Psychogenic Adipsia Presenting as Recurrent Functional Vomiting and Hypernatremia.
The Journal of the American Osteopathic Association
|April 28, 2020
Summary
This study presents a rare case of hypernatremia caused by psychogenic adipsia, a condition of excessive thirst. Treatment for major depression resolved the patient's symptoms, emphasizing a comprehensive approach to unexplained hypernatremia.
Area of Science:
- Nephrology
- Endocrinology
- Psychiatry
Background:
- Hypernatremia, characterized by elevated serum sodium, arises from an imbalance between free water and sodium levels.
- Common etiologies include renal/gastrointestinal fluid loss, hypothalamic damage, and endocrine disorders.
Observation:
- A rare case of hypernatremia was observed in a 46-year-old woman with intractable vomiting.
- The patient's condition was secondary to psychogenic adipsia, a psychological disorder affecting thirst regulation.
Findings:
- The patient's hypernatremia and associated symptoms resolved following treatment for major depression.
- This suggests a significant link between psychiatric conditions and fluid balance abnormalities.
Implications:
- This case underscores the importance of considering psychological factors in the differential diagnosis of unexplained hypernatremia.
- A holistic, multidisciplinary approach is crucial for managing complex cases involving both physiological and psychological components.

01:22Pathophysiology of Vomiting
2.4K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

01:30Bulimia Nervosa
579
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

01:25Regulation of Water Intake
2.5K
Osmolality refers to the number of solute particles per kilogram of solvent in a solution. Plasma osmolality specifically indicates the total number of solute particles per kilogram of water in blood plasma. This value reflects the body's hydration status and is tightly regulated through mechanisms controlling water intake and output. While water consumption is a conscious decision, the body has intrinsic regulatory systems to maintain fluid balance. Dehydration, a state of water deficit...

01:29Disorder of Water Balance
2.3K
Water balance disorders are medical conditions that occur when there is a deviation from the body's water volume or osmolarity, disrupting normal homeostasis and leading todehydration, hypotonic hydration, hyperhydration, edema, or water intoxication.
Dehydration
Dehydration occurs when the body loses fluids (particularly water).
Causes:
The major causes of dehydration include excessive sweating, fever, vomiting, diarrhea, and diuresis.
Signs and Symptoms:

01:29Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists
727
Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.

01:20Taste Buds and Receptors
4.3K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
