Signs and Symptoms are two important terms used in medical science to describe the physical and subjective manifestations of a disease or a medical condition. Signs refer to objective findings that can be observed or measured by a healthcare provider, while symptoms are subjective experiences reported by the patient.
What are Signs and Symptoms?
Signs are physical or objective findings that can be observed or measured by a healthcare provider during a medical examination or test. Symptoms, on the other hand, are subjective experiences reported by the patient, such as pain, fatigue, or nausea.
Types of Signs and Symptoms:
Signs and symptoms can be further classified into various types based on their nature and origin. Some of the common types include:
- Acute: Signs or symptoms that appear suddenly and are usually severe
- Chronic: Signs or symptoms that persist for a long time, usually more than three months
- Local: Signs or symptoms that affect a specific part of the body
- Systemic: Signs or symptoms that affect the entire body or multiple systems
- Primary: Signs or symptoms that are directly related to the disease or condition
- Secondary: Signs or symptoms that result from the disease or condition, but are not directly related to it

- Elevated temperature or fever

Difference Between Signs And Symptoms
Signs |
Symptoms |
| Objective measurements of a medical condition | Subjective experiences of a medical condition |
| Can be observed or measured by a healthcare provider | Are reported by the patient or their caregiver |
| May be visible, such as a rash or swelling | Can be internal, such as pain or fatigue |

| Can be used to diagnose a medical condition | Are used to help diagnose a medical condition |
Conclusion
In summary, signs and symptoms are important concepts in medical science that describe the physical and subjective manifestations of a disease or condition. While signs are objective findings that can be observed or measured by a healthcare provider, symptoms are subjective experiences reported by the patient. Both signs and symptoms play a crucial role in the diagnosis and treatment of medical conditions.
