A pre-procedure review helps the team coordinate preparation for a person with pheochromocytoma.

How can pheochromocytoma affect blood pressure?

Pheochromocytoma is a rare tumor that originates in the adrenal gland. Some produce catecholamines, substances that can affect blood pressure and heart rhythm. In these cases, episodes of elevated blood pressure, palpitations, sweating, or headache may occur. The frequency and severity vary; these symptoms alone do not confirm the diagnosis.

Myth: You only need to be cautious if your blood pressure is high all the time

Not necessarily. In some people, symptoms and changes in blood pressure occur in episodes; they may feel well or have different readings between episodes. A single normal reading does not rule out pheochromocytoma, and a high reading alone does not diagnose it. The treating team interprets symptoms, medical history, and indicated tests together.

Why is care planned before surgery or anesthesia?

Surgery, anesthesia, and certain procedures can trigger significant responses in the body. If there is an excess of catecholamines, changes in blood pressure or heart rhythm may occur and increase cardiovascular risk during care. An evaluation beforehand helps the team review the clinical situation, coordinate safety measures, and decide on the appropriate timing and setting for the procedure.

Myth: I can prepare my medication on my own

No. Preparation is prescribed individually and requires professional supervision. The team determines the appropriate management based on the clinical evaluation and planned procedure. Do not start, stop, or adjust medications on your own. If your symptoms change or you have questions about the plan, contact the professional overseeing your care.

Which professionals may coordinate care?

Depending on the situation, planning may involve endocrinology, anesthesiology, surgery, and other relevant professionals. The team reviews clinical information and coordinates evaluation and follow-up. Involving several professionals does not mean that everyone needs the same tests or plan: decisions are individualized.

What should you tell the team before a procedure?

Tell your healthcare team if you have a diagnosis or suspected pheochromocytoma before surgery, anesthesia, or a medical procedure, even if it seems minor. Mention any episodes you have had and the medications you take. If the procedure is already scheduled and the team does not yet know this information, contact them before the date so they can coordinate the evaluation.

When should you ask for guidance, and when should you seek urgent care?

If you have new or recurring episodes of elevated blood pressure, palpitations, sweating, or headache, contact your treating team promptly for guidance. These symptoms can have different causes. Seek urgent care for chest pain, difficulty breathing, fainting, or severe or persistent symptoms. This article cannot determine the cause or replace an urgent evaluation.

Share the diagnosis or suspicion before the procedure

If you or a family member has a diagnosis or suspected pheochromocytoma, inform the team before any procedure and ask who will coordinate the pre-procedure evaluation. Sharing medical history, medications, and recent changes helps the team plan care. Do not improvise measures at home or change treatment without professional guidance.

When to seek medical care

If symptoms persist, test results are abnormal, or you have questions about medication, arrange an individual assessment. Do not change treatment or doses without medical guidance.

Frequently asked questions

Do palpitations and headache mean I have pheochromocytoma?

No. These symptoms can have different causes and do not, by themselves, confirm pheochromocytoma. If they are new or recurring, request a medical evaluation.

Should I tell the team about pheochromocytoma before anesthesia or a procedure?

Yes. Inform the team providing care, even if the procedure seems simple. Knowing in advance allows them to coordinate the evaluation and preparation appropriate for your case.

What should I do if intense symptoms occur before the procedure?

For chest pain, difficulty breathing, fainting, or severe or persistent symptoms, seek urgent care. Do not try to address the situation by changing medications on your own.

Does this topic resonate with you?

Every case is different. Book a consultation to review your history, test results and goals with a personalized plan.
