This happens in babies when the sphincter or valve-muscle overdevelops for reasons not very well understood, or in adults due to an ulcer or cancer scarring and closing the narrow passage out of the stomach. When no food or drink can pass the pylorus the person is starved and rapidly becomes dehydrated. The body's chemistry is also affected very quickly. Before surgery to open the passage can be done safely, the body must be intravenously fed and rehydrated to restore its health and ability to withstand surgery.
The cardiac sphincter or aka GE junction contracts at the distal end of the esophagus. So food enters into the stomach when the cardiac sphincter is relaxed.
What is the function of the cardiac sphincter?
The sphincter at the top of the stomach is called the cardiac sphincter because it is located near the heart, which is known as the cardiac region. This sphincter helps regulate the passage of food from the esophagus into the stomach, preventing backflow of stomach contents into the esophagus.
The lower esophageal sphincter is also known as the cardiac sphincter due to its proximity to the heart. It is a muscular valve that helps prevent stomach acid and contents from flowing back up into the esophagus.

What is the function of the cardiac sphincter?
The Cardiac sphincter prevents regurgitation of food from the stomach.
If the cardiac sphincter relaxes, it allows stomach contents to reflux back into the esophagus, causing acid reflux or heartburn. This can lead to symptoms like chest pain, regurgitation, and a sour taste in the mouth. Chronic relaxation of the cardiac sphincter can contribute to gastroesophageal reflux disease (GERD).

cardiac sphincter/lower esophageal sphincter (LES)
The cardiac sphincter and the pyloric sphincter.
It relaxes because of the hormone progesterone allowing food to come back to the esophagus.
The cardiac sphincter is the valve between the esophagus and the stomach.
