Typically, a boil is developed when a hair follicle becomes infected. However, furuncle is also associated with some health conditions. These are known to be the most common causes of it. These conditions are the following: over-weight, low immunity, diabetes, acne vulgaris, and impetigo.

There are also some factors which are known as the probable causes of the development of furuncles. These may involve poor hygiene, hot and moist climates, and age. If you fail to take care of yourself and you fail to take a bath or wash your body every day, you have more chances to acquire this. It is because the bacteria may stick with your skin and you are exposed to contaminants in your everyday life. To avoid furuncles, you must maintain cleanliness and practice proper hygiene. Likewise, age is also a causative factor because elder persons tend to be more prone to infections than the younger individuals. They have poorer immunity so they are more likely to suffer from diseases and infections like this one.
