Anemia is a lower than normal number of red blood cells (erythrocytes) in the blood, usually measured by a decrease in the amount of hemoglobin. Hemoglobin is the red pigment in red blood cells that transports oxygen. There are many types and potential causes of anemia. For information about a specific type of anemia, see one of the following articles: Anemia - B12 deficiency Anemia - folate deficiency Anemia - iron deficiency Anemia due to chronic disease Hemolytic anemia Hemolytic anemia - G-6-PD deficiency Idiopathic aplastic anemia Idiopathic autoimmune hemolytic anemia Immune hemolytic anemia Immune hemolytic anemia - drug-induced Megaloblastic anemia Pernicious anemia Secondary aplastic anemia Sickle cell anemia

Anemia is a condition characterized by abnormally low levels of healthy red blood cells or hemoglobin. The tissues of the human body need a regular supply of oxygen to stay healthy.
|
|
Anemia is characterized by an abnormally low number of red blood cells in the circulating blood. It frequently affects patients with cancer.

A spontaneous abortion is the loss of a fetus during pregnancy due to natural causes. The term "miscarriage" is the spontaneous termination of a pregnancy before fetal development has reached 20 weeks. Pregnancy losses after the 20th week are categorized as preterm deliveries. The term "spontaneous abortion" refers to naturally occurring events, not elective or therapeutic abortion procedures. Other terms include: missed abortion (a pregnancy demise where nothing is expelled) incomplete abortion (not all of the products of conception are expelled) complete abortion (all of the products of conception are expelled) threatened abortion (symptoms indicate a miscarriage is possible) inevitable abortion (the symptoms cannot be stopped, and a miscarriage will happen) infected abortion
|
|
Miscarriage is common, but finding its cause may not be easy. If a cause can be found, it’s likely to be a problem with the baby or the structure of the uterus.
|
|
A miscarriage is the loss of an embryo or fetus before the twentieth week of pregnancy . A pregnancy loss after the twentieth week is called a stillbirth.
|
|
Miscarriage means loss of an embryo or fetus before the 20th week of pregnancy . Most miscarriages occur during the first 14 weeks of pregnancy.

Osteoporosis is the thinning of bone tissue and loss of bone density over time.
|
|
|
Osteoporosis , which is characterized by a decrease in the mass of otherwise normal bone is the most common metabolic bone disease. Normal bone is made of a hard outer shell (the cortex) and an inner network of spicules (fibers), called trabeculae, that give bone its characteristic strength.
|
|
Osteoporosis (literally " porous bone " ) is a condition characterized by bone fragility and fracturing. The World Health Organization (WHO) defines osteoporosis as a 25 percent reduction of bone mineral density (BMD) compared to that of a healthy young adult female.
|
|
|
The word osteoporosis literally means " porous bones. " It occurs when bones lose an excessive amount of their protein and mineral content, particularly calcium .

A variety of exercises is best. Physical activity will slow further bone loss. It can also be fun.
|
|
|
Osteoporosis is a disease characterized by low bone mass and deterioration of bone tissues, leading to bone fragility and, consequently, an increase in fracture risk. The term osteoporosis comes from the Greek word osteon , meaning bone, and porus , meaning pore or passage.

Your body needs calcium to build and repair bones. But it can't make calcium on its own. That's why it's important to eat calcium-rich foods. Some foods are naturally rich in calcium. Others have calcium added.
|
|
|
Depending on your needs, your provider may prescribe more than one medication to prevent or treat osteoporosis.
|
|
|
Bone density testing is safe, quick, easy, and painless. Testing can detect osteoporosis before a fracture happens. It can also predict the risk of future fractures. And testing can measure the response to treatment.
|
|
|
Certain factors can speed up bone loss or decrease bone growth. For example, alcohol, cigarettes, and certain medicines reduce bone mass. Some foods make it hard for your body to absorb calcium.
|
|
|
The body is always making and losing (resorbing) bone. This process is called remodeling. Bone-making cells form new bone using calcium and other minerals. These minerals come from the food you eat.
|
|
|
Exercise plays a big part in maintaining bone mass no matter what your age. The amount and type of activity you do also play a part in keeping your bones strong.

The thyroid gland is located in the base of the neck on both sides of the lower part of the larynx (voice box) and upper part of the trachea (wind pipe). The gland produces thyroid hormone in response to stimulation by a hormone from the pituitary gland. Thyroid hormone acts throughout the body to regulate metabolism. Thyroid diseases can be broadly divided into the following categories: Overproduction of thyroid hormone (hyperthyroidism) Underproduction of thyroid hormone (hypothyroidism) Benign (noncancerous) thyroid disease Thyroid cancer For information about a specific type of thyroid disease see one of the following: Anaplastic carcinoma of the thyroid Chronic thyroiditis (Hashimoto's disease) Colloid nodular goiter Hyperthyroidism Hypopituitarism Hypothyroidism Hypothyroidism - primary Hypothyroidism - secondary Medullary thyroid carcinoma Painless (silent) thyroiditis Papillary carcinoma of the thyroid Subacute thyroiditis Thyroid cancer Congenital goiter
|
|
Thyroid disorders fall into two general categories:(1) dysfunction of thyroid hormone production; and (2) development of thyroid enlargements, called goiters, which include generalized enlargement of the gland and benign and malignant nodules. Thyroid dysfunction results either from increased or decreased secretion of thyroid hormones, called hyperthyroidism or hypothyroidism, respectively.
