Lactose Intolerance Epidemiology Forecast 2025-2034

Lactose intolerance is a digestive condition in which the body cannot digest lactose (a sugar present in dairy products). It is estimated that around 30 million American adults experience some degree of lactose intolerance by the time they turn 20 years of age.

Lactose Intolerance Epidemiology Forecast Report Coverage

The “Lactose Intolerance Epidemiology Forecast Report 2025-2034” offers comprehensive information on the prevalence and demographics of lactose intolerance. It projects the future incidence and prevalence rates of lactose intolerance across various populations. The study covers age, gender, and type as major determinants of the lactose intolerance-affected population. The report highlights patterns in the prevalence of lactose intolerance over time and projects future trends based on multiple variables.

The report provides a comprehensive overview of the disease, as well as historical and projected data on the epidemiology of lactose intolerance in the 8 major markets.

Lactose Intolerance Disease Overview

In lactose intolerance, the body cannot properly digest lactose, a sugar found in milk and dairy products. This digestive condition occurs due to a deficiency in lactase, which is responsible for breaking down lactose in the small intestine. Primary lactose intolerance develops as people age due to a natural decline in lactase production. On the other hand, congenital lactose intolerance is a rare condition in which babies are born with little to no lactase enzyme. Although lactose intolerance is common worldwide, its prevalence varies significantly by region and ethnicity.

Lactose Intolerance: Treatment Overview

There is no cure for lactose intolerance, with the treatment primarily focusing on reducing symptoms by limiting lactose intake and supporting digestion. Over-the-counter lactase enzyme supplements are used by patients often before consuming lactose-containing foods to help break down lactose and manage symptoms. Lactose-free or reduced-lactose products are recommended for individuals with lactose intolerance to avoid symptoms. Some studies also suggest that probiotics may improve lactose digestion by promoting healthy gut bacteria.

Epidemiology

The lactose intolerance epidemiology section offers information on the patient pool from history to the present as well as the projected trend for each of the 8 major markets. The publisher provides both current and predicted trends for lactose intolerance by examining a wide range of studies. Additionally, the report covers the diagnosed patient pool for lactose intolerance and their trends. The data is broken down into specific categories, such as total prevalent cases in males and females, and total diagnosed cases across different age groups and patient pools.

• Lactose intolerance affects about 65% of the global population and is mostly observed among adolescents and young adults. The condition is rarely found in children younger than 5 years.
• It is reported that the primary form of lactose intolerance is the most prevalent, affecting nearly 70% of the world's population, though not everyone with it experiences symptoms. On the other hand, the congenital type of lactose intolerance is very rare.
• Studies show that babies born prematurely may develop lactose intolerance, while children born at full term typically do not show signs of this condition until they are around 3 years old.
• In the United States, lactose malabsorption is more common among African Americans, American Indians, Asian Americans, and Hispanics/Latinos. Thus, these racial and ethnic groups are also more prone to experience symptoms of lactose intolerance.

Country-wise Lactose Intolerance Epidemiology

The lactose intolerance epidemiology data and findings for the United States, EU-4 (Germany, Spain, Italy, France), the United Kingdom, Japan, and India are also provided in the epidemiology section.

The epidemiology of lactose intolerance varies between countries owing to differences in genetic factors, diet, cultural practices, and environmental influences, among others. Lactose malabsorption is more prevalent in certain regions. In African and Asian countries, most people are affected by the condition. However, in regions like northern Europe, many people have a gene that allows them to digest lactose post-infancy, making lactose malabsorption less common. In the United States, approximately 36% of people suffer from lactose malabsorption.

Scope of the Report

• The report covers a detailed analysis of signs and symptoms, causes, risk factors, pathophysiology, diagnosis, treatment options, and classification/types of lactose intolerance based on several factors.
