How common is abdominal pain in gastroenteritis?

Gastroenteritis irritates the stomach and intestines. This can cause waves of cramps, a sore or unsettled feeling, bloating, and an urge to open the bowels. The discomfort may come and go around diarrhoea or vomiting. Pain alone does not identify the cause, because abdominal pain can arise from many digestive and non-digestive problems.

Take frequent small sips of fluid, especially if vomiting or loose stools make drinking difficult. Rest and choose food only when you feel able to eat; bland, simple meals may be easier to tolerate. Handwashing after using the toilet and before preparing food helps limit spread to others. A clinician can advise whether testing or medicines are appropriate when symptoms do not settle or you have relevant travel, food, or contact history.

Seek urgent assessment for severe or rapidly worsening pain, a hard or swollen abdomen, blood in vomit or stool, fainting, confusion, or inability to keep fluids down. Arrange medical advice for dehydration signs such as very little urine, marked thirst, or dizziness, and for symptoms that are not improving. Young children, older adults, pregnant people, and people with weakened immunity may need earlier advice.

Ask what features suggest a stomach infection rather than another cause of pain, whether a stool test is useful, and which warning signs should prompt urgent review. If medicines are considered, ask how they fit with your current prescriptions and medical conditions.
