I cannot tolerate milk. Each time I drink milk, I have bloating and diarrhea. Is this a milk allergy?
Dr. Tobin: This is not a milk allergy. This reaction is typical for lactose intolerance. This is caused by not having the enzyme or protein to break down the milk protein. Sometimes using products with the enzyme lactase added, will allow you to have milk without symptoms. Lactose intolerance is usually seen in families of Mediterranean ancestry but can also occur after a severe infection of the bowel and as people age.
