adrenal that worsens lying down

Overview

A pheochromocytoma is a rare, usually non-cancerous (benign) growth inside the adrenal gland, a small hormone-making organ on top of each kidney. This tumor can release too much adrenaline and similar hormones, which can cause sudden episodes of high blood pressure, a pounding heart, sweating, and headache. Some people notice these symptoms get worse when they lie down, bend over, or put pressure on their belly.

No, pheochromocytoma is very rare. It is found in fewer than 1 in 2,000 people with high blood pressure.

It can occur at any age but is most often diagnosed in adults between 20 and 50. Some people inherit it from their parents, so it can run in families.

Symptoms

Common symptoms

• High blood pressure, sometimes dangerously high
• Pounding headache
• Heavy sweating
• Rapid or irregular heartbeat
• Chest pain or shortness of breath
• Anxiety or a feeling of panic
• Trembling or tingling hands and feet
• Pale skin
• Symptoms that seem to start or worsen when lying down, bending, or pressing on the abdomen

Symptoms in children

• Children may have high blood pressure, excessive sweating, weight loss, and irritability or mood changes.

Symptoms in older adults

• Older adults may have less typical symptoms, such as weakness, confusion, or falls due to blood pressure changes. They may also experience symptoms only when lying flat.

Causes

Main causes

• The exact cause is unknown for most pheochromocytomas.
• Some cases are caused by gene changes (mutations) passed down in families.
• The tumor grows from cells in the inner part of the adrenal gland, which normally make adrenaline and noradrenaline.

Risk factors

• Having a family history of pheochromocytoma
• Having a genetic condition such as multiple endocrine neoplasia type 2 (MEN2), von Hippel-Lindau disease, or neurofibromatosis type 1

When to see a doctor

See a doctor urgently if:

• If you have episodes of headache, sweating, a racing heart, and high blood pressure, especially when you lie down or change position, seek medical care promptly.
• If you faint, have chest pain, or severe shortness of breath, call your local emergency number immediately.

Book a routine appointment if:

• If you notice new symptoms that worry you and match the descriptions above, make an appointment with your doctor.
• If your blood pressure is hard to control despite several medicines, ask your doctor about other possible causes.

Diagnosis

A doctor will take a detailed history, do a physical exam, and likely order blood and urine tests that measure adrenaline-related hormones. Imaging scans can then help find the tumor.

Tests that may be done

• Blood and 24-hour urine tests for metanephrines (breakdown products of adrenaline hormones)
• CT or MRI of the abdomen to look at the adrenal gland
• Genetic testing if you have a family history or certain clinical features

What to expect at your appointment

The diagnosis process can take time because many conditions cause similar symptoms. Be honest with your doctor about when your symptoms happen, including whether lying down triggers them. You may be referred to an endocrinologist, a specialist in hormones and metabolism.

Treatment

The usual treatment is surgery to remove the tumor, which often cures the condition. Before surgery, your doctor will give you medicines to control blood pressure and heart rate. Your healthcare team will build a plan that fits your needs.

Self-care at home

• Keep a diary of your symptoms and what triggers them, such as lying down or bending
• Take all prescribed medicines exactly as directed
• Avoid sudden movements or straining, which can raise pressure inside your belly
• Check your blood pressure at home if your doctor advises it

Medical treatments

Medical treatment focuses on controlling blood pressure and heart rate before and sometimes after surgery. Your doctor will likely prescribe medicines that block the effects of extra adrenaline hormones. These medicines are started slowly and adjusted under close monitoring. Never stop them abruptly. For tumors that cannot be removed, specialists may use other approaches such as targeted therapies or radiation-based treatments.

When is surgery considered?

Surgery to remove the adrenal gland containing the tumor is the main treatment for most pheochromocytomas. After successful surgery, many people have normal hormone levels and their symptoms go away.

Living with this condition

Living with a pheochromocytoma means working closely with your healthcare team, keeping your blood pressure stable, and knowing when to ask for help. Many people feel greatly better after treatment.

Lifestyle tips

• Learn relaxation techniques to manage stress, which can trigger episodes
• Tell all healthcare providers, including your dentist, about your condition
• Wear a medical alert bracelet or keep a card in your wallet if your doctor suggests it

Diet and exercise

There is no special diet that cures pheochromocytoma, but eating a balanced diet and drinking enough fluids can help steady your blood pressure. Avoid heavy lifting or intense exercise that puts pressure on your belly until your doctor approves. Ask your doctor which activities are safe for you.

Mental health and emotional wellbeing

Living with a rare tumor can feel overwhelming and cause anxiety, especially if symptoms are unpredictable. It is normal to feel worried or stressed. Talk to your doctor about counseling or support groups to help you cope.

Prevention

There is no known way to prevent a pheochromocytoma. If you have a family history, genetic counseling and regular check-ups can help catch it early.

Screening programmes

If you have a known genetic syndrome that raises your risk, your doctor may recommend regular blood and urine tests, as well as imaging, to detect tumors early.

Complications

If left untreated

• Dangerous spikes in blood pressure that can damage the heart, brain, or kidneys
• Stroke or heart attack during a sudden severe episode
• Heart rhythm problems
• If the tumor is malignant, it may spread and cause serious health issues

Long-term outlook

Although pheochromocytoma is rare, it is often curable with surgery. Even if a tumor cannot be removed, modern treatments can control hormone levels and help you live a full life. With proper medical care, many people return to their regular activities.
