Diaper rash
A diaper rash is any rash on the skin area covered by a diaper. Synonyms include diaper dermatitis (dermatitis = inflammation of the skin), napkin (or “nappy”) dermatitis, and ammonia dermatitis. While diaper rash is generally thought to affect infants and toddlers, any individual wearing a diaper (for example, an incontinent adult) is a candidate to develop this dermatitis.
Inflammation of the skin
But almost every child (between 7 and 35%) gets diaper rashes from time to time. A diaper rash causes the skin to become red, irritated, broken, and very sensitive. Consequently, touching the skin can be very painful. The affected area can be paler or darker than the surrounding skin.
Peak age
Diaper rash mostly affects babies between the ages of 4 and 15 months, with the peak age for diaper rash being between 9 to 12 months. But also, adults who have to wear a diaper are a target for getting diaper rash.
Additionally
A baby/adult is also more prone to diaper rash when he/she has a cold or feels unwell for any other reason, because the body’s natural defenses are not working as well as they should at that time.
Advise
A baby’s rash may be something other than diaper rash, such as a yeast infection, psoriasis or impetigo. These rashes are worse than diaper rash, definitely when they are present same time as diaper rash. It is advised to call a pediatrician if a baby shows heavy symptoms without knowing what kind rash it is.
Fragrances and components of the diaper and wipes
Allergic reactions are a less common cause of diaper rash. Commonly proposed allergens are fragrances and components of the diaper and wipes. These regions often have well-defined zones of redness with superficial vesicles and erosions.
If the diagnosis of allergic skin reaction is suspect, skin-patch testing may be done to identify the offending agent. This is rarely necessary.
Most common culprit
Basically, anything that irritates the skin or alters the protective layer of the skin can cause diaper rash in babies and adults. While there are several broad categories of causes of diaper rash, contact irritation is the most common culprit.
