No Energy, Lack of Stamina and Tired
Work overload can cause feelings of fatigue.

Being tired and having lack of stamina and energy can be a healthy response to emotional or physical exhaustion. If you know what is causing you to feel worn out you may be able to fix the problem with a few simple tweaks to your daily habits. However, such symptoms may also signify an underlying health problem that should receive medical attention.

Fatigue vs. Drowsiness

You may be able to narrow down the potential culprits of your current condition if you’re able to specify your symptoms. Fatigue and drowsiness may seem like the same condition, but they have two separate definitions. Fatigue involves a lack of physical energy and motivation, whereas drowsiness involves a constant need to sleep, according to the University of Maryland Medical Center. You may, however, experience both fatigue and drowsiness simultaneously.

Physical Causes

Many cases of tiredness, lack of stamina and dwindling energy can be linked to lifestyle factors such as sedentary lifestyle, use of caffeine and alcohol, use of narcotics, excessive physical activity, sleep deprivation and poor eating habits, according to However, physical conditions such as nutritional deficiencies, cancer, underactive or overactive thyroid, obesity, pregnancy, diabetes, allergies and persistent pain can also cause the body to feel worn down. Additionally, medications such as allergy pills and pain relievers can lead to similar symptoms.

Psychological Causes

Feeling mentally worn down also can lead to feelings of fatigue and drowsiness. Your body may go into “shut down” mode if you have recently been dealing with depression, grief, anxiety or stress. Alternately, feeling bored with your current state of affairs can cause you to experience similar symptoms.

Lifestyle Changes

Make a few healthful changes in your life, if necessary, and you may need no extra medical attention to treat your current symptoms. Get at least seven to eight hours of sleep every night, eat a well-balanced diet that involves primarily plant-based foods, drink at least eight 8 oz. glasses of water per day, exercise at least 30 minutes a day and avoid use of alcohol, drugs and nicotine, recommends MedlinePlus. Additionally, find ways to decompress. Try taking a yoga class or downloading an MP3 on guided meditation and eliminate life stressors that can be changed. For example, end a stressful relationship or switch jobs.

When to Seek Help

Get in touch with your doctor if your symptoms persist for at least two weeks despite your attempts to sleep more, improve your diet, exercise and de-stress. Get medical help as soon as possible if your fatigue or drowsiness is accompanied by dizziness, blurred vision, swelling and weight gain, little to no urine output, abnormal bleeding, headache, feelings of confusion, or pain in the back, pelvis or abdomen, recommends Call 911 if your symptoms are accompanied by chest pain, irregular or speedy heartbeat, shortness of breath or thoughts and concerns about harming yourself or others.
