Hello Wendy
It’s disconcerting when you turn up with valid expectations and the opposite occurs! Your question is very commonly asked. Most recently it was responded to here!
Take a look, and if you have time you can explore the section on Weight Loss (in the General Hot Yoga Discussion threads) about 1/3 down the main forum page where you will find quite a bit about bloating. But it will probably be solved by the link above.
Whether or not you are doing yoga to lose weight, this problem DOES affect many yogis.
On a positive note, isn’t it wonderful that your food habits seem to have improved just since going to class?
It does occur to me that a small amount of indigestion could be occurring with food choices but primarily check out the other thread.
Namaste
Gabrielle 🙂
