and intestines and can have infectious causes. Appetite should gradually become easier as fluids and digestion improve; symptoms that persist, recur, or worsen may need a different explanation, such as Gastritis or Peptic Ulcer.

Take frequent small sips of water or an oral rehydration solution, particularly after loose stools. When nausea eases, begin with small portions of simple foods and increase variety as tolerated. Avoid alcohol and foods that clearly worsen cramps or diarrhoea. Wash hands carefully and avoid preparing food for others while diarrhoea or vomiting continues. Do not use anti-diarrhoeal medicines for bloody diarrhoea or fever unless a clinician advises you.

Seek urgent care for severe or localised abdominal pain, repeated vomiting, blood or black material in vomit or stools, fainting, confusion, or inability to drink. Arrange prompt medical review for high fever, signs of dehydration such as very little urine, diarrhoea that is not settling, or appetite that remains markedly reduced. Children, older adults, pregnant people, and those with long-term conditions may need earlier advice.

Could this still be an infection, or is another digestive problem likely? Do I need testing or rehydration treatment? Which foods and medicines are suitable for me? How long should I monitor the symptoms before arranging review?
