Some issues Dr. John Carleton Nelson, 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.

Autoimmune Diseases

An autoimmune disorder happens when the immune system mistakenly attacks the tissues of its own body, causing symptoms of illness. There are more than 80 different types of autoimmune disorders. While some are very rare, others are fairly common. Combined, autoimmune disorders are one of the leading causes of death and disability in the United States, affecting approximately 24 million people.

A properly working immune system identifies foreign substances in the body that might cause illness, such as bacteria and viruses. The immune system then creates antibodies which attack the foreign substances, neutralizing them and keeping the body safe. In people with autoimmune disorders, something goes wrong with this process. For reasons that are not fully understand, the immune system creates antibodies to attack the patient's own tissues.

Symptoms of an autoimmune disorder depend on which tissue is being attacked by the immune system, but common symptoms of autoimmune disease include fever, fatigue, and a general feeling of just not being well. Autoimmune disorders are more common in women than in men, and they may run in families. Autoimmune disorders can affect various parts of the body such as blood vessels, connective tissue, endocrine glands, joints, muscles, red blood cells, skin, and many others.

It is common to have more than one autoimmune disorder at a time. Most are chronic, or life-long illnesses, although they may come and go in flares. Treatment for autoimmune disorders depends on which part of the body is being attacked. For example:

A type 1 diabetic whose pancreas has been damaged will need insulin.
A person with Hashimoto's whose thyroid has been damaged will need replacement thyroid hormones.
Someone with Sjogren's syndrome will need eye drops and mouth rinses to replace tears and saliva.

Many autoimmune disorders of all kinds are treated with immune-suppressing medications, such as corticosteroids (e.g. prednisone) to reduce the effect of the immune system.

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.
