Obesity is increasing in epidemic proportions world-wide. Even mild degrees of obesity have adverse health effects and are associated with diminished longevity. For this reason aggressive dietary intervention is recommended. Patients with body mass indices exceeding 40 have medically significant obesity in which the risk of serious health consequences is substantial, with concomitant significant reductions in life expectancy. For these patients, sustained weight loss rarely occurs with dietary intervention. For the appropriately selected patients, surgery is beneficial. Various operations have been proposed for the treatment of obesity, many of which proved to have serious complications precluding their efficacy. A National Institutes of Health Consensus Panel reviewed the indications and types of operations, concluding that the banded gastroplasty and gastric bypass were acceptable operations for treating seriously obese patients. Surgical treatment is associated with sustained weight loss for seriously obese patients who uniformly fail nonsurgical treatment. Following weight loss there is a high cure rate for diabetes and sleep apnea, with significant improvement in other complications of obesity such as hypertension and osteoarthritis.

Epidemiologic literature suggests that persons with clinically diagnosed sleep apnoea frequently have impaired cognitive function, but whether milder degrees of sleep-disordered breathing (SDB) are associated with cognitive dysfunction in the general population is largely unknown. Approximately 1700 subjects free of clinically diagnosed SDB underwent at-home polysomnography (PSG) as part of the Sleep Heart Health Study (SHHS) and completed three cognitive function tests within 1-2 years of their PSG: the Delayed Word Recall Test (DWR), the WAIS-R Digit Symbol Subtest (DSS), and the Word Fluency test (WF). A respiratory disturbance index (RDI) was calculated as the number of apnoeas and hypopnoeas per hour of sleep. After adjustment for age, education, occupation, field centre, diabetes, hypertension, body-mass index, use of CNS medications, and alcohol drinking status, there was no consistent association between the RDI and any of the three cognitive function measures. There was no evidence of a dose-response relation between the RDI and cognitive function scores and the adjusted mean scores by quartiles of RDI never differed from one another by more than 5% for any of the tests. In this sample of free-living individuals with mostly mild to moderate levels of SDB, the degree of SDB appeared to be unrelated to three measures of cognitive performance.

The diagnosis of Cushing's syndrome rests on the demonstration of clinical features and biochemical abnormalities that reflect hypercortisolism. If a patient presents with typical clinical features such as weight gain with truncal obesity and supraclavicular fat deposition, wide purple striae, and proximal muscle weakness, the diagnosis is clear-cut and is nearly always substantiated by a 24-hour urine free cortisol excretion value more than four times the normal level. However, many patients present with signs and symptoms that are common in the general population, such as hypertension, generalized weight gain, reproductive abnormalities, and depression. Many of these patients have normal cortisol excretion and do not have Cushing's syndrome. Others have mild hypercortisolism caused by psychiatric disorders, obligate exercise, morbid obesity, sleep apnea, or uncontrolled diabetes mellitus. These patients may be confused with those with the true Cushing's syndrome, and thus are considered to have a "pseudo-Cushing" state. Additional observation over time, and testing with midnight cortisol measurements, the 2-day-2-mg dexamethasone suppression test, or the dexamethasone suppression-CRH stimulation test may be useful to identify true Cushing's syndrome in these patients.

Obesity among adults has increased 60% since 1991, and 25% of children are overweight or obese. Direct and indirect costs of obesity represent almost 17% of total health care costs. People who are morbidly obese are far more likely to develop diabetes, hypertension, sleep apnea, osteoarthritis, and some forms of cancer, as well as depression and anxiety disorders than people who are not obese. Medical treatment of obesity only has long-term success rates of approximately 5%. Studies have validated that bariatric surgery, on the other hand, has greater success rates for weight loss maintenance. Of current surgical options, Roux-en-Y gastric bypass offers the best results:complications ratio and is seen as the "gold standard" in bariatric surgery.

Sleep and sleep disorders play a prominent role in hormone regulation. Given that sleep disordered breathing (SDB) and diabetes mellitus (DM) are thought to result from obesity, it has been assumed that when the two coexist, the diabetes was caused by the obesity. However, new data has shed light on the effects that SDB, sleep deprivation, and snoring have on glucose regulation. It now appears that in addition to causing daytime drowsiness, cardiovascular disease, mood and memory disturbances, impotence, and car wrecks, obstructive sleep apnea (OSA) also promotes insulin resistance. Though data is still sketchy on the optimum management of coexisting DM and OSA, large-scale studies will most likely prove that homeostatic glucose control in patients with sleep apnea will require aggressive treatment of their SDB.

Sleep disordered breathing (SDB) frequently comes to medical attention for the first time when patients are hospitalized for diagnosis and treatment of an associated condition (eg, poorly controlled hypertension, myocardial infarction, congestive heart failure, stroke, or problems related to management of diabetes mellitus). Diagnosis of SDB is generally performed in a specialized facility, which is often inconvenient and expensive for the hospitalized patient. Expectant perioperative management of patients with sleep apnea is critical, particularly if they are previously undiagnosed. An ideal diagnostic strategy for these patients has not been defined. Continuous positive airway pressure (CPAP) is the mainstay of treatment of patients with sleep apnea. Unfortunately, it is often difficult for very ill patients to tolerate CPAP, unless it is administered with a high level of expertise.

In the last 20 years, there has been a dramatic upsurge in the average weight of Australian adults. In this period, on average, Australian women have gained 4.8 kg, whilst Australian men have gained 3.6 kg. Consequently, the prevalence of obesity in men has increased from 8% to 19% and in women from 7% to 21%. This threatens to wipe away many recent health gains, as obesity has been associated with a wide range of chronic and debilitating illnesses, such as diabetes, heart disease, some cancers, sleep apnoea and osteoarthritis. Any weight gain in adulthood is usually as a result of an increase in fat stores, and the risk of ill-health from increasing weight actually begins at quite low BMI. Unfortunately, weight gain can be difficult or slow to reverse in the middle years because of physiological and behavioural changes that occur at this time of life. Adults should focus on preventing or minimizing weight gain over time by retaining physical activity within their daily living and by sensible dietary changes. Even if weight gain does occur with age, a regimen of regular exercise and a diet rich in fruit and vegetables and low in fat will provide some protection against a rapid decline in health.

The purpose of this article is to review the current state of knowledge on contributions of nocturnal urine overproduction and overactive bladder to the syndrome of nocturia. We review the recent literature and current state of the art in differential diagnosis, pathophysiology, and classification of nocturia. We found that multiple pathologic factors may result in nocturia, including cardiovascular disease, diabetes mellitus or insipidus, third spacing of fluid, sleep apnea, lower urinary tract obstruction, primary sleep disorders, and behavioral and environmental factors. Thus, nocturia may be attributed to nocturnal polyuria (nocturnal urine overproduction), diminished nocturnal bladder capacity, or both. Distinction between these conditions is made by a simple arithmetic analysis of the 24-hour voiding diary. Understanding the manifold origins of nocturia will lead to rational treatment of specific contributing pathophysiologic factors.

The relationships between obstructive sleep apnoea syndrome (OSAS) and stroke are still under discussion, but increasing evidence demonstrates that the OSAS is an independent risk factor for stroke. However, in rare cases, OSAS could be a consequence of strokes, especially if located in the brainstem. Many recent studies have found a 70 to 95% frequency of OSAS (defined by an apnoea/hypopnoea index >10) in patients with acute stroke. Age, body mass index, diabetes, and severity of stroke have been identified as independent predictors of stroke. Furthermore, the presence of OSAS in stroke patients could lead to a poor outcome. The potential mechanisms linking OSAS and stroke are probably multiple (arterial hypertension, cardiac arrhythmia, increased atherogenesis, coagulation disorders, and cerebral haemodynamic changes). Despite numerous uncertainties, OSAS should be systematically screened at the moment it is clinically suspected in patients with acute stroke. However, the optimal timing (early or differed) for treatment with nasal continuous positive airway pressure remains to be determined.

Obesity is a multi-factorial, chronic disorder that has reached epidemic proportions in most industrialized countries and is threatening to become a global epidemic. Obese patients are at a higher risk from coronary artery disease, hypertension, hyperlipidemia, diabetes mellitus, certain cancers, cerebrovascular accidents, osteoarthritis, restrictive pulmonary disease, and sleep apnea. Obesity is a particularly challenging clinical condition to treat, because of its complex pathophysiological basis. Indeed, body weight represents the integration of many biological and environmental components. Efforts to develop innovative anti-obesity drugs have been recently intensified. In broad terms, researchers use different distinct strategies: first, to reduce energy intake; second, to increase energy expenditure; third, to alter the partitioning of nutrients between fat and lean tissue. In the present review we concentrate on the first of these strategies, by underlining the new pharmacological tools which are presently studied.
