What should you know about organic failure to thrive?

Growth can be affected when a child cannot take in enough nutrition, has trouble swallowing, loses nutrients through the gut, or uses extra energy because of illness. Examples of contributing problems can involve the digestive system, heart, lungs, hormones, metabolism, or long-term infection. The term does not identify one diagnosis. It signals that a careful search for a physical cause may be needed alongside attention to feeding routines and family circumstances.

Arrange a child health review if growth, feeding, or energy levels concern you. The clinician may plot measurements over time, ask about pregnancy and birth history, review meals and drinks, and look for symptoms such as vomiting, loose stools, cough, breathlessness, pain, or fatigue. They may examine the child and arrange targeted tests or referral when the history suggests a medical condition. Keep a simple record of foods, drinks, symptoms, and feeding difficulties to support the visit.

Seek urgent assessment if a child is difficult to wake, has signs of dehydration, struggles to breathe, has blue or grey lips, persistent vomiting, blood in stool or vomit, severe pain, or cannot feed. Contact a clinician promptly when a child is losing weight, repeatedly refusing feeds, becoming much less active, or has a clear change in urine output. Do not force-feed a distressed child; explain what is happening to the treating team.

Ask which growth pattern is concerning, what possible medical causes fit the child’s symptoms, whether a dietitian or specialist review is useful, and how progress will be followed. Ask for feeding advice that matches the child’s age and any swallowing or digestive difficulties.
