Growth Failure
in Children
When a child isn't gaining weight or height as expected: what growth charts really tell us, the common causes, and how the right plan gets growth back on track.
Medically reviewed by Dr. Chitrakshi Tewari, MD (Paediatrics)
Growth failure, or faltering growth, means a child gains weight or height more slowly than expected for their age on standard growth charts. Causes range from feeding and nutrition to underlying medical conditions, so the trend across visits matters more than any single reading. Dr. Chitrakshi Tewari monitors growth online, helps find the cause, and works to get growth back on track.
Growth is a vital sign
A child's growth curve is one of the most sensitive indicators of overall health we have. WHO and UNICEF estimate that around 148 million children under five worldwide are stunted, and India carries a large share of that burden. The encouraging part: most growth failure in children is nutritional, identifiable, and very treatable when caught early.
Doctors don't judge growth from a single measurement. We plot weight and height on standard WHO or IAP growth charts and look at the trend. A child crossing down through centile lines is signalling something, even if today's number still looks "normal".
Signs worth a proper look
What to watch at each stage
Growth problems announce themselves differently as children get older:
- Slow regain of birth weight or persistently slow weight gain comes first; weight falters before height
- Feeding difficulties, reflux and recurrent illness are common contributors at this age
- Weight, length and head circumference should be plotted at every visit; the chart is the diagnosis
- Healthy children grow roughly 5–6 cm a year in this window; consistently less deserves a look
- Clothes and shoe sizes barely changing year to year is a practical red flag
- Compare against siblings and mid-parental height, not against the tallest child in class
- Delayed puberty plus slow height gain needs assessment, often with a bone-age X-ray
- ‘Late bloomers’ (constitutional delay) are common and often run in families, but that is a diagnosis to confirm, not assume
- Girls’ growth spurt comes early in puberty, boys’ comes late; timing changes what ‘normal’ looks like

What causes growth failure?
- Not enough energy in: the most common cause by far: feeding difficulties, inadequate complementary feeding after 6 months, excessive milk or juice replacing meals, and picky eating.
- Losses and malabsorption: coeliac disease, chronic diarrhoea, and worm infestation can quietly steal nutrition.
- Recurrent infection and chronic illness: repeated infections, asthma, kidney, heart or liver conditions raise energy needs.
- Hormonal causes: hypothyroidism and growth hormone deficiency slow height more than weight, a pattern doctors look for specifically.
- Normal variants: familial short stature and constitutional delay of growth and puberty are common, run in families, and often need reassurance rather than treatment.
How it's assessed and treated
Assessment starts with accurate measurement and plotting, a detailed feeding history, and an examination. Targeted tests, such as a blood count, coeliac screen, thyroid function and urine tests, are chosen based on the picture, with a bone age X-ray when height is the main concern. Treatment is matched to the cause: a calorie-dense feeding plan built around your family's everyday Indian foods, treating any underlying condition, correcting micronutrient gaps, and structured follow-up on the same chart so progress is visible.
Growth and the endocrine conditions behind it are a special interest of mine. I review your child's growth records and charts online, identify the likely cause, design a practical feeding plan, arrange the right tests locally, and track progress with you month by month. Growth monitoring is also built into every wellness plan.
Myths vs facts
Half of parenting a condition is un-learning what neighbours, forwards and well-meaning relatives insist on. Tap each card:
Many small children are perfectly healthy, but a child crossing down centile lines is not ‘just small’, they are growing more slowly than their own track. The chart, not reassurance, settles it.
Genetics sets the range, but nutrition, chronic illness, gut conditions like coeliac disease and hormone deficiencies decide whether a child reaches it, and those are findable and treatable, best caught early.
No tonic increases final height. Untargeted supplements mostly create expensive urine; the useful move is finding why growth slowed, then treating that cause.
Healthy growth is proportional and steady on the curve, not maximal weight. In fact, weight rising while height slows is a pattern that specifically suggests a hormonal cause worth checking.
