Note that the inch-based designations sometimes express the width in a decimal (26 x 1.75) and sometimes as a common fraction (26 x 1 3/4). This is the most common cause of mismatches. Although these size designations are mathematically equal, they refer to different size tires, which are NOT interchangeable.
Stomach bloating may at times occur immediately after a meal, within minutes or in rare cases while eating. The most common cause for this is due to air swallowing (aerophagia) or consuming carbonated drinks. In both these cases, it can be avoided to a large extent.
The stomach and the intestines have a limit to what they can comfortably fit and exceeding this limit causes a feeling of intense discomfort as the organs distend to allow the digested material through. Dietary choices can also contribute to a hard bloated stomach after eating. Foods rich in fiber will tend to cause bloating due to the process required to digest them. Alternatively, the manner in which food is consumed can also cause bloating.
