All sources must be within five years (). Case Study 3: Disorders of Fluid and Electrolyte Balance Amanda is an 18-year-old with anorexia nervosa.
She was recently admitted to an eating disorders clinic with a BMI of 13.9, and although she was a voluntary patient, she was reluctant about the treatment. She was convinced she was overweight because her clothes felt tight on her. She complained that even her hands and feet “were fat.” One of her nurses explained that a protein in her blood was low. The nurse further explained that, as difficult as it may be to believe, eating a normal healthy diet would make the “fat hands and feet” go away. What protein do you suspect the nurse was referring to?
How would a deficiency in this protein contribute to edema? What is the difference between the physiology of pitting and nonpitting edema? Because of her weakened condition, Amanda was moved around the ward in a wheelchair when she was not on bed rest. How does this affect her edematous tissues?
Paper For Above instruction
Disorders of fluid and electrolyte balance are critical considerations in patients with eating disorders such as anorexia nervosa, as exemplified by Amanda’s case. Anorexia nervosa, characterized by significant weight loss and potential dehydration, disrupts normal fluid regulation and electrolyte homeostasis. This paper explores the key protein involved in edema formation, the mechanisms behind different types of edema, and the implications of immobility on edematous tissues.
Identification of the Protein: Serum Albumin
The nurse was likely referring to serum albumin, a predominant protein in plasma responsible for maintaining oncotic pressure. Albumin plays a vital role in keeping fluid within the blood vessels by exerting osmotic pull against the hydrostatic pressure exerted by blood flow (McKinney et al., 2020). In cases of malnutrition and protein deficiency, such as in Amanda’s anorexia nervosa, serum albumin levels tend to decline, leading to a decreased coloidal osmotic pressure (Harrison et al., 2018). Consequently, fluid tends to shift from the vascular compartment into the interstitial space, manifesting clinically as edema.
Contribution of Albumin Deficiency to Edema
A deficiency in serum albumin impairs the body's ability to retain fluid within the intravascular space, resulting in increased leakage of plasma into surrounding tissues. This process occurs because albumin helps maintain the balance of fluid distribution by exerting osmotic pressure. When albumin levels fall, the osmotic gradient diminishes, allowing excess fluid to escape capillaries and accumulate in tissues, causing swelling (Koufakis et al., 2019). This is particularly evident in severe malnutrition cases associated with anorexia nervosa where hypoalbuminemia is common. The resulting edema is often generalized but can be localized depending on the site and severity of protein deficiency.
Differences between Pitting and Nonpitting Edema
Pitting edema is characterized by an indentation or “pit” remaining after pressing the swollen area with a finger or thumb (Bishop & Robbins, 2021). This type of edema typically indicates an imbalance in fluid filtration and reabsorption in the interstitial space, often due to increased hydrostatic pressure or decreased plasma oncotic pressure. It is common in conditions like heart failure, nephrotic syndrome, and severe malnutrition (McKinney et al., 2020).
Nonpitting edema, on the other hand, does not leave an indentation after pressure application. It is caused by the accumulation of the lymphatic fluid or fibrosis within tissues, often associated with conditions such as lymphedema or myxedema in hypothyroidism (Walker & Smith, 2019). The tissue’s firmness and the absence of depression at the site differentiate nonpitting edema from pitting edema. These distinctions help clinicians diagnose the underlying causes of edema and determine appropriate treatment strategies.
Impact of Restricted Mobility on Edematous Tissues
Amanda’s limited mobility complicates her condition by impacting the distribution and resolution of edema. When patients are immobile or confined to bed, the normal physiological mechanisms promoting lymphatic and venous drainage are impaired. Gravity assists in circulating fluids and lymph away from extremities; when this process is hindered, edema tends to worsen, especially in dependent areas such as the lower limbs (Cesaroni et al., 2020).
Furthermore, immobility may contribute to skin breakdown due to persistent pressure on edematous tissues, increasing the risk of pressure ulcers. The accumulation of fluid in tissues stretches the skin and underlying tissues, reducing oxygen and nutrient delivery, thereby impairing wound healing. Mobilization and physical activity encourage lymphatic flow and help reduce edema, highlighting the importance of maintaining mobility in managing these patients (Kouba et al., 2021).
Conclusion
Amanda’s case underscores the importance of understanding the physiological mechanisms underlying edema and the impact of nutritional deficiencies. Serum albumin deficiency plays a central role in the development of edema in malnourished patients by reducing oncotic pressure, facilitating fluid shift into tissues. The distinction between pitting and nonpitting edema aids in diagnosis and guides treatment. Moreover, immobility exacerbates edema due to compromised lymphatic and venous drainage. Understanding these mechanisms enables better management of fluid-electrolyte disturbances, ultimately improving patient outcomes in disorders such as anorexia nervosa.
