Causes
The exact cause of insulinoma is unknown, but several factors may contribute to its development:
-
Factors that increase the risk of insulinoma include genetic conditions such as multiple endocrine neoplasia type 1 (MEN1).
-
Mutations in the pancreatic beta cells can cause tumors.
Symptoms
Hypoglycemia (low blood sugar levels) is a common symptom of insulinoma due to excessive insulin production.
-
Low blood sugar, especially after fasting or physical activity, is known as hypoglycemic episodes.
-
Low glucose levels cause confusion and dizziness.
-
During hypoglycemic episodes, excessive sweating and shaking may occur.
-
An intense feeling of hunger, often accompanied by irritability.
-
Low blood sugar can cause blurred vision.
-
Symptoms of weakness and fatigue include persistent tiredness and muscle weakness.
-
Hypoglycemia can cause seizures or loss of consciousness in severe cases.
Diagnosis
Several tests and procedures are required to confirm the presence of insulinoma and its effects on blood sugar:
-
Examining symptoms and medical history, as well as conducting a physical.
-
Detecting hypoglycemia and inappropriate insulin secretion during fasting by measuring blood sugar and insulin levels.
-
To locate a tumor, imaging techniques such as CT scans, MRIs, and endoscopic ultrasounds are used.
-
Hospital-based fasting test for monitoring blood sugar and insulin levels for 72 hours.
Treatment
Surgery is the primary treatment for insulinomas. Other treatments may be considered depending on the tumor's characteristics and the patient's condition:
-
A pancreatic insulinoma can be removed by surgery, which is the most effective treatment.
-
In the absence of surgery, diazoxide or octreotide may be used to manage symptoms and reduce insulin production.
-
Maintaining stable blood sugar levels requires frequent small meals and a balanced diet.
-
When the tumor is malignant and inoperable, chemotherapy or radiation therapy may be considered.
Prevention
Insulinoma cannot be prevented specifically, but general health practices can help:
-
A routine medical check-up is a great way to detect any abnormalities early on.
-
To support overall health, one should eat a balanced diet rich in fruits, vegetables, lean proteins, and whole grains.
-
Individuals with a family history of pancreatic tumors or genetic conditions like MEN1 should monitor their blood sugar levels regularly.
-
Be aware of the symptoms of hypoglycemia and seek medical attention promptly if they occur.
Conclusion
It is a rare but treatable condition that affects insulin production and blood sugar regulation. It is essential to recognize the causes, identify the symptoms, and seek timely diagnosis and treatment to manage this condition effectively. In order to detect and treat cancer early, it is important to maintain a healthy lifestyle and have regular medical checks.
