The cat's stomach is a sac-like structure designed to store large volumes of food and continue the digestive process. The esophagus carries food to the stomach, where it enters via a valve-like structure called the cardiac sphincter. On the interior surface of the stomach is a series of folds called gastric folds. These folds function to help grind and digest food. The inner stomach lining secretes acids and enzymes to break down food. Once the initial stomach digestive process is complete, the partially digested food exits the stomach through the pyloric sphincter area and then enters the duodenum (first segment of the small intestine). Once eaten, most food leaves the stomach within twelve hours after entering.

If you suspect that you have sleep apnea, the usual first step is to discuss your suspicions with your primary care physician. If you donโ€™t have a primary care physician, you can go directly to a clinician who is a sleep specialist. But check your health care insurance coverage first. Some policies require you to see a primary care physician first, and some policies limit the sleep centers and testing facilities whose services they will pay for. Unfortunately, you may discover that your policy offers limited or no coverage for the diagnosis and treatment of sleep apnea, in which case you may wish to switch insurers if and when you can.

Obesity is one of the most pervasive, chronic diseases in need of new strategies for medical treatment and prevention. As a leading cause of United States mortality, morbidity, disability, healthcare utilization and healthcare costs, the high prevalence of obesity continues to strain the United States healthcare system. Obesity is defined as excess adipose tissue. There are several different methods for determining excess adipose (fat) tissue; the most common being the Body Mass Index (BMI) (see below). A fat cell is an endocrine cell and adipose tissue is an endocrine organ. As such, adipose tissue secretes a number of products, including metabolites, cytokines, lipids, and coagulation factors among others. Significantly, excess adiposity or obesity causes increased levels of circulating fatty acids and inflammation. This can lead to insulin resistance, which in turn can lead to type 2 diabetes.

The etiology of BOO is diverse and definitely gender specific. Often anatomic causes induce functional abnormality that remains somewhat unique for each individual, regardless of sex. A full appreciation of the possible etiologies of obstruction is necessary in order to identify overt and more subtle scenarios. In women, iatrogenic causes of obstruction are the most common. Other entities account for far fewer of the cases. The obstruction evaluation in women is somewhat more diverse in terms of modalities used, with no single grouping of techniques that are generally apropos. Individualized evaluation remains a tenet of analysis, and urodynamic criteria used to diagnose BOO in women continue to evolve.

Tourette syndrome (also called Tourette's disorder or simply, "Tourette's") is an abnormal neurological condition characterized by motor and vocal tics. Tics are involuntary, rapid, sudden repetitive movements or sounds. Tics can be classified in a variety of ways. Motor tics can affect any part of the body including the head, neck, face, arms, shoulders, hands, feet, or legs. Facial tics, especially eye blinking, are usually the first symptoms of TS. Vocal tics are sounds that are made involuntarily. Vocal tics can include clearing the throat, coughing, sniffing, grunting, yelping, or shouting. In a few cases, vocal tics can include strange, inappropriate, or obscene words and phrases (called coprolalia). Vocal tics can also appear as constantly repeating the words of others (echolalia).

People with lactose intolerance are unable to fully digest the sugar (lactose) in milk. As a result, they have diarrhea, gas and bloating after eating or drinking dairy products. The condition, which is also called lactose malabsorption, is usually harmless, but its symptoms can be uncomfortable. A deficiency of lactase โ€” an enzyme produced in your small intestine โ€” is usually responsible for lactose intolerance. Many people have low levels of lactase but are able to digest milk products without problems. If you're actually lactose intolerant, though, your lactase deficiency leads to symptoms after you eat dairy foods.
