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.
Pulmonary Edema
Pulmonary edema occurs when excess fluid builds up in the lungs, making it difficult for oxygen to move into the blood. It can develop suddenly and cause severe shortness of breath, rapid breathing, coughing, and a feeling of suffocation. Acute pulmonary edema can be a medical emergency and requires prompt assessment and treatment.

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.
Pulmonary Edema
Diagnosis is based on symptoms, physical examination, oxygen measurements, and medical history. A chest X-ray or other imaging may show fluid in the lungs. Blood tests, electrocardiography, echocardiography, and additional investigations may be used to determine whether heart disease, infection, kidney problems, or another condition is responsible.
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.
Pulmonary Edema
Preventing pulmonary edema focuses on controlling its underlying causes. People with heart failure or high blood pressure should follow prescribed treatment and monitor their condition. Managing kidney disease, limiting excess dietary sodium when advised, avoiding smoking, and seeking prompt care for worsening breathlessness can help reduce the risk of serious episodes.
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.
Pulmonary Edema
Risk factors include heart failure or other heart disease, uncontrolled high blood pressure, kidney disease, previous heart attack, abnormal heart valves, severe infections, exposure to certain toxins, and conditions that cause rapid fluid accumulation. The risk also depends on the underlying condition responsible for the fluid buildup.
