diverticulosis is the name for a very specific change in the intestine: it forms protuberances in the intestinal wall, called diverticula. These are neither painful nor dangerous in themselves, but can inflame or be injured and bleed. The finding "diverticulosis" initially means only that there are several diverticula.

Diverticulosis: description

Diverticula around the colon are among the diseases of civilization in western countries today. Doctors assume that especially the increasingly Low-fiber diet In the case of diverticulosis, it plays an important role: too little fiber causes a hard and firm stool, which in most cases affects more frequently constipation manifests. The internal pressure in the intestine is increased, so that it can happen over the years that the intestinal mucosa bulges outwards in certain places. This happens more often in older people, because with them the connective tissue of the intestine is not so strong. It also happens that diverticulosis is particularly common in old age - in about two-thirds of the over-70s there are diverticula in the intestinal mucosa. However, in recent decades, more and more young people are prone to diverticulosis.

Basically, doctors distinguish two forms of diverticula:

  • Most often it comes to so-called wrong diverticos or pseudodiverticates. These account for up to 90 percent of diverticulosis cases in Germany. In doing so, the intestinal mucosa inverts outwards through a tiny gap in the muscular intestinal wall. Frequently, at these sites, blood vessels pass through the intestinal wall, supplying the intestine with blood.
  • Rare are true diverticulain which the muscle wall of the intestine also bulges outward. These diverticula are more congenital than diet-related and are more common in people in Asia.

While true diverticula usually occur in the ascending region of the colon (ascending colon), the more common in Europe false false diverticula form mainly in the descending colon (descending colon) and the subsequent, S-shaped transition to the rectum (sigmoid colon or sigmoid),

Diverticulosis: symptoms and diagnosis

In the case of diverticulosis, symptoms such as pain and indigestion usually do not last for a long time. The diverticula itself is not painful. However, depending on number, size and location, they may increase with time Irritable bowel-like symptoms to lead:

  • irregular bowel movements
  • constipation
  • diarrhea
  • mild pain in the left lower abdomen

However, in known diverticulosis symptoms such as severe pain, blood in the stool or a conspicuous constipation, this is usually a sign of inflammation (diverticulitis), an injured diverticulum or other complications.

However, diverticulosis often remains undetected and symptom-free (asymptomatic) for a long time and is a chance finding, for example as part of a colonoscopy (colonoscopy). Even on an X-ray with contrast agent in the intestine, the doctor can usually recognize the diverticulum well and make the correct diagnosis.

Diverticulosis: diet with fiber is the best therapy

Diverticulosis comes in most cases by a low-fiber diet, too little fluid and / or lack of exercise. All these factors are factors that promote constipation and promote the formation of diverticula in the long term. In addition, diverticulosis is more likely to cause complications such as diverticulitis or bleeding of the diverticulum due to certain nutritional problems.

Those who manage to switch diet and other lifestyle habits in existing diverticulosis can usually expect a good prognosis. Most important is:
  • a rich in fiber: Fruits, vegetables and wholegrain cereals are ideal sources of fiber. In addition, concentrated fiber sources such as oat bran or crushed flaxseed may be helpful.
  • more MoveDaily walks and regular endurance training (e.g., jogging, swimming) support bowel movement.
  • plentiful drink: At least two liters of water or tea a day make the chair "supple" and counteract diverticula.
