Subjective global assessment (SGA) is a nutritional evaluation method used to assess the nutritional status of patients. It is a widely recognized and commonly employed tool that considers four key entities: (1) weight loss; (2) presence of fluid retention; (3) diminished muscle mass; and (4) subcutaneous fat loss.

The Subjective Global Assessment (SGA) is a tool used to assess the nutritional status of patients. It is a simple, quick, and inexpensive way to screen for malnutrition and to monitor the effectiveness of nutritional interventions.
The SGA is based on three questions:
- Has the patient lost weight in the past 6 months?
- Does the patient have any gastrointestinal symptoms?
- Is the patient taking any medications that could affect their nutritional status?
The answers to these questions are used to calculate a score of 0-10. A score of 0 indicates normal nutritional status, while a score of 10 indicates severe malnutrition.
The SGA is a valuable tool for assessing the nutritional status of patients. It is simple to use and can be used in a variety of settings.
Here are some tips for using the SGA:
- Ask the patient the questions in a clear and concise manner.
- Be sure to explain the purpose of the assessment to the patient.
- Use the patient’s responses to calculate a score of 0-10.
- Interpret the score according to the following table:
| Score | Nutritional Status |
|---|---|
| 0-3 | Normal |
| 4-6 | Mild malnutrition |
| 7-9 | Moderate malnutrition |
| 10 | Severe malnutrition |
- Use the SGA to monitor the effectiveness of nutritional interventions.
The SGA is a valuable tool for assessing the nutritional status of patients. It is simple to use and can be used in a variety of settings. By following these tips, you can ensure that you are using the SGA correctly.
Question 1:

Question 3:
What are the limitations of subjective global assessment?
Answer:
SGA is a subjective measure, which means that it can be influenced by the clinician’s experience and bias. Additionally, SGA does not provide specific information about the cause of malnutrition.
