Common diseases of the small intestine

There are many types of diseases in the small intestine, including small bowel pain, small bowel inflammation, small bowel obstruction. Some diseases of the small intestine affect the digestion of food and absorption of nutrients in the body. Diseases of the small intestine can lead to other complications if left untreated, so it is important to seek medical attention early if symptoms appear at first.

Signs and symptoms of small bowel disease vary from disease to disease, depending on the etiology and pathogenesis. Common symptoms suggestive of diseases of the small intestine may include:
Diarrhea Constipation Swollen, painful abdomen Bloating, bloating Nausea, vomiting Blood in stools or blood in vomit Suded weight loss

Many methods are used to diagnose diseases of the small intestine including:
Advanced imaging tools including CT and MRI Colonoscopy Colonoscopy Immunohistochemical testing (FIT) is a Newer versions of the fecal occult blood test (FOBT) can be used to detect small traces of blood in the stool. Blood tests Contrast X-ray Capsule endoscopy. The capsule - about the same size and shape as a vitamin tablet - is swallowed by the patient and contains a small camera that takes pictures of the small intestine. Capsule endoscopy is performed to provide a more detailed view of the upper gastrointestinal tract that would otherwise be missed if viewed by traditional endoscopic means.

3.1 Peristalsis disorders, pseudo-obstruction of small intestine Abnormal peristaltic patterns in the small intestine can lead to the manifestation of symptoms of small bowel obstruction. These symptoms are:
Stomach bloating Pain Pain Nausea Vomiting Constipation Inability to defecate Symptoms will vary in their severity or frequency, but people will usually have these symptoms. symptom-free period.
These symptoms can be caused by weak contractions or by asynchronous contractions of the small bowel segments. Weak contractions of the small intestine are caused by abnormalities in the muscles and are often associated with diseases such as scleroderma. Connective tissue disorders can cause the intestines to swell so that the muscles cannot contract as they should to transport the contents of the intestinal lumen through the digestive system.
Others have contractions that are strong enough, but they are too disorganized or do not help form peristalsis to move food. This type of motility disorder is caused by an abnormality in the nerves, leading to an abnormality in the coordination or synchronization of intestinal contractions. In the case of pseudo-obstruction of the small intestine due to neurological causes, contractions can occur simultaneously over most segments of the small intestine, even causing food to move upstream.
3.2 Overgrowth of the small intestine microflora When the inside of the small intestine contains too many harmful bacteria, imbalance in the intestinal flora can lead to manifestations of:
Abdominal distention, bulging Painful Diarrhea This condition is commonly known as inflammatory bowel disease. Symptoms occur soon after eating because bacteria in the intestines begin to consume food in the small intestine before it can be absorbed. These bacteria produce hydrogen and other gases that cause bloating and diarrhea . Small intestinal bacterial overgrowth is the result of abnormal small bowel movements. When bowel movements are not stable enough to keep fluids and food one way, bacteria will not be expelled and grow out of control.

3.3 Short bowel syndrome Short bowel syndrome is a group of problems associated with malabsorption of nutrients that commonly occurs in people who have had at least half of their bowel removed. length of their small intestine. People with short bowel syndrome cannot absorb enough water, vitamins, and other nutrients from food to sustain life.
Diarrhea is the main symptom of short bowel syndrome and can lead to dehydration, malnutrition and rapid weight loss. These problems can be serious and can be fatal if not treated appropriately. Other symptoms of short bowel syndrome can include: cramping, bloating, heartburn, weakness, and fatigue.
Treatment of short bowel syndrome may include the use of oral rehydration solutions, parenteral nutrition, enteral nutrition, and medication. Bowel transplant surgery may be an option for some patients. Researchers are studying how to help the small intestine left over after surgery adapt and function better.
