Help! Losing weight with a genetic condition!

Hi lovely ladies :) I’ve been lurking in the background for a little while now, I have a genetic condition called Hypermobility Ehlers Danlos Syndrome, basically my joints can dislocate extremely easily and do on a daily basis, I want to lose weight, I’m around a stone and a half overweight, I have a boyish figure and do tend to accentuate that because well it’s comfy wearing baggy comfy clothes, so do you lovely ladies have any advice on how I can achieve my goal?
