In many cases, these changes cause a personâs organs to stop working. 1  Some of the signs that organs are affected include: 2  Heart â low blood pressure, fast pulse. 3  Lungs â low oxygen level, problems breathing. 4  Kidneys â making very little urine. 5  Brain â confusion, coma.
Indigestion and heartburn can cause excessive belching. Heartburn can stem from acid reflux, be the symptom of a peptic ulcer, or a sign that last night's spicy meal did not agree with your stomach lining.
But one of the more unusual, and less worrisome symptoms of anxiety is excessive belching. Belching can be caused by a variety of gastrointestinal issues, but anxiety is also one of the more forgotten causes. Anxiety - especially severe anxiety - can change the way you breathe and how you digest, both of which can lead to belching and burping.
