By 2018, 42% of Americans were obese.While a majority of obese individuals at any given time are attempting to lose weight and are often successful, research shows that maintaining that weight loss over the long term proves to be rare. The reasons for weight cycling are not fully understood but may include decreased energy expenditure combined with an increased biological urge to eat during and after caloric restriction. More studies are needed to determine if weight cycling and yo-yo dieting contribute to inflammation and disease risk in obese individuals.Although there is no effective, well-defined, evidence-based intervention for preventing obesity, obesity prevention will require a complex approach, including interventions at community, family, and individual levels. Changes to diet and exercising are the main treatments recommended by health professionals. Diet quality can be improved by reducing the consumption of energy-dense foods, such as those high in fat or sugars, and by increasing the intake of dietary fiber. However, large-scale analyses have found an inverse relationship between energy density and energy cost of foods in developed nations. Medications can be used, along with a suitable diet, to reduce appetite or decrease fat absorption. If diet, exercise, and medication are not effective, a gastric balloon or surgery may be performed to reduce stomach volume or length of the intestines, leading to feeling full earlier, or a reduced ability to absorb nutrients from food.Obesity is a leading preventable cause of death worldwide, with increasing rates in adults and children.
Susacs syndrome (retinocochleocerebral vasculopathy) is a very rare form of microangiopathy characterized by encephalopathy, branch retinal artery occlusions and hearing loss. The cause is unknown but it is theorized that antibodies are produced against endothelial cells in tiny arteries which leads to damage and the symptoms related to the illness. Despite this being an extremely rare disease, there are 4 registries collecting data on the illness; two are the United States, one in Germany, and one in Portugal. Presentation
Susacs syndrome is named for Dr. John Susac (1940–2012), of Winter Haven, Florida, who first described it in 1979. Susacs syndrome is a very rare disease, of unknown cause, and many persons who experience it do not display the bizarre symptoms named here. Their speech can be affected, such as the case of a female of late teens who suffered speech issues and hearing problems, and many experience unrelenting and intense headaches and migraines, some form of hearing loss, and impaired vision. The problem usually corrects itself, but this can take up to five years. In some cases, subjects can become confused. The syndrome usually affects women around the age of 18 years, with female to male ratio of cases of 2:1. William F. Hoyt was the first to call the syndrome "Susac syndrome" and later Robert Daroff asked Dr. Susac to write an editorial in Neurology about the disorder and to use the eponym of Susac syndrome in the title, forever linking this disease with him.
