Sleep Disorders And Fatigue

#Tired All The Time? | What Causes #Fatigue?

Symptoms: Chronic fatigue, feeling exhausted upon awakening, snoring

Sleep disorders are a group of conditions that disrupt or prevent restful, restorative sleep. That can take a toll on your health and quality of life, so its important to look out for signs and symptoms.


Sleep apnea is one of the most common sleep disorders. If you or your partner notices loud snoring and you wake up tired and stay that way, you could have sleep apnea. More than one-third of adults in the U.S. snore at least a few nights a week. But if the snoring stops your breathing for seconds at a time, it could be sleep apnea. Learn more about the best sleep positions and see if sleeping on your stomach is bad or not.

Obstructive sleep apnea causes low blood oxygen levels. That’s because blockages prevent air from getting to the lungs. The low oxygen levels also affect how well your heart and brain work. Sometimes, the only clue that you might have sleep apnea is chronic fatigue.

Your doctor may prescribe a medical device called CPAP that helps keep your airways open while you sleep. In severe cases of sleep apnea, surgery may help. The surgeon will remove tissues that are blocking the airways. If left untreated, sleep apnea can increase your risk of a stroke or heart attack.

But sleep apnea is just one of many sleep disorders that cause fatigue. Other common types include:


Too Much Or Too Little Activity

A person with fatigue may not feel able to exercise, and a lack of exercise can cause further fatigue. A lack of exercise may eventually cause deconditioning, making it harder and more tiring to perform a physical task.

Fatigue can also affect healthy individuals after prolonged, intense mental or physical activity.

Periodic Limb Movement Disorder

Though you are probably unaware of it, you may be involuntarily moving your legs during the night as you sleep. The movement may be significant enough to wake you. The interruptions in sleep may or may not wake you, but either way are significant enough to cause havoc in your sleep cycle. People with PLMD often complain of feeling unrested and of daytime sleepiness.

The cause of PLMD is unknown, but may be related to anemia, central nervous system problems or may be genetic. Good sleep hygiene habits will help relief PLMD. If you are not relieved despite having good sleep hygiene, a consultation with your health care provider is necessary.

Being Overweight Or Underweight

Overweight increases the risk of fatigue by increasing the risk of conditions that have fatigue as a common symptom, such as diabetes or sleep apnea.

Carrying more weight and experiencing joint or muscle pain can lead to or exacerbate fatigue.

Similarly, people with underweight may tire easily, depending on the cause of their condition. Eating disorders, cancer, chronic diseases, and an overactive thyroid can all cause weight loss, as well as excessive tiredness and fatigue.

Heart Disease And Fatigue

Why I Am Tired All The Time

Symptoms: Fatigue from an activity that should be easy

If youre exhausted after an activity that used to be easy — for example, walking up the steps — it may be time to talk to your doctor about the possibility of heart disease. Heart disease is the leading cause of death in women. If your fatigue is related to your heart, medication or treatments can usually help correct the problem, cut the fatigue, and restore your energy.

Whats Causing You To Be So Tired

Are being tired and feeling fatigued the same thing? Yes and no, says Dr. Ankerman.

In todays day and age, we use those terms interchangeably, which isnt correct, he says. Tiredness is something that is natural. You might be tired after a busy day at work or exercising. Thats normal and most people experience that.

On the other hand, fatigue is more intense than just being tired.

No matter how much you rest, or how little you do, you still have this feeling of not having a ton of energy or ability to do much, says Dr. Ankerman. It can sometimes be a sign of something more serious going on.

So what might be causing you to be tired or feel fatigued? Here are a few reasons.

Not Eating Enough Calories

Consuming too few calories can cause feelings of exhaustion.

Calories are units of energy found in food. Your body uses them to move and fuel processes like breathing and maintaining a constant body temperature.

When you eat too few calories, your metabolism slows down in order to conserve energy, potentially causing fatigue.

Your body can function within a range of calories depending on your weight, height, age and other factors.

However, most people require a minimum of 1,200 calories per day to prevent a metabolic slowdown.

Experts on aging believe that although metabolism decreases with age, older people may need to eat at the top of their calorie range in order to perform normal functions without becoming fatigued .

In addition, its difficult to meet your vitamin and mineral needs when calorie intake is too low. Not getting enough vitamin D, iron and other important nutrients can also lead to fatigue.

In order to keep your energy levels up, avoid drastic cuts in calorie intake, even if your goal is weight loss. You can calculate your calorie needs using the calorie calculator in this article.

What Is Excessive Sleepiness

Although excessive sleepiness overlaps with fatigue, it is a distinctly different symptom. When a person experiences excessive sleepiness, they tend to nod off or fall asleep when they want to be awake. When a person experiences fatigue, they often feel tired but do not usually fall asleep when they want to be awake.

Excessive sleepiness is often referred to as excessive daytime sleepiness, or EDS, by physicians and sleep specialists. To eliminate or reduce your EDS, you must first figure out why you are experiencing it.

Too Much Alcohol Or Caffeine

While drinking alcohol may help you to fall asleep at first, it actually disrupts your sleep by causing you to wake up more frequently during the night. Avoiding caffeine within 4 to 6 hours of your bedtime will help you to sleep better. Adjusting your alcohol and caffeine intake may help to reduce your consistent fatigue.

Bacterial Or Viral Infection

You have a cold or the flu. Youre feeling worn down and tired. Thats because your body is fighting the infection and its putting a strain on your immune system.

More serious bacterial and viral infections can interact with different organ systems which can cause fatigue, says Dr. Ankerman.

Infections like mononucleosis and COVID-19 can even cause long-lasting tiredness.

Shift work can wreak havoc on your body’s 24-hour internal clock, or circadian rhythm. When you work nights or rotate shifts, your body doesn’t know when to be awake and when to sleep, which causes fatigue.

Daylight is often a cue to be awake. If you must sleep during the day, try to make your sleeping area as dark, cool, and quiet as possible. If you must work at night, keep your workplace brightly lit. Try to work night shifts all in a row and avoid frequently rotating shifts. Stay away from caffeine, and stick to a regular sleep-wake schedule as much as possible on days off.

Diseases That Have Fatigue As The Main Symptom

When your immune system is grappling with a disease, that fight requires energy. So it’s probably not surprising that almost any disease you can name has fatigue listed among its symptoms.

“Fatigue may be the most common symptom people report, and in and of itself it can’t point you toward a diagnosis,” says Roxanne Sukol, MD, a preventive medicine specialist at Cleveland Clinic.

Also complicating matters: “There are so many different ways to measure fatigue,” says Anne Cappola, MD, of the University of Pennsylvania’s Division of Endocrinology, Diabetes, and Metabolism. “Does it mean you’re sleeping more? Or can’t exercise as long as you used to? Or don’t have energy at the end of the day?”

Fatigue comes in different flavors. “There’s physical fatigue, but also emotional fatigue and psychological fatigue,” she says. “People underestimate the effects of psychological stress on energy levels, but in retrospect, after that stress is gone, they realize that was making them so tired.”

Whenever a patient sees Cappola for fatigue, she says she talks with them about reasonable expectations. “Our society builds this belief that you should be on the run all the time, but that’s not sustainable for many of us,” she says. “If your schedule’s changed or you haven’t been sleeping enough or something else is going on, feeling tired is natural.”

  • You have no desire to do things you love because youre tired.

  • stiff, achy, or weak muscles
  • feeling uncomfortable or uneasy
  • sleep that is disturbed or nonrestorative
