The child may also have muscle aches and general malaise. Vomiting with fever may indicate a bacterial infection rather than a viral or parasitic infection. Other causes of vomiting can be acute infections outside of the gastrointestinal system such as upper respiratory tract infections and urinary tract infections. If your child is a diabetic, uncontrolled diabetes may lead to a condition called diabetic ketoacidosis which results in vomiting, among many other signs and symptoms. Some drugs may cause nausea and vomiting.
Food poisoning can also cause vomiting.
In infants, repeated projectile vomiting may indicate a bowel obstruction such as pyloric stenosis, which is narrowing of a part of the stomach. Bed rest is recommended with access to the toilet or bedpan if necessary. When the nausea is mild or has finished, feed the child some water, fruit juice or broth. Even if the child is vomiting, he or she should take small but frequent sips of these fluids. When the child can tolerate fluids without vomiting, bland foods such as cereal, jello, bananas and toast can be added to the diet gradually.
