Symptoms of gastroenteritis or stomach flu include abdominal cramps, stomach pain, nausea, vomiting, and diarrhea. You may also have fever, headache, and swollen lymph glands, depending on the type of bug that causes it.
In severe cases of gastroenteritis, loss of bodily fluid can result in dehydration, a life-threatening condition that needs medical attention. Signs of dehydration include sunken eyes, light-headedness, increased thirst, dry or sticky mucous membranes in the mouth, lack of normal elasticity of the skin, decreased urine output, and decreased tears.
I have this.
Was vomiting and shitting all night last night so it looks like I'm out of training for a few days. I'm feeling a bit better today but still have only managed to hold down gatorade. BJJ DVDs in the meantime, and hopefully back to training around thursday!
