Venus Legacy

Can treatments to flatten stomach such as using Venus legacy cause indigestion and gas problems? I have had gastrointestinal issues in the past but found ways over the years to prevent flare ups, by cutting out milk, ice cream, & added probiotics. Presently just had one venus legacy treatment (tx) w/heat which maybe 2-3 hours later had nausea and bowel movements. Off and on stomach pain came a day or two later w/gas. Not sure if I should get the other 7 tx thinking it could cause me major gastrointestinal problems.
