Asthma is a common health condition which affects the lungs. The severity of symptoms varies. Symptoms include coughing and wheezing. During an asthma attack, the lungs become inflamed and the muscles that regulate breathing become constricted, causing difficulty in breathing. Asthma attacks can be life-threatening for those with severe asthma. Asthma attacks can occur during stressful periods, exposure to pollen, exercising or when the air is cold. There is not conclusive evidence regarding what causes asthma.
Gastric bypass is one of the most effective ways of helping people who are morbidly obese to reduce their calorie consumption and lose weight. During the surgery, the surgeon cuts off the top of the stomach and seals it off from the rest of the stomach, reducing the amount of food that your stomach can hold. The doctor then cuts a small part of the ileum and attaches it to the stomach, which reduces the amount of food which will be absorbed by the body.
