A yeast infection occurs when levels of the fungus candida albicans, which exists naturally on the human body, become excessive and overgrown. In some cases, the overgrowth becomes a severe yeast infection, where the amount of yeast is so high it becomes painful and difficult to cure. These infections can occur in many places in the body, including the mouth, skin, or intestines, though they are commonly associated with the vagina in women. They may result from an existing infection that is left untreated, or because a person's immune system in unable to effectively fight off the excess yeast. Infections that reach this level of severity generally require medical treatment to clear them up.
While a normal yeast infection is often merely itchy and irritating, a severe yeast infection is normally far more uncomfortable and debilitating. It is often extremely painful, causing swelling, intense itching, and a burning sensation. Depending where in the body it occurs, the infection can also lead to other issues like throat lesions and difficulty swallowing, leaky gut syndrome, or painful urination. Women with vaginal infections will typically notice a thick, strong-smelling discharge, and often experience pain during sexual intercourse. Severe yeast infections tend to be difficult to treat, often lasting more than a week; they may also tend to recur over and over.
A yeast infection may become severe for a variety of reasons. People with compromised immune systems or autoimmune diseases may be unable to fight off a normal yeast infection easily. Those with diabetes are also often susceptible. An infection that is left untreated may progress into a severe yeast infection. Improper treatment may also be to blame; for example, if the issue is misdiagnosed and antibiotics are given, this can aggravate the condition and make it worse.
Treatment of a severe yeast infection typically requires a doctor's assistance. Often, prescription-strength medication is necessary to clear them; Diflucan is one common drug that may be used and can be given at different strengths depending on the severity of the infection. There is a possibility that a person can become immune to certain drugs if they are used excessively, however, so doctors may have patients alternate medications if infections are recurring. Some over-the-counter medications may be useful as well, but patients should usually consult with their doctor before starting treatment to ensure they are taking the best course of action.
