Chemical pneumonitis is a type of lung disease that occurs when the lungs become inflamed due to inhalation of harmful chemicals. This condition is also known as chemical pneumonia and is a subset of the broader category of pneumonitis.

Causes

Chemical pneumonitis is caused by the inhalation of harmful chemicals. These can include smoke, dust, vapors, fumes, and certain types of gases. The chemicals can be inhaled accidentally or intentionally, and can come from a variety of sources, including industrial processes, household products, and environmental pollution.

Symptoms

The symptoms of chemical pneumonitis can vary depending on the type and amount of chemical inhaled, as well as the individual's overall health and sensitivity to the chemical. Common symptoms can include coughing, shortness of breath, chest pain, and fever. In severe cases, chemical pneumonitis can lead to respiratory failure and death.

Diagnosis

Diagnosis of chemical pneumonitis typically involves a combination of medical history, physical examination, and imaging tests such as chest x-ray or CT scan. In some cases, a lung biopsy may be needed to confirm the diagnosis.

Treatment

Treatment for chemical pneumonitis primarily involves removing the individual from exposure to the harmful chemical and providing supportive care. This can include oxygen therapy, medications to reduce inflammation and manage symptoms, and in severe cases, mechanical ventilation.

Prevention

Prevention of chemical pneumonitis involves avoiding exposure to harmful chemicals. This can be achieved through the use of personal protective equipment in industrial settings, proper ventilation when using household chemicals, and awareness of environmental pollution.
