Lactose intolerance can cause moderate to severe digestive and gut issues. It is important, first, before changing your diet, to speak with a doctor to determine whether you have lactose intolerance or an actual dairy allergy. The symptoms may be similar, but a dairy allergy can be much more serious. However, if you think you have lactose intolerance, you may experience bloating, excess gas and other digestive problems. Symptoms of a dairy allergy are wheezing, vomiting, cramps, and skin conditions. Most with lactose intolerance experience some levels of diarrhea and nausea.


1. The Tolerance Test

One of the easiest ways to test for intolerance is to take a simple test. On an empty stomach, drink two full glasses of skim milk. If, within two to four hours, you begin to experience lactose intolerance symptoms (bloating, nausea, diarrhea, or otherwise upset stomach), you may have an intolerance. This is an easy way to determine a possible intolerance, but for actual confirmation, you will need to visit your local physician or dietician. In addition, if you involve a professional in the process, you will get more expert advice about diet changes and lifestyle.
