Or are you one of those who need chilly cold waves of cold air only at the sleep time at night? As with a flight, it is possible on a broad canal for more than one boat to be in a staircase at the same time, but managing this without waste of water requires expertise. Waste dumped in landfills can also generate another common pollutant in the form of methane, which can be dangerous in several ways. Ask your A/C professional if they can do this for you, as this will help you stay on track of any work that need to be done. Use very fresh cucumbers if you want them to stay crisp. If you don’t want to stop your vehicle periodically so you can crawl around under the trailer with a tire gauge, a remote tire pressure monitoring system is invaluable. Cut-in pressure is 20 psi to 25 psi below cut-out pressure. Imaging studies, including ultrasound examination, computerized tomography (CT), and magnetic resonance imaging (MRI), are particularly useful in defining the cause of distention that is due to enlargement of the abdominal organs, abdominal fluid, and tumor. If the bloating or distention is continuous rather than intermittent, then enlargement of abdominal organs, abdominal fluid, tumors, or obesity causes to be considered.

Then, during the next hour or two, the stomach secretes acid and fluid, which mix with the food and assist indigestion. To make matters worse, the distention that is caused by the physical obstruction stimulates both the stomach and intestines to secrete fluid, which adds to the distension. A delay in emptying of the radioactivity from the stomach can be caused by any condition that reduces emptying of the stomach (for example, pyloric stenosis, gastroparesis). For example, scarring of the pylorus (pyloric stenosis) can obstruct the opening from the stomach into the intestines, thereby blocking the complete emptying of the stomach. For gastric emptying studies, a test meal that is labeled with a radioactive substance is eaten and a Geiger counter-like device is placed over the abdomen to measure how rapidly the test meal empties from the stomach. For example, if the air is in the stomach, emptying the stomach is likely to be the problem.

The best general test is a 72-hour collection of stool in which the fat is measured; if maldigestion and/or malabsorption exist because of pancreatic insufficiency or diseases of the lining of the small intestine (for example, celiac disease), the amount of fat will increase before proteins and starches in the stool. For example, the problem may be the foul odor of the gas (often due to ingestion of sulfur-containing foods), the lack of ability to control (hold back) the passing of gas, or the soiling of underwear with small amounts of stool when passing gas. Dietary fat reaching the small intestine causes the transport of digesting food, gas, and liquid within the intestines to slow. X-rays of the small intestine, in which barium is used to fill and outline the small intestine, are particularly useful for determining whether there is an obstruction of the small intestine. There are 5 major types of AC for people to choose from. Fructose, on the other hand, may be digested normally but may pass so rapidly through the small intestine that there is not enough time for digestion and absorption to take place. The bloating may become aggravated or even progress to distention if the meal contains substantial amounts of fat, perhaps because fat slows the transit of gas and digestion of food out of the stomach and small intestine.

If a diet history reveals the consumption of large amounts of milk or dairy products (lactose), sorbitol, or fructose, then the maldigestion and malabsorption of these sugars may be the cause of the distention. Sugar fructose, a commonly used sweetener, like lactose and sorbitol, also may cause abdominal bloating/distention and flatulence. Specific tests can be done for maldigestion of individual sugars that are commonly maldigested, including lactose (the sugar in milk) and sorbitol (a sweetener in low-calorie foods). However, the problem that can occur with fructose is different from that with lactose or sorbitol. Thus, as already described, lactose and sorbitol may be poorly digested by the pancreatic enzymes and small intestine. Accumulating evidence shows that some patients with abdominal bloating and distention due to gas may have a functional abnormality of the intestinal muscles that prevents gas from being normally transported through the intestine and expelled. An obstruction in the small bowel, which is most commonly due to adhesions (scarring that kinks the intestines) from previous surgery, is another cause of intermittent abdominal distention. These problems, however, are not due to excessive gas production, and their treatment is different. Increased flatulence may not always occur; however, gas can be eliminated in other ways such as absorption into the body, utilization by other bacteria, or possibly, elimination at night without the awareness of the gas passer.
