Lactose Intolerance FAQ

Stomach infections

Most cases that develop in adults are inherited and tend to be lifelong, but cases in young children are often caused by an infection in the digestive system and may only last for a few weeks. Some people may still be able to drink a small glass of milk without triggering any symptoms, while others may not even be able to have milk in their tea or coffee.

No single diet can prevent all symptoms of GERD, and food triggers are different for everyone. The foods you eat affect the amount of acid your stomach produces.

Believe it or not, most adults around the world can’t digest milk — 40% of humans stop producing enough lactase to digest milk between the ages of 2 and 5. Fructose intolerance is also a common cause of acid reflux.

Certain ethnic and racial populations are more widely affected than others. As many as 75 percent of all African-American, Jewish, Native American, and Mexican-American adults, and 90 percent of Asian-American adults are lactose intolerant.


  • Gastroesophageal reflux disease (GERD), a condition in which stomach contents back up into the esophagus, affects approximately 20 percent of the U.S. population.

  • Giving these patients a lactose load may be dangerous because they are more prone to the dehydration that can result from the diarrhea caused by the lactose.
  • Even older women and children who must avoid milk and foods made with milk can meet most of their special dietary needs by eating greens, fish, and other calcium-rich foods that are free of lactose.
  • Patients then drink a large amount of a liquid that contains 50 grams of lactose.

There’s a world of difference between the very common condition of lactose intolerance and the much rarer, and more dangerous, true allergy to milk. Living without stomach pain, gas, and bloating is uncomfortable. To feel better, watch what you eat and drink. Limiting your dairy will make your feel more comfortable.

In today’s article, let us have a look at some common questions,health problems, nutrition and health benefits of milk. If you do choose to replace dairy with plant-based alternatives, be sure to check the nutritional facts for the foods you enjoy. Only fortified soy beverages can adequately replace cow milk, since soy beverage is naturally rich in protein and various vitamins and minerals, and is fortified to provide a nutritional profile similar to cow milk.

A burp is an involuntary expulsion of wind (gas) by the stomach when it becomes distended from an excess of swallowed air. Eating rapidly, which can occur when you eat hot foods, gulping food and drink, drinking a lot of liquid with meals, chewing gum, smoking or wearing loose dentures all promote air swallowing. Some people, when swallowing saliva to relieve heartburn, swallow air at the same time. Other people swallow air without noticing it, especially when they are tense. Fizzy drinks including beer cause belching because they release gas (carbon dioxide) into the stomach.

If you have symptoms of lactose intolerance, a hydrogen breath test may help determine whether you have lactose malabsorption or your symptoms are caused by something else. Lactose intolerance is very common, affecting up to 70% of people worldwide. In fact, many people who think they have lactose intolerance because they’ve experienced the symptoms have been shown to absorb lactose normally. Summary Other reported symptoms include headaches, fatigue, eczema, and muscle and joint pain, but these have not been confirmed as true symptoms.

Choose your foods according to the Food Guide Pyramid to meet your needs. Neutral lactase is manufactured in a novel, acid-resistant form that rapidly passes through the stomach to deliver the active enzyme to the small intestine, the natural site of lactose metabolism. As shown in Figure 4, the complete digestion of lactose occurs within the small intestine, as neutral lactase immediately releases its glucose and galactose components for rapid absorption.

The exact changes you need to make to your diet depend on how sensitive you are to lactose. Some people are able to tolerate some lactose in their diet without any problems, whereas others experience symptoms after consuming food containing only a tiny amount of lactose.

Despite experiencing moderate-to-severe symptoms, many people with GERD continue to consume foods that trigger symptoms. Simply providing these people with a “foods to avoid” list is insufficient for achieving long-term symptom reduction. By providing step-by-step support and guidance, a health coach can help people with GERD better adhere to dietary guidelines and experience lasting improvements in their GERD symptoms. Acid reflux occurs when pressure causes gastric distention (stomach bloating) that pushes the stomach contents, including acid, through the LES into the esophagus.
