History
When evaluating a patient for insulinoma, you should take a detailed history of the presenting symptom (onset, duration, and progression), other associated symptoms, and a thorough past medical history review. Other specific areas of focus when obtaining the history are: Review of any family history of predisposing genetic disorders such as multiple endocrine neoplasia type 1 or von Hippel Lindau
Symptoms
Patients with insulinomas usually develop neuroglycopenic symptoms. These include recurrent headache, lethargy, diplopia, and blurred vision, particularly with exercise or fasting. Severe hypoglycemia may result in seizures, coma, and permanent neurological damage. Symptoms resulting from the catecholaminergic response to hypoglycemia (i.e. tremulousness, palpitations, tachycardia, sweating, hunger, anxiety, nausea) are not as common. Sudden weight gain (the patient can become massively obese) is sometimes seen. A neater list of symptoms would include:
- Anxiety
- Behavior changes
- Blurred vision
- Confusion
- Convulsions
- Dizziness
- Headache
- Hunger
- Loss of consciousness
- Rapid heart rate
- Sweating
- Tremor
- Weight gain
