Conditions & Treatments
An abdominal aortic aneurysm, also called AAA or triple A, is a bulging, weakened area in the wall of the aorta (the largest artery in the body) resulting in an abnormal widening or ballooning greater than 50 percent of the normal diameter (width).
Acne is a disorder of the hair follicles and sebaceous glands. The glands become clogged, leading to pimples and cysts.
Acoustic neurinoma, also referred to as acoustic neuroma or vestibular schwannoma, is a non-cancerous tumor that may develop from an overproduction of Schwann cells that press on the hearing and balance nerves in the inner ear.
Acromegaly is a disorder of the pituitary gland which produces excess growth hormones and thus results in excessive growth, first in the hands and feet, as soft tissue begins to swell.
Actinic keratosis, also known as a solar keratosis, is a scaly or crusty bump that arises on the skin surface.
Bronchitis is an inflammation of the breathing tubes (airways) that are called bronchi, which causes increased production of mucus and other changes.
Acute lymphocytic leukemia (ALL) is a cancer of the blood in which too many lymphocytes, a type of white blood cell, are produced by the bone marrow and by organs of the lymph system
Acute myelogenous leukemia (AML) is a cancer of the blood in which too many granulocytes, a type of white blood cell, are produced in the bone marrow.
Acute spinal cord injury (SCI) is a traumatic injury that either results in a bruise (also called a contusion), a partial tear, or a complete tear (called a transection) in the spinal cord.
An adjustment disorder is defined as an emotional or behavioral reaction to an identifiable stressful event or change in a person's life that is considered maladaptive or somehow not an expected, healthy response to the event or change.
Tumors of the adrenal glands can cause many problems by excess secretion of certain adrenal-produced hormones, most often resulting in high blood pressure, which can be extreme.
African trypanosomiasis is a disease carried by the tsetse fly. There are two types of the disease: West African trypanosomiasis causes a chronic infection lasting years, and East African trypanosomiasis causes acute illness lasting several weeks.
Alcohol-induced liver disease, as the name implies, is caused by excessive consumption of alcohol and is a common, but preventable, disease.
Hepatitis is the inflammation of the liver, resulting in liver cell damage and destruction. Alcoholic hepatitis is a complex problem and is a precursor to chronic liver disease and cirrhosis.
Rhinitis is a reaction that occurs in the nose when airborne irritants (allergens) trigger the release of histamine. Histamine causes inflammation and fluid production in the fragile linings of nasal passages, sinuses, and eyelids.
Allergies are among the most common heath problems, with more than 50 million people afflicted with asthma, seasonal hay fever, or other allergy-related conditions each year.
halassemia is an inherited disorder that affects the production of normal hemoglobin (a type of protein in red blood cells that carries oxygen to the tissues of the body).
Alzheimer's disease is a progressive, neurodegenerative disease that occurs when nerve cells in the brain die, often resulting in symptoms such as impaired memory, thinking and behavior.
Amenorrhea is a menstrual condition characterized by absent menstrual periods for more than three monthly menstrual cycles.
Amyotrophic lateral sclerosis (ALS) is a terminal neurological disorder characterized by progressive degeneration of nerve cells in the spinal cord and brain.
Analgesic nephropathy is a chronic kidney disease that gradually leads to end-stage renal disease and the need for permanent dialysis or a kidney transplant.
Folate deficiency is the lack of folic acid (one of the B vitamins) in the blood, which can cause a type of anemia known as megaloblastic (pernicious) anemia.
There are many types of anemias that require clinical care by a physician or other healthcare professional. Listed in the directory below are some, for which we have provided a brief overview.
An aneurysm is a bulging, weakened area in the wall of a blood vessel resulting in an abnormal widening or ballooning greater than 50 percent of the normal diameter
Angina pectoris (or simply angina) is recurring chest pain or discomfort that happens when some part of the heart does not receive enough blood and oxygen.
Ankylosing spondylitis (AS) is a type of arthritis that affects the spine.
Anorectal malformations are birth defects. With this defect, the anus and rectum do not develop properly.
Aortic stenosis is a narrowing of the opening of the heart’s aortic valve, which obstructs blood flow from the heart to the rest of the body.
Aphasia is a language disorder caused by damage in a specific area of the brain that controls language expression and comprehension, and leaves a person unable to communicate effectively with others.
Aplastic anemia occurs when the bone marrow produces too few red blood cells, white blood cells and platelets, making the patient susceptible to infection and making it more difficult for blood to clot.
Appendicitis is an inflammation of the appendix, a finger-like portion of the large intestine that generally hangs down from the lower right side of the abdomen.
Arrhythmias are heart rhythm disorders that may originate in the atria (the receiving chambers of the heart) or the ventricles (the pumping chambers of the heart).
Arthritis and other rheumatic diseases are characterized by pain, swelling, and limited movement in joints and connective tissues in the body.
Asthma is a chronic, inflammatory disease in which the airways become sensitive to allergens (any substance that triggers an allergic reaction).
Approximately 6.5 million children have been diagnosed with asthma according to the Centers for Disease Control and Prevention (CDC). Asthma is one of the most common, serious, chronic diseases among children, accounting for 14 million absences from school each year.
Ataxia causes a failure of muscle control in the arms and legs which may result in a lack of balance, coordination and possibly a disturbance in gait.
Ataxia telangiectasia is a rare childhood disease that affects the nervous system and some other body systems.
Atherosclerosis is a thickening or hardening of the arteries caused by a build-up of plaque in the inner lining of an artery.
Atopic dermatitis, also called eczema, is a hereditary and chronic skin disorder that causes a person’s skin to itch, turn red and flake. It mostly affects infants or very young children.
Atrial fibrillation is a type of arrhythmia where the electrical signals in the atria (the two small chambers of the heart) are fired in a very fast and uncontrolled manner.
ADHD, also called attention-deficit disorder, is a behavior disorder, usually first diagnosed in childhood, that is characterized by inattention, impulsivity, and, in some cases, hyperactivity.
Autism spectrum disorder is a neurological and developmental disorder that usually appears during the first three years of life.
Hepatitis is the inflammation of the liver, resulting in liver cell damage and destruction. In autoimmune hepatitis, the body's own immune system destroys liver cells.
Avascular necrosis is a disease that may cause bone or joint collapse as a result of loss of blood supply to the bone due to injury or other causes (such as long-term use of certain medications).
