Condition Lookup
Sub-Category:
Hypoglycemia (Non-Diabetes Related)
Number of Conditions: 2
Insulinoma
Specialty: Diabetes and Endocrinology
Category: Pancreatic Endocrine Disorders
Sub-category: Hypoglycemia (Non-Diabetes Related)
Symptoms:
episodes of confusion; dizziness; weakness; sweating; palpitations; hunger; blurred vision; loss of consciousness
Root Cause:
A benign tumor of the pancreatic beta cells that produces excessive insulin, causing recurrent hypoglycemia.
How it's Diagnosed: videos
Clinical suspicion based on symptoms, confirmed by a supervised 72-hour fasting test demonstrating hypoglycemia with inappropriately high insulin levels, C-peptide, and proinsulin. Imaging (CT, MRI, or endoscopic ultrasound) is used to localize the tumor.
Treatment:
Surgical removal of the tumor is the primary treatment. In non-surgical cases, medical management focuses on controlling hypoglycemia.
Medications:
Diazoxide (reduces insulin secretion, potassium channel activator) and somatostatin analogs like octreotide (inhibit insulin release).
Prevalence:
How common the health condition is within a specific population.
Insulinomas are rare, with an estimated incidence of 1-4 cases per million people annually.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Associated with multiple endocrine neoplasia type 1 (MEN1) syndrome, though most cases are sporadic.
Prognosis:
The expected outcome or course of the condition over time.
Excellent with surgical removal; the majority of insulinomas are benign and curable. Rare malignant cases may require additional therapies.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Severe recurrent hypoglycemia leading to seizures, neurological damage, or death if untreated.
Reactive Hypoglycemia
Specialty: Diabetes and Endocrinology
Category: Pancreatic Endocrine Disorders
Sub-category: Hypoglycemia (Non-Diabetes Related)
Symptoms:
shakiness; sweating; palpitations; hunger; anxiety; confusion; drowsiness; fatigue
Root Cause:
Excessive insulin release following a meal, leading to a drop in blood glucose levels within a few hours after eating.
How it's Diagnosed: videos
Based on symptoms occurring 2-4 hours post-meal and resolved with carbohydrate intake. Mixed meal tolerance test (MMTT) or continuous glucose monitoring (CGM) may confirm diagnosis.
Treatment:
Dietary modifications, including frequent small meals, low glycemic index foods, and balanced macronutrient intake. In rare severe cases, medications may be used.
Medications:
Acarbose (alpha-glucosidase inhibitor to slow carbohydrate absorption) and in experimental settings, diazoxide to reduce insulin secretion.
Prevalence:
How common the health condition is within a specific population.
Common but underdiagnosed; exact prevalence unknown as many cases are self-limited and not reported.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
History of gastric surgery (e.g., Roux-en-Y gastric bypass), prediabetes, or other conditions affecting glucose metabolism.
Prognosis:
The expected outcome or course of the condition over time.
Typically manageable with dietary adjustments; long-term outcomes are excellent in most cases.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
If untreated, frequent hypoglycemia can lead to weight gain due to compensatory eating and impact quality of life.
