Some issues Dr. Siamak Marzbani, MD can help you with:

Anemia

Anemia is the most common blood disorder. It occurs when the body does not have enough red blood cells to carry oxygen to the tissues. Blood loss, insufficient red blood cell production, and red blood cell destruction are the three main causes of anemia. These issues may arise from such conditions as iron deficiency, heavy periods, ulcers, kidney disease, as well as some forms of cancer.

An individual with anemia will have the following symptoms: shortness of breath, weakness, dizziness, cold hands or feet, paleness, and irritability. Anemia is diagnosed when blood tests show low counts for hemoglobin, which is the protein responsible for carrying oxygen to different tissues throughout the body.

Treatments for anemia are dependent on the kind of anemia an individual has. For example, iron supplementation may correct iron deficiency anemia. For anemia caused by chronic kidney failure, chemotherapy treatments, and HIV/AIDS, a group of medications called erythropoiesis-stimulating agents may be prescribed.

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.

Stress Urinary Incontinence

Stress urinary incontinence is a disorder in which the bladder leaks urine during activities that require exertion, such as lifting, laughing, coughing, and sneezing. Leakage occurs because the muscles responsible for holding urine have become weak. This type of incontinence will affect about one in three women at some point in their lives. It is particularly prevalent in women who have given birth vaginally, have been pregnant, are extremely overweight, or are in menopause. Although more women than men suffer from stress incontinence, men who have had prostate surgery are also at risk of developing this condition.

Treatments vary based on the severity of the incontinence. Mild to moderate leakage may be controlled by doing pelvic floor exercises, avoiding foods that can irritate the bladder, or taking medication. For severe incontinence, however, surgery may be necessary. The most common procedures for stress urinary incontinence are bladder suspension, artificial urinary sphincter surgery, and sling surgery.

Each of these procedures takes about an hour to an hour and a half. Patients will likely wake up with a catheter, a tube that drains urine, as swelling after surgery makes it difficult to urinate. Taking slow, short walks to keep the blood flow moving is usually encouraged within hours of the surgery. Although patients may return to work within seven to ten days after certain procedures, strenuous activities such as running and working out are not recommended for at least four to six weeks. In addition, patients should avoid lifting objects over 15 pounds for three months after any of these operations.
