Each and every parent in this world prays for the good health of his or her kid, but some diseases like pyloric stenosis often increase their tension. It is a disease among the infants in which the child vomits with a lot of force and is sometimes accompanied by other problems like fluid imbalances, salt imbalances and dehydration. Gastrointestinal tract is the affected portion in this disease.

Pyloric stenosis is a problem in which the pylorus gets a narrower shape. Pylorus is the lower portion of our stomach. Stomach contents like food have to pass through the pylorus before entering the small intestine.

In pyloric stenosis, the muscles of the pylorus get thick and they obstruct the passage of the food into the small intestine. This disease has become fairly common among the infants these days. Male infants have a larger chance of suffering this disease. Chances of suffering from this disease increase by 20%, if the parents had ever shown the signs of this problem. It has also been founded that children with blood groups O and B are more prone to pyloric stenosis.

Infants who suffer from this are mostly 2 weeks to 2 months old and it has been seen that the disease shows symptoms after 3 months or so. It has become the most common disease among infants which is mostly treated by surgery.

The exact cause for the thickening of the pylorus is still not known as the doctors consider the involvement and combination of several factors which cause it. Different researchers have different views. Some say that maternal hormones are the main cause while other state allergy is the main cause that results in the swelling of the pylorus.
