Gas, also called flatus or flatulence, is air in the intestine that is passed through the rectum. Air that is passed from the digestive tract through the mouth is called belching .
Gas is formed in the intestines as food is being digested. Gas can make you feel bloated, which may cause crampy or colicky abdominal pain .
Gas can be caused by any of the following:
Eating foods that are difficult to digest, such as fiber . If you recently introduced fiber into your diet, having gas may be temporary. Give it a little time. Your body may adjust and stop producing gas.
Eating foods that you cannot tolerate -- for example, if you have lactose intolerance and eat dairy products
Irritable bowel syndrome
-- a chronic form of stomach upset that gets worse with stress
(when your body cannot absorb or digest a ...
Over the weekend, I noticed an interesting question in a column by The People’s Pharmacy’s Joe and Teresa Graedon that addressed the topic of flatulence due to diet. The person who wrote in said that her son is a vegetarian who eats a lot of beans and dairy for protein, as well as lots of vegetables. He especially eats a lot of broccoli, Brussels sprouts, cabbage and carrots. “He is so flatulent, we can hardly stand it,” the mother wrote.
Smelly gas is one thing, but as I did a little research, there can be other outcomes from gas, such as misdiagnosis of other health issues. For instance, gas in the intestines can cause severe pain for some people, leading to misdiagnosis for a more severe condition. When pain from gas is on the left side of the colon, doctors can confuse it with heart disease. When the pain is on the right side, doctors may suspect gallstones or appendicitis.
So what is gas? Why does it occur? Why does it become smelly? What foods caus...
If you have ever been sunburned, then you have experienced hypersensitivity. Your skin was very sensitive to light touch, warm water and clothing for days. Well, imagine if that sensitivity was being experienced in your gut. Some people are troubled by such a problem called visceral hypersensitivity .
The phenomenon of hypersensitivity involves the nervous system. At some point, the irritation to a particular organ system like the skin or the gut leads to the sensitization of the nervous system , the alarm system. In severe cases, the central nervous system becomes so hypersensitive that everything seems to hurt. Painful stimuli become even more painful; that sensitivity is called hyperalgesia . Even non-painful stimuli like touch become painful; this sensitivity is called allodynia . In the case of visceral hypersensitivity, everything from digestion to urination can become painful. Thus, many conditions are linked to visceral hypersensitivity like: noncardiac chest pain, nonulcer...
