Without environmental protection and regulation, 1  Industry would have unlimited ability to produce chemicals for use as pesticides, additives, etc without being required to measure their effects on people or their accumulation in water or soils and their impact on the ecosystem.
Bowel obstruction usually presents with colicky pain, abdominal distension, vomiting and constipation. Abdominal xray in erect posture will confirm the diagnosis. So if you have the above symptoms report to ER to rule out intestinal obstruction.
Symptoms depend on the location of the obstruction and whether it is partial or complete. Blockage in the small intestine causes intense episodes of abdominal pain and vomiting that may lead to dehydration and shock. Symptoms (intractable constipation and pain) develop more slowly in large-bowel (colon) obstruction. Blockage of the small intestine is much more common than blockage of the large intestine.
