Catecholamine Tumor: Symptoms, Diagnosis, and Treatment Options

When your body makes too much catecholamine tumor, a rare growth that produces excess adrenaline and noradrenaline, often in the adrenal glands. Also known as pheochromocytoma, it can trigger sudden, life-threatening spikes in blood pressure, sweating, and heart palpitations. These tumors don’t show up on routine scans, and many people are misdiagnosed for years—mistaken for anxiety, panic attacks, or even menopause.

Most catecholamine tumors start in the adrenal glands, but some grow along nerve tissue in the neck, chest, or abdomen. These are called paraganglioma, a related tumor type that can also overproduce adrenaline and noradrenaline. Both types are often benign, but even non-cancerous ones can be deadly if untreated because of how they flood your system with stress hormones. The key signs? Unexplained high blood pressure, headaches that come in waves, drenching sweats with no reason, and a racing heart that won’t settle. If you’ve had three or more of these episodes without a clear trigger, you need testing.

Diagnosis isn’t simple. Doctors start with blood or urine tests to measure adrenaline, a hormone that boosts heart rate and energy and noradrenaline, a closely related hormone that tightens blood vessels. If levels are high, imaging like CT or MRI finds the tumor’s location. Genetic testing is also common—up to 40% of these tumors run in families linked to conditions like neurofibromatosis or MEN2 syndrome. Treatment? Surgery to remove the tumor is the cure in most cases. But before surgery, you need medication to block the hormones and stabilize your blood pressure—otherwise, the stress of surgery can trigger a fatal surge.

After removal, most people return to normal. But follow-up is critical—these tumors can come back, even years later. And if you’ve had one, your family members might need screening too. The posts below cover everything from how these tumors affect heart health, what drugs are used to manage symptoms before surgery, how genetic testing works, and what to expect during recovery. No fluff. Just what you need to know if you or someone you care about is facing this diagnosis.

Pheochromocytoma: What It Is, How It Causes High Blood Pressure, and Why Surgery Is Often the Cure

The Most Common Types of Vertigo: BPPV, Meniere's Disease, and Vestibular Neuritis

As a blogger, I recently explored the most common types of vertigo: BPPV, Meniere's Disease, and Vestibular Neuritis. I discovered that BPPV, or Benign Paroxysmal Positional Vertigo, is the most common and occurs when tiny calcium crystals in the inner ear become dislodged. Meniere's Disease, on the other hand, involves fluid build-up in the inner ear, leading to sudden and severe vertigo attacks. Vestibular Neuritis, which is caused by inflammation of the vestibular nerve, results in a constant sense of imbalance. Overall, these three conditions can greatly impact a person's quality of life, but with proper diagnosis and treatment, they can be managed effectively.

The Role of Hydration in Preventing Skin Chafe

As a blogger, I recently discovered the vital role hydration plays in preventing skin chafe. Staying hydrated not only helps our overall health, but it also maintains our skin's elasticity and suppleness. When our skin is well-hydrated, it reduces the friction that can cause chafing. I've personally found that drinking enough water and using a moisturizer can significantly reduce skin irritation. So, let's remember to keep ourselves hydrated for healthier and chafe-free skin!
