How effective are probiotics in eczema?
Probiotic treatment is generally safe; however, it can lead to adverse effects including sepsis and bowel ischaemia. The precise risk of such events is difficult to quantify, but is likely to be very low for most people.
Eczema affects between 5 and 20% of people at some time in their life. People with eczema have different bacteria in their gut to people without eczema, and sometimes they have inflammation in their gut. It may be possible to treat eczema symptoms by changing the mix of gut bacteria or by reducing inflammation in the gut. One type of treatment that might achieve this is probiotics – live microorganisms taken by mouth, such as the Lactobacillus bacteria, found in unpasteurised milk and yoghurt.
