First of all hello to everyone, I am new here, I have HA and I need some help right now please!

So here goes - I have been weighing myself since January this year - I have till today lost about 3.3kg (eqiv to 8lbs) - my appetite has not changed at all, I have not started anything new,.....I have given up alcohol during the week for the last few months (approx 2/3 bottles of wine in 5/6days), I now only drink a Friday and sometimes a Saturday...petrified this is cancer starting now due to the weight loss, so in 6 months its 8lbs unintentional weight loss......... thats bad - something is definitely wrong with me.....right?

Has anyone else had the same weight loss & should I see the Dr?

Thanks
