Weight gain when poorly

[Nikkiwu]

So I just started my weigh loss journey and lost half stone by a week before Christmas as planned. But I came down with a chest infection, bronchitis and flu and I weighed myself this morning and that half a stone had been regained. I don’t know how as not had an appetite. I am so deflated by this and would like to know how I can help myself get rid of this gain as I feel my hard work has been wasted.TIA

It's no big deal. Weight fluctuates even when on a downward trajectory so you shouldn't pay too much attention to individual readings. Just keep doing what you were doing.
