In brief: Side effects

Antibiotics can irritate the lining of your digestive tract.
They also can kill the healthy bacteria in your intestines that keep everything in balance, leading to diarrhea and yeast infections. That's why it's important to only take antibiotics when they are medically indicated (i.e. For bacterial infections and not for viruses), and to take them correctly and finish the full course when you do.

In brief: VARIOUS

The macrolides (erythromycin & others) are 'pro-motility' drugs which means they make your stomach contract, causing pain.
All antibiotics kill bacteria in your body--even the 'good' bacteria. This change of bacterial 'flora' upsets the G.I. Tract causing diarrhea, cramps etc.. --so it best to not take antibiotics unless necessary and when taking them to finish the course to prevent resistence.

There are NO medications which do not have some potential for side-effects. Many are minimal, but any time you take a medication you must balance the risks versus the benefits. Some complications of meds keep doctors very busy.
