I think there’s something wrong with me

So

I swear there’s something wrong with my health wise

My gums are quite red despite I brush them 2 times a day and use mouth wash,

My I haven’t been able to gain weight like, since I started purity, I can’t gain weight easily and I don’t lost it like I’m quite skinny but want to gain weight but can’t ( have been struggling with this for 5+ years)

Do have a quite weak immune system like I do get ill easily

Any advice on what to do?

Edit: went to dentist, it’s just me being paranoid about my gums, they were fine!
