FGIDs Article Additions
Psychosocial factors:

There is a strong link between FGIDs and psychosocial factors. Psychosocial factors influence the functioning of the GI tract through the brain-gut axis, including the GI tract's motility, sensitivity, and barrier function. Psychosocial factors also affect experience and behavior, treatment selection, and clinical outcome.

Psychological stress or one's emotional response to stress exacerbates gastrointestinal symptoms and may contribute to FGID development and maintenance. '''Specifically in children and adolescents, anxiety and depression may present as FGID-associated somatic complaints, such as nausea, vomiting, and abdominal pain. Similarly, anxiety in individuals with FGIDs is linked to greater pain severity, frequency, duration, chronicity, and disabling effects. This is because psychological stress can impact the gut's mucosal barrier functions, allowing bacteria and bacterial products to migrate and cause pain, diarrhea, and other GI symptoms. Conversely, since the brain-gut axis is bidirectional, GI inflammation and injury can amplify pain signals to the brain and contribute to worsened mental status, including anxiety and depression symptoms.'''

'''Individuals with FGIDs may also experience poor socialization. Due to the nature of the disease, individuals with an FGID may have difficulty with regular school or work attendance and participation in extracurricular activities, leading to isolation and a lack of peer support. This lack of peer support may lead to depression and loneliness, conditions which exacerbate FGIDs symptoms. In addition, children with FGIDs are more likely to experience bullying. As such, stressful situations which influence socialization (seen as either a lack thereof or negative experiences) may lead to an impaired functioning in patients with FGIDs.'''

Family interactions may also plays a role in the development of FGIDs through their effects on the physical and psychosocial functioning of an individual. Family factors which may influence the development of an FGID include child attachment style, maladaptive parenting behaviors (paternal rejection and hostility), and even the parents' health status, as children of chronically ill parents experience increased somatization, insecure attachment, and worsened biopsychosocial functioning. Each of these factors leads to the accumulation of stressors, which can ultimately lead to the development of an FGID. In addition, family units which have a member with an FGIDs diagnosis are more likely to face family functioning difficulties, including challenges to familial roles, communication, affective involvement, organization, and cohesion. These challenges arise due to the nature of the disease, and ultimately worsen symptoms for the FGID patient.

Treatments:[edit]
Psychotherapeutic Treatments:

'''Because FGIDs are known to be multifactorial with external stressors and environmental factors playing a role in their development, current research demonstrates that psychological treatments may be effective in relieving some symptoms of the disease. Interventions such as cognitive behavioral therapy (CBT), hypnotherapy, and biofeedback-assisted relaxation training (BART) each show promise in symptom reduction.''' Each of these therapies aims to alter an individual's thought patterns and behaviors while improving self-efficacy, which all work together to improve health outcomes.

Cognitive behavioral therapy is a treatment based on the theory that thinking affects one's feelings and behaviors. As such, alterations in one's thought process can have a positive or negative affect on actions and perceptions. Through the lens of FGIDs, a negative thought pattern may be associated with a negative physical experience of abdominal pain, discomfort, and general sickness. In theory, retraining the patient's thought patterns can alleviate these symptoms and improve quality of life. In patients with FGIDs, '''CBT is an effective treatment option; one study found 87.5% of participants to be completely pain-free following treatment. Internet-based CBT (iCBT) is similarly effective, and may be a good treatment option for individuals who either cannot afford or otherwise lack access to traditional CBT.'''

'''Hypnotherapy, another method for reducing symptoms of FGIDs, teaches users how to alter their perception of uncomfortable sensations in the body. Gut-directed hypnotherapy specifically gives greater improvements in symptoms than standard treatment of the disease.''' Research demonstrates directed hypnotherapy to be an effective mechanism of reducing visceral hypersensitivity (a low pain threshold of the internal organs) and sympathetic activity, due to the reduced activity of the anterior cingulated cortex and state of relaxation achieved during hypnosis. For patients with irritable bowel syndrome (IBS) and functional abdominal pain (FAP), hypnotherapy reduces pain intensity and frequency.

'''BART therapies monitor the physiological changes occurring with thoughts, feelings, and emotions. These therapies aim to teach patients how to visualize the effects of the interventions they are undergoing. BART is used to improve mood and somatic responses to anxiety disorders, which may relieve some of the psychological and physiological symptoms of FGIDs.''' The visual, real-time feedback given through BART empowers the patient to see the difference that the therapy is making, thus giving the patient control over the physiological components of the disease. This allows the patient to maximize their mind-body connection and eventually optimize symptom management and quality of life. BART allows the patient to break the positive feedback loop of anxiety and pain, thus reducing disease exacerbations.

Pharmaceutical Treatments:

'''Antidepressants have been thoroughly studied as a potential treatment for FGIDs. Tricyclic antidepressants (TCAs), selective serotonin reuptake inhibitors (SSRIs), and selective norepinephrine reuptake inhibitors (SNRIs) show the most promise in treating some of the symptoms of FGIDs. TCAs, specifically amitriptyline, show promising results when examining common FGIDs symptoms such as pain and poor quality of life. SNRIs also demonstrate pain-relieving qualities. SSRIs are less effective in pain management, but may reduce symptoms of anxiety and depression, which would, in turn, reduce some FGIDs symptoms.'''

The Brain-Gut Axis:

The brain-gut axis is a bidirectional mechanism in which psychosocial factors influence the GI tract and vice versa. Specifically, the emotional and cognitive centers of the brain influence GI activity and immune cell function, and the microbes within the gut regulate mood, cognition, and mental health. These two systems interact through several mechanisms. There are direct, physical connections between the central nervous system and nerve plexuses to the visceral muscles. In addition, neurotransmitters send signals related to thoughts, feelings, and pain regulation from the brain to the GI tract. The brain-gut axis influences the entire body through a variety of pathways; it regulates sensory, motor, endocrine, autonomic, immune, and inflammatory reactions. Within the physical and psychological interactions of FGIDs specifically, psychiatric disorders such as anxiety, depression, and even autism are well-linked to GI dysfunction. Conversely, functional GI diseases are linked to several comorbid psychiatric diseases. Negative emotions such as fear, anxiety, anger, stress, and pain may delay gastric emptying, decrease intestinal and colonic transit time, and induce defecation and diarrhea.
