Low Energy - Is It A Serious Health Problem?

Low Energy - Is It A Serious Health Problem?

Low Energy Signs and Symptoms

Most everyone experiences low energy levels from time to time. Feeling tired or physically or mentally drained is an entirely reasonable response to intense activity, lack of sleep, and stress. For many people, however, energy levels do not improve with adequate relaxation. In these situations, low energy may be caused by an underlying condition.

Underlying Conditions

Low energy levels cause one to feel lethargic or fatigued. While it is usually completely normal, chronic low energy may be caused by a larger health condition. Countless conditions can cause low energy in people of all ages, but some are more common than others. Some of the most common causes include malnutrition, chronic fatigue syndrome, low blood pressure, and anemia. Problems with the thyroid may also be to blame for a general lack of energy. Also, sleep disorders, allergies, and asthma can make patients feel tired no matter how much rest they get.

When to See a Doctor

In rarer cases, low energy may be caused by more serious underlying health problems such as heart problems or even cancer. Depression or drug or alcohol abuse can also cause it. As a result, it is important to see a doctor when dealing with chronic low energy levels that do not improve with adequate rest and proper nutrition.

Diagnosing Low Energy

Doctors may use many techniques when trying to determine what is making a patient feel a general lack of energy. Some problems can be diagnosed based upon the exact symptoms the patient is experiencing. Others require additional testing. Blood tests are commonly used to detect hormone imbalances caused by thyroid problems or some deficiencies that can be caused by malnutrition. Blood tests can also detect things like low iron levels that may cause patients to feel tired.

Life Style Changes vs. Surgical Intervention

When underlying conditions are detected and treated, symptoms like low energy tend to subside. As a result, treating the symptom relies on correctly addressing the underlying cause. Many problems may be treatable through lifestyle changes, dietary supplements, or prescription medications. Some problems, however, may require surgical intervention.


 Low energy in itself usually is not a serious concern. The underlying problem, however, should be addressed. When left untreated, an underlying condition may progress, and the patient's energy levels may continue to decline. In extreme cases, low energy can have a negative impact on one's day to day life. With treatment, most patients can restore previous energy levels.
