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).
PREVIOUS AND NEXT TERMS--------------------------------------
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.

Dizziness, pre-syncopal
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.
DM2
Myotonic dystrophy type 2.
