Living with Russell-Silver syndrome

A rare condition with slow growth before and after birth, feeding difficulties, and a small triangular face.

Understanding Russell-Silver syndrome

Russell-Silver syndrome is a rare condition marked by slow growth before and after birth.

Babies usually have low birth weight and may have trouble feeding and gaining weight. The head grows normally, so it can look large for the body. Some people have one side of the body larger than the other. Low blood sugar, reflux, and vomiting are common. Some have delayed motor skills, speech problems, or learning disabilities.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Slow growth after birth
  • Feeding difficulties and poor weight gain
  • Acid reflux and constipation
  • Small triangular face and downturned mouth
  • Uneven growth of arms or legs
  • Insulin resistance

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include bone and joint specialists, brain and nervous system specialists, cancer specialists and eye disease specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Little People of America may keep lists of experts for this condition.
