Our Facebook communities

We have two Facebook community support and advice forums for UK residents.

If you are an adult in the UK with an MCAS diagnosis or suspect that you have MCAS you join ouradult support group.

If you are a parent or carer of a child in the UK with MCAS or suspected MCAS you can join our parent support group.

Please note that if you do not complete the questions when requesting to join we will be unable to add you to the group.

This is in order for us to keep the groups a safe space for people who are living with MCAS and to avoid unwanted promotions or spam messages.

"I’ve definitely felt less alone during the past very difficult 3 years. Even though we don’t meet in person, knowing other individuals understand my situation is very important. Thank you "

Social media platforms

In addition to our Facebook communities, we have multiple social media platforms which provide a space for people with MCAS to come together, share experiences and talk to others who understand. You can follow us on our social media platforms for charity updates, information about services and resources and posts raising awareness about life with MCAS.

"This group has been an utter lifesaver for me. Less alone is a total understatement, this is a vital life line. Thank you for being there when much in this world makes us feel mislead and unheard."
