What are the symptoms of a gallbladder attack?

The symptoms of 'gallbladder attacks' can be very varied. The most common symptom is just an upper abdominal vague discomfort of which you may just feel 'bloated' or have 'gas' in your belly. It usually happens after a meal even though the amount consumed may not be a lot. Occasionally, when there is acute inflammation of the gallbladder, then you will feel a more severe pain in the right side of the upper abdomen.
