Symptoms of lactose intolerance typically occur within two hours following dairy consumption, and they include flatulence, diarrhea and vomiting, according to WebMD. Individuals with an intolerance to dairy products may also feel bloated and notice a gurgling or rumbling sensation in their abdomens.
Additional symptoms of lactose intolerance include stomach cramps and queasiness, according to Healthline. The condition can develop due to the natural aging process and can also accompany illnesses such as inflammatory bowel disease and celiac disease. In certain cases, lactose intolerance is inherited, due to a faulty gene passed on during birth. Individuals may also become lactose intolerant following intestinal surgery.
While there is no cure for lactose intolerance, sufferers can manage their symptoms by limiting dairy product consumption and implementing alternative calcium sources such as broccoli, spinach, salmon and pinto beans into the diet, explains Mayo Clinic. Individuals may also find relief by taking over-the-counter dietary supplements that contain lactase enzymes prior to consuming milk products, as the enzymes may help to aid in digestion. Lactase liquid enzyme drops can also be added to full cartons of milk. It is important for individuals with lactose intolerance to check product labels on items such as cereal, salad dressings and powdered baking mixes prior to consumption, as these items may contain hidden lactose.
