'''Autoimmune gastrointestinal dysmotility''' ('''AGID''') is an [[autoimmune disease]] [[autonomic neuropathy]] affecting the [[gastrointestinal]] organs and [[digestive system]] of the body. Dysmotility is when the strength or coordination of the [[esophagus]], [[stomach]] or [[intestines]] [[muscles]] do not work as they should.<ref>Bolen, Barbara Bradley.

{{Short description|A disorder affecting gastrointestinal motility due to autoimmune causes}}
==Presentation==
'''Autoimmune gastrointestinal dysmotility''' (AGID) is a rare disorder characterized by abnormal movement of the muscles in the gastrointestinal tract due to an autoimmune response. This condition can affect any part of the gastrointestinal tract, leading to a variety of symptoms and complications.
=== Associated illnesses ===
==Pathophysiology==
Often AGID is a symptom of other problems, including [[colon cancer]], [[lupus]], lung, breast, or [[ovarian]] [[carcinoma]] or [[thymoma]]. or other diseases. [[Irritable bowel syndrome]] (IBS) is the most recognized form of AGID{{Citation needed|date=December 2014}}.
AGID occurs when the body's immune system mistakenly attacks the nerves and muscles of the gastrointestinal tract. This autoimmune attack can lead to inflammation and damage to the [[enteric nervous system]], which is responsible for controlling the motility of the gastrointestinal tract. The resulting dysmotility can cause either slowed or uncoordinated movement of the digestive tract, affecting the normal process of digestion and absorption.
 
==Symptoms==
== Diagnosis ==
The symptoms of AGID can vary widely depending on which part of the gastrointestinal tract is affected. Common symptoms include:
AGID is diagnosed with a complete medical history, exam of patients motility and with special blood tests looking for autoantibodies consistent with neurologic autoimmunity.<ref>{{cite journal |doi=10.1016/j.cgh.2008.04.009 |title=Serologic Profiles Aiding the Diagnosis of Autoimmune Gastrointestinal Dysmotility |year=2008 |last1=Dhamija |first1=Radhika |last2=Tan |first2=K.

A disorder affecting gastrointestinal motility due to autoimmune causes


Autoimmune gastrointestinal dysmotility (AGID) is a rare disorder characterized by abnormal movement of the muscles in the gastrointestinal tract due to an autoimmune response. This condition can affect any part of the gastrointestinal tract, leading to a variety of symptoms and complications.

Pathophysiology[edit]

AGID occurs when the body's immune system mistakenly attacks the nerves and muscles of the gastrointestinal tract. This autoimmune attack can lead to inflammation and damage to the enteric nervous system, which is responsible for controlling the motility of the gastrointestinal tract. The resulting dysmotility can cause either slowed or uncoordinated movement of the digestive tract, affecting the normal process of digestion and absorption.

Symptoms[edit]

The symptoms of AGID can vary widely depending on which part of the gastrointestinal tract is affected. Common symptoms include:

These symptoms can lead to significant discomfort and may severely impact a patient's quality of life.

Diagnosis[edit]

Diagnosing AGID can be challenging due to its rarity and the overlap of symptoms with other gastrointestinal disorders. A comprehensive evaluation typically includes:

Treatment[edit]

Treatment of AGID focuses on managing symptoms and addressing the underlying autoimmune process. Therapeutic approaches may include:

Prognosis[edit]

The prognosis for individuals with AGID varies depending on the severity of the condition and the response to treatment. Early diagnosis and appropriate management can improve outcomes and quality of life for many patients.
