Who is most likely to develop a boil?
Anyone can develop a boil. However, people with certain illnesses or medications that impair the the body's immune system (the natural defense system against foreign materials or microbes) are more likely to develop boils. Among the illnesses that can be associated with impaired immune systems are diabetes and kidney failure. Diseases, such as hypogammaglobulinemia, that are associated with deficiencies in the normal immune system can increase the tendency to develop boils.
Many medications can suppress the normal immune system and increase the risk of developing boils. These medications include cortisone medications (prednisone and prednisolone) and medications used for cancer chemotherapy.
Ewww boils....great! Thanks for the info though Roblyn...information is always good.
