Depending on the location, abdominal pain can have different causes. In some cases, it is possible to deduce the possible cause from the localization of the pain. Diseases of the intestine, i.e. the intestinal loops, usually cause abdominal pain that is localized in the middle to lower abdomen.
Since the intestine extends over the entire abdomen, pain in a loop of intestine can occur on the right, left or in the middle.
There are several conditions that can cause a loop of bowel pain.
The uppermost part of the intestine is the duodenum (Duodenum). Ulcers that resemble gastric ulcers can develop here. Such ulcers can cause severe pain, mostly localized in the upper abdomen.

Entrapment of parts of the intestine (hernias) can occur in inguinal hernias, umbilical hernias and incisional hernias. A small part of the intestine passes through a gap in the abdominal wall or through the inguinal canal; this is called a rupture. If it is narrowed within this gap, it is called an entrapment. Such entrapment can cause severe pain.
An insufficient supply of the intestines with blood (Intestinal ischemia) can cause severe pain in the affected intestinal loops.
Also an acute intestinal obstruction (Ileus), in which the intestinal contents can no longer be transported due to an obstacle.
Furthermore, inflammatory bowel diseases such as Crohn's disease or ulcerative colitis can lead to abdominal pain.

Diverticulitis, an inflammation of large intestinal bulges, also leads to pain in the affected intestinal sections.
But even relatively harmless diseases, such as simple gastrointestinal flu, can cause pain in the intestinal area.
$config[ads_text2] not foundIn some people, small protrusions of the mucous membrane, the so-called diverticula, develop in old age. One speaks of diverticulosis. In most cases, such diverticulosis is localized in the sigmoid colon, part of the large intestine.
Risk factors for the development of diverticula are a low-fiber diet and - as a result - frequent constipation. Diverticulosis in itself does not cause any symptoms. However, inflammation in the area of the diverticula can occur, which is referred to as diverticulitis. This is accompanied by pain in the left lower abdomen. A fever can also occur.

In rare cases, the bowel can turn on itself. One then speaks of a bowel entanglement. As a result of this twisting, the intestinal contents can no longer be transported and the blood supply to the intestine is often impaired. There is severe pain in the affected section of the intestine.
A bowel entanglement is potentially life-threatening, as the affected part of the bowel can die without intervention. Surgical treatment is usually necessary.

A loop of intestine can become trapped in various hernias (inguinal hernia, umbilical hernia, incisional hernia) in which parts of the intestine can penetrate and become narrowed through a gap in the abdominal wall.
Small breaks without entrapment usually do not cause any discomfort, but can be felt as a small protrusion through the skin.
If an entrapment occurs, the blood supply to the stuck intestine can be significantly restricted and the intestinal contents can no longer be transported. There is severe pain in the affected section of the intestine. If a loop of intestine is trapped, rapid surgical treatment is usually necessary.
Pain in a loop of intestine located in the right half of the abdomen can indicate various possible diseases.
In the case of an entrapment as part of a hernia, a loop of intestine on the right side may be involved. For example, with a right-sided hernia (Inguinal hernia) or with a right-sided hernia (Incisional hernia).
In the case of an incisional hernia, a break occurs in the area of a scar, for example after previous operations in the abdomen. Even if the intestine is insufficiently supplied with oxygenated blood, parts of the intestine located on the right side can be involved and right-sided abdominal pain can occur.
Chronic inflammatory bowel diseases such as Crohn's disease or ulcerative colitis can also cause right-sided abdominal pain. Irritable bowel syndrome can cause pain in any part of the bowel.

The most typical cause of left-sided lower abdominal pain is sigmoid diverticulitis, i.e. the inflammation of large intestinal protuberances in the area of the so-called sigmoid colon.
However, entrapment in fractures such as a left inguinal hernia or incisional hernias can also cause pain in the area of a loop of intestine on the left.
An intestinal obstruction can be localized in any area of the intestine and thus cause abdominal pain on the right as well as on the left or in the middle. A bowel obstruction is usually caused by obstacles in the passage. These include, for example, tumors or adhesions after previous operations.
If there is pain in the bowel area, the triggering cause must be found. First, the anamnesis takes place, so it is asked exactly since when the symptoms exist, how often they occur and how long they last, what kind of pain they have, where they are located and whether there are accompanying symptoms. The presence of comorbidities is also asked about.
On the basis of a clinical examination of the abdomen, the next clues for the possible cause can be gathered. This is usually followed by an ultrasound scan of the abdomen and blood tests.
It is not uncommon for further imaging diagnostics such as a CT or MRI examination to be necessary.
The accompanying symptoms depend on the triggering cause. Often a cause can already be suspected from a certain symptom constellation.
The type of treatment depends largely on the cause of the pain in the loop of intestine.
$config[ads_text1] not foundSome diseases require quick action in terms of a surgical procedure. These include intestinal obstruction, entrapment of an intestinal loop, intestinal entanglement and intestinal ischemia. Only in rare cases is this diagnosed not operated on. For example, if the risk of anesthesia and surgery is too high, as can be the case with patients with other serious pre-existing conditions.
Antibiotic therapy is often necessary for diverticulitis. In some cases, however, it is sufficient to take a food break and rest.
If there is a chronic inflammatory bowel disease, long-term drug therapy is necessary in most cases. Medications of choice include mesalazine, steroids, immunosuppressants, and biologics.
In the case of an ulcer in the area of the duodenum, acid-inhibiting drug therapy is started. Avoiding triggering factors such as alcohol, nicotine, stress and painkillers from the group of non-steroidal anti-inflammatory drugs such as ibuprofen or ASA is also crucial.
In the case of gastrointestinal flu, sufficient fluid intake is usually sufficient, and the symptoms disappear on their own within 1-3 days.
There is currently no specific therapy for treating irritable bowel syndrome. Different approaches include eating a special high-fiber diet and taking probiotics.
The prognosis of pain in the area of an intestinal loop depends largely on the triggering cause. While a viral disease of the gastrointestinal tract is usually harmless and regresses on its own after a few days, diseases such as intestinal obstruction, intestinal ischemia or intestinal obstruction are in many cases life-threatening if left untreated.
Rapid therapy is necessary.
Other diseases such as Crohn's disease or ulcerative colitis are often chronic and recurrent, i.e. in recurring attacks.
