Hungry stomach bloating may be caused by gas in the stomach, or it may be caused by diseases, such as gastritis and pyloric obstruction. 1. Gas in the stomach: If you inhale too much air when you eat or talk, and the stomach moves slowly, the inhaled air cannot be discharged in time, so the phenomenon of bloating will occur when you are hungry. 2. Gastritis: If there is inflammation in the stomach, it will lead to delayed gastric emptying, and at the same time, the food will be over-fermented in the stomach, producing more gas, leading to a further increase in the pressure inside the stomach, so there will be the phenomenon of bloating when you are hungry. 3. Pyloric obstruction: some people have peptic ulcer, pancreatitis and gastric tuberculosis and other diseases, resulting in pyloric obstruction, which will make the gastric contents of the emptying slows down, so there will be symptoms of hunger bloating. It is recommended to go to the regular hospital to do the relevant examination, to clarify the specific causes, and actively comply with the doctor’s instructions to deal with, so as not to delay the condition.
