Understanding the Challenge of Severe Malnutrition
Malnutrition is a global health issue encompassing undernutrition (wasting, stunting, and underweight), inadequate vitamin or mineral intake, and overweight/obesity. While the term covers a broad range of conditions, the WHO 10-step protocol focuses specifically on the most severe cases of undernutrition, known as Severe Acute Malnutrition (SAM), often characterized by severe wasting or nutritional edema. Children with SAM are extremely vulnerable and require immediate, carefully managed medical intervention to prevent death. The protocol addresses the complex physiological state of a severely malnourished child, who may experience complications like low blood sugar, hypothermia, and infection simultaneously.
The WHO 10 Steps for Managing Severe Malnutrition
The WHO protocol for managing severe malnutrition is a staged process designed to bring a patient from a critical, unstable state to full recovery. The steps are divided into three distinct phases: initial stabilization, rehabilitation, and follow-up.
Phase 1: Stabilization (Days 1–7)
During this initial, high-risk phase, the focus is on treating life-threatening medical complications. Key steps include:
- Treat/prevent hypoglycemia: Severely malnourished children are at high risk of low blood sugar. This is treated immediately with a 10% glucose or sucrose solution and frequent, small feeds.
- Treat/prevent hypothermia: Low body temperature is a sign of infection and can be life-threatening. The child is kept warm, with frequent monitoring and feeding.
- Treat/prevent dehydration: Rehydration is done cautiously using a special low-sodium oral rehydration solution for malnutrition (ReSoMal) to avoid circulatory overload, which is a major risk.
- Correct electrolyte imbalance: Malnourished children have imbalances of potassium and magnesium. These are corrected with appropriate supplementation, but diuretics are avoided.
- Treat/prevent infection: Due to a weakened immune system, all severely malnourished children are assumed to have a hidden infection and are treated with broad-spectrum antibiotics upon admission.
- Correct micronutrient deficiencies: Supplements of key vitamins and minerals like Vitamin A, zinc, and copper are provided. Iron is withheld initially until the child begins to gain weight, as it can worsen infections during the stabilization phase.
Phase 2: Rehabilitation (Weeks 2–6)
Once the child is stabilized, the rehabilitation phase begins, focusing on rebuilding lost tissue and stimulating growth. The key steps are:
- Start cautious feeding: The patient's feeding is gradually increased, transitioning from a low-lactose starter formula (F-75) to an energy-dense catch-up formula (F-100) or ready-to-use therapeutic food (RUTF) to promote rapid weight gain.
- Achieve catch-up growth: Through the increased feeding and nutritional support, the child's body begins to rebuild and grow rapidly. Monitoring weight gain is crucial to track progress.
Phase 3: Follow-up and Discharge Preparation (Weeks 2–6+)
Recovery is sustained through supportive care and preparation for a healthy life after discharge.
- Provide sensory stimulation and emotional support: Severe malnutrition can cause developmental delays. Providing a loving, stimulating environment with structured play helps the child’s mental and behavioral development. Maternal involvement is a key part of this process.
- Prepare for follow-up: Before discharge, parents or carers are educated on proper feeding techniques, continued sensory stimulation, and the importance of regular follow-up checks and immunizations to prevent relapse. A child is considered to have recovered when they reach 90% weight-for-length (equivalent to -1SD).
Comparison of Inpatient Care Phases
| Feature | Stabilization Phase (Days 1–7) | Rehabilitation Phase (Weeks 2–6) |
|---|---|---|
| Goal | Correct life-threatening conditions | Promote rapid catch-up growth and weight gain |
| Energy Intake | Lower energy and protein (e.g., F-75) | Higher energy and protein (e.g., F-100 or RUTF) |
| Fluid Management | Cautious, slow rehydration using ReSoMal | Increased fluids to support higher metabolic needs |
| Iron Supplementation | Withheld to avoid exacerbating infections | Started once the child begins to gain weight |
| Infection Treatment | Immediate broad-spectrum antibiotics | Specific treatment for any identified infection |
| Mental Support | Constant, but focused on basic care | Increased focus on sensory and emotional stimulation |
The WHO's Broader Approach to Malnutrition
Beyond the inpatient protocol, the WHO advocates for a comprehensive, multi-sectoral approach to addressing malnutrition in all its forms. Recent guidelines have expanded care, including protocols for infants under six months old and the use of community health workers to manage uncomplicated cases with ready-to-use therapeutic foods (RUTFs). Efforts also focus on strengthening health systems, promoting breastfeeding, and supporting access to nutrient-dense foods.
Addressing the root causes of malnutrition, such as poverty, lack of education, and food insecurity, is essential for long-term prevention. Interventions often involve social protection programs like cash transfers and nutritional education for caregivers. This holistic approach acknowledges that clinical treatment is just one piece of the puzzle and that sustainable solutions require community-wide and systemic changes.

Conclusion
The WHO's 10-step protocol is a life-saving framework for managing severe acute malnutrition in the most vulnerable populations, particularly young children. By systematically addressing the immediate medical crises, followed by a structured rehabilitation process and essential follow-up care, the protocol provides a clear path to recovery. However, its effectiveness is maximized when integrated with broader public health initiatives and community-based programs that tackle the underlying causes of malnutrition. Ultimately, the fight against malnutrition is a global effort that combines clinical expertise with widespread social and economic support to give every child a chance at a healthy life.
