Protein Energy Malnutrition (Severe Acute Malnutrition): Clinical Case Discussion & Key Learning Points
Model Case Presentation
Patient Demographics
Name: Master Rohan, Age: 2 years, Gender: Male, Informant: Mother (Reliable), Place: Rural, low-SES family
Chief Complaints
- Progressive weight loss and wasting — 4 months
- Swelling of both feet — 3 weeks
- Decreased activity and refusal to feed — 2 weeks
History Summary
Rohan was born as the third child in a family with food insecurity. He was breastfed for 6 months but complementary feeding was inadequate — primarily thin rice gruel, rarely with pulses or animal protein. Weaning was abrupt at 18 months when the mother became pregnant again.
Over the last 4 months, the family noticed progressive weight loss, reduced activity, and swelling of the feet that does not resolve by morning. He has had two episodes of loose stools in the last month. Hair has become thin, sparse, and discolored. Skin over buttocks shows reddish-brown patches with peeling. No fever currently. No cough or breathing difficulty. Immunization is incomplete — only BCG and OPV0 received.
No family history of tuberculosis. No consanguinity. The elder siblings are also underweight. Socioeconomic background: daily-wage laborers, ration card holder.

📝 History — Exam Q&A
PEM (Protein Energy Malnutrition): A spectrum of nutritional disorders caused by deficiency of protein and/or energy (calories).
SAM (Severe Acute Malnutrition): Defined by any ONE of the following (WHO criteria):
- Weight-for-Height (W/H) Z-score < −3 SD
- MUAC < 11.5 cm (in children 6–59 months)
- Bilateral nutritional (pitting) pedal edema
- W/H < 70% of median (older criterion)
MAM (Moderate Acute Malnutrition): W/H Z-score −2 to −3 SD, or MUAC 11.5–12.5 cm, without edema.
| Feature | Marasmus | Kwashiorkor |
|---|---|---|
| Deficiency | Both protein AND calories | Predominantly protein (with some calorie intake) |
| Age | 6–18 months (infants) | 1–3 years (post-weaning) |
| Edema | Absent | Present (bilateral pitting) |
| Wasting | Severe ("old man face", baggy pants) | Present but masked by edema |
| Appetite | Ravenous (hungry) | Anorexia (miserable) |
| Behavior | Irritable but alert | Apathetic, miserable |
| Skin/Hair changes | Absent or minimal | Present (flaky paint, flag sign) |
| Fatty liver | Absent | Present (hepatomegaly) |
| Serum albumin | Near normal | Low (<2.8 g/dL) |
| Prognosis | Better | Worse (higher mortality) |
💡 Marasmic-Kwashiorkor
Features of BOTH — severe wasting + bilateral edema. This is the most severe form with the worst prognosis.
1. IAP Classification (Weight-for-Age):
| Grade | Weight for Age (% of expected) |
|---|---|
| Grade I | 71–80% |
| Grade II | 61–70% |
| Grade III | 51–60% |
| Grade IV | <50% |
2. Wellcome Classification (Uses weight-for-age + edema):
| Category | % Expected Weight | Edema |
|---|---|---|
| Undernutrition | 60–80% | Absent |
| Kwashiorkor | 60–80% | Present |
| Marasmus | <60% | Absent |
| Marasmic-Kwashiorkor | <60% | Present |
3. Waterlow Classification (Wasting vs. Stunting):
- Wasting: Weight-for-Height (acute malnutrition)
- Stunting: Height-for-Age (chronic malnutrition)
4. WHO/CIAF (Current preferred): Uses W/H Z-score, MUAC, and presence of edema to define SAM/MAM.
UNICEF conceptual framework — three levels of causes:
- Immediate: Inadequate dietary intake, recurrent infections (diarrhea, respiratory infections)
- Underlying: Food insecurity, poor childcare practices, inadequate health services
- Basic (root): Poverty, poor education, social inequality, political factors
Specific risk factors in India:
- Early weaning / abrupt cessation of breastfeeding (new pregnancy)
- Inadequate complementary feeding (quantity, quality, frequency)
- Low birth weight, prematurity
- Recurrent diarrheal illnesses, intestinal parasites
- Low maternal education and birth spacing <2 years
- Lack of ICDS / health service utilization
- Breastfeeding: Duration, exclusivity (first 6 months?), frequency
- Complementary feeding: Age of introduction (should be at 6 months), types of food given (only cereals vs balanced diet), frequency and quantity
- Weaning history: Abrupt? Reasons (new pregnancy, maternal illness)?
- Animal protein intake: Milk, eggs, meat, fish
- Feeding practices: Who feeds, how much time, active vs. passive feeding
- Food security: Number of meals/day, seasonal variation
- Associated diarrhea: Frequency, consistency — gut malabsorption worsens PEM
Malnutrition and infection are mutually reinforcing:
- Malnutrition → impaired immunity (thymic atrophy, reduced T-cell function, impaired phagocytosis, reduced secretory IgA) → increased susceptibility to infections
- Infections → anorexia, increased catabolism, nutrient losses → worsening malnutrition
This bidirectional cycle is responsible for the high morbidity and mortality in SAM children. Breaking the cycle requires simultaneous nutritional rehabilitation AND infection treatment.
Alternating bands of pigmented (normal) and depigmented (pale/reddish) hair along the length of the hair shaft, seen in Kwashiorkor.
Mechanism: During periods of protein deficiency, melanin synthesis is reduced → hair loses pigment. During recovery (periods of adequate protein), normal pigmentation resumes. Recurring episodes create alternating bands, resembling a flag.
Significance: Indicates episodic/recurrent protein deficiency, not a steady state.
Classic (albumin) theory: Low protein intake → low serum albumin → decreased plasma oncotic pressure → fluid shifts to interstitium → edema. However, edema is not always proportional to albumin levels, suggesting additional mechanisms.
Modern theory (Oxidative Stress / Golden's hypothesis): Dietary deficiency of antioxidant nutrients (Zinc, Vitamin E, Selenium) → failure of antioxidant defense → free radical damage to cell membranes → increased capillary permeability and sodium/water retention → edema.
Additional factors:
- Impaired sodium excretion (reduced Na-K ATPase activity)
- Elevated ADH levels due to cortisol excess
- Lymphatic dysfunction
💡 Key Exam Fact
Edema in Kwashiorkor begins in the feet and ankles and progresses upward. It is always bilateral and pitting. Unilateral edema should suggest other causes.
Buccal fat pads (of Bichat) are discrete encapsulated fat deposits in the cheeks. They are the LAST subcutaneous fat depot to be depleted in malnutrition — even in severe marasmus, they are preserved for a while, giving the infant a seemingly normal face initially.
When the buccal fat pads are finally lost, the infant develops a characteristic "old man face" or "monkey face" (sunken cheeks, prominent cheek bones, wrinkled skin) — indicating very advanced, severe malnutrition.
🩺 Examination — Exam Q&A
Technique: Measure at the midpoint between the tip of the acromion process (shoulder) and the olecranon process (elbow) of the left (non-dominant) arm, with the arm hanging relaxed. Use a non-stretchable MUAC tape.
| MUAC (cm) | Classification | Color |
|---|---|---|
| < 11.5 cm | SAM | Red |
| 11.5 – 12.5 cm | MAM | Yellow |
| > 12.5 cm | Normal | Green |
Age range for MUAC: 6 months to 59 months. MUAC is the preferred screening tool in community settings as it requires no reference tables.
Known as "Flaky Paint Dermatosis" or "Crazy Paving Dermatosis":
- Earliest change: Areas of hyperpigmentation (dark patches)
- Later: Superficial desquamation, skin peels off in large flakes leaving pale, raw areas underneath
- Distribution: Pressure and friction areas — buttocks, perineum, inner thighs, groins; spares sun-exposed areas (unlike pellagra)
- Ulceration and infection: Raw areas can become infected (impetigo)
- Depigmented patches after healing
💡 Distinguish from Pellagra (Niacin deficiency)
Pellagra rash is on sun-exposed areas (face, neck — "Casal's necklace", dorsum of hands). Kwashiorkor rash is on pressure/friction areas.
Baggy pants refers to the appearance of redundant, wrinkled, loose skin folds hanging over the buttocks and thighs, resembling a sagging diaper or baggy trousers.
Cause: Severe depletion of gluteal subcutaneous fat and wasting of gluteal muscles — the skin that previously covered this fat hangs loose.
Significance: Indicates severe wasting (marasmus or marasmic-kwashiorkor); part of the classic "old man" appearance alongside sunken cheeks and prominent ribs.
| Eye Sign | Deficiency | WHO Grade |
|---|---|---|
| Night blindness (nyctalopia) | Vitamin A | XN |
| Conjunctival xerosis (dryness) | Vitamin A | X1A |
| Bitot's spots (foamy, triangular) | Vitamin A | X1B |
| Corneal xerosis | Vitamin A | X2 |
| Corneal ulceration (<1/3 cornea) | Vitamin A | X3A |
| Keratomalacia (>1/3 cornea) | Vitamin A | X3B |
| Corneal scar | Vitamin A (past) | XS |
| Xerophthalmic fundus | Vitamin A | XF |
🚨 Keratomalacia — Ophthalmic Emergency
Keratomalacia (corneal melting) can lead to permanent blindness within hours to days. Any child with SAM and corneal changes must receive immediate high-dose Vitamin A.
Hypothermia: Axillary temperature < 35°C (95°F) or rectal < 35.5°C. Use a low-reading thermometer. Check for cold extremities, skin mottling, and lethargy. SAM children lose heat rapidly due to lack of subcutaneous fat insulation and reduced thermogenesis.
Hypoglycemia: Blood glucose < 54 mg/dL (3 mmol/L) by glucometer. Signs include: sweating, pallor, lethargy, loss of consciousness, seizures. Often asymptomatic in SAM — always check routinely on admission, even without symptoms.
💡 Key Point
Hypothermia and hypoglycemia are the most common immediate causes of death in the first 24–48 hours of admission. They must be detected and treated simultaneously on arrival.
Standard clinical signs of dehydration (sunken eyes, skin pinch, dry mouth, reduced tears) are unreliable in SAM because:
- Sunken eyes: Already present due to loss of orbital fat
- Skin turgor: Already poor due to loss of subcutaneous fat — pinch test unreliable
- Edema in Kwashiorkor: May mask dehydration
Reliable signs to use in SAM:
- History of recent fluid loss (diarrhea, vomiting)
- Thirst (if child can communicate)
- Restlessness and irritability
- Cold/mottled extremities
- Weak rapid pulse
Rule: If diarrhea is present in SAM, assume some dehydration and rehydrate with ReSoMal (not standard ORS).
- Moon face: Generalized facial puffiness/edema — gives a round, plump appearance paradoxically in an undernourished child
- Parotid enlargement: Bilateral painless parotid gland enlargement (due to protein deficiency affecting salivary glands)
- Miserable expression: Apathetic, does not smile, avoids eye contact
- Sparse, dull, depigmented hair on the scalp
Hepatomegaly in Kwashiorkor is due to fatty liver (hepatic steatosis).
Mechanism:
- Protein deficiency → decreased synthesis of apolipoprotein B (ApoB)
- ApoB is essential for packaging triglycerides into VLDL for export from the liver
- Without ApoB → TG cannot be exported → accumulate in hepatocytes → fatty liver → hepatomegaly
Examination findings: Soft, smooth, non-tender hepatomegaly. Liver is enlarged but not hard (not cirrhosis).
Important: Fatty liver of Kwashiorkor is reversible with nutritional rehabilitation.
🔬 Investigations — Exam Q&A
Mandatory / Routine:
- Blood glucose — detect hypoglycemia (glucometer on arrival)
- Temperature — detect hypothermia
- CBC — anemia, infection (WBC), thrombocytopenia
- Serum electrolytes — hypokalemia, hyponatremia, hypomagnesemia
- Blood culture — sepsis (fever or hypothermia)
- Urine culture/urinalysis — UTI (common silent infection in SAM)
- Stool examination — parasites (Giardia, Ascaris, hookworm)
- CXR — pneumonia, TB
- Mantoux test — rule out TB
- HIV testing — SAM with recurrent infections / poor response
Optional (guided by clinical findings): LFT (fatty liver), RFT, serum albumin, malaria smear (endemic areas), sputum AFB, bone age.
| Investigation | Finding | Significance |
|---|---|---|
| Blood glucose | <54 mg/dL | Hypoglycemia — immediate treatment |
| Serum albumin | <2.8 g/dL (Kwashiorkor) | Reduced oncotic pressure → edema |
| Serum potassium | Low (hypokalemia) | Total body K deficit (despite normal serum K initially) |
| Serum magnesium | Low | Risk of arrhythmia; worsens hypokalemia |
| Serum sodium | Low or normal | Dilutional; AVOID sodium loading |
| Hemoglobin | Low | Multifactorial anemia (Fe, folate, B12 deficiency) |
| WBC | Variable | May be low even in sepsis (immune paralysis) |
| Serum phosphate | May fall after refeeding | Refeeding syndrome risk |
In SAM, severe immune dysfunction causes:
- Thymic atrophy — reduced T-lymphocyte production
- Impaired neutrophil function — defective chemotaxis, phagocytosis, and oxidative burst
- Leukopenia may be present even in active sepsis — the child cannot mount a leukocytosis response
- C-reactive protein (CRP) may also be falsely low due to reduced hepatic synthetic capacity
Therefore: SAM children may have serious bacterial infections with a normal or low WBC, no fever, and no obvious localizing signs. Assume infection is present and treat empirically. Blood culture is essential.
The appetite test determines whether a SAM child can be managed as an outpatient (OTP) or requires inpatient (NRC) care.
Method:
- Offer the child a standard therapeutic amount of RUTF (Ready-to-Use Therapeutic Food / Plumpy'Nut) in a quiet area over 30 minutes
- The mother/caregiver should encourage the child but not force-feed
Interpretation:
| Result | Criteria | Action |
|---|---|---|
| Pass | Eats ≥ 1/4 of the daily RUTF amount per session willingly | Outpatient management (OTP) |
| Fail | Refuses or eats < 1/4 amount | Inpatient management (NRC) |
Contraindication: Appetite test should NOT be done if the child has medical complications (severe edema, respiratory distress, altered sensorium, severe anemia).
| Anthropometric Index | Use | Indicates |
|---|---|---|
| Weight-for-Age (W/A) | Overall nutritional status | Underweight |
| Height-for-Age (H/A) | Chronic malnutrition | Stunting |
| Weight-for-Height (W/H) | Acute malnutrition | Wasting |
| MUAC | Screening, community | Acute wasting |
| BMI-for-Age | Older children (>5 yrs) | Overweight/wasting |
Catch-up growth in SAM: Monitor weight gain. Adequate catch-up = weight gain of > 10 g/kg/day in Phase 2. Weight gain of 5–10 g/kg/day = moderate. < 5 g/kg/day = poor response.
💊 Management — Exam Q&A
Divided into two phases:
Phase 1 — Stabilization (Days 1–7): Treat life-threatening complications
| Step | Action |
|---|---|
| 1 | Treat/prevent hypoglycemia |
| 2 | Treat/prevent hypothermia |
| 3 | Treat/prevent dehydration |
| 4 | Correct electrolyte imbalance |
| 5 | Treat/prevent infection |
| 6 | Correct micronutrient deficiencies |
| 7 | Start cautious feeding (F-75) |
Phase 2 — Rehabilitation (Weeks 2–6):
| Step | Action |
|---|---|
| 8 | Achieve catch-up growth (F-100/RUTF) |
| 9 | Provide sensory stimulation (play, emotional support) |
| 10 | Prepare for follow-up after discharge |
If conscious / able to swallow:
- Give 50 ml of 10% glucose or 10% sucrose solution orally immediately
- Then start feeding F-75 every 30 minutes for 2 hours
- Thereafter continue F-75 every 2 hours, day and night
If unconscious / unable to swallow:
- IV 10% dextrose 5 ml/kg bolus (NOT 25–50% dextrose — risk of phlebitis and rebound hypoglycemia)
- Then start F-75 by nasogastric tube as soon as conscious
All SAM children: Feed every 2–3 hours around the clock (including night) during Phase 1 to prevent recurrence.
🚨 Never use 25% or 50% dextrose in SAM children
High-concentration glucose causes rebound hypoglycemia and hyperglycemia. Always use 10% dextrose.
- Dress child warmly (including head), cover with warm blanket
- Place under a radiant warmer or in Kangaroo position (skin-to-skin with mother)
- Keep the room warm (>25°C), avoid draughts and wet clothing
- Feed immediately (feeding generates heat)
- Monitor temperature every 30 minutes until normalized
Treat concurrent hypoglycemia simultaneously — both conditions go together.
ReSoMal = Rehydration Solution for Malnutrition.
| Component | Standard ORS (WHO) | ReSoMal |
|---|---|---|
| Sodium (mmol/L) | 75 | 45 |
| Potassium (mmol/L) | 20 | 40 |
| Osmolarity (mOsm/L) | 245 | 300 |
| Magnesium | Absent | 3 mmol/L |
Why not standard ORS?
- SAM children have impaired Na-K ATPase activity → high intracellular sodium, total body potassium depletion
- Standard ORS with high Na can cause sodium overload → worsening edema, heart failure
- ReSoMal has less sodium and more potassium/magnesium to correct the specific electrolyte deficits in SAM
Rate: 5–10 ml/kg every 30 minutes for 2 hours (orally/NG), then 5–10 ml/kg/hour for 4–10 hours. Watch for signs of over-hydration (increased RR, increased edema, large veins, puffy eyelids).
🚨 Never use IV fluids for dehydration in SAM unless in shock
IV fluids can easily cause fluid overload and heart failure in SAM. Always prefer oral/NG rehydration with ReSoMal.
| Feature | F-75 (Starter) | F-100 (Catch-up) |
|---|---|---|
| Energy | 75 kcal / 100 ml | 100 kcal / 100 ml |
| Protein | 0.9 g / 100 ml | 2.9 g / 100 ml |
| Fat | 2.6 g / 100 ml | 5.4 g / 100 ml |
| Na content | Low | Low |
| Phase | Phase 1 (Stabilization) | Phase 2 (Rehabilitation) |
| Purpose | Correct metabolic abnormalities, prevent complications | Achieve catch-up growth |
| Volume | 80–100 ml/kg/day in 8–12 feeds | Gradually up to 150–220 ml/kg/day |
💡 Why low protein in F-75?
In Phase 1, metabolic processes are impaired. High protein loads overwhelm the liver and kidneys. F-75 provides maintenance nutrition while metabolic recovery occurs — it is NOT meant for growth.
All SAM children admitted to NRC receive empirical broad-spectrum antibiotics (due to impaired immunity and difficulty clinically diagnosing infection):
No apparent infection (no fever, no obvious source):
- Oral Amoxicillin — 25 mg/kg every 12 hours for 7 days
- OR Cotrimoxazole for 7 days
Severely ill (shock, hypothermia, lethargy, fever):
- IV Ampicillin + Gentamicin for at least 48 hours, then oral Amoxicillin
- Add Metronidazole if anaerobic infection suspected (abdominal distension, foul stool)
Antiparasitic: Albendazole (single dose 400 mg / 200 mg if <2 yrs) given after stabilization to all SAM children.
| Micronutrient | Dose and Duration | Key Note |
|---|---|---|
| Vitamin A | High-dose oral Vitamin A on Day 1 (100,000 IU if <12 months; 200,000 IU if >12 months) | Essential; only if not given in last 1 month |
| Folic Acid | 5 mg on Day 1, then 1 mg/day | Treat megaloblastic component of anemia |
| Zinc | Included in F-75/F-100; supplemental only if deficient | Reduces diarrhea duration |
| Copper | Included in therapeutic feeds | Deficiency causes anemia, skeletal changes |
| Potassium | 3–4 mmol/kg/day added to feeds | Correct total body K deficit |
| Magnesium | 0.3–0.6 mmol/kg/day | Correct before giving K (hypoMg worsens hypoK) |
| Iron | NOT in Phase 1; start only in Phase 2 | Early iron promotes bacterial growth, oxidative stress |
🚨 IRON is DELAYED in SAM
Iron supplements are contraindicated in Phase 1. Free iron promotes oxidative stress, favors bacterial growth, and worsens cell damage. Start iron only in Phase 2 after metabolic stabilization.
Definition: A potentially fatal shift in electrolytes (especially phosphate) that occurs when nutrition is restarted too rapidly after prolonged starvation.
Pathogenesis:
- Starvation → body adapts to low insulin, uses fat/protein → intracellular electrolytes (P, K, Mg) are depleted
- Refeeding → insulin surge → glucose uptake → phosphate, potassium, magnesium shift rapidly INTO cells
- Result: Hypophosphatemia, hypokalemia, hypomagnesemia
- Consequences: Cardiac arrhythmia, respiratory failure, neuromuscular dysfunction, hemolysis, cardiac failure
Prevention (the WHO 10-step approach inherently prevents this):
- Start with F-75 (low calorie, low protein) — do NOT give full feeds immediately
- Gradually transition to F-100 only after metabolic stabilization (days 7–14)
- Supplement potassium, phosphate, and magnesium before and during refeeding
- Monitor electrolytes after initiating nutrition
WHO discharge criteria from Nutritional Rehabilitation Centre (NRC):
- W/H Z-score ≥ −2 SD on two consecutive measurements
- No edema for at least 2 weeks
- Weight gain > 10 g/kg/day for 3 consecutive days
- Appetite is good (passes appetite test)
- No medical complications
- Caregiver trained in feeding and care
Before discharge: Immunizations completed, Vitamin A given, deworming given, RUTF supply provided for home, follow-up date given.
Follow-up: Weekly for 1 month, then fortnightly for 2 months at Outpatient Therapeutic Programme (OTP).
Edema in Kwashiorkor resolves spontaneously with protein rehabilitation and sodium restriction.
- Do NOT use diuretics — the child is already volume-depleted intravascularly; diuretics worsen electrolyte imbalance
- Restrict sodium intake (F-75 and F-100 are both low in sodium)
- Adequate protein in diet restores oncotic pressure → edema resolves
- Correct hypomagnesemia (worsens fluid retention)
- Monitor weight daily — rapid weight loss in Phase 1 = resolving edema (expected)
🚨 Do NOT use diuretics for edema in SAM/Kwashiorkor
This is a common error. Diuretics cause dangerous electrolyte loss (hypokalemia, hypomagnesemia) and can precipitate shock.
🔭 Recent Advances — Exam Q&A
RUTF is a lipid-based, energy-dense, micronutrient-fortified food used for outpatient rehabilitation of SAM.
Most common RUTF: Plumpy'Nut
- Ingredients: Peanut paste + skimmed milk powder + vegetable fat + sugar + mineral + vitamin mix
- Energy: ~500 kcal per 92g sachet
- Protein: ~13% of energy
- Does not require water for preparation — microbiologically safe, can be eaten at home
- Shelf life: 2 years at room temperature
- Dose: 200 kcal/kg/day in 3–4 divided doses
Local RUTF in India: Desi RUTF made from chana dal + groundnut + jaggery + oil + fortified micronutrients — approved as an alternative to imported Plumpy'Nut.
CMAM is a WHO-endorsed approach that allows most uncomplicated SAM children to be treated at home rather than in hospital, reserving inpatient care for those with complications.
Four components:
- Community Mobilization: Early identification of SAM children through community health workers (ASHA/AWW) using MUAC tapes
- Supplementary Feeding Programme (SFP): MAM children receive fortified blended foods at health centers
- Outpatient Therapeutic Programme (OTP): Uncomplicated SAM treated with weekly RUTF distribution at health facilities; weekly monitoring
- Inpatient Stabilization Care (ISC / NRC): SAM with medical complications requiring Phase 1 management
Advantage: Increases coverage (80–90% of SAM can be managed outpatient), reduces hospitalization burden, lower cost.
NRC is a dedicated inpatient facility within or attached to a government hospital where SAM children with complications are managed under the National Programme for Prevention and Control of Malnutrition (Government of India).
Criteria for NRC admission (any one):
- SAM with bilateral pitting edema (grade 2+ or more)
- Failed appetite test
- Any danger sign: unconsciousness, convulsions, severe dehydration, respiratory distress, high fever
- Severe anemia (Hb < 5 g/dL)
- Skin breakdown / skin peeling with raw areas
- Persistent vomiting / aspiration risk
- SAM with HIV, TB, or other complicated comorbidity
Stay: Typically 14–21 days. Both mother and child are admitted. Mother is counseled on feeding practices.
| Programme | Target Group | Key Intervention |
|---|---|---|
| ICDS (Integrated Child Development Services) | Children 0–6 yrs, pregnant/lactating women | Supplementary nutrition, immunization, pre-school education |
| PM POSHAN (Mid-Day Meal Scheme) | School children 6–14 yrs | Hot cooked meal at school to improve nutrition and enrollment |
| POSHAN Abhiyan (Mission POSHAN 2.0) | Under-5 children, adolescents, women | Convergence program — nutrition, sanitation, WASH; target to reduce stunting/wasting by 2%/yr |
| National Iron Plus Initiative (NIPI) | 6 months–19 years + women | Weekly iron-folic acid supplementation |
| Vitamin A Supplementation Programme | 9 months–5 years | Biannual high-dose Vitamin A (under Universal Immunization Programme) |
| MAA Programme | Infants + mothers | Promotion of breastfeeding and optimal infant feeding practices |
The WHO released updated guidelines on "Prevention and management of wasting and nutritional oedema (acute malnutrition)" in 2023 with key changes:
- Combined MUAC + W/H for diagnosis: Using both MUAC and W/H Z-score together identifies more children with wasting
- Expanded age range: Management recommendations extended up to adolescents and adults, not just under-5 children
- RUTF alternative formulations: WHO acknowledges locally-produced RUTF with reduced milk content as acceptable when quality-assured
- Simplified SAM/MAM protocols: "Simplified, combined" treatment approach — treating MAM and uncomplicated SAM with the same protocol in high-burden areas to improve coverage
- Greater emphasis on CMAM as standard of care over hospital-based treatment
Emerging research (including landmark studies by Gordon et al., 2013) shows that gut microbiome disruption is central to SAM pathophysiology:
- SAM children have an immature gut microbiome — dominated by pathogenic bacteria, reduced beneficial Lactobacillus and Bifidobacterium
- This "microbiome immaturity" contributes to Environmental Enteric Dysfunction (EED) — subclinical gut inflammation with malabsorption
- EED causes persistent stunting even after dietary rehabilitation
- Research on using specific probiotic strains (L. rhamnosus GG) and fecal microbiota transplant (FMT) is ongoing
- The MALED study showed EED markers (lactulose:mannitol ratio) correlated with stunting independently of dietary intake
