IBS weight loss??

Yes, of course a severe episode of diarrhoea will cause weight loss. Obviously, if everything you eat is passing through you at a higher speed than usual you'll absorb less of it than you normally would. You'll also be losing more fluid than usual.

The excess fluid loss can - and should - be made up by drinking more than usual. This can be water, WEAK tea or coffee or any other non-alcoholic drink. If you drink strong tea and especially coffee, as well as certain sodas and so-called "energy drinks", the caffeine in them will act as a diuretic, which will make you lose even more fluid. (A diuretic is a substance that prompts your kidneys to produce more urine.) However, it's better not to overdo the sodas or fruit juices (even natural ones) as these contain a lot of sugar, which also acts as a diuretic. Diet sodas are just as bad, as they're often sweetened with sorbitol or similar chemicals, which can make diarrhoea worse.

And don't forget - anxiety is a well-known cause of diarrhoea in itself, as I'm sure you're aware. Try and take it easy, put your fears aside, and figure out what you can eat that won't make the diarrhoea worse. Maybe go a bit easy on fruit and green veg for a few days and eat a bland diet till this all calms down. But don't forget to reintroduce the fruit, veg and other high-fibre foods as soon as you can.

Diarrhoea causes you to lose fluids and nutrients which can cause weight loss. Anxiety can also cause weight loss.

Try Imodium to calm the diarrhoea; rice or bananas are also good for stopping diarrhoea.
