The most common symptom is vomiting after feeding. Your baby may also present with symptoms that suggest pain and discomfort such as crying and fussing, refusing milk feeds or when the spit up contains blood streaks.
First-line medications usually include an acid suppressant agent with the addition of a prokinetic agent. Surgery for fundoplication and insertion of gastrostomy feeding tube can be discussed with the paediatric surgeons, especially in cases whereby the child is neurologically-impaired, has persistent failure to thrive or recurrent aspiration etc.
If your baby is happy, feeding well and putting on weight well, there is no reason to worry and no need for medications. However, if the vomiting is associated with a lot of crying, fussing, arching, turning away (feed refusal) and decreased feeding (less than what is expected of a child of any given age or weight), this would be a cause for concern. If your child does not undergo treatment, he or she will refuse feeding and his or her weight gain will be affected.
