Onychomycosis, the official term for toenail fungus, may appear to be a small aesthetic issue, but if left untreated, it can have major health effects. A podiatrist at Allegheny Health Network, Dr. Peter Joseph, cautions that ignoring an infected toenail could result in a number of consequences.
The warm, wet atmosphere found within shoes makes for the perfect habitat for the fungus to grow and spread. Even more worrisome is the possibility of a widespread infection, which poses a serious risk, particularly for people with compromised immune systems like those with diabetes. Cellulitis, a bacterial skin condition that can be fatal, can result from the fungus penetrating the skin and creating cracks. If the infection is severe enough, it may potentially enter the bloodstream and become fatal.
