Hi Tatiana "Stomach-turning" describes a feeling of nausea. So you could say "The horror film was stomach-turning. There was so much blood!" It's something that makes you feel sick. Best wishes Carolina

to make someone feel sick, often because they are angry or upset about something: The sight of Joe eating raw fish is enough to turn your stomach. Just the smell makes my stomach turn. The amount of money she spends on designer clothes really turns my stomach.
