Currently, for the treatment of pheochromocytoma, it is primarily important that once diagnosed with pheochromocytoma, one should promptly visit the local hospital to arrange surgical treatment as soon as possible. By surgically removing the pheochromocytoma, this prevents the excessive secretion of catecholamines, which can lead to a hypertensive crisis in patients. Therefore, clinically, after diagnosing and locating the pheochromocytoma, receiving surgical treatment can often achieve satisfactory therapeutic outcomes. Typically, appropriate preparations must be made before surgery. Generally, prior to the operation, it is crucial to actively administer medications such as alpha-adrenergic blockers, beta-adrenergic blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, vasodilators, and catecholamine synthesis inhibitors to effectively treat and stabilize blood pressure.

What should I do if pheochromocytoma causes excessive sweating?

Patients with pheochromocytoma generally exhibit profuse sweating, which is a manifestation of sympathetic excitement. This occurs because the capillary beds throughout the body of a person with pheochromocytoma are constricted, including the sweat glands. Thus, it is easy to exhibit these symptoms of sympathetic excitement, characterized by nervousness, heavy sweating, and weight loss. So, how should this be treated? The key is to treat the cause. In the clinic, after collecting some blood history, conducting various blood tests, and performing adrenal CT scans among other imaging studies, a clear diagnosis of pheochromocytoma is made. Then, we will use some alpha receptor blockers, one to lower the blood pressure to a normal range and another to dilate the capillary beds throughout the body. After this, we proceed with the related surgical treatment. Following the surgical removal of the tumor, symptoms such as sweating will gradually be relieved.

Malignant symptoms of pheochromocytoma

For pheochromocytoma, if not treated adequately, it often leads to severe hypertensive crises in patients, characterized by extreme spikes in blood pressure accompanied by profuse sweating, palpitations, shortness of breath, chest pain, and numbness in the limbs. Excessively high blood pressure can easily trigger pathological changes in the heart, kidneys, liver, and brain tissues, possibly leading to hypertensive brain hemorrhage, and even endangering the patient's life. Therefore, if pheochromocytoma is not managed and treated properly, it often results in critical illness and might even endanger the patient's life. It is recommended that once diagnosed, hospitalization should be sought promptly, and surgical treatment should be considered if necessary.

Pheochromocytoma hypertension medication

For pheochromocytoma, it is often recommended to use adrenergic receptor blockers for the treatment of hypertension. These can be divided into α-adrenergic receptor blockers and β-adrenergic receptor blockers. In addition, all other types of antihypertensive drugs can also be used frequently during treatment. For example, angiotensin-converting enzyme inhibitors and calcium channel blockers also play a helpful role in the treatment of pheochromocytoma. Besides pharmacological treatment, the fundamental approach is to perform qualitative and localization diagnosis, and after confirmation, to surgically remove the pheochromocytoma completely to fundamentally achieve therapeutic goals.

How is pheochromocytoma diagnosed?

For patients with pheochromocytoma, comprehensive examinations are necessary for diagnosis. For instance, measuring catecholamines and their metabolites in blood or urine can help determine if there is a noticeable increase in catecholamine levels. Furthermore, adrenal CT scans can be used to assess the condition, where in many cases, significant occupying lesions can be detected through adrenal CT scans. In addition, other related tests also hold diagnostic value and significance, such as magnetic resonance imaging, ultrasound, and related nuclear scanning tests, which can assist in qualitative and locational diagnosis.

Is pheochromocytoma a cancer?

Pheochromocytoma is not a cancer. It is a special type of tumor tissue that usually originates from the neuroectodermal chromaffin tissue. It can secrete catecholamines. Based on the specific origins of the tumor cells, it can be divided into types such as parasympathetic, paraganglioma, sympathetic, and ganglioneuroma. Most often, it presents with long-term hypertension, which can cause damage to the heart, brain, and kidneys due to prolonged hypertension, or severe increases in blood pressure can lead to hypertensive brain hemorrhage, thereby endangering the patient's life. Early treatment is often necessary.
