Some conditions that cause fatigue include thyroid disorders, iron deficiency anemia, diabetes, chronic fatigue syndrome, and COVID-19. Some other causes of fatigue may involve your diet, sleep, and levels of stress. Lifestyle changes can often improve feelings of fatigue in these situations.
Iron deficiency (anemia)
Hormonal and lifestyle differences like pregnancy, menstruation, and menopause mean that women need more iron than men in their diet, but few women actually get as much as they need. The result—anemia's—most common symptoms include fatigue and weakness.
One possible reason for feeling tired, anxious, and weak is having low levels of iron, vitamin D, or B12. Many experts believe that a significant percentage of the U.S. population is deficient in vitamin D. Having low levels of vitamin D can cause muscle weakness and pain.
Medical causes – unrelenting exhaustion may be a sign of an underlying illness, such as a thyroid disorder, heart disease or diabetes. Lifestyle-related causes – alcohol or drugs or lack of regular exercise can lead to feelings of fatigue. Workplace-related causes – workplace stress can lead to feelings of fatigue.
Most of the time fatigue can be traced to one or more lifestyle issues, such as poor sleep habits or lack of exercise. Fatigue can be caused by a medicine or linked to depression. Sometimes fatigue is a symptom of an illness that needs treatment.
Mental laziness and lack of motivation can also be caused by one simple problem: not having enough exercise and nutrients in the body. One should consider eating healthy food high in protein, such as green, leafy vegetables, and fatty fish. Research also suggests eating berries and walnuts and drinking coffee or tea.
There are three types of fatigue: transient, cumulative, and circadian: Transient fatigue is acute fatigue brought on by extreme sleep restriction or extended hours awake within 1 or 2 days.
If you have been feeling constantly tired for more than 4 weeks, it's a good idea to see your GP so they can confirm or rule out a medical condition that could be causing your tiredness.
If the fatigue is associated with chest pain, shortness of breath, irregular heart rate, or sense of imminent passing out, these are urgent conditions that warrant immediate medical attention. These could be symptoms of a serious heart condition or major vascular insufficiency.
Note: There is no blood test to diagnose chronic fatigue syndrome. However, this test may provide proactive insight into chemical or functional imbalances that can contribute to extreme fatigue.
1. Vitamin B12. Vitamin B12 is essential to the body's metabolic process. This vitamin maintains blood and nerve cells, makes DNA, supports brain function, and helps the body convert food into energy.
Melatonin
Serotonin is a neurotransmitter which can be converted into melatonin, a natural hormone, in the pineal gland. Both of these hormones play a key role in sleep. Melatonin is produced at night and it plays a key role in adjusting your body clock.
Most likely, you're still tired after 8 hours of sleep because you don't know your sleep need, you're getting less sleep than you think, you've got sleep debt, or you're out of sync with your circadian rhythm.
By the age of 80, cerebral blood flow is approximately 20% less than at age 30, which means that the heart has less capacity for physical exertion and may feel fatigued more easily. As a result, we feel a gradual decline in our energy and endurance levels.
Many people with diabetes will describe themselves as feeling tired, lethargic or fatigued at times. It could be a result of stress, hard work or a lack of a decent night's sleep but it could also be related to having too high or too low blood glucose levels.
Common underlying issues that can make you feel tired after waking up and persist throughout your day include sleep inertia, sleep disorders, bright light exposure, and a poor bedroom environment, to name a few.
Treatment Options
Studies show that psychological support, including cognitive behavioral therapy, can help treat symptoms of chronic fatigue syndrome. Although there is no cure, physicians may treat symptoms with medications, such as antidepressants and anti-anxiety drugs.
Hypersomnia means excessive sleepiness. There are many different causes, the most common in our society being inadequate sleep. This may be due to shiftwork, family demands (such as a new baby), study or social life. Other causes include sleep disorders, medication, and medical and psychiatric illnesses.
It's called sleep inertia: "The transitional state between sleep and wake, marked by impaired performance … and a desire to return to sleep." The main thing to know about sleep inertia is it is completely normal.
Low motivation can be a common symptom of depression, anxiety, and other mental health issues. You can practice self-help and self-care as much as you can, but you may find that seeking professional help is more helpful for your emotions. Online therapy is beneficial, especially during the COVID-19 pandemic.
Magnesium helps to reduce fatigue and exhaustion. The mineral plays an important role in maintaining normal nervous system activity. A magnesium deficiency can interfere with the transmission of nerve impulses. It may also reduce circulation.
So does vitamin B12 give you energy? While B12 doesn't directly provide energy, it does give the body the tools it needs to convert food molecules into energy. Getting the recommended daily amount of B12 can therefore help ensure that the body is able to make the energy it needs to do everything you need it to do.
