I've both gained and lost weight over the last few years. Before I got very sick I was increasingly losing my appetite - rarely hungry apart from sometimes craving fat/sugar (sugar seemed to make my headaches better). But, even though I was hardly eating anything my weight increased from it's usual (stable for a decade) 8 1/2 stone up to about
9 1/2 stone. It all seemed very odd.
Then, when I started antibiotic treatment I gradually lost the extra weight. Unfortuantly I am still losing weight even though my appetite has returned with a vengence. I'm now down at 7 1/2 stone which is not ideal at all. I am not taking much sugar but other than that just a normal diet. I suspect the antibiotics perhaps make me lose weight...
