Unfortunately, symptoms from lactose intolerance can last up to 48 hours depending on the amount of lactose you have ingested.

The onset of initial symptoms usually occurs within half an hour to two hours of ingestion. The length of time it will take your body to fully process the lactose you have eaten is dependent on your own chemical makeup, metabolism, and the amount of lactose-laden food you have eaten. If you have ingested lactose and are experiencing bad side effects, you can take an over-the-counter digestive aid to help you feel better.

Additionally, you can try taking a synthetic lactase product prior to eating dairy, which should help you better digest the lactose in the product. If your symptoms persist for more than 48 hours or become increasingly severe, you may need to seek medical attention.

Lactose intolerance occurs when your small intestine doesn't produce enough of an enzyme lactase to digest milk sugar lactose.

Normally, lactase turns milk sugar into two simple sugars — glucose and galactose — which are absorbed into the bloodstream through the intestinal lining.

If you're lactase deficient, lactose in your food moves into the colon instead of being processed and absorbed. In the colon, normal bacteria interact with undigested lactose, causing the signs and symptoms of lactose intolerance. There are three types of lactose intolerance.

Different factors cause the lactase deficiency underlying each type. People who develop primary lactose intolerance — the most common type — start life producing enough lactase. Infants, who get all their nutrition from milk, need lactase.

As children replace milk with other foods, the amount of lactase they produce normally drops, but usually remains high enough to digest the amount of dairy in a typical adult diet. In primary lactose intolerance, lactase production falls off sharply by adulthood, making milk products difficult to digest.

This form of lactose intolerance occurs when your small intestine decreases lactase production after an illness, injury or surgery involving your small intestine. Diseases associated with secondary lactose intolerance include intestinal infection, celiac disease, bacterial overgrowth and Crohn's disease.
