Overview
Lactose Intolerance
Lactose intolerance occurs when the small intestine does not produce enough lactase, the enzyme needed to digest lactose, the natural sugar in milk. Undigested lactose passes into the large intestine, where bacteria break it down and produce gas and other substances that can cause symptoms. Typical symptoms include bloating, abdominal discomfort, gas, and diarrhea after consuming lactose-containing foods. The severity varies between individuals and depends partly on the amount of lactose consumed and the degree of lactase deficiency.
Asthma
Asthma is a chronic condition in which the airways become inflamed and can narrow or become more sensitive to triggers. This may cause repeated episodes of wheezing, coughing, chest tightness, or shortness of breath. Symptoms can vary over time and may become worse during an asthma attack. Asthma can begin in childhood or adulthood and affects people of all ages.

Lactose Intolerance
Diagnosis is based on the relationship between lactose consumption and digestive symptoms. A healthcare professional may review dietary history and may recommend a temporary reduction in lactose followed by controlled reintroduction. A hydrogen breath test can help confirm lactose malabsorption by measuring hydrogen produced after lactose is consumed. Other gastrointestinal conditions may cause similar symptoms, so persistent or severe digestive complaints may require evaluation for alternative diagnoses.
Asthma
Asthma is diagnosed using the pattern of symptoms, medical history, physical examination, and lung function testing. Spirometry can assess how much air a person can breathe out and how quickly it moves through the airways. Additional testing may be used when the diagnosis is uncertain or to identify allergic or other triggers. Symptoms and lung function are considered together.
Prevention
Lactose Intolerance
Primary lactose intolerance related to genetically determined lactase reduction cannot generally be prevented. Secondary lactose intolerance may improve when the underlying intestinal condition is identified and treated. People who experience symptoms can often reduce discomfort by adjusting the amount and timing of lactose consumed rather than unnecessarily eliminating all dairy foods. Adequate calcium and vitamin D intake should be maintained through tolerated foods or appropriate alternatives, particularly when dairy consumption is reduced.
Asthma
Asthma cannot always be prevented, but attacks can often be reduced by identifying and avoiding personal triggers and following an individualized treatment plan. Avoiding tobacco smoke, reducing exposure to known allergens or irritants, managing respiratory infections, and taking prescribed medicines as directed can help control symptoms. Regular follow-up is important when symptoms are persistent or changing.
Risk Factors
Lactose Intolerance
Risk depends on the underlying type of lactose intolerance. Primary lactase reduction is common with increasing age in many populations. Secondary deficiency may occur after intestinal infections, inflammatory disorders, or other conditions that affect the small intestinal lining. Genetic background also influences lactase persistence into adulthood. The amount of lactose consumed, the food in which it occurs, and individual digestive tolerance affect whether symptoms develop.
Asthma
Risk factors include a family history of asthma, allergies, exposure to tobacco smoke, certain workplace chemicals or dusts, repeated viral respiratory infections during childhood, and obesity. The likelihood of asthma may also be influenced by environmental conditions and individual sensitivity to allergens or irritants. Risk factors and triggers differ between people.
