Dairy products are an excellent source of protein, which is essential to healing after surgery. Many people, though, find that consuming diary products can lead to constipation
after surgery. There is also evidence that dairy products can increase secretions in the lungs, so if you have a chronic
cough, it may be worthwhile to avoid dairy products in the short term.
If you can eat dairy products without becoming constipated, focus on low-fat items, such as skim milk, cottage cheese and yogurt. Cheese, low-fat or not, should be eaten in moderation until you can determine if eating it will cause you to become constipated.
