Symptom Guide To Microscopic Polyangiitis

Loss of Appetite

Loss of appetite is another common symptom that falls under the 'constitutional' umbrella. The appetite loss doesn't appear to be caused by a concentrated problem with the stomach or gastrointestinal system, but is instead a product of the general feeling of unwellness. Microscopic polyangiitis ravages the entire body, inflaming blood vessels and damaging organs. It's possible some patients experience damage to their digestive system, but a more likely cause is a nauseous feeling. Frequent fevers are also common. Because these symptoms are usually related to a common cold or flu, many patients don't realize they're seriously ill until they're in danger. Patients often lose a significant amount of weight without trying due to their loss of appetite, since they aren't eating enough to effectively nourish their bodies.
