Von Gierke Disease: Causes, Symptoms, and Treatment
Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 2, 2026.
What kind of doctor treats Von Gierke Disease?
A pediatrician or family doctor often notices the first signs and starts testing. The main specialist is a metabolic doctor, often a geneticist. A liver specialist may also be involved, and the primary care doctor coordinates care. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
Von Gierke disease is a rare inherited condition affecting how the body stores and uses glycogen, the stored form of glucose. People with this disease lack enough of the enzyme glucose-6-phosphatase. Without it, the liver cannot release stored sugar into the blood, causing low blood sugar between meals and glycogen buildup in the liver and kidneys.
Symptoms
Signs often appear in the first few months of life. Low blood sugar can cause sweating, tiredness, irritability, and sometimes seizures. The liver becomes enlarged, making the belly look swollen. Children may have slow growth and weak muscles. Some develop high uric acid, which can cause gout and kidney problems.
Causes and who gets it
The disease is caused by changes in a gene called G6PC, or a related gene called SLC37A4. A child must inherit one changed copy from each parent, who usually show no symptoms. It affects about 1 in 100,000 babies.
How doctors diagnose it
Doctors often suspect the disease when a young child has low blood sugar and an enlarged liver. Blood tests can show low sugar, high uric acid, and high fat levels. Genetic testing can confirm the diagnosis.
Treatment
Treatment focuses on keeping blood sugar steady, mainly through frequent feedings of foods that release sugar slowly, such as uncooked cornstarch. Doctors may prescribe medicines for high uric acid or high blood fats. With careful management, many people reach adulthood.
When to see a doctor
Any child with repeated low blood sugar, a swollen belly, or slow growth should be seen promptly. Seek emergency care if a child has a seizure, is very hard to wake, or cannot keep food down during an illness.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance; a concierge doctor usually charges more and often works alongside insurance. Either can offer longer appointments and easier access, which helps with frequent monitoring. However, they should refer the patient to a metabolic specialist for treatment decisions, and to a liver specialist if complications develop.
Common questions
Can Von Gierke disease be cured?
There is no cure at this time. Treatment can control blood sugar and reduce complications, and how well a person does varies from person to person. Some patients eventually need care for liver problems, and a small number may need a liver transplant.
Can adults have Von Gierke disease?
Yes. With better treatment, many people with the disease now live well into adulthood. Adults may face long-term issues such as liver tumors, gout, or kidney disease, so regular follow-up care continues for life.
Can it be prevented?
Parents who carry the changed gene have a 25 percent chance of passing the disease to each child. Genetic testing and counseling can help couples understand their risk before or during pregnancy.
How is it different from other glycogen storage diseases?
Von Gierke disease is type I of several glycogen storage diseases, which are conditions that affect how the body stores sugar. Each type involves a different enzyme and causes different problems. Von Gierke disease is one of the more common types.
