Key Points:

• Functional constipation is constipation not due to any other underlying conditions such as Hirschsprungs, spinal cord dysphraphism, or other disease. 
• Functional constipation is defined as having at least 1 month of symptoms in kids younger than 4 years old (or) symptoms at least once per week for at least 2 months in kids older than 4 years old who do not meet IBS criteria. Symptoms include 2 or fewer stools per week, at least 1 episode of incontinence per week after toilet training is established, a history of excessive stool retention/retentive posturing/excessive volitional stool retention, a history of hard or painful bowel movements, the presence of large fecal mass in rectum, or a history of large diameter stools that may obstruct the toilet
• Encopresis is liquid stool that goes around large stool balls and is indicative of constipation rather than diarrhea
• Polyethylene glycol (PEG, miralax), lactulose, and enemas are all good treatment options for constipation
