I’ll tell you what I’ve learned, from being in this ‘world’ for eleven (11) years now:
1) It’s Structural: the Lower Esophageal Sphincter (LES) is immature; the valve, the sphincter between the top of the stomach and the bottom of the esophagus isn’t yet fully developed, so the stomach acid comes up (and goes down) as it pleases.
a) Spitting Up: if there’s no pain, you’ve got what ‘they’ call a Happy Spitter and a Laundry Problem. If there’s PAIN, well, this is the burn of the acid and your baby is spitting it up and out.
b) Silent Reflux: isn’t silent at all! This is when there isn’t any spit up; your baby is bringing the acid up and swallowing it back down. This is a DOUBLE BURN!
2) It’s Related to Diet: i.e. a reaction to one, or more, PROTEINS in whatever it is that your baby is ingesting (formula or breastfeeding).
a) Milk Soy Protein Intolerance, MSPI: The ‘main’ proteins that babies react to are milk and soy. About 60% of babies (I’ve also read 40%; regardless, it’s a high percentage, hovering around 50%), who react to milk protein also react to soy protein.
A reaction to milk protein is NOT lactose intolerance! Lactose is milk SUGAR, and babies are ‘designed’ to ingest it (the principal sugar in human milk is lactose). Reaction/reflux due to diet has to do with proteins, milk and otherwise. Milk Names
1) Some babies won’t need medicine! Their mother goes on a diet to make her milk void of the offending protein(s) and there is a vast improvement with baby’s reflux! Or, the baby is formula-fed and the parents find the right formula and there is a vast improvement with baby’s reflux!
2) Getting rid of the offending proteins helps, and a big difference is seen with baby’s comfort and pain. However, medicine is still needed…Milk Names
3) It’s Both Structural and Protein Related
