Neonatal colic usually starts around 3 weeks after birth and disappears around 6 months.
Infantile colic usually starts around 3 weeks after birth, and is more common within 3 months. It is related to the imperfect development of the baby’s gastrointestinal function and the high excitability of the vagus nerve at night, so the symptoms are usually more obvious at night, which are mostly manifested as repeated crying, white lips, tense abdominal muscles, flexion of both lower limbs, and the baby’s irritability, which is usually relieved in less than 10 minutes, and the baby can fall asleep quietly.
Usually when the baby is about 6 months after birth, with the baby’s growth and development, colic can disappear.
When colic occurs in infants, reasonable feeding, abdominal warmth, or give abdominal hot compresses to relieve symptoms. However, frequent colic or with nausea, vomiting, bloody stools, etc. need to consult a doctor in time, under the guidance of the doctor to check the abdomen ultrasound to rule out intussusception and other surgical diseases, in order to timely treatment.
