Why does my face get fat when I am on my period?

Don't worry, I experience exactly the same as this every month, only in my face. It starts about 5 days before my period and lasts rigth up until the last day. I absolutely hate it so know how you are feeling. I have found that drinking water helps quite a bit, I tend to try to make sure I only drink water and nothing else, as anything else just seems to increase the bloating. I drink 2 to 3 litres a day and can definitely say this helps to reduce the bloating. Try to do this in the week running up to new years and cut out salty and sugary foods and you may find your face doesn't look too bad on the night. My face seemed to become even more so when I started taking the contraceptive pill as well, so I have been cutting down on carbohydrates also. Hope this helps and don't worry about the rude comments :)

The answers to this question are so ridiculously stupid

It's water retention. It's possible to get bloated or swollen anywhere on your body.

If it's on your face, try sleeping with your head elevated on a pillow. Cut back on salty/greasy/sodium packed foods. Drink 8-10 cups of water a day.

^Do this a week before(and while on) your period and you might notice a reduction in the swelling.

Fluids tend to build up when you sleep on a non-elevated surface so an elevated head will help fluids flow downwards. Salt and sodium can lead to water retention. Water will flush out the excess fluids.
