Alleviating uncomfortable symptoms of lactose sensitivity
Lactose Intolerance: Managing a Common Digestive Condition
Lactose intolerance is a common condition affecting a significant portion of the population, particularly in the United States where around 75% of people are estimated to be affected [1]. This condition arises when the body has difficulty breaking down lactose, a sugar found in milk, cheese, yogurt, and other dairy products [1].
The primary cause of lactose intolerance is a deficiency of the enzyme lactase, which is responsible for breaking down lactose into simpler sugars that the body can absorb [1][3][4]. This deficiency can be due to a natural decline in lactase production starting around age two, a condition known as lactase non-persistence [1][5]. Other causes include genetic factors, gastrointestinal diseases, small intestine surgery, premature birth, or infections affecting lactase production [2][5].
Common symptoms of lactose intolerance include bloating, gas, stomach cramps, diarrhea, nausea, and abdominal pain, typically occurring within 30 minutes to 2 hours after consuming lactose-containing foods or drinks [1][2][3][4][5]. These symptoms result from undigested lactose fermenting in the colon, causing gas production and abdominal distress [3][4].
Managing lactose intolerance focuses on balancing dietary lactose intake with symptom control. Dietary adjustments are key, with avoiding or limiting foods high in lactose such as milk, ice cream, butter, cheese, yogurt, and processed foods containing lactose being essential [1][3][5]. However, modern approaches encourage consuming tolerated amounts of dairy to maintain adequate calcium intake after consultation with a healthcare provider [5].
Taking lactase enzymes before consuming lactose-containing foods can aid digestion and reduce symptoms [1][2][4]. Lactose-free or low-lactose dairy products offer alternatives to standard dairy to prevent symptoms [1][2]. Some evidence suggests that probiotics may help, though more research is needed [2].
If someone experiences persistent pain, discomfort, or regular bouts of diarrhea, they should contact a doctor. Chronic diarrhea may lead to complications such as dehydration, malnutrition, weight loss, anemia, and acute kidney injury [1]. Over-the-counter (OTC) medicines may help ease the discomfort of lactose intolerance, but it is important to stop consuming lactose to prevent symptoms from persisting.
Soy, almond, or oat milk can be used as alternatives to dairy milk. A dietitian or health professional can help someone plan their diet and explore alternatives to foods and drinks that contain lactose. Potential complications of lactose intolerance may include osteoporosis due to lack of calcium.
It is advisable to consult a doctor before taking lactase products. Particular strains of Lactobacillus acidophilus may be more beneficial for people with lactose intolerance. Simethicone may help with symptoms of gas and bloating, but it does not inhibit lactose intolerance or cure it. Lactose-free or lactose-reduced milk and milk products are available as alternatives to regular dairy products.
In conclusion, while lactose intolerance is not dangerous, it can cause uncomfortable digestive symptoms. Managing it focuses on balancing dietary lactose intake with symptom control, often using supplements or lactose-free alternatives. If you suspect you have lactose intolerance, it is important to consult a healthcare professional for proper diagnosis and management.
