During pregnancy glucose tolerance in the mother is affected. Glucose tolerance in pregnancy, as in the non-pregnant state is a continuum, represented by a distribution curve shifted to the right, with no clear divide between normal and abnormal. Many of the problems associated with overt diabetic pregnancies can be seen in infants of GDM pregnancies, such as macrosomia, neural tube defects, neonatal hypocalcemia, birth trauma and subsequent childhood and adolescent obesity. Impaired glucose intolerance (IGT) in pregnancy is also a major risk factor for the development of NIDDM (non-insulin dependent diabetes mellitus) and IGT in later life and is associated with not only an increased risk for coronary heart disease (CHD) disease but also many other morbidities and mortalities associated with overt diabetes. The problem remaining to be resolved is the precise level of glucose intolerance in pregnancy that poses a significant risk for the later health of the mother. Nor is increased gestational glucose intolerance the only reproductive event that has been linked with future NIDDM risk. Other factors have been known to predispose pregnant women to the risk of future diabetes (e.g. BMI, age and weight change). The findings of the present study suggest that the association of glucose intolerance during pregnancy, with the subsequent incidence of diabetes and certain co-morbidities in the mother, is continuous throughout the range of glucose concentrations studied. The risk of future diabetes is also affected by certain maternal characteristics (BMI at index pregnancy and at follow-up, weight change).

Diabetes mellitus belongs to diseases frequently occurring in childhood and adulthood. Insufficient knowledge of this disease and an unsatisfactory compensation for diabetes leads to development of late complications that have a negative impact on one's, as well as the family's, life and create an economic problem for society as a whole. The thesis focuses on the main characteristics of the disease, symptoms, diagnosis and treatment. Complications of the disease, including advice for patients themselves and their prevention are described in more detail. Social aspects (work inclusion of a diabetic, invalidity and reduced work capacity, driving of motor vehicles) are also emphasised. The research part containing 18 questions aims to find out to what extent the Czech public is informed about the problematic areas of this disease. It also assesses the feasibility of obtaining information from individuals of different ages and places of residence (city vs. village) regarding diabetes. These hypotheses were stated within the scope of the research: 1. Individuals older than 50 years of age are better informed about diabetes than individuals of a younger age. 1. Individuals living in a city have a better access to information concerning diabetes than individuals living in a village. The data was obtained from questionnaire research, in which respondents older than 18 years of age participated. The data collection took place in Bechyně Spa Ltd. 58 % of the resultant questionnaires were completed by women and 42 % by men.

It is currently accepted that the most appropriate diet in the treatment of non-insulin-dependent diabetes mellitus &quoteNIDDM&quote is high in carbohydrates, high in fibre and low in fat. Dietary fibre reduces the rate of carbohydrate absorption, which may have a beneficial effect on insulin action. Furthermore, high fibre diets also increase the amount of carbohydrates which are not absorbed from the small intestine. These malabsorbed carbohydrates are fermented by the bacterial population in the large intestine, producing short chain fatty acids &quoteSCFA&quote, including propionate, which has been shown to alter liver carbohydrate metabolism. This thesis investigated the actions of slowed carbohydrate absorption and carbohydrate malabsorption in streptozotocin-induced &quoteSTZ&quote diabetic rats. High carbohydrate diet supplemented with guar gum, a soluble dietary fibre, fed to STZ diabetic rats improved insulin sensitivity. investigation of the alterations in the stomach and small intestine demonstrated that guar increased the viscosity of the meal in the intestine. The action of increased fermentation, producing more propionate, was investigated by supplementing propionate into the diets of STZ diabetic rats or when perfused into isolated rat livers. No changes in insulin action or liver glucose metabolism were measured. in addition, it was shown that guar gum reduces food intake in STZ diabetic rats. Mild reductions in food intake in STZ diabetic rats were shown to increase insulin action. In summary, STZ diabetic rats fed high carbohydrate, high fibre diets reductions in food consumption and slowed carbohydrate absorption are important factors which may lower blood glucose concentrations and increase insulin action. increased SCFA production is unlikely to contribute significantly to the improvements in insulin action.

Intermittent fasting (IF) is a recently popularized meal timing strategy whereby individuals abstain continuously from any energy intake for 16 to 20 hours each day, subsequently condensing energy intake into a short period spanning 4 to 8 hours. We aimed to test the effects of intermittent fasting in 10 individuals with Type 2 Diabetes Mellitus in conjunction with recommendations to consume a high protein diet in a 6 to 8 week withdrawal study. This study consisted of three phases: baseline, intervention, and follow-up. During the 2-week baseline and intervention phases participants consumed meals at regular times. Biochemical, anthropometric, and physical activity measurements were taken at the end of each phase. Participants reported morning, afternoon and evening self-monitored blood glucose and fasting duration on a daily basis, in addition to completing a remote food photography diary three times within each study phase. Despite the short duration of the intervention phase, intermittent fasting led to significant decreases in weight, BMI, morning SMBG, and overall reductions in waist circumference, C-reactive protein, energy intake, carbohydrate intake, and fat intake. There were significant variations between participants in response to intermittent fasting in respect to changes in lipids and insulin sensitivity, which could not be explained by baseline biochemical or anthropometric measures, fasting duration, energy intake, or physical activity. Upon cessation of intermittent fasting, biochemical changes regressed towards baseline values during the follow-up period. Intermittent fasting was well tolerated by most participants, and no severe adverse events were noted. Morning nausea was the most common complaint, which abruptly ceased when medication timing was changed.
