The step lengthens as the pregnancy progresses, due to weight gain and changes in posture. On average, a woman's foot can grow by a half size or more during pregnancy. In addition, the increased body weight of pregnancy, fluid retention, and weight gain lowers the arches of the foot, further adding to the foot's length and width.
In maternal diabetes, 90% of pregnancy losses happen in the first trimester due to oxidative stress. Diabetic embryopathy abortions in the second-trimester are most likely due to severe birth defect , maternal metabolic derangement, placental insufficiency and fetal hypoxia due to membrane rupture.
A previous diagnosis of gestational diabetes or prediabetes, impaired glucose tolerance, or impaired fasting glycaemia; A family history revealing a first-degree relative with type 2 diabetes; Maternal age – a woman's risk factor increases as she gets older (especially for women over 35 years of age).
Pre-gestational diabetes can be classified as Type 1 or Type 2 depending on the physiological mechanism. Type 1 diabetes mellitus is an autoimmune disorder leading to destruction of insulin-producing cell in the pancreas; type 2 diabetes mellitus is associated with obesity and results from a combination of insulin resistance and insufficient insulin production.
Dysglycemia is a general definition for any abnormalities in blood glucose levels. They include hyperglycemia, hypoglycemia, impaired glucose tolerance test, impaired fasting glucose, among others. [1] [2] [3] [4]
In people with impaired glucose tolerance or impaired fasting glucose, presence of metabolic syndrome doubles the risk of developing type 2 diabetes. [37] It is likely that prediabetes and metabolic syndrome denote the same disorder, defining it by the different sets of biological markers.
Obesity has been found to contribute to approximately 55% of cases of type 2 diabetes; [10] chronic obesity leads to increased insulin resistance that can develop into type 2 diabetes, [11] most likely because adipose tissue (especially that in the abdomen around internal organs) is a source of several chemical signals, hormones and cytokines, to other tissues.
The glucose tolerance test was first described in 1923 by Jerome W. Conn. [4]The test was based on the previous work in 1913 by A. T. B. Jacobson in determining that carbohydrate ingestion results in blood glucose fluctuations, [5] and the premise (named the Staub-Traugott Phenomenon after its first observers H. Staub in 1921 and K. Traugott in 1922) that a normal patient fed glucose will ...
