After effects of stomach flu

A person should become better able to drink, eat and carry out normal activities. Continued fluid loss, worsening pain or a return of fever suggests the need for clinical advice rather than simply waiting longer.

Gastroenteritis irritates the stomach and bowel. Even when vomiting stops, the healing bowel may move food quickly or respond to meals with bloating and cramps. Reduced intake and fluid loss can explain headache, weakness or dizziness.

Some foods may be temporarily less comfortable, but broad food restriction is rarely helpful without individual advice. Watch the overall course: steadily improving stool frequency and appetite differ from symptoms that intensify, recur or include blood.

Drink small amounts often. An oral rehydration drink can replace salts as well as water when diarrhoea or vomiting has been substantial. Resume simple meals according to appetite, choosing smaller servings if a full plate worsens nausea.

Rest without remaining completely inactive once dizziness has settled. Careful handwashing with soap and water helps limit spread within the household. Clean frequently touched bathroom surfaces and avoid sharing towels, utensils or drinks while anyone is unwell.

Seek urgent care if fluids will not stay down, urine becomes very limited, there is fainting, confusion, severe weakness, blood or black material in stool or vomit, a swollen abdomen, or severe and persistent abdominal pain.

Contact a clinician if fever returns, diarrhoea is not easing, symptoms return after improvement, or eating and drinking remain difficult. Babies, older adults, pregnant people, and those with reduced immunity or significant kidney, heart or bowel conditions may need earlier assessment.

Ask whether dehydration needs checking, whether testing is useful, and how regular medicines should be managed if vomiting or diarrhoea affects absorption. Report recent travel, sick contacts, unusual meals, urine output, blood, fever and the sequence in which symptoms changed.
