Risk factorsBy Mayo Clinic staff
Risk factors for pyloric stenosis include:
- Sex. Pyloric stenosis occurs more often in males than in females.
- Family history. Studies found higher rates of this disorder among certain families and also among offspring of mothers who had pyloric stenosis.
- Early antibiotic use. Babies given certain antibiotics, such as erythromycin, in the first weeks of life for whooping cough (pertussis) have an increased risk of pyloric stenosis. In addition, babies born to mothers who were given certain antibiotics in late pregnancy also may have an increased risk of pyloric stenosis.
