It may or may not be related to a cause...
I understand your concern. Before I answer your question I think you should know that blood pressure is broadly of two types.
1. Primary hypertension
- where the cause is unknown
2. Secondary hypertension
- where the cause is established. Renal pathology, previous heart ailment, endocrine and metabolic disturnbances are the commonly known causes.
Cardiac blood tests and kidney
functions does not rule out pheochromacytoma. We require atleast serum catecholamine
and 24 hours urine VMA levels to exclude pheochromacytoma.
If your blood pressures are stable now, do not be overtly concerned. You can discuss about pheochromacytoma with your treating doctor the next time you seem him/her.
Let me know if you need clarifications.
