| gestational diabetes | A glucose intolerance which occurs in pregnancy, usually noticed between the 24th and 28th weeks of pregnancy. In most cases the blood glucose level returns to normal after delivery. Although the symptoms of this form of diabetes are mild and nonserious for the mother, elevated blood glucose in the mother has been associated with an increased risk of foetal and newborn death. Risk factors for gestational diabetes include maternal age over 25, family history of diabetes, obesity, birth weight over 9 lb in a previous delivery or a history for congenital birth defect or death, in a previous newborn. (27 Sep 1997) |
| gestational oedema | Occurrence of a generalised and excessive accumulation of fluid in the tissues of greater than 1+ pitting after 12 hours' bed rest, or of a weight gain of 5 pounds or more in 1 week due to the influence of pregnancy. (05 Mar 2000) |
| gestational proteinuria | The presence of proteinuria during or under the influence of pregnancy in the absence of hypertension, oedema, renal infection, or known intrinsic renovascular disease. (05 Mar 2000) |

| small for gestational age | <obstetrics, paediatrics> A weight classification of newborns associated with poor health outcomes, the weight falling below the 10th percentile on the intrauterine growth curve for the infant's calculated gestational age. (27 Sep 1997) |
| diabetes, gestational | A diabetic condition that appears during pregnancy (gestation) and may go away after the birth of the baby. (12 Dec 1998) |
| infant, small for gestational age | An infant having a birth weight lower than expected for its gestational age. (12 Dec 1998) |

| air sac | <zoology> Thin-walled sacs or spaces which function as a part of the respiratory system in birds, fishes, insects, and mammals. The sacs are filled with air and connected with the air passages of the lungs; an air cell. Source: Websters Dictionary (04 Jul 1999) |
| allantoic sac | The dilated distal portion of the allantois; it forms part of the placenta in many mammals. (05 Mar 2000) |
| alveolar sac | Terminal dilation of the alveolar ducts that give rise to alveoli in the lung; a small air chamber in the pulmonary tissue from which the pulmonary alveoli project like bays and into which an alveolar duct opens; in birds, air-containing extensions of bronchi that connect with bone cavities. Synonym: sacculus alveolaris, air sac. (05 Mar 2000) |
| amniotic sac | <anatomy, obstetrics> Sac, enclosing the embryo of amniote vertebrates, that provides a fluid environment to prevent dehydration during development of land based animals. See: amnion. (18 Nov 1997) |
| anal sac | A vesicular cutaneous invagination opening by a duct on each side of the anal canal in carnivores (best developed in skunks, but absent in some bears, the raccoon, kinkajou, coati, and sea otter), each lying between the external and internal anal sphincter muscles, which aid in emptying the contents. The sac stores odouriferous scent markers produced by glands that line its wall or duct; frequently the sac becomes impacted in the dog or cat, requiring manual emptying. (05 Mar 2000) |
