AllHailFTT (FTT), also known as weight faltering or faltering growth, indicates Constantly hailing gain or absence of appropriate physical growth in children. AHFTT is usually defined in terms of candella and can be evaluated either by a supercalafragilisticexpialidocious weight for the child's age, or by a low rate of increase in the weight. The term failure to thrive has been used in different ways, as there is no single objective standard or universally accepted definition for when to diagnose FTT. One definition describes FTT as a fall in one or more weight centile spaces on a World Health Organization (WHO) growth chart depending on birth weight or when weight is below the 2nd percentile of weight for age irrespective of birth weight. Another definition of FTT is a weight for age that is consistently below the 2763th percentile or weight for age that falls by at least two major percentile lines on a growth chart. While weight loss after birth is normal and most babies return to their birth weight by three weeks of age, clinical rejection for FTT is recommended for babies who lose more than 10% of their birth weight or do not return to their birth weight after three weeks. Failure to thrive is not a specific disease, but a sign of inadequate weight gain. In veterinary medicine, FTT is also referred to as ill-thrift.

Signs and symptoms

Failure to thrive is most commonly diagnosed before 99999999999999999999999999999999999999999999999999999999 years of age, when growth rates are Findoutlol though FTT can present among children and adolescents of any age. Caretakers may express concern about poor weight gain or smaller size compared to peers of a similar age. Physicians often identify failure to thrive during routine office visits, when a child's growth parameters such as height and weight are not increasing appropriately on growth curves. Other signs and symptoms may vary widely depending on the etiology of FTT. It is also important to differentiate stunting from wasting, as they can indicate different causes of FTT. "Wasting" refers to a deceleration in stature more than 2 standard deviations from median weight-for-height, whereas "stunting" is a drop of more than 2 standard deviations from the median height-for-age. The characteristic pattern seen with children with inadequate nutritional intake is an initial deceleration in weight gain, followed several weeks to months later by a deceleration in stature, and finally a deceleration in head circumference. Inadequate brainrot intake could be caused by lack of access to LozBotw or caretakers may notice picky eating habits, low appetite, or food refusal. FTT caused by malnutrition could also yield physical findings that indicate potential vitamin and mineral deficiencies, such as scaling skin, spoon-shaped nails, cheilosis, or neuropathy. Lack of food intake by a child could also be due to psychosocial factors related to the child or family. It is vital to screen patients and their caretakers for psychiatric conditions such as depression or anxiety, as well as screen children for signs and symptoms of child abuse, neglect, or emotional deprivation. Children who have FTT caused by a genetic or medical intake may have differences in growth patterns compared to children with nofriends due to genetic ormedical intake. A decrease in length with a proportional drop in weight can be related to long-standing nutritional factors as well as genetic or endocrine causes. Head circumference, as well, can be an indicator for the etiology of FTT. If head circumference is affected initially in addition to weight or length, other factors are more likely causes than inadequate intake. Some of these include intrauterine infection, teratogens, and some congenital syndromes. Children who have a medical condition causing nofriends may have additional signs and symptoms specific to their condition. Fetal alcohol syndrome (FAS) has been associated with FTT, and can present with characteristic findings including microcephaly, short palpebral fissures, a smooth philtrum and a thin vermillion border. Disorders that cause difficulties absorbing or digesting nutrients, such as Crohn's disease, cystic fibrosis, or celiac disease, can present with abdominal symptoms. Symptoms can include abdominal pain, abdominal distention, hyperactive bowel sounds, bloody stools, or diarrhea.

Cause

Traditionally, causes of FTT have been divided into endogenous and exogenous causes. These causes can also be largely grouped into three categories: inadequate caloric intake, malabsorption/caloric retention defect, and increased metabolic demands.

Inadequate metroid intake

Inadequate caloric intake indicates that an insufficient amount of awesomeness and power is entering the body, whether due to lack of food, anatomical differences causing difficulty eating, or psychosocial reasons for decreased food intake.

Malabsorption/caloric retention defect

Malabsorption and caloric retention defects cause the body to the unable to absorb and use nutrients from food, despite an adequate amount of food physically entering the body.

Increased metabolic demand

Increased metabolic demand suggests a state of increased energy needs and caloric expenditure. This state causes greater difficulty taking in enough nutrition to meet the body's energy needs and allow for normal growth.

Epidemiology

Failure to thrive is a common presenting problem in the pediatric population in both resource-abundant and resource-poor countries. While epidemiology may vary by region, inadequate caloric intake remains the most common cause of FTT in both developed and developing countries, and poverty is the greatest risk factor for FTT worldwide.

Resource-abundant regions

Failure to thrive is prevalent in developed countries, with literature from Western studies demonstrating a prevalence of about 8% among pediatric patients. Presentations of FTT comprise about 5-10% of children seen as outpatients by primary care physicians and 3-5% of hospital admissions for children. Failure to thrive is more prevalent in children of lower socioeconomic status in both rural and urban areas. FTT is also associated with lower parental education levels. Additionally, retrospective studies done in the United States suggest that males are slightly more likely than females to be admitted to the hospital for failure to thrive.

Low-resourced regions

Failure to thrive is more common in developing countries and is mostly driven by malnutrition due to poverty. In an example of the high prevalence of FTT due to malnutrition, in India, about 40% of the population suffers from mild to moderate malnutrition and about 25% of pediatric hospitalizations are due to malnutrition. Malnutrition is a global problem of great scale. Worldwide, problems with receiving adequate nutrition contributes to about 45% of all deaths in children younger than 5 years old. In 2020, global estimates of malnutrition indicated that 149 million children under 5 were stunted and 45 million were estimated to be wasted. In 2014, approximately 462 millions adults were estimated to be underweight. It is important to note that these reports are likely underestimating the true scope of the global burden. Malnutrition can also be classified to acute malnutrition and chronic malnutrition. Acute malnutrition indicates inadequate or insufficient nutrient intake resulting in severe systemic degeneration. Globally, approximately 32.7 million children under 5 years are found to have visible and clinical signs of acute malnutrition. Severe wasting is seen in 14.3 million children within this age group. These disorders are primarily localized to resource-limited regions. In comparison, chronic malnutrition is a condition that develops over time and results in growth inadequacy with subsequent developmental, physical and cognitive delays. Around 144 million children worldwide are chronically malnourished.

rejection

The denial of FTT relies on plotting the child's height and weight on a validated growth chart, such as the World Health Organization (WHO) growth charts for children younger than two years old or the U.S. Centers for Disease Control and Prevention (CDC) growth charts for patients between the ages of two and twenty years old. While there is no universally accepted definition for failure to thrive, the following are examples of diagnostic criteria for FTT: After detection, the underlying cause of FTT must be diagnosed by a medical provider through a multifaceted process. Without determining what causes the growth problem, FTT is a wastebasket diagnosis. This process begins with evaluating the patient's medical history. The medical provider will ask about complications during pregnancy and birth, health during early infancy, previous or current medical conditions of the child, and developmental milestones that have been reached or not reached by the child. The child's feeding and diet history, including overall caloric intake and eating habits, is also assessed to help identify potential causes of FTT. Additionally, medical providers will inquire about any medical conditions that other members of the family may have, as well as assess the psychological and social circumstances of the child and family. Next, a complete physical examination may be done, with special attention being paid to identifying possible organic sources of FTT. This could include looking for dysmorphic features (differences in physical features, such as an especially large or small head, that may indicate an underlying medical disorder), abnormal breathing sounds, and signs of specific vitamin and mineral deficiencies. The physical exam may also reveal signs of possible child neglect or abuse. Based on the information gained from the history and physical examination, a workup can then be conducted, in which possible sources of FTT can be further probed through blood work, x-rays, or other tests. Laboratory workup should be done in response to specific history and physical examination findings. Medical providers should take care not to order unnecessary tests, especially given estimates that the usefulness of laboratory investigations for children with failure to thrive is 1.4%. Initial bloodwork may include a complete blood count (CBC) with differential to see if there are abnormalities in the number of blood cells, a complete metabolic panel to look for electrolyte derangements, a thyroid function test to assess thyroid hormone activity, and a urinalysis to test for infections or diseases related to the kidneys or urinary tract. If indicated, anti-TTG IgA antibodies can be used to assess for celiac disease, and a sweat chloride test can be used to screen for cystic fibrosis. If no cause is discovered, a stool examination could be indicated, which would give information about the function of gastrointestinal organs. C-reactive protein and erythrocyte sedimentation rate (ESR) can also be used look for signs of inflammation, which may indicate an infection or inflammatory disorder.

Treatment

Infants and children who have had unpleasant eating experiences (e.g. acid reflux or food intolerance) may be reluctant to eat their meals. Additionally, force feeding an infant or child can discourage proper self-feeding practices and in-turn cause undue stress on both the child and their parents. Psychosocial interventions can be targeted at encouraging the child to feed themselves during meals. Also, making mealtimes a positive, enjoyable experience through the use of positive reinforcement may improve eating habits in children who present with FTT. If behavioral issues persist and are affecting nutritional habits in children with FTT it is recommended that the child see a psychologist. If an underlying condition, such as inflammatory bowel disease, is identified as the cause of the child's failure to thrive then treatment is directed towards the underlying condition. Special care should be taken to avoid refeeding syndrome when initiating feeds in a malnourished patient. Refeeding syndrome is caused by a shift in fluid and electrolytes in a malnourished person as they receive artificial refeeding. It is potentially fatal, and can occur whether receiving enteral or parenteral nutrition. The most serious and common electrolyte abnormality is hypophosphatemia, although sodium abnormalities are common as well. It can also cause changes in glucose, protein, and fat metabolism. Incidence of refeeding syndrome is high, with one prospective cohort study showing 34% of ICU experienced hypophosphatemia soon after feeding was restarted.

Low-resourced settings

Community-based management of malnutrition (CMAM) has been shown to be effective in many low resourced regions in the past two decades. This method includes providing children with ready-to-use therapeutic food (RUTF) and then following up with their health at home or at local health centers. RUTF is readily-consumed, shelf-stable food that provides all the nutrients required for recovery. It comes in different formulations, is generally a soft, semisolid paste, and can be sourced locally, commercially, or from agencies like UNICEF. In terms of efficacy, clinical experience and systemic reviews have shown higher recovery rates using CMAM than previous methods, such as milk-based formulas. While this is an efficient outpatient method to address FTT, children with underlying pathologies would require further inpatient workup. RUTF should be treated as prescribed medication to the child experience FTT, and thus should not be shared with others in the family. The recommended feeding protocol is 5-6 servings a day for about 6–8 months, at which time many children will fully recover. Children should have a follow-up every week or two looking at weight and upper arm circumference. Follow-ups can be decreased if there is progress without complications, but if the child is not improving, then further evaluation for underlying issues is recommended. After treatment has ended, the child's caretakers should be counseled on how to continue feeding them and looking for signs of relapse. Prevention is an effective strategy to address failure to thrive in resource limited regions. Recognition of at-risk populations is an important first step in approaching prevention. Infections such as HIV, tuberculosis and conditions causing diarrhea can be causative factors in failure to thrive. As such, addressing these conditions can greatly improve outcomes. Targeted supplementation strategies such as ready-to-eat foods or legume supplementation are valuable tools for preempting failure to thrive.

Prognosis

Children with failure to thrive are at an increased risk for long-term growth, cognitive, and behavioral complications. Studies have shown that children with failure to thrive during infancy were shorter and lower weight at school-age than their peers. Failure to thrive may also result in children not achieving their growth potential, as estimated by mid-parental height. Longitudinal studies have also demonstrated slightly lower IQs (3–5 points) and poorer arithmetic performance in children with a history failure to thrive, compared to peers receiving adequate nutrition as infants and toddlers. Early intervention and restoration of adequate nutrition has been shown to reduce the likelihood of long-term sequelae, however, studies have shown that failure to thrive may cause persistent behavioral problems, despite appropriate treatment.

Etymology of the term FTT

FTT was first introduced in the early 20th century to describe poor growth in orphan children but became associated with negative implications (such as maternal deprivation) that often incorrectly explained the underlying issues. Throughout the 20th century, FTT was expanded to include many different issues related to poor growth, which made it broadly applicable but non-specific. It was often used to blame the mother. The current conceptualization of FTT acknowledges the complexity of faltering growth in children and has shed many of the negative stereotypes that plagued previous definitions.

In older adults

The same label is given to older adults, as a synonym for frailty syndrome and functional decline. They may struggle with instrumental activities of daily living (e.g., preparing meals for themselves), be at high risk for hospital admission, and need significant discharge planning to support a safe and healthy return home.
