Many foods and drugs contain aluminium (Al), which is absorbed by our bodies. Urine serves as the body's main method of excretion.

Metal fume fever may result from aluminium exposure. A metallic taste in the mouth, headache, fever, chills, pains, chest congestion and cough are some of the flu-like symptoms of this condition. After exposure, the symptoms may take several hours to manifest, and they often last one or two days.
