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 characterized by an abnormally low number of red blood cells in the circulating blood. It frequently affects patients with cancer.
|
|
Anemia is a blood disorder characterized by abnormally low levels of healthy red blood cells (RBCs) or reduced hemoglobin (Hgb), the iron-bearing protein in red blood cells that delivers oxygen to tissues throughout the body. Reduced blood cell volume (hematocrit) is also considered anemia.

|
Dizziness is a general term that describes sensations of imbalance and unsteadiness, such as vertigo, mild turning, imbalance, and near fainting or fainting. Feelings of dizziness stem from the vestibular system, which includes the brain and the parts of the inner ear that sense position and motion, coupled with sensory information from the eyes, skin, and muscle tension.
|
|
When the brain receives conflicting signals, or when there is a problem with blood flow, dizziness or fainting can occur.

Falls or accidents can lead to pain, broken bones, and fear of future falls. Protect yourself and others by preparing for episodes. Simple steps can help increase your safety at home and wherever you go.

Can arthritis in neck and shoulders be the cause of "positional vertigo?" In the past, when I've experienced vertigo symptoms I've visited my chiropractor for an adjustment that would successfully relieve my misalignment, which was pinching a nerve in my neck and causing the dizziness. My last episode was not as successful, though.

Drowsiness refers to feeling abnormally sleepy during the day -- often with a strong tendency to actually fall asleep in inappropriate situations or at inappropriate times.
|
|
Each year, at least 100,000 vehicular crashes and 1,550 deaths are caused by drivers who are impaired by sleepiness.
|
|
When drowsiness occurs most of the time or causes a person to fall asleep at inappropriate times, quality of life and performance can be affected.

Hypersomnia refers to a set of related disorders that involve excessive daytime sleepiness. There are two main categories of hypersomnia: primary hypersomnia (sometimes called idiopathic hypersomnia) and recurrent hypersomnia (sometimes called recurrent primary hypersomnia).

The heart rate, usually measured by checking the arterial pulse or sounds counting the
times of the heart beat, is considered one of the vital signs. Vital signs - body
temperature, pulse, breathing rate, and blood pressure provide information about the state
of health of a person and, if abnormal, offer clues to problems.

Unconsciousness is when a person is unable to respond to people and other stimuli around him or her. Often, this is called a coma or being in a comatose state. Other changes in awareness can occur without becoming unconscious. Medically, these are called "Altered Mental Status" or "Changed Mental Status." They include sudden confusion, disorientation, or stupor. Unconsciousness and any other SUDDEN change in mental status must be treated as a medical emergency. If someone is awake but less alert than usual, ask a few simple questions -- What is your name? What is the date? How old are you? If the person doesn't know or answers incorrectly, then his or her mental status is diminished.

Low blood pressure, or hypotension, occurs when blood pressure during and after each heart beat is much lower than usual. This means the heart, brain, and other parts of the body do not get enough blood. Dizziness or lightheadedness can result. See also: Blood pressure
|
|
Hypotension is the medical term for low blood pressure. The pressure of the blood in the arteries rises and falls as the heart and muscles handle demands of daily living, such as exercise , sleep and stress .
|
|
Doctors often consider chronically low blood pressure too low only if it drops suddenly or causes noticeable symptoms.
|
|
While recommended healthy blood pressure levels have decreased, lowering diastolic pressure too much could deprive the heart of needed blood flow, which could be dangerous for people with coronary artery disease.
|

Preliminary studies show that a promising new drug may treat the symptoms of low blood pressure.

Numbness and tingling are abnormal sensations that can occur anywhere in your body, but are often felt in your hands, feet, arms, or legs.
|
|
Numbness and tingling are decreased or abnormal sensations caused by altered sensory nerve function. The feeling of having a foot " fall asleep " is a familiar one.
|
|
The most common reason for numbness or tingling is a problem with nerve function, either because the nerve itself is injured, something is pressing on the nerve, or an imbalance in the body's chemistry interferes with nerve function.
