Q40: Other congenital malformations of upper alimentary tract
The group of conditions referred to as 'Other congenital malformations of the upper alimentary tract' encompasses a range of disorders that are present at birth. These disorders affect the upper part of a person's digestive system, which includes the mouth, esophagus, and stomach. These malformations can occur due to a variety of reasons, such as genetic influences, maternal drug use, or complications during pregnancy. Common symptoms across this group include difficulty swallowing, vomiting, or failure to thrive in infancy. The progression of these conditions varies, some may cause immediate problems at birth while others may not become apparent until later in life. Affected systems primarily include the digestive system but may also impact other areas of the body, depending upon the type of malformation.
