Some issues Dr. Alex Leung, MD can help you with:

Anxiety

Anxiety is a generic name given to a variety of conditions characterized by unusual amounts of fear and worry, especially unrealistic fears and tension. People who suffer from anxiety often are aware that their fears are irrational, but that knowledge does not make the feeling of being scared and anxious go away. To qualify as anxiety, symptoms must last for 6 months or more and interfere with the way a person lives their daily life. Some cases may be mild, where, for example, a person simply avoids certain situations. Other cases can be severe enough to be disabling.

Some of the specific conditions covered under the general label of anxiety include:

Generalized anxiety disorder
Obsessive-compulsive disorder
Phobias
Post-traumatic stress disorder
Social phobia
Panic disorder

Collectively, anxiety disorders are the most common mental health issues diagnosed in the United States -- even more common than depression. Women are more likely than men to be diagnosed with anxiety, and it is extremely common for a person with anxiety to have another illness at the same time, such as depression, a physical illness, or substance abuse.

Treatment for anxiety usually involves medication and psychotherapy together. Medications used may include antidepressants (which also work for anxiety), anti-anxiety medications, or beta blockers (which can be used to control the physical symptoms of anxiety). Psychotherapy can be useful to teach patients new ways of thinking and reacting so that they can manage their feelings of worry and fear. Support groups can also be very effective for anxiety, and they can be a form of treatment themselves for social phobias. Stress management, relaxation techniques, and meditation all help reduce feelings of anxiety or of being out of control. Finally, having a strong support network of family and friends is an excellent way to help manage the difficulties of life with anxiety.

Asthma

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)

Treatment for most asthma patients involves three steps. Patients learn what their asthma triggers are and avoid them. They take a daily control medication, usually an inhaled corticosteroid, to reduce inflammation in the lungs. Also, they have rescue medication with them at all times to take in case of a severe attack. These quick-acting inhaled medications relax the muscles around the airways and allow the lungs to open up for air.

There is no cure for asthma, but with treatment it should not interfere with daily life and activities.
