Polyarteritis nodosa (PAN) is a rare disease that makes your blood vessels swell. It can affect the blood vessels that go to almost every part of your body, including your heart, kidneys, and intestines. It could keep your organs from getting enough blood.
PAN is very treatable, especially if it's caught early. Medication can protect your blood vessels from damage and help with your symptoms.
Polyarteritis nodosa can affect many organ systems. Some of the most common ones are your skin, peripheral nerves (nerves other than your brain and spinal cord), intestinal tract, kidneys, heart, and joints.
If you have PAN, you may have a wide range of symptoms, including:
• Appetite loss
• General ill feeling
• Sudden weight loss
