What causes asthma? The exact cause of asthma isn’t known. It’s possible that a combination of genetics and environmental exposures interact to cause asthma to develop, most often early in life. Risk factors for developing asthma include: Atopy, an inherited tendency to develop allergies Certain respiratory infections during childhood Contact with airborne allergens Exposure…

But if you’re one of the 25 million Americans with the breathing disorder, the take-away message is not that you should rely solely on dietary improvements. “One of the dangers here is that people pick up this headline and say, well, I don’t…
Based on studies of mice, experts at Columbia University Medical Center in New York City are suggesting that leptin, a hormone involved in energy metabolism, appetite, fertility, and building bone mass, may play a key role in the link between asthma and obesity — and possibly lead to development of a leptin-based treatment for weight-related asthma. The…
Patients with asthma have an increased risk for pulmonary embolism, show Dutch findings. In particular, patients with a severe case of the disease are most at risk. “This is the first time a link has been found between asthma and pulmonary embolism and we believe these results have important clinical implications,” said Christof Majoor (Academic Medical Center,…
A woman’s exposure to high pollen levels in late pregnancy increases the risk of earlyasthma in the child, according to a group of researchers at Sweden’s Ume- University in a recent study. A number of studies have previously shown that there is an association with being born during a pollen season and an increased risk…
Abstract (provisional) Background Objective measurement of airflow obstruction by spirometry is an essential part of the diagnosis of asthma or COPD. During exacerbations, the feasibility and utility of spirometry to confirm the diagnosis of asthma or chronic obstructive pulmonary disease (COPD) are unclear. Addressing these gaps in knowledge may help define the need for…
California’s effort to reverse urban sprawl and encourage denser development may mean more children will live closer to polluted high-traffic areas. A new study estimates that near-road air pollution is at least partially responsible for 8 percent of childhood asthma cases in Los Angeles County. The authors reported that their findings “suggest that there…
