Dilated cardiomyopathy
A disease of the myocardium (heart muscle) that causes the heart cavity to become stretched and enlarged, and the pumping capacity of the heart is reduced.
Dilated Pupil Examination
A necessary part of an examination for diabetic eye disease. Special drops are used to enlarge the pupils, enabling the doctor to view the back of the eye for damage.
Dilating
The widening and opening of the cervix caused by uterine contractions.
Dilation
The opening of the cervix during labor.
Dilation and Curettage (D and C)
Surgical procedure in which the cervix is dilated (widened) and the endometrium (lining of the uterus) is scraped away.
Dilation, pupil
This examination enables your eye care professional to see more of your retina, the light-sensitive layer of tissue at the back of your eye. Dilating (widening) the pupil permits your eye to be examined for signs of disease. To do this, drops are placed into the eye to dilate (widen) the pupil. After the examination, your vision may (or may not) remain blurred for several hours.
Dilation, pupil (test)
This examination enables your eye care professional to see more of your retina, the light-sensitive layer of tissue at the back of your eye. Dilating (widening) the pupil permits the retina to be examined for signs of disease. To do this, drops are placed into the eye to dilate (widen) the pupil. After the examination, your vision may (or may not) remain blurred and you may (or may not) be bothered by the brightness of the sun for several hours. The pupil, the opening of the iris, may appear to open (dilate) and close (constrict) but it is really the iris that is the prime mover; the pupil is merely the absence of iris. The pupil determines how much light is let into the eye.
Dilator
A device used to stretch or enlarge an opening. Patients with scarring of the muscular tube through which food passes from the throat to the stomach (esophagus) can require a dilator procedure in order to open the esophagus for adequate passage of food and fluids.
Dilatrate-sr
Dilatrate-sr is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): isosorbide dinitrate.

Diastolic Pressure
The pressure of the blood in the arteries when the heart is filling. It is the lower of two blood pressure measurements, e.g., 120/80, where 80 is the diastolic pressure.
Diastolic
The lower number in a blood pressure reading that indicates the pressure in the heart when the muscle is relaxed (the point of least pressure).
Dilated cardiomyopathy
A disease of the myocardium (heart muscle) that causes the heart cavity to become stretched and enlarged, and the pumping capacity of the heart is reduced.
Dilatation
DNR Order (Do Not Resuscitate Order)

Donor
A person who gives an organ, tissue or blood to another person. A compatible donor is a person who has the same tissue and blood types as the person who receives the organ, tissue or blood.
D-dimer
A fragment produced during the degradation of a clot. The D here stands for domain. Dimer indicates two identical units, in this case two identical domains. D-dimer result from complete breakdown of the clot. Monoclonal antibody to the D-dimer fragment provide the basis for the main methods of detecting it. The presence of D-dimers in the blood is a reliable clue that clotting has begun. Sometimes written d-dimer or D-Dimer. Pronounced deemer.
D-IBS
Diarrhea-predominant IBS (irritable bowel syndrome).
