Managing Your Pheochromocytoma
Managing Your Pheochromocytoma: Understanding and Treating the Condition
Pheochromocytoma is a relatively rare tumor that originates in the adrenal glands, located above the kidneys. These glands play a crucial role in producing hormones that regulate various bodily functions, including blood pressure and fluid metabolism. Pheochromocytomas secrete hormones such as epinephrine or related compounds, which can lead to symptoms like high blood pressure, heart palpitations, headaches, and excessive sweating. Although pheochromocytomas are responsible for only a small number of hypertension cases, their impact on overall health can be significant.
Causes of Pheochromocytoma:
The exact cause of pheochromocytoma remains unknown. While most tumors are not linked to family history, around 10% of cases are associated with familial or hereditary endocrine tumor disorders.
Symptoms of Pheochromocytoma:
Common symptoms of pheochromocytoma include intermittent headaches, anxiety, palpitations (abnormal, rapid heartbeats), excessive sweating, high blood pressure, and heat intolerance.
Diagnosis of Pheochromocytoma:
Diagnosing pheochromocytoma involves a thorough assessment of medical history and physical examination by a healthcare provider. Blood and urine tests are conducted to measure hormone levels, with a 24-hour urine collection used to assess catecholamines. Certain substances, such as alcohol, caffeine, amphetamines, benzodiazepines, certain antidepressants, and lithium, should be avoided before the test, as they may lead to false high levels.
Imaging techniques like Magnetic Resonance Imaging (MRI), CT scans, and other tests may be employed to locate the tumor. In cases where pheochromocytomas are found outside the adrenal glands, whole-body imaging with special nuclear medicine tests may be necessary.
Treatment of Pheochromocytoma:
Over 90% of pheochromocytomas are located in the adrenal glands and can be effectively treated through surgery. Prior to surgery, medications to control blood pressure are often administered.
During tumor removal, temporary fluctuations in blood pressure readings may occur.
For malignant pheochromocytomas that have spread, surgical intervention may not be curative. Instead, a combination of chemotherapy, radiation therapy, and other treatments is utilized to manage the disease.
DOs and DON’Ts in Managing Pheochromocytoma:
DO:
- Inform your healthcare provider if you or your family members have a history of pheochromocytomas or endocrine tumors. Regular screening with blood or urine tests may be required for your family members.
- Seek medical attention if you experience vision changes, severe headaches, weakness on one side of the body, chest pains, or increasing palpitations.
- Report ankle swelling, shortness of breath, weakness, or dizziness when standing to your healthcare provider.
- Notify your healthcare provider if symptoms return after surgery.
DON’T:
- Engage in strenuous exercise until your pheochromocytoma has been removed.
- Expect that your high blood pressure will completely normalize after surgery, as some permanent changes may have already occurred in the kidneys and blood vessels.

Conclusion:
Pheochromocytoma is a rare tumor that originates in the adrenal glands and secretes hormones that can cause various symptoms, including high blood pressure, heart palpitations, and headaches. While most cases are not associated with family history, regular screening may be necessary for those with a family history of pheochromocytomas or endocrine tumors. Treatment typically involves surgical removal of the tumor, and in some cases, additional therapies may be employed to manage malignant tumors that have spread. Early diagnosis, effective management, and close collaboration with healthcare providers can lead to improved outcomes and a better quality of life for individuals with pheochromocytoma.
