Hisflower's answer ( sorry I deleted this by mistake as I am new to this. He or she said the GP is probably sick and should see a vet)
Guinea pigs can't vomit. I wonder if what you are seeing is the heaving hiccoughs as described by Peter Gurney.
Alternatively, one of my guinea pigs went through a spell of spitting out brown fluid when I was trying to hand feed it when it was sick. I am pretty sure now that this was the result of it eating every poop in sight (not just the special ones) in order to try and restore its gut flora. It was on Baytril at the time.
Guinea Pigs CANT throw up. Any thing that goes in must come out the back way. If your guinea pig keeps coughing, pat it gently on the back and give its cage a big clean out. Some times your guinea pig might even have hiccups!
They don't exactly "throw up". Sometimes they do that probably to decorate a cage, or was storing some food in their pouches and then threw them out again for a reason.
Guinea pigs have the instinct to hide because in the wild a lot of animals like to eat them. This is natural behavior and does not mean they do not like you.
When your guinea pig tilts its head to one side it might have a eye or ear infection.
It is spelled "guinea pig". You got it right! :)
I think your guinea pig is dieing. I am part of a 4-H group and I study rabbits and guinea pigs. My rabbit died last year and had the same syptoms.
The phenotype of the black guinea pig is black, and the pheno type of the white guinea pig is white.
One would be crying and throwing his or her guinea pig
nothing
Then your guinea pig has probablly a serious disease

take it to the doctor
It is helpful because it keeps you company
My guinea pig always falls over when I brush her so I may be brushing her to hard or she has something wrong with one of legs.somtimes your guinea pig could have a ear infection and may fall over because of that if somthing is wrong or if your guinea pig will not stand up please take it to the vet as fast as you can and keep your guinea pig warm

Take your guinea pig to the vet if something seems wrong...
well, maybe your guinea pig is feeling sad, mad, or maybe he wants you to play with him/her more. It probably puts its head down because it's feeling sad. ~court well my guinea pigs sick that could be it and i suggest bringing her to the vet i did and my guinea pigs really sick
his spleen is about to burst
