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.
If you experience problems with gas, diet changes such as limiting foods known to cause gas and bloating (e.g., beans, cabbage, high-fat foods) or using digestive enzymes may be helpful. Ask your doctor or a dietician for help in reviewing your diet. Belching may be caused by swallowing too much air.
