As someone who is a recovered bulimic I can tell you that laxatives don't cause weight loss - it's artificial loss that you shit out of yourself when you are so utterly disgusted with the binge you just did.
I remember once that I was so terrified of binging, I poured paint on all the food in the house and threw it away (the paint was to stop me getting it out of the bin and eating it). Such was my urge to binge that 10 minutes later I was literally taking paint covered biscuits out of the bin, scraping off the paint and stuffing the food in mouth. After my binge I felt so disgusted with myself I took laxatives and collapsed on the bathroom floor with shit coming out of myself. Laxatives are not pleasant for ED patients and they aren't something which actually helps us loose weight at all. They r just a method of making your stomach feel empty so you feel less disgusted with yourself. You cant really abuse them too much because the side effects are not pleasant. Must don't help weight loss and ED patients know that so they only bother with them in emergencies.
These glp 1s are a totally different ball game. They will PREVENT the binge in the first place, (which for some bulimics may actually be a good thing - we need research). But for anorexic people they will be the golden ticket they crave to keep the hunger at bay and enable them to get to extremely low and dangerous weights.
When I was at the height of my ed I could go a whole week eating NOTHING and drinking only water. But I was sooooo hungry and when the urge to eat was too strong I'd binge for up to days. If, in the midst of my fasting week I'd have been able to take a GLP1 that might stop me getting hungry, who knows how long I may have continued to starve and that could've resulted in anorexia and even death.
Yes, people talk of personal responsibility but when you have an eating disorder you can't just stop yourself starving and seeking out glp1s. Just like an obese person can't stop themselves giving in to hunger and binging.
I do firmly believe these drugs should only be available via face to face appointment with a GP. I don't know, but I'm pretty sure meds like antipsychotics and diazapam are only available via face to face consultation with a GP, so I don't see why GLP1s are any different.
