Hi, my name is wendy73! Should I claim PIP for underactive thyroid?

Hi @wendy73, welcome to the community  

PIP is all about how your conditions affect you in your daily life, so if you feel your condition is affecting you a lot it could be worth applying. There's some information about the descriptors they use to make decisions on the Citizens Advice website if you'd like to have a read through. 

I'll pop your post over to our PIP section where I'm sure our lovely members can offer you some advice and support should you have any questions.
