GERD in children may cause repeated vomiting, effortless spitting up, coughing, and other respiratory problems, such as wheezing. Inconsolable crying, refusing food, crying for food and then pulling off the bottle or breast only to cry for it again, failure to gain adequate weight, bad breath, and burping are also common. Children may have one symptom or many; no single symptom is universal in all children with GERD. Of the estimated 4 million babies born in the US each year, up to 35% of them may have difficulties with reflux in the first few months of their lives, known as spitting up. About 90% of infants will outgrow their reflux by their first birthday. Mouth
Acid reflux into the mouth can cause breakdown of the enamel, especially on the inside surface of the teeth. A dry mouth, acid or burning sensation in the mouth, bad breath and redness of the palate may occur. Other not so common symptoms of GERD include difficulty in swallowing, water brash which is flooding of the mouth with saliva, chronic cough, hoarse voice, nausea and vomiting.Signs of enamel erosion are the appearance of a smooth, silky-glazed, sometimes dull, enamel surfaces with the absence of perikymata, together with intact enamel along the gum margin. It will be evident in people with restorations as tooth structure typically dissolves much faster than the restorative material, causing it to seem as if it “stands above” the surrounding tooth structure.
Medications
The primary medications used for GERD are proton-pump inhibitors, H2 receptor blockers and antacids with or without alginic acid. The use of acid suppression therapy is a common response to GERD symptoms and many people get more of this kind of treatment than their case merits. The overuse of acid suppression is a problem because of the side effects and costs. Proton-pump inhibitors
Proton-pump inhibitors (PPIs), such as omeprazole, are the most effective, followed by H2 receptor blockers, such as ranitidine. If a once-daily PPI is only partially effective they may be used twice a day. They should be taken one half to one hour before a meal. There is no significant difference between PPIs. When these medications are used long term, the lowest effective dose should be taken. They may also be taken only when symptoms occur in those with frequent problems. H2 receptor blockers lead to roughly a 40% improvement. Antacids
The evidence for antacids is weaker with a benefit of about 10% (NNT=13) while a combination of an antacid and alginic acid (such as Gaviscon) may improve symptoms by 60% (NNT=4). Metoclopramide (a prokinetic) is not recommended either alone or in combination with other treatments due to concerns around adverse effects. The benefit of the prokinetic mosapride is modest. Other agents
Sucralfate has similar effectiveness to H2 receptor blockers; however, sucralfate needs to be taken multiple times a day, thus limiting its use.
