From constipation or vice versa from an excess of fiber, it happens.
Sometimes the intestine is twisted, the blood vessels in it are pinched, the contents of the intestine get stuck and do not go further. From this, the stomach swells, everything hurts badly, a stool with blood appears, and you can die.
It should be noted right away that the intestine is not a hose that can be randomly tied in knots. The intestine is glued to the wide mesentery, which contains the blood vessels and supports the intestine.
The mesentery is like a tablecloth hanging from the table. On the edge of such a tablecloth, instead of flowers and ruffles, there will be a gut.
Imagine you decide to knot the edge of the tablecloth. It is not so easy. You need to pull up a larger tablecloth with both hands, dump everything from the table, and only then can you tie something there. That is, it is difficult to get volvulus on a healthy intestine.
In fact, of course, there will be no knots there, but rather it will look like a rolled towel. Well, when a wet towel is squeezed out. Have you presented?
In adults, volvulus is more likely to occur in the sigmoid colon and less commonly in the cecum. Everything else is already rare.
The sigmoid colon is located at the very end of the intestine. She's next to last in line to exit after the rectum. That is, there are a lot of poop in it.
If a person has constipation, then this overflowing and swollen sigmoid colon can, with an effort, roll over from side to side and twist the mesentery with the arteries feeding the intestine. Just like twisting a towel. If the intestine is not unscrewed in time, then it will die and fall apart from the disturbed blood supply. Well, after that, the owner of the intestine will also die.
This usually happens to old and sick people, especially those who have constipation, or the intestines do not work well from some kind of disease of the nervous system.
Sometimes everything happens not so dramatically, but rather slowly and gradually.
They say that in poorer countries, where people are forced to eat a lot of fiber, volvulus of the sigmoid colon is also common.
In pregnant women, a similar misfortune happens. Or even with different adhesions in the abdomen. Just after the appendicitis that we discussed with you, adhesions can lead to volvulus of the cecum:
In short, a typical surgical travel candidate is an elderly, sick man with constipation.
Look what happens: on the one hand, lack of fiber and constipation leads to bloat, and on the other hand, excess fiber also leads to bloat. Any extremes are not good for us.
Is everything clear with the reasons and mechanisms?
