FBD full form in medical term is Functional Bowel Disorder, which includes a diverse range of conditions that adversely affect the digestive tract. Simply put, functional bowel disorder encompasses all those conditions that lead to digestive discomfort and affect the gastrointestinal system. While some impact the large intestine, some affect the small intestine.
Bowel disorder is a broad term that comprises multiple kinds of disorders, such as functional bowel disorders (irritable bowel syndrome, malignant bowel disorders, inflammatory bowel disorder, etc.).
One with Functional Bowel disorder may experience few signs and symptoms. However, they can differ from person to person and disorder. While some signs are common in all kinds of FBD, these symptoms are bloating, abdominal pain, constipation, nausea, gas, vomiting, diarrhoea, etc.
Although researchers have not been successful in detecting the cause of FBD, according to studies, FBD results from problems in the way the intestines work to absorb and digest food. If left untreated, the development of FBD can be severe. The risk will increase if you are female, have a family history, are addicted to alcohol or smoking, or suffer from chronic stress.
