DS13 has, in the last few months, developed a problem with excessive burping - really, really frequent and voluminous burps, like he's got an infinite supply of air in there.
It happens after he eats, but also when he's hungry. He says there's a feeling of pressure when it happens, and he feels hungry even if he has just eaten. It seems worse after fatty or acidic food.
He was prescribed Lanzoprazole for two weeks and it improved things a bit. When he ran out, it got bad again, so he was prescribed a 6 week course and the GP referred him for an ultrasound. A fecal sample tested negative for H Pylori.
He had very severe reflux and was medicated till he was about 2. He continued to have problems, but not bad enough for medication, till he was about 9. But he has never had burping like this - it's like nothing I've ever seen! He was just trying to practice clarinet and had to stop because he was burping almost continuously.
Any idea what could be going on here? The GP said leaving him on the Lanzoprazole lone term isn't really an option, and it's not doing enough anyway - it's still negatively affecting his life.
