Hello, i was just wondering why, sometimes when i fart it smells metallic?

Can vary frequently: The gas released rectally is related to the process of digestion and breakdown of the contents ingested. The smells will vary dramatically depending on the type of food, amounts, and the fluids ingested. It can be common to have smells of metallic nature or any number of smells. This is generally not an indication of anything bad. See your provider if other symptoms. Hope this helps.
