Question:
Can vomiting cause facial hives?

Tonight after eating (too fast) - I vomited. I noticed when I went to the bathroom shortly after that my face had broken out into red blothy areas resembling hives (or wheals). I had this happen a couple weeks ago. I woke up in the morning looking like this. I contributed it to my moisturizer. But thinking back, I remember that I had spent the evening before vomiting several times. Since it happen again today - I'm wondering if it is related. I've never had hives before in my life. What can be done for them? Any advise would be appreciative!    — mkukahiko (posted on July 5, 2009)

I think you are talking about petechiae not hives(I'm a nurse), and if you are then the force of vomiting can cause you to get little red petechiae on your face. This happened to me one time when I was in college. I vomited so hard and so often that I got little red "dots" on my face. I went to the infirmary to get checked out and the doctor told me that I had got the petechiae from the vomiting. If it is petechiae, there is nothing that can be done, they will go away on there on, if it is hives, which are large sore-like spots then I would suggest going to ER, to see if you are allergic to something. Hives usually means you are allergic to something and if you are allergic to something if you don't find out what it is, then it could lead to alot more serious problems. Hope this helps. Dorothy RN

Oh, I forgot to tell you what petechiae are. According to the doctor who treated me that day, petechiae are little blood vessels that "burst" because of the pressure in your face when you vomit. Dorothy
