In a 22-day-old baby, gas, abdominal bloating, crying, and irritability can sometimes happen due to colic, swallowing air during feeding, improper burping, or mild digestive adjustment after birth. However, difficulty passing stool or urine along with abdominal swelling in such a small baby should not be ignored, because it may also indicate constipation, dehydration, feeding problems, infection, or occasionally a more serious intestinal or urinary problem. Newborn babies normally pass urine several times a day, so reduced urine output needs medical attention. Make sure the baby is feeding properly, burp the baby well after every feed, and avoid overfeeding. Gentle tummy massage and holding the baby upright for some time after feeding may help reduce gas. Some pediatricians may recommend anti-gas drops such as simethicone drops if needed, but medicines or drops should never be started without consulting a child specialist, especially in a newborn. Since your baby is only 22 days old and has abdominal swelling with difficulty passing stool and urine, it is safest to consult a pediatrician as soon as possible for proper examination. Seek urgent care immediately if the baby develops fever, vomiting, refusal to feed, persistent crying, severe abdominal swelling, reduced activity, or continues to pass very little urine.
