Yogurt, cottage cheese, milk, and cheese are some of the easiest ways to get protein when your appetite is small. They are soft, quick, and need little cooking. But if you are lactose intolerant, dairy can bring bloating, gas, cramps, and diarrhea. GLP-1 medications can cause many of the same symptoms, which makes it hard to tell what is behind them.<\/p>\n
If you take Ozempic or another GLP-1 and have trouble with lactose, here is how to sort out your symptoms and still get enough protein.<\/p>\n
The prescribing information for Wegovy, which contains semaglutide, the same active ingredient as Ozempic, at a higher dose, reports that in clinical trials diarrhea was reported by 30% of people on the medication against 16% on placebo, and nausea by 44% against 16%. Bloating and gas were also more common. Lactose intolerance causes many of the same symptoms, usually within a few hours of eating dairy.<\/p>\n
A simple food and symptom log helps. For a week or two, note:<\/p>\n
If symptoms reliably follow dairy, lactose is a likely factor. If they cluster in the days after your injection or after a dose increase, the medication is more likely. Often it is both. Share the log with your provider.

Ask your pharmacist or provider whether they are right for you.<\/p>\n If you avoid dairy entirely, focus on:<\/p>\n Our guide on getting the most out of your GLP-1 treatment<\/a> covers why protein and strength training matter.<\/p>\n When your stomach is upset, plain foods such as rice, bananas, toast, broth, and eggs are often easier. Our guide on what to eat to minimize nausea<\/a> has more ideas.<\/p>\n Diarrhea from either cause can dehydrate you. The prescribing information for Wegovy warns about acute kidney injury due to dehydration, and notes that the majority of reported events occurred in people who had gastrointestinal side effects such as nausea, vomiting, or diarrhea. Sip water through the day, and consider an oral rehydration drink if diarrhea lasts. Seek care if you cannot keep fluids down, feel very dizzy, or have severe stomach pain that does not go away.<\/p>\n If you are about to step up a dose, it can help to keep your diet simple for a few days and go easier on dairy, so you can tell how the new dose affects you.
