How do I know if I have hyperinsulinism and what are the symptoms of hyperinsulinism?

Insulin may decrease your blood sugar. Patients with hyperinsulinism may show symptoms as following:

• Hunger
• Sweating
• Weakness
• Palpitations
• Diplopia, blurred vision
• Headache, dizziness
• Emotional instability, anxiety
• Confusion, stupor, even seizures, or coma and death.

Other health problems may also cause these symptoms. Only a doctor can tell for sure. A person with any of these symptoms should tell the doctor so that the problems can be diagnosed and treated as early as possible.

Who is at risk for hyperinsulinism?

• Pancreatic insulinoma: An insulinoma is a tumor in the pancreas which is an organ in the abdomen that can make insulin to regulate blood sugar level. Patients with insulinoma can produce too much insulin and may show a series of symptoms of hypoglycemia.
• Side effect of inappropriate treatment for diabetes: When receiving overdose of insulin or diabetes medicine, or not eating enough food with ordinary dosage, or suddenly increasing your exercise without increasing the amount of food you eat, patients with diabetes may appear symptoms of hypoglycemia.
• Patients are misdiagnosed with diabetes and given insulin when it is not needed.
• Obesity and consumption of a diet rich in carbohydrates are risk factors for this disease.

How to know you have hyperinsulinism?

• Blood tests of insulin and glucose: Hyperinsulinism is characterized by high blood levels of insulin and low levels of blood sugar even after a period of time without food (fast). Further more, an overnight fasting test a 72-hour in-hospital fasting study with serial measurements of insulin and glucose levels can be done to prove the diagnosis.
• Radioimmunoassay measures of insulin and its precursor: This method can be used for measuring the fasting insulin concentration and insulin precursor in the blood.
• Levels of proinsulin, C-peptide, and urinary sulfonylureas: The goal of this measure is to rule out self-administration of insulin or hypoglycemic drugs.
• Computed tomography (CT) and magnetic resonance imaging (MRI) scan: These imaging studies can be used to identify insulinoma. They can confirm the location of the tumor and show the organs near the pancreas.

When to seek urgent medical care?

Call your health care provider if symptoms of hyperinsulinism develop. If you experience either of the following symptoms, seeking urgent medical care as soon as possible:

• Confusion
• Stupor
• Seizures
• Coma
