The main causes are:
- lack of air circulating
- friction between skin folds (where skin rubs against the skin)
This can lead to:
- a red or reddish-brown rash
- raw, itchy, or weeping skin with or without a smell
- cracked skin
Intertrigo (sometimes called candida intertrigo) can occur anywhere on the body where skin rubs against skin, such as between the thighs or on the underside of the belly or armpit.
A warm, moist environment encourages infection by either yeast, fungus, or bacteria. Sometimes swelling, sores and blisters can also occur.
If you think you have intertrigo, speak to your GP as there are other skin conditions that might look similar.
How the rash is treated depends on how severe it is and what’s causing it.
The aim of treatment is to:
- reduce the rubbing of skin on skin
- keep the area dry
- reduce inflammation and moisture
- treat any infection and stop it spreading
Other treatments such as barrier creams, steroid creams, anti-fungal creams, and antibiotic creams or tablets may also help. You can ask your GP or pharmacist about these.
