Frequently Asked Questions

❓ What is malnutrition in pediatrics?
Malnutrition in pediatrics is a condition where a child has deficiency, excess, or imbalance of energy, protein, or micronutrients, leading to poor growth, impaired immunity, and developmental delay.
❓ What are the main types of pediatric malnutrition?
The main types are undernutrition (wasting, stunting, underweight), protein–energy malnutrition (marasmus, kwashiorkor), micronutrient deficiencies, and overnutrition (obesity).
❓ What is the difference between marasmus and kwashiorkor?
Marasmus is severe calorie deficiency causing wasting without edema, while kwashiorkor is primarily protein deficiency causing edema, fatty liver, and skin/hair changes.
❓ What is severe acute malnutrition (SAM)?
SAM is defined by weight-for-height Z score < –3 SD, MUAC < 11.5 cm, or the presence of bilateral pitting edema.
❓ What is moderate acute malnutrition (MAM)?
MAM is defined by weight-for-height Z score between –2 and –3 SD or MUAC between 11.5–12.5 cm without edema.
❓ What are the common causes of malnutrition in children?
Common causes include inadequate dietary intake, recurrent infections (diarrhea, pneumonia), poverty, food insecurity, poor breastfeeding, malabsorption disorders, and chronic illnesses.
❓ Why are infections common in malnourished children?
Malnutrition weakens the immune system, making children highly susceptible to infections and reducing their ability to mount fever responses.
❓ What are the clinical signs of kwashiorkor?
Kwashiorkor presents with bilateral edema, moon face, flaky paint dermatosis, sparse discolored hair (flag sign), hepatomegaly, apathy, and poor appetite.
❓ What are the clinical signs of marasmus?
Marasmus presents with severe wasting, loss of subcutaneous fat, an old-man appearance, no edema, and usually preserved appetite.
❓ What is MUAC and why is it important?
MUAC (Mid-Upper Arm Circumference) is a simple screening tool for acute malnutrition; MUAC < 11.5 cm indicates severe acute malnutrition.
❓ What is the first step in managing a child with SAM?
The first step is to treat life-threatening conditions such as hypoglycemia, hypothermia, dehydration, and infections before starting rehabilitation feeding.
❓ Why is hypoglycemia dangerous in malnutrition?
Hypoglycemia can rapidly lead to seizures, coma, and death in malnourished children due to low energy reserves.
❓ What is ReSoMal used for?
ReSoMal is a special oral rehydration solution used for dehydrated malnourished children because it contains less sodium and more potassium than standard ORS.
❓ Why is iron supplementation delayed in SAM treatment?
Iron is delayed until stabilization because it can worsen infections and increase oxidative stress during the acute phase.
❓ What is F-75 formula in SAM management?
F-75 is a starter therapeutic milk used in the stabilization phase; it provides low protein and low sodium calories to prevent refeeding syndrome.
❓ What is F-100 or RUTF used for?
F-100 and Ready-to-Use Therapeutic Food (RUTF) are used in the rehabilitation phase to promote rapid catch-up growth with high-energy feeding.
❓ What is refeeding syndrome?
Refeeding syndrome is a metabolic complication caused by sudden aggressive feeding, leading to electrolyte shifts such as hypophosphatemia, hypokalemia, edema, and arrhythmias.
❓ What are the major complications of severe malnutrition?
Complications include hypoglycemia, hypothermia, severe infections, electrolyte imbalance, heart failure, developmental delay, and increased mortality.
❓ How can pediatric malnutrition be prevented?
Prevention includes exclusive breastfeeding for 6 months, adequate complementary feeding, immunization, micronutrient supplementation, deworming, and improving sanitation and food security.
