Asthma is a chronic lung disease where the tissue and airways of the lungs become extremely sensitive to certain substances. When these substances are breathed in, the lungs become inflamed. The muscles around the airways tighten and squeeze the lungs, and passages within the lungs swell and tighten. The airways themselves produce mucus, which further clogs the tightened, swollen airways. A person having an asthma attack finds it very difficult to breathe, and a severe attack can even be fatal.

Asthma affects people of all ages, but people with asthma are most often diagnosed as children. Symptoms can include wheezing, a tight feeling in the chest, shortness of breath, and coughing. Some people have mild symptoms all the time, and some people have no symptoms at all, but everyone with asthma is susceptible to occasional severe attacks or flare-ups of symptoms when they are exposed to triggers. Triggers vary widely but can include:

• Allergens (dust mites, pet fur, mold, pollen, grass)
• Irritants (smoke, pollution, dust, chemicals)
• Viral infections
• Physical activity, especially outdoors
• Certain medications or chemicals in foods (aspirin, sulfites)

A urinary tract infection, or UTI, happens when bacteria enter the body through the opening where urine is normally released. The bacteria infect the lining of the urethra and bladder, turning them red and inflamed. This causes pain in the abdomen or pelvic area, a burning sensation during urination, a sense of urgency about going to the bathroom, frequent urination, and urine that smells bad and looks cloudy, or even contains traces of blood. If the urinary tract infection is severe, it may travel all the way to the kidneys, a more serious kind of UTI called pyelonephritis. Patients with this kidney infection might have blood in their urine, feel back pain, and develop a fever.
