generalized abd pain
What is constipation?
- Decreased frequency of bowel movements or difficulty having a bowel movement for more than two weeks with associated distress the child.
Difficult to define by actual frequency of BMs alone because of factors such as?
passage of stool, consistency of stool, and volume of stool

Know the Bristol stool chart!
What should the physical exam be like to assess for constipation?

When is functional constipation most commonly seen?
between 6 months and 4 years of age
Functional constipation?
- > 2 weeks of < 2 bowel movement s per week with hard, large or small stools in the absence of:
structural, endocrine, or metabolic abnormalities.
Functional constipation?
- Normal meconium passage
- Onset during transition periods
- No overtly distended abdomen
- Normal growth
- Overflow soiling
- Improved with medical therapy
Encopresis
Encopresis
What is the treatment for encopresis?
- Diet: fiber and water!
- Fiber
- Whole grains, fruits, and vegetables
- Rule of Thumb: age in years + 5 = goal of number of grams of fiber needed each day.
- Water/fluid intake
- About 2 oz per gram of fiber
- Liquids add fluid to the colon and bulk to stools, making bowel movements softer and easier to pass
Rule of Thumb: age in years + 5 = goal of number of grams of fiber needed each day.
treatment for encopresis
Encopresis treatment?
- Clean out (2-3 days)
- Maintenance medication (6 months-2 years)
- Sitting on toilet regularly – reward system
- Diet
- Keys to success: adequate clean-out, consistent use of medications, regularly scheduled toileting and improved diet.
Encopresis
Treatment continued (Medications)?

- Miralax
- Lactulose
- Milk of magnesia

- Senna syrup, tablets
- Ex lax
- Dulcolax
- Enemas:
- Milk and Molasses
- Saline
- Soap suds
Hypertrophied Pyloric
Stenosis
What is it?
Caused from hypertrophy of the pylorus
muscle
- The lumen becomes obstructed by mucosa, resulting in a blockage of the lumen that extends from the stomach to the duodenum
Hypertrophied Pyloric Stenosis
- Unknown cause, associated with a failure of nitric oxide synthetase and decrease nitric oxide and an inability of the smooth muscle of the pylorus to relax
Hypertrophied Pyloric Stenosis
Leads to several metabolic abnormalities, including metabolic alkalosis, hypochloremia and hypokalemia
Hypertrophied Pyloric Stenosis
Hypertrophied Pyloric
Stenosis?
- Occurs between1.4 and 4 per 10000 live births
- More common in males than females

- Typical case is a first born male presenting with recurrent vomiting between 3-5 weeks of age
- Infant between 2-8 weeks
- Presents with nonbilious projectile vomiting
- Infant remains hungry after feedings
- Generally not febrile or ill appearing unless the onset of dehydration produces lethargy
