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

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.

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...

Any comments appreciated and advice about medication/prevention, etc. Mary. Answer: Dear Mary; Your observation is correct: a lot of the severe abdominal symptoms seem to diminish over time.
