11 Medical Reasons Why You Are Feeling Tired And Fatigued All The Time

If you feel that the “sprite” inside you has gone away and left you weary and tired, then you must look into the underlying reason: your deteriorated health.

This lack of energy and vigor may be due to everyday complaints like insufficient sleep hours, jet lag, intense physical and mental activity, adverse effects of medicaments or a nutrient-poor diet. In contrast to these reasons for tiredness, the underlying reasons for unremitting exhaustion can be much deeper. This condition is not equal to drowsiness although they look like the same thing.

These are the 11 most common medical reasons responsible for your unrelenting fatigue and exhaustion:

1. CFS

The CFS  or Chronic Fatigue Syndrome is characterized by acute fatigue that can hold you for months. If you are misfortunate enough to have CFS then, unlike other people, you will be literally “knocked down” after body activities that are considered normal and leave other people slightly-to-moderately tired.

The medical statistics says that these ‘bouts of extreme fatigue’ can last longer than 24 hours following the physical or mental effort making you bed-ridden. Reports state that this condition sometimes wouldn’t go away even after you give it a long rest time!

The CFS gets exacerbated when patients also complain of having splitting headaches, sore throat, and pains in muscles or joints. In the medicals accounts, no uniformed cause of CFS has been established as yet.

According to some researchers, contributing factors to this syndrome are: viruses, lasting low blood pressure, slackened immune system and hormonal imbalances. The treatment options for the chronic fatigue syndrome are better self-care based on medical advice and spending some time in a rehabilitating under medical supervision.

An Oxford University research team working within King’s College London and Queen Mary University of London, in their 2015 study suggest 2 potential treatments for CFS with the best aftermaths after the ‘fatigue battle.’ Namely, they found that cognitive behavioral therapy and/or graded exercise therapy are best treatment courses for people suffering from CFS.

2. Deficiency of red blood cells

The deficiency of red blood cells or of hemoglobin in the blood is medically termed anemia. The hemoglobin is a red protein in charge of transporting oxygen in the blood of vertebrates. Its molecule comprises 4 subunits, each containing an iron atom bound to a heme group. Since in the anemia is involved this very important protein that is lack of oxygen in the body, the condition is marked by striking face pallor and body weariness.

The so-called cause and consequence relationship has been shown between anemia and fatigue in a 2002 study, published in the chronicles of Seminars in Oncology. Besides fatigue, the anemia is recognized by shortness of patient’s breath, vertigo, cool sensation in the limbs, headaches, pale skin and pain in the chest area. Whether you are or you are not anemic is determined by a blood checkup. Anemia is a serious condition although it is not life-threatening at the beginning. So, timely diagnosis and management of the condition are advised for one’s good health.

3. Hypothyroidism


The medical condition of hypothyroidism occurs when one’s thyroid gland becomes underactive. This small-in size but important gland helps in metabolism regulation. If the gland becomes underactive, it is not producing enough thyroid hormones, which results in debilitating fatigue and weariness without extreme activity of the body. A study of 2012, released in the European Journal of Endocrinology, found that patients with autoimmune hypothyroidism were even more fatigue-prone than patients with differentiated carcinoma of the thyroid gland.

Like with anemia, hypothyroidism patients experience other symptoms as well – overweightness, sore muscle, hair loss, bad skin quality and stronger cold sensitivity. These symptoms can be treated by your doctor, so pay him a visit before they become a more serious ailment. And just like with anemia, an underactive thyroid condition can be easily diagnosed if you take a blood test.

4. Diabetes mellitus

The medical condition termed diabetes describes a group of metabolic diseases in which the person has high blood glucose. A 2014 study, posted in Diabetes Care, stated that Type 1 diabetes patients are the most chronic fatigue-stricken group. The study does not focus on the reason why diabetes makes people so tired and disabled for their daily routines.

Nonetheless, it is very logical that the human body depletes its energy when dealing with sudden changes in the sugar in the blood, thus making it fatigued.  For medical experts it is very intriguing why this condition appears even though the individual eats and sleeps regularly.

Other symptoms for the diabetic complaint are: greater-than-usual thirst and hunger, dry mouth, frequent urination, and weight shedding. Get yourself a clinical checkup as early diagnosis goes hand-in-hand with better outcome.

5. Fibromyalgia


Your body is your temple and you should know what resides in it. Chronic weariness [or musculoskeletal pain] is also associated with fibromyalgia, with women being its “special target.” Medically, it is listed as muscles, joints and fibrous tissues disorder. Although this condition does not make great physical damage to people having it, yet it is accompanied by depressive moods, social withdrawal and anxiety.

A 2013 study, proceeded in Arthritis Research and Therapy, found that fibromyalgia, among other discomforts, commonly produces fatigue as well.

So far, this condition has received smaller focus than chronic body pain, so results are yet to be confirmed. It is good to know that physical signals of fibromyalgia include: deep-seated muscle pain, tender and painful points in the body, sleep problems, depression and anxiety.

If you think these symptoms are troubling you, consult a medical doctor.  This condition could worsen in the course of time if unattended, so take the time to thoroughly examine it.

6. MS or multiple sclerosis

The autoimmune disease – multiple sclerosis affects the central nervous system, more precisely the brain and the spinal cord. In this medical instance, the insulating coating around nerve cells (called myelin) gets ‘mistakenly attacked’ by the body’s own immune system. Like with fibromyalgia, the disease seems more common in the female population than in the male one.

The National Multiple Sclerosis Society stipulates that 80% of MS patients suffer from chronic fatigue. It also points out that fatigue is exacerbated as the day draws on, especially when heat and humidity are in the air. The Brazilian Journal of Medical and Biological Research published a study in 2008 reporting that the so-called restless legs syndrome, poor snoozing and daytime-felt fatigue are all usual in MS patients.

In support to these study findings, a 2014 study in the Journal of Clinical Sleep Medicine reports that bedtime troubles, in particular the obstructive sleep apnea, may be highly present. However, they are underestimated contributors to fatigue in patients with multiple sclerosis (MS). Multiple sclerosis is such a difficult condition as it also involves numbness in hands and feet, tingling pain in different points of the body, wooziness and slurred speech.

Unfortunately, this disease is considered incurable to present day. As with many other aggravating conditions, timely diagnosis and treatment effectively slow down the progression of the disease and decrease the acuteness of the symptoms.

7. The state of depression


The major depressive disorder or clinical depression is a common-but-serious mood disorder. As such, it can render a person feeling extremely worn-out, even after a long night’s sleep. Depressive people are often bothered with sleep disturbances, and it certainly affects their daytime energy level.

The World Health Organization’s estimate is that over 350 million people suffer from depression while feeling fatigued at the same time. Plus, Psychiatry published a study in 2004 in support of this announcement. The explanation says that “depression triggers a lower production of various neurotransmitters” and creates chronic fatigue.

8. Sleep apnea


Daylight fatigue and tiredness are also contributed to the sleep apnea. It is a type of a sleep disorder when a person’s normal continuous breathing is interrupted [or even stopped!] involuntarily in the sleep. When the path of air in the nose, mouth or throat is somehow narrowed or blocked people start suffering from the sleep apnea.

Chest published a study in the year of 2000 reporting that tiredness and lack of energy may be as important to patients suffering from obstructive sleep apnea. Indeed, the feeling of exhaustion [instead of restfulness], a headache upon waking up and snoring while sleeping indicate the condition of (obstructive) sleep apnea. The advice is to seek a medical attention as all types of sleep deprivation can harm your disposition in the long run.

9. Women in menopause

When going through their middle-age menopause, women commonly feel annoyed and tired. Thyroid and adrenal hormones, as well as estrogen and progesterone levels, all take part in the regulating of cellular energy in premenopausal women. It is so as the hormone levels in this period of woman’s life fluctuate a lot, and bring about tiredness.

When in menopause, women are ‘overwhelmed’ with night sweats and  hot flashes, so bad sleep quality can make them “saggy” during the day. The other known menopausal signs are anxiety, low concentration, and a lack of self-esteem. The chronic fatigue syndrome is a commonplace in cases of early menopausal women in their 40s, endometriosis, pain in the pelvic area, hysterectomy, and other uterus abnormalities, according to Menopause’s study of 2015. At this point, it’s important to get help and manage your symptoms. You don’t even have to leave the house, you can video chat with a menopause practitioner or browse the web for alternative solutions.

10. Glandular fever


Infectious mononucleosis (or glandular fever ) is a viral infection that is an underlying cause of severe weakness. Other symptoms of glandular fever are as follows: aching throat, aching muscles, low appetite, feverishness, and swollen glands. If these accompanying symptoms of glandular fever stop in a month, patients continue to feel fatigued for several months.

The Journal of Infectious Disease published a study in 2007 reporting that risk of a lengthened fatigue or chronic fatigue syndrome in glandular fever instances is 5-6 times more frequent than common upper-respiratory tract infections.

One more study of 2011, related in Psychological Medicines, also reported chronic fatigue syndrome after an acute glandular fever. See your family doctor for accurate diagnosis and treatment if you suspect that you (or your family member) have the symptoms of glandular fever.

11. Last but not least, poor, nutrient-deficient diet


Although diet is not defined as a medical condition, it may be the underlying reason for your severe fatigue and lack of “get-up-and-go.” It is important to have vitamin-and-mineral rich diet, not one saturated with fats and processed foods.  Also, pay close attention to get the nutrients your needs from plant-based meals and dishes as they promote lasting health and well-being.
