Some issues Dr. Guillermo Lazo-Diaz, 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.

Hemophilia

Hemophilia is a bleeding disorder in which blood cannot clot normally. After an injury, people who have hemophilia bleed longer because they lack certain blood proteins that are responsible for clotting, called clotting factors. Some hemophiliacs are mildly deficient in this protein, so they bleed only when injured or after surgery. Those who are severely deficient, however, may experience symptoms of spontaneous bleeding, including the following:

Presence of blood in stool or urine
Frequent nosebleeds or large bruises
Unusual bleeding after being vaccinated
Pain, swelling, or tightness in joint

Most people with hemophilia have a family history of the disorder, though about 30% do not. The most common forms are hemophilia A (classic hemophilia) and hemophilia B (Christmas disease). Hemophilia A and B share certain characteristics, but different genes are involved. Acquired hemophilia is very rare and has been linked to autoimmune conditions, cancer, and multiple sclerosis.

Hemophilia may be diagnosed using a blood test. If there is family history of the disorder, testing may be done prenatally. Treatment involves regular intravenous replacement of clotting factors, which may be produced in a laboratory (recombinant) or come from blood donors. For people with milder forms of the disease, a hormone called desmopressin may stimulate the body to produce clotting factors. Other drug therapies include medications that help slow the breakdown of blood clots and medications that are applied directly to the wound to promote clotting.

Living with hemophilia can be challenging, but simple things may help prevent excessive bleeding. For example, choosing activities like walking or swimming over contact sports can prevent injuries and strengthen muscles while protecting the joints. Chances for bleeding may also be reduced by making sure that children wear helmets and elbow pads during activities like bicycle rides.
