Name of the Condition

• Extremely low birth weight newborn, less than 500 grams
• Also known as ELBW newborn.

Summary

• Extremely low birth weight newborns are infants born weighing less than 500 grams, which is significantly below the average birth weight for newborns. These infants often require specialized medical care due to their high vulnerability and developmental issues.

Causes

• Premature birth: The primary cause of extremely low birth weight is premature delivery, often before 22 weeks of gestation.
• Multiple pregnancies: Twins, triplets, or other multiples are more likely to be born prematurely and with low birth weight.
• Maternal health issues: Conditions such as preeclampsia, chronic hypertension, or infections during pregnancy can contribute to low birth weight.

Risk Factors

• Maternal age: Being a teenage mother or over 35 increases risk.
• Lifestyle factors: Smoking, substance abuse, and poor nutrition during pregnancy.
• Previous history: Previous pregnancies resulting in low birth weight.

Symptoms

• Very small body size, with little body fat.
• Difficulty in maintaining body temperature.
• Breathing and feeding difficulties.

Diagnosis

• Ultrasound and prenatal tests to monitor fetal growth.
• Postnatal physical examination and birth weight measurement.

Treatment Options

• Immediate postnatal care in a neonatal intensive care unit (NICU).
• Temperature regulation, respiratory support, and nutritional support (intravenous or tube feeding).
• Long-term developmental monitoring and interventions as needed.

Prognosis and Follow-Up

• Prognosis varies; survival rates have improved with advanced medical care.
• Regular follow-ups are crucial for monitoring growth, development, and managing complications.

Complications

• Developmental delays or disabilities.
• Increased risk of infections.
• Respiratory issues and other chronic health problems.

Lifestyle & Prevention

• Prenatal care: Regular check-ups during pregnancy.
• Healthy lifestyle: Balanced diet, avoiding harmful substances, and managing stress.
