Routine Hospital Diets

Routine hospital diets, also known as standard or regular diets, are designed to meet the general nutritional needs of patients while considering their medical condition, age, activity level, and personal preferences. The primary goal of hospital diets is to provide adequate nutrition to support recovery, manage health conditions, and promote well-being. These diets are typically prescribed by healthcare professionals such as dietitians or physicians based on the patient’s nutritional requirements and health status.

Classification of Routine Hospital Diets

Routine hospital diets are typically classified into the following categories based on their consistency, nutritional content, and therapeutic purpose:

  1. Regular Diet
  2. Soft Diet
  3. Full Liquid Diet
  4. Clear Liquid Diet
  5. Therapeutic Diets

Renal disorders, also known as kidney diseases, encompass a wide range of conditions that affect the function of the kidneys, including chronic kidney disease (CKD), acute kidney injury (AKI), nephrotic syndrome, glomerulonephritis, and end-stage renal disease (ESRD). The primary role of the kidneys is to filter waste products from the blood, regulate electrolyte balance, and maintain fluid homeostasis. When kidney function is impaired, waste products and excess nutrients can accumulate in the blood, leading to various health complications.

The therapeutic diet for renal disorders aims to:

  1. Minimize the accumulation of waste products and toxins.
  2. Maintain electrolyte and fluid balance.
  3. Slow the progression of kidney disease.
  4. Prevent complications like hyperkalemia, hyperphosphatemia, and hypertension.
  5. Provide adequate nutrition to support overall health and well-being.

The following therapeutic diets are tailored to meet the needs of individuals with specific renal disorders:

1. Chronic Kidney Disease (CKD)

Definition:
