Dhaka, Feb. 28 -- Stomach upset is a common phenomenon. It is a discomfort felt in the upper part of the abdomen. It encompasses a range of symptoms, including bloating or a feeling of fullness or tightness in the belly, usually due to the accumulation of too much gas. Patients often complain about abdominal pain and nausea. Vomiting is less common, and so is diarrhoea or constipation.

Stomach upset can be caused by viruses. The infection can lead to inflammation in the lining of our gastrointestinal tract, producing the characteristic features of the condition. It is usually not life-threatening. Simple home remedies can alleviate many symptoms; the upset stomach improves within a week. But on occasions, medical help is needed.
