Hypovolemia is a low level of fluid in the body. Lower levels of blood make it hard to get nutrients and oxygen to the body. The heart, kidney, brain, and liver are at higher risk of harm. Treatment is needed right away.

Causes may be:
Dehydration due to:
- Problems absorbing fluids in the digestive tract
- Problems feeding
- Illness with vomiting or diarrhea
- Blood loss from an injury or illness
Hypovolemia is more common in infants who are sick and have fever, vomiting, and diarrhea. Other things that may raise the risk are:
- Bacterial infections
- Childhood illnesses, such as bronchiolitis
- Not taking in enough fluids
Problems may be:
- Nausea, vomiting, or diarrhea
- Few wet diapers
- Abnormal drowsiness
- Sunken eyes
You will be asked about your baby’s symptoms and health history. A physical exam will be done.
Your doctor may check your baby’s blood flow by putting pressure on a nail bed.
The cause of the hypervolemia will need to be treated. The goal of treatment is to replace fluids. This can be done with rehydration therapy.
