If left untreated, tuberculosis can lead to death. If it spreads through a person’s entire body, the bacterial infection can lead to serious health complications including heart diseases, metabolic dysfunction, and other severe problems. Tuberculosis can also cause sepsis, which is when your body has an extreme reaction to infection and damages your tissues. This can be fatal if not promptly treated.
