What are the symptoms of gastroenteritis (stomach flu)?
Symptoms of gastroenteritis or stomach flu include abdominal cramps, stomach pain, nausea, vomiting, and diarrhea. You may also have fever, headache, and swollen lymph glands, depending on the type of bug that causes it. In severe cases of gastroenteritis, loss of bodily fluid can result in dehydration, a life-threatening condition that needs medical attention. Signs of dehydration include sunken eyes, light-headedness, increased thirst, dry or sticky mucous membranes in the mouth, lack of normal elasticity of the skin, decreased urine output, and decreased tears. You can avoid dehydration by continuing to drink fluids and gradually eating a bland diet such as the BRAT diet (bananas, rice, applesauce, and dry toast). A bland diet is easily digested and is unlikely to irritate your sensitive gastrointestinal system.
