Pain in the small intestine


There are various disorders that can cause pain in the Intestines being able to lead. However, it is often not possible to precisely localize the pain. Often the patients feel an unspecific pain in the abdomen. This can acute and very strong occur, or also chronic and one dull Have character. Some disorders lead to less of one persistent pain, but rather to one colickypain in waves.

Ileus of the small intestine

A small intestinal ileus is caused by a mechanical blockage of the small intestine (mechanical ileus) and its function, or by paralysis of the intestinal peristalsis (paralytic ileus) due to massive inflammation in the abdomen. Due to the loss of function in a mechanical ileus, the intestinal contents can no longer be transported. This leads to a blockage of the intestines. After a while this can lead to massive colicky pain in the abdomen, but also to a feeling of fullness, nausea and vomiting.
The pain is caused by the intestine trying to transport the intestinal contents, which is not possible due to the ileus. The mechanical ileus urgently needs surgical treatment.
The cause must be found and eliminated. Paralytic ileus is usually just a symptom of another disease, such as peritonitis. The cause of the pain is less the ileus than the underlying disease, which needs urgent treatment.

Crohn's disease

Also chronic inflammatory diseases of the intestine, like the M.orbus Crohn, can lead to pain in the abdomen. This is a autoimmune conditional inflammation of all intestinal wall layers. It can too Erosions and Ulceration the intestinal wall and inflammation-related pain. Crohn's disease can occur in the entire gastrointestinal tract and leads to pain irregular bowel movements, Food intolerance and Weight loss. Therapy can only be symptomatic Immunosuppression or Operations respectively.

Meckel's diverticulum

Another cause of pain in the small intestine can be Meckel's diverticulum be. This is one Protuberance of the small intestine and usually does not cause any discomfort. However, the Meckel's diverticulum is partial open, so intestinal contents can get into the protuberance and to Inflammation to lead. In this case you will experience the same symptoms as with one Appendicitis on. It comes to fever, nausea, Nausea and massive right-sided abdominal pain. The only sensible therapy then is surgery and removal of the inflamed one Diverticulum.

Duodenal ulcer

That too Duodenal ulcer or one Duodenitis (Inflammation of the duodenum) can cause pain. This is an ulcer of the Duodenumwhich crosses the muscle layer under the mucous membrane. First, there are unspecific symptoms such as nausea, Bloating, irregular bowel movements and Vomit on. Typically, after a while, patients suffer from one Fasting painwhich initially improves through food intake. The pain is often in the Epigastric region or around the belly button indicated around. In some cases, duodenal ulcer has no symptoms and is then a chance diagnosis. The cause of this ulceration in the small intestine is often a bacterium that Helicobacter pylori. Then it stands Eradication of the pathogen in the foreground. This can be divided into three different Antibiotics treat very well. Otherwise the avoidance of stress and mucous membrane irritating drugs in the foreground.

Whipple's disease

Another disease caused by a bacterium is the Whipple's disease. This is caused by the bacterium Tropheryma whipplei evoked and leads to one Lymphatic congestion in the intestine. As a result, nutrients can no longer be absorbed from the intestine and the Villi atrophy. It comes to typical Malabsorption symptoms With Weight loss, diarrhea and stomach pain. Furthermore, extraintestinal symptoms such as fever, Heart failure and Joint inflammation occur. The therapy consists of a longer duration Antibiotic therapy. In addition, should Vitamins, Trace elements and Electrolytes fed to a Nutritional deficiency to avoid.

Furthermore, rotations of the bowel can occur too severe pain by interrupting the Blood supply to lead. This is called Volvolus designated. This allows it to Intestinal obstruction up to the destruction of the affected tissue. Such a volvolus can do both acute, as well as chronic occur. The acute bowel rotation goes with it Vomit, shock, Peritonitis and one distended upper abdomen hand in hand.
A chronic recurrent volvolus leads to Malabsorption symptoms, constipation and unspecific stomach pain. This symptomatic phase can also be interrupted by symptom-free intervals. Therapy consists in the surgical restoration of the original anatomical position of the small intestine. Especially with an acute rotation of the small intestine is a fastest possible operation Urgently indicated to avoid the loss of the intestinal section. A chronic volvolus can be surgically fixed on a trial basis in order to avoid further twisting of the bowel.


The Intussusception leads to symptoms similar to those of volvolus. In doing so, the small intestine does not twist, but rather one Invagination a section of the intestine in the longitudinal axis of the intestine. Here too, the Blood supply of the intestine and the symptoms of an acute intestinal obstruction arise. Are particularly common Infants up to the age of two affected. In the acute case of intussusception, sudden ones occur cramping abdominal pain, Vomit and paleness on. Another typical is a very high-pitched screams of toddlers and Tightening the legs. In adults, these symptoms often develop slowly in the form of a chronic Intestinal obstruction. For both children and adults, the surgery in the foreground. Here, the affected section of the small intestine should be loosened again. If part of the intestine has died due to the interruption of the blood supply, it must be removed. As a rule, intussusception does not occur more than once, so that in most cases patients do not have to expect any new intussusception after the operation.
