The mycotoxins produced by black mold enter your body through the respiratory system and thus it is one of the systems affected most by the initial exposure. These toxins and spores irritate the mouth, throat, and nose and affect the mucous membranes of your lungs and sinus cavities. This causes inflammation and can eventually lead to pulmonary hemorrhage (bleeding lungs). These mold symptoms are usually very similar to allergic symptoms but are much more threatening to our lives. Black mold symptoms related to the respiratory system include coughing, wheezing, nosebleeds, runny nose, sore throat, and sinusitis. Other symptoms include inflammation of the mouth, lungs or throat and swelling of the lungs, which lead to shortness of breath and other respiratory infections.
