Infants with diarrhea should be given fluids such as oral rehydration solutions or additional breast milk to prevent dehydration, explains WebMD. Caregivers can also give infants probiotics in consultation with a medical professional. Probiotics such as yogurt with live cultures replenish healthy gut bacteria.
Infants who contract diarrhea due to a dose of antibiotics or food poisoning are treated the same as infants with a viral infection that causes loose and watery stools, according to WebMD. Common symptoms of a viral infection in addition to diarrhea include fever, headache, stomachache and vomiting. Infants may also experience diarrhea
Diarrhea that is not treated with fluids can cause severe dehydration in infants, explains WebMD. Symptoms of dehydration include a lack of energy, cool or dry skin, very little urine that is dark yellow, dizziness, and a dry and sticky mouth.
Diarrhea in infants that is not caused by a viral infection, food poisoning or a reaction to antibiotics may be a symptom of a medical condition or noninfectious disease when it lasts for more than the typical four to five days, according to KidsHealth. Diarrhea could be an indicator that the infant has a food allergy, intolerance to lactose, or inflammatory bowel disease or a disease of the gastrointestinal tract.
