If you experience stomach aches after ingesting dairy products, you may have lactose intolerance, or the inability to digest lactose properly. Because lactose intolerance is a chronic condition that can have serious side effects, it's a good idea to ask your doctor about a long-term solution. Your doctor may suggest adding over-the-counter lactase drops to certain dairy products before you consume them. However, if you need immediate relief from the symptoms of lactose intolerance, these over-the-counter options may help you feel better: Gas relief tablets can alleviate the discomfort that comes from built-up gas in your intestines. Antidiarrheal tablets can provide much-needed relief for an overactive digestive tract. An all-in-one stomach medication can address a wider range of symptoms and help you feel better quickly.
