Gastroesophageal Reflux Disease

Gastroesophageal reflux disease also known as GERD, is a condition in which the stomach contents leak backwards from the stomach into the esophagus. It is a chronic digestive disorder and since the stomach has acidic contents it irritates the lining of the esophagus.

Pathophysiology: Normally when we eat, the food passes from our mouth through the esophagus to the stomach. A ring of muscle fibers in the lower esophagus that make up the lower esophageal sphicture (LES) normally prevent the gastric contents from backing up into the esophagus.
Reflux occurs when LES pressure is deficient or when the pressure within the stomach exceeds LES pressure.

Risk Factors: There are certain situations in which a person may be predisposed to develop GERD. These may include:

  • Obesity
  • Pregnancy
  • Smoking
  • Excess use of Alcohol
  • Use of certain drugs  e.g : anticholinergics, diazepam, morphine, bronchodialtors.

Cognitive Therapy In Psychiatry.

Introduction:
Cognitive therapy is a psychological treatment method that helps patients correct false self-beliefs that contribute to certain moods and behaviors.
The basic principle behind cognitive therapy is that a thought precedes a mood and that both are interrelated with a person’s environment, physical reaction, and subsequent behavior. Therefore, changing a thought that arises in a given situation changes mood, behavior, and physical reaction. Although it is unclear who benefits most from cognitive therapy, motivated patients who have an internal center of control and the capacity for introspection likely would benefit most.

Background: Cognitive therapy was developed by American scientist Aron T Beck. in the 1960' s. It is based on a cognitive model which states that thoughts, feelings and behavior are all connected. Difficulties can be overcomed and goals achieved if inaccurate and negative  thinking can be controlled. This form of psychotherapy has been found to be effective for a large number of psychiatric disorders including but not limited to depression, anxiety, eating disorders,  substance abuse and personality disorders.

Essential Components of CBT:
CBT is based on the idea that our thoughts causes our feeling and behavior so if we can change the way we feel we can change the situation even though the situation has not really changed.

The basic steps or components of this therapy are briefly describes here:

1. Building trust and rapport with the patient is very important as in any other case and helps in getting close to the patient and understand him more accurately.

2. The basic question to ask a patient is is reporting a distressing situation or dysfunctional behavior is " what is going On in your mind right now?" This helps in identify the negative thinking and an approach to think differently.

3. In the first step the therapist helps the patient identify the problematic belief. This is known as functional analysis. The process may sometimes be difficult initially but ultimately leads to self discovery and insights.

4. The second part of CBT focuses on the actual behaviors that are contributing to the problem. The patient begins to learn new skills and tries to put them in real world situations.

5. CBT is a gradual process that helps in changing the behavior in a slow step wise process.
