Dizziness, anxiety as a cause ofOne 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).
RELATED TERMS--------------------------------------
Dizziness
Painless 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.
Anxiety
A psychological and/or biological response to stress. Feelings of anxiety involve discomforting apprehension or concern, which may include symptoms such as cognitive difficulties, hypersensitivity, dizziness, muscular weakness, breathing difficulties, irregular heart beat, sweating, and sensations of fear. Typically, anxiety is a natural and healthy response to life experiences. However, exaggerated or chronic anxiety often indicates an anxiety disorder. Anxiety can be produced by external stress (exogenous anxiety) or internal stress (endogenous anxiety).
Breathing
The process of respiration, during which air is inhaled into the lungs through the mouth or nose due to muscle contraction, and then exhaled due to muscle relaxation.

Dizziness is a medically indistinct term which laypersons use to describe a variety of conditions ranging from lightheadedness, unsteadiness to vertigo.
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.

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.

Painless 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.

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.
DM1
Type 1 myotonic dystrophy.
