Symptom

What Is a Symptom?

A symptom is defined as a physical or mental factor that indicates a condition or disease. While the words symptom and sign are sometimes used interchangeably, there are differences between the two. The most noticeable difference is determined by who is observing it. Typically, when a patient notices something it is a symptom. When a doctor notices something it is a sign.

Symptom vs. Sign

A symptom is considered to be subjective evidence of a condition or disease. This means that a symptom is something experienced by the individual with the disease or condition. A sign is something that is identified by another person, such as a medical professional. Both symptoms and signs are used to determine the possible diagnosis of the condition or disease affecting the individual.

Types

There are three distinct categories of symptoms. These include:

Chronic Symptoms: These are long lasting symptoms. Chronic symptoms can also be recurring. They are common in conditions such as cancer, asthma, and diabetes.

Relapsing Symptoms: These are symptoms that happened in the past, went away, and then came back. Relapsing symptoms can occur in conditions such as depression, anxiety, cancer, multiple sclerosis, and others.

Remitting Symptoms: These are symptoms that improve and often go completely away.

General symptoms are those that are related to the effects of a certain condition. For example, fever is a symptom of influenza, anorexia is a symptom of an eating disorder, and fatigue, sweating, and seizures are symptoms of drug or alcohol withdrawal.

There are also symptoms that are non-specific and do not indicate a disease or serious underlying medical or psychological condition. For example, fatigue can be a symptom of disease, but is also considered normal and experienced by most everyone after a particularly strenuous day or time period.

There are also certain diseases and conditions where there are no symptoms present. These are known as asymptomatic conditions or diseases. An example of this is hypertension (high blood pressure), where a patient does not feel any symptoms associated with their condition.

An asymptomatic infection is where a person may not develop any symptoms until well after the infection has incubated. Also known as subclinical infection, an asymptomatic infection is common in diseases such as HIV. HPV is another example of a subclinical infection that can incubate, then later cause cervical cancer or genital warts.

Causes

Symptoms are caused by whatever the underlying condition is that is making a person experience them. Some symptoms are fairly common in several different diseases and conditions, while other symptoms are more specific to a single cause.
