What Causes Dehydration In Newborns?

Dehydration in newborn can occur due to many reasons. The most common cause is infection in the gastrointestinal tract. Dehydration is not a disease in itself. It is a condition that can most often occur due to diarrhea, vomiting, fever and sweating. The child born to first time mothers may be more at risk because she may not be experienced in rearing and breastfeeding. However, it is not so in all the cases.

Infection probably occurs more commonly in bottle fed babies. It is mostly bacterial or viral intestinal infection. This may lead to diarrhea and vomiting. The baby may become severely dehydrated if there are frequent episodes of diarrhea and vomiting.

Dehydration can also occur if the mother is unable to breastfeed the baby or baby is unable to drink fluids due to oral disease such as thrush. The baby may refuse to drink milk because of soreness and pain in mouth. Intense heat can cause dehydration due to loss of fluid through sweating.

Signs And Symptoms Of Dehydration In Newborns

There are several symptoms that may indicate the baby has become dehydrated.

A normal newborn wets the diaper very frequently, but if the baby has not soiled the diaper since last 6 to 7 hours this is an indication of dehydration.
