Does flu cause weight loss?

I've been sick with the flu for a few days now and haven't had much appetite. I've noticed I've lost a bit of weight. Does flu cause weight loss, or should I be looking into other reasons?

I feel flu can cause a little weight loss because you lose your appetite and get dehydrated. But it is usually just water weight and comes back once you eat normally, so don't worry too much.

Yeah man, absolutely. I lost almost 3 kgs when I had a bad flu last winter because I couldn't eat anything for four days. It's mostly just fluid loss and lack of food, nothing permanent.

Haan na, weight loss ho jata hai physically when we are so sick. Hunger completely dies during flu, but don't worry, once you start having normal meals, you will gain it back easily.

I completely understand why you are feeling anxious seeing the scale go down so fast. I also panicked when I lost weight during a bad bout of flu, but it's just because our bodies use so much energy to fight the virus.

It is very common to lose a couple of kilos during a severe flu. Your body is sweating out fluids with the fever, and your digestion slows down. Just focus on recovery now, weight will manage itself.

Oh absolutely, it happens to almost everyone when they get super sick. Don't stress too much about the weight loss right now, just focus on getting your strength back with warm soups and rest.
