Some issues Dr. Yousef Khelfa, 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.
