No it is not normal. See your physician right away. You could be getting gas, air or fluid buildup and it is not normal before, during or after exercise.
yes it is
no not usually. im not positive if its normal but maybe it should be checked out.
It is not a good idea to exercise on an empty stomach. There are no nutrients to fuel the exercise.
no, but you should be quite happy if you have though but make sure they are not too big. Lol at the question above. It is quite normal but it rarely happens. Remove by surgery or exercise.
exercise
yes
it normal to have a cold stomach during pregnancy
Only if your pregnancy was big enough say on the your second trimester but normally should go back to normal, mostly it would be your breasts that would be bigger for a month or so then back to normal.
a fishes stomach is as big as its eye
When you do push-ups, the pressure on your abdominal muscles can cause them to contract and tighten, which may lead to discomfort or pain in your stomach. This is a normal response as your muscles are working hard to support your body during the exercise.
The normal pH of the stomach is about 2-3 and is caused by a high concentration of HCl secreted by the parietal cells of the stomach.
EXERCISE!
