According to today's routine, it is very common to have the problem of gas formation in the stomach. Nowadays, even young children are facing gas problem. The biggest reason for this is the improper functioning of the digestive system, which is mostly seen in children. Apart from this, due to eating something upside down, more gas starts forming in the stomach. Gas builds up in the small intestine and occurs in a state of dyspepsia. Also, if you skip breakfast in the morning, it also creates gas. Due to this you may feel a burning sensation in the chest and pain in the stomach.
