Thanks. How long has these vomiting episodes been going on for? Just once at night or multiple times a day? When he has a vomiting episode, it he retching and having abdominal contractions, or is it just coming up with no warning?
Thanks for the information. What we have to determine is if he is actually vomiting or regurgitating. They are very different and have different causes. Vomiting usually involves retching, nausea and abdominal contractions. Regurgitation just comes out. There is no warning. Vomiting can have many causes - dietary indiscretion, food allergy, inflammatory bowel disease, gastrointestinal foreign body obstruction (partial blockages can still produce feces), other sources of gastrointestinal inflammation or infection, intestinal parasites, immune mediated diseases, kidney disease, liver disease, pancreatitis, adrenal gland disease, pneumonia......the list is endless. Regurgitation is usually an esophageal problem. It may be due to a stricture in the esophagus, megaesophagus (widening of esophagus with very little muscular tone), esophagitis (inflammation or ulceration), esophageal cancer or parasites that embed into the wall of the esophagus (not common). Megaesophagus is most commonly caused by a stricture, specifically a vessel that comes off the heart and doesn't close like it normally should during birth (persistent right aortic arch),l or a neuromuscular condition called mysthenia gravis. Sometimes regurgitation is the only sign. If deemed to be vomiting, x-rays should still be done. I may want to run a barium study to make sure everything flows through the intestinal tract normally. It may even be therapeutic and soothe the stomach. I would make sure a fecal exam was ran. I would also want to run a CPL for pancreatitis. If everything is normal or is indicated from the x-rays, an abdominal ultrasound may be needed. I would at least put on some metronidazole to ease intestinal inflammation, pepcid and Cerenia (potent anti-vomiting medication). If it is deemed to be regurgitation, x-rays of the chest to look at the esophagus may be needed. Barium mixed with food can be used to outline the esophagus better. They may want to run a test for myasthenia gravis. There are a few different ones. Endoscopy would probably be the last step in either case if a cause can't be found. Please let me know if you have any other questions. Hope this helps.
