Dizziness
|
|
DizzinessPainless head discomfort with many possible causes including disturbances of vision, the brain, balance (vestibular) system of the inner ear, and gastrointestinal system. Dizziness is a medically indistinct term which laypersons use to describe a variety of conditions ranging from lightheadedness, unsteadiness to vertigo.
RELATED TERMS--------------------------------------
Vision
The sense of sight.
Brain
"That part of the central nervous system that is located within the cranium (skull). The brain functions as the primary receiver, organizer and distributor of information for the body. It has two (right and left) halves called ""hemispheres."" "
Balance
A biological system that enables us to know where our bodies are in the environment and to maintain a desired position. Normal balance depends on information from the inner ear, other senses (such as sight and touch) and muscle movement.
Ear
The hearing organ. There are three sections of the ear, according to the anatomy textbooks. They are the outer ear (the part we see along the sides of our head behind the temples), the middle ear, and the inner ear. But in terms of function, the ear has four parts: those three and the brain. Hearing thus involves all parts of the ear as well as the auditory cortex of the brain. The external ear helps concentrate the vibrations of air on the ear drum and make it vibrate. These vibrations are transmitted by a chain of little bones in the middle ear to the inner ear. There they stimulate the fibers of the auditory nerve to transmit impulses to the brain.
Gastrointestinal
Having to do with the stomach and intestines.

Vertigo
Dizziness.
SIMILAR TERMS--------------------------------------
Dizziness, anxiety as a cause of
One cause of dizziness is overbreathing (hyperventilation) due to anxiety. The overbreathing also causes lightheadedness, a sense of unsteadiness and tingling around the mouth and fingertips. Relief can be gotten by breathing in and out of a paper bag (to increase the level of carbon dioxide in the blood).
Dizziness, pre-syncopal
Dizziness before fainting. Some symptoms of dizziness such as wooziness, feeling about to black out, and tunnel vision may be pre-syncopal and are due to insufficient blood flow to the brain. These symptoms are typically worse when standing, improve with lying down and may be experienced by healthy individuals who rise quickly from a chair, often after a meal, and have a few seconds of disorientation.
PREVIOUS AND NEXT TERMS--------------------------------------
Diverticulitis, bleeding from
Diverticular bleeding typically occurs intermittently over several days. Colonoscopy is usually performed to confirm the diagnosis and exclude bleeding from other causes. Thermal probes cannot be employed to stop active diverticular bleeding. Therefore, surgical removal of the bleeding diverticula is necessary for those with persistent bleeding.
Diverticulitis, treatment of acute
Antibiotics are usually needed. Oral antibiotics are sufficient when symptoms are mild. Liquid or low fiber foods are advised during acute diverticulitis attacks. In severe diverticulitis with high fever and pain, patients are hospitalized and given intravenous antibiotics. Surgery is needed for persistent bowel obstruction or abscesses not responding to antibiotics.
Diverticulosis/diverticulitis and fiber
High fiber diets help delay the progression of diverticulosis and, at least, reduce the bouts of diverticulitis.
Diving injury
An injury incurred from diving into water that is too shallow or has hidden hazards. These injuries may be to the head, neck, or spinal cord. Many diving injuries result when persons --predominantly males aged 15-25 years -- plunge into swimming pools or natural bodies of water such as rivers, streams, lakes, and oceans. In one study, 15 cases of quadriplegia were reported. One resulted from a dive into a swimming pool; the other 14 cases resulted from dives into rivers, streams, lakes, or oceans. Only three of these injured persons had objective evidence of the depth of the water at the time of injury, Most of the divers had underestimated it.
Dizygotic twin
A twins who have shared a common uterine environment with its twin but is due to a different fertilized ovum. Dizygotic twins are also called fraternal twins.

DKK1
A gene that inhibits the activity of osteoblasts, the cells that build bone. DKK1 acts by inhibiting Wnt signaling, which is essential for the growth and development of osteoblasts. DKK1 is overexpressed in the plasma cells in multiple myeloma. The DKK1 produced by the myeloma cells tips the balance between osteoblasts and osteoclasts in favor of bone resorption. This contributes to the maintenance of the lytic ("punched-out") lesions in bone characteristic of multiple myeloma. DKK1 stands for Dickkopf1.
DLI
Donor lymphocyte infusion.
DM
Myotonic dystrophy.
