Kids and Asthma

Asthma is on the rise, according to the U.S. Centers for Disease Control and Prevention. Currently, about one in 10 children has asthma, making it the most common serious chronic disease of childhood. It is still not known why asthma is on the increase.

“Asthma attacks can cause serious medical problems, leading to missed school days and the unwanted distress and expense of emergency room visits or hospital stays,” says pediatrician Rebecca Fazilat, M.D., who is one of the physician leaders of the Palo Alto Medical Foundation’s Asthma Management Program. “Fortunately, many children with asthma do improve as they get older. If your child’s asthma does not get better, good asthma control can make this condition almost invisible and ensure lifelong good health.”

Ganesh Krishna, M.D., is an interventional pulmonologist with expertise in pulmonary critical care medicine, who practices at PAMF’s Mountain View Center. Dr. Krishna is an expert at bronchial thermoplasty and other highly specialized, minimally invasive pulmonary treatments.

What Is Celiac Disease?

What’s all the talk these days about gluten free food and gluten free diets?

Gluten is a protein found in foods containing wheat, barley or rye. The consumption of gluten by susceptible individuals causes celiac disease, which affects the digestive system. People with celiac disease who eat foods containing gluten experience an immune reaction that damages the lining of their small intestines. This damage interferes with the intestines’ ability to absorb certain nutrients. Over time this can deprive many of the vital organs of important nourishment.

The most common symptoms of celiac disease are abdominal pain, vomiting, bloating and diarrhea. Less common symptoms are depression, irritability, joint pains, upset stomach, cramps, rashes and weight loss. Infants and young children seem to have more of the digestive symptoms than do adults.
