Allergic alveolitis

Allergic Alveolitis is a lung condition that results from an allergic reaction to the inhalation of certain dusts. The condition is also known as hypersensitivity pneumonitis, extrinsic allergic alveolitis, or farmer's lung when it is caused by exposure to moldy hay.

Causes

Allergic Alveolitis is caused by an allergic reaction to small particles or chemicals. The most common causes include exposure to certain types of dust, such as from moldy hay, bird droppings, or certain chemicals. The dust or chemicals can cause an allergic reaction in the lungs, leading to inflammation and damage.

Symptoms

The symptoms of Allergic Alveolitis can vary, but often include coughing, shortness of breath, and fatigue. Some people may also experience weight loss, fever, and night sweats. The symptoms can develop hours or even days after exposure to the allergen.

Diagnosis

The diagnosis of Allergic Alveolitis is often based on a person's history of exposure to certain dusts or chemicals and the presence of symptoms. Tests such as chest X-rays, lung function tests, and sometimes a lung biopsy may be used to confirm the diagnosis.

Treatment

The primary treatment for Allergic Alveolitis is avoidance of the allergen. This may involve changes in work practices for people who are exposed to allergenic dusts or chemicals at work. Medications such as corticosteroids may be used to reduce inflammation in the lungs.

Prognosis

The prognosis for Allergic Alveolitis can vary. Some people may recover completely if they avoid further exposure to the allergen, while others may develop chronic lung disease.
