Lactose intolerance may trigger symptoms such as bloating, gas and diarrhea after you eat or drink dairy products.

The National Institute of Diabetes and Digestive and Kidney Diseases says lactose intolerance could lead to:

• Uncomfortable digestive symptoms from being unable to digest lactose.
• Lack of calcium and vitamin D, triggered by insufficient dairy consumption.
• Development of osteoporosis, characterized by thinning, brittle bones that may break more easily.
