Lactose intolerance after surgery? I’ve ever had a problem with dairy and still generally haven’t since my lap 3 months ago. Around Christmas I had whole milk with coffee and experienced some bloating symptoms. Today I had whole milk with my coffee again and had serious bloating and gas increasing through the day which turned into nausea and vomiting tonight. I had barely anything else and suspect milk may be a new trigger for me. Has anyone else developed a lactose intolerance post surgery?
