What is the difference between fatigue and lethargy?

While fatigue and lethargy are often used interchangeably, the two states aren’t exactly the same.

Fatigue is a persistent and constant feeling of extreme tiredness, sleepiness, or exhaustion.

Lethargy is more focused on the low energy a person has.

People who experience fatigue typically feel lethargy, or lack of energy, as part of being fatigued.

It may be difficult to tell whether a baby is lethargic or just drowsy from sleeping.

It can also be a side effect of medication or the bodys response to alcohol.

Consumption of alcohol while taking certain medications can also cause a person to feel lethargic.

It is often resolved by getting enough sleep, maintaining a healthy diet, andmanaging stress.

When lethargy is determined to be due to an underlying condition, treatment is aimed at the cause.

Diagnosis

The first step in determining the cause of lethargy is to see a healthcare provider.

They will take your medical history, ask about your symptoms, and perform a physical exam.

When to See a Healthcare Provider

Lethargy is rarely a medical emergency.

However, it can become one if it is accompanied by other serious symptoms.

It is a state of being exhausted, with little to no energy, and it tends to linger.

Treatment depends on the underlying cause.
