Coffee Reduces Risk of Bladder Cancer. Researchers have long considered smoking a risk factor for bladder cancer, a disease that strikes about 55,000 Americans each year. But the results of a new study published in the January 2001 issue of the Journal of Epidemiology and Community Health suggest that risk may be far higher than previously thought.
The causes of irregular bowel movements (such as constipation) may include any of the following: 1  Dietary changes. 2  Hormonal changes. 3  Side effects of medication.  Illness or the onset of digestive 1  disorders. Anatomical abnormalities.  Sedentary lifestyle.
Moreover, most people are irregular and do not have bowel movements every day or the same number of bowel movements each day. Medically speaking, constipation usually is defined as fewer than three bowel movements per week. Severe constipation is defined as less than one bowel movement per week. There is no medical reason to have a bowel movement every day. Going without a bowel movement for two or three days does not cause physical discomfort, only mental distress for some people. Contrary to popular belief, there is no evidence that toxins accumulate when bowel movements are infrequent or that constipation leads to cancer.
