Although 90% of cases of pheochromocytoma occur in the adrenal glands, patients can suffer from a variety of symptoms. Patients may experience vision changes, chest pain, weakness in one side of the body, and severe headaches. They should also schedule regular screenings for family members and friends. Symptoms of pheochromocytoma may also include loss of appetite, fatigue, and weight loss.

Although pheochromocytoma symptoms are often attributed to the hormones secreted by the tumor, they may also be related to the proteins produced. Acute or chronic release of catecholamines can lead to complications, affecting any organ system. The release of catecholamines can result in an abnormal heart rhythm and severe elevated blood pressure. In rare cases, these chemicals may lead to heart failure or pulmonary edema.

Various pheochromocytoma symptoms can be related to the hormones produced by the thyroid or parathyroid glands. The most common of these symptoms includes palpitations, anxiety, sweating, and headaches. About 17% of patients experienced all of these symptoms. Some patients also developed a pheochromocytoma crisis. During these episodes, patients might also suffer from seizures. If they have been diagnosed with pheochromocytoma, they should undergo genetic testing.

If a family history of pheochromocytoma has been identified, genetic testing is likely to be indicated. However, pheochromocytomas may occur without a family history. In these cases, they are classified as sporadic, although some patients may have both. Genetic screening can also be indicated to rule out the disease. If genetic testing is done, pheochromocytoma can be detected before symptoms develop.

Blood catecholamine studies can detect the presence of pheochromocytoma in patients with a history of the disease. They also measure substances produced by catecholamine breakdown. Abnormal amounts of these substances in the blood are indicative of a disease of an organ or tissue. Patients with pheochromocytoma may experience these symptoms in combination with other conditions, such as chronic fatigue, or chronic infections.

High blood pressure is another symptom of pheochromocytoma, but it should not be the only symptom. In fact, a small percentage of pheochromocytoma patients report normal blood pressure. This fact alone should raise a red flag. Patients with high blood pressure may also experience heart attack or adrenergic crisis, although this does not necessarily mean pheochromocytoma.

Regardless of whether you experience the classic triad of symptoms, it's important to seek medical attention for your symptoms. Most cases of pheochromocytoma can be treated with targeted surgery. Although surgery can be painful, most pheochromocytomas are curable. The symptoms may vary from patient to patient, but it is important to know what to look for as a first step.

A pheochromocytoma develops in the chromaffin cells that line the center of the adrenal gland. These cells produce noradrenaline and adrenaline, which trigger the body's response to a perceived threat. In the case of pheochromocytoma, these glands become overactive and release more hormones than necessary, leading to dangerously high blood pressure and heart attacks.
