Fatigue is a major, common complaint. It is a symptom of numerous conditions. The health issues that are associated with this problem are estimated at well over 200. It is not only a symptom of medical issues, but may also be a risk factor.
So, by asking what causes fatigue, you shouldn't expect a straightforward answer. Detecting the particular culprit may involve a bit of trial and error since there are so many possible ones. In this article, you can find information on the more common causes of fatigue.
Fatigue is simply a feeling of being tired or exhausted. It results from insufficient energy or strength to carry out regular daily tasks. Some patients often have a bit of difficulty with the choice of words to describe the feeling. Words like tiredness, exhaustion, or lethargy are commonly used.
However, some experts have made a distinction between tiredness and fatigue. They say everyone experiences the former, which a person can relieve by rest or sleep. But fatigue is usually not relieved by rest or sleep and involves greater feeling of tiredness.
Fatigue can be physical or mental in nature. Its symptoms include:
In the following sections, we discuss some of the common causes of fatigue.
This is a major reason why many people experience fatigue. When you sleep well, your body gets opportunity to be refreshed and rejuvenated. You put your health at risk if you are the type that skimps on sleep.
Many people are actually failing in this regard, which is why there is increasing complaints about fatigue. Ideally, an average adult needs between 7 and 8 hours of sleep daily. A significant number of people in the United States do not get that much. A Centers for Disease Control and Prevention estimate has it that more than 30 percent of Americans do not sleep enough.
People take caffeine to stay alert and active. A very popular source is coffee. Considering the purpose of use, it may sound strange that this stimulant can also contribute to fatigue.
When the effects of caffeine wear off, you may feel so burned out. The psychoactive drug can interfere with your sleep, making you feel less refreshed or outright tired the day after.
Iron deficiency anemia ranks among the most common causes of fatigue. This condition is characterized by low levels of red blood cells, a major component of which is iron. With lower red blood cells and iron, less oxygen is available in the body. This makes you feel tired.
Anemia is especially a major cause of fatigue among women. The pregnant ones and those with heavy menstrual periods are at a greater risk.
However, too much iron in the body can also be a risk factor in people aged 30-60 years. This rare, genetic disorder is known as hemochromatosis.
Many people who experience this scary disorder do not know, let alone suspecting it being responsible for their fatigue. Sleep apnea is a condition characterized by narrowing or closing of the throat during sleep. It involves repeated, brief interruptions in breathing.
This sleeping disorder causes loud snoring and decline in oxygen levels in the blood. It can result in sleep interruptions. When you combine that with low blood oxygen levels, you can easily see why this can cause fatigue.
Sleep apnea is particularly common among middle-aged men who are overweight or obese. The risk is higher with smoking or alcohol intake.
Your eating habits can also be a factor as to whether you'll have fatigue problem. Junk foods, such as processed foods and those with refined sugars, can make you feel so tired.
If you do not provide your body with the right foods at the right time, you will very likely suffer lack of energy. That's easily understandable, actually. This may be the reason you're always feeling tired, if you're the type that skip meals, especially breakfast.
This serious autoimmune disorder is a major reason why many people are more careful about consuming gluten-rich foods. Celiac disease, a condition that affects an estimated 1 in 100 persons worldwide, is the result of an individual's immune system reacting to gluten.
Strangely, just like sleep apnea, many people with the disorder are not aware of it. Fatigue is just one of the symptoms patients may exhibit. Celiac disease can also result in anemia, diarrhea, and unintentional weight loss.
Restless legs syndrome (RLS) is a relatively rare condition that can produce fatigue as a symptom. As a result of discomfort, patients experience an irresistible urge to move their legs. This typically happens in the evenings.
The constant urge to move the legs can impact adversely on the quality of sleep. It can keep you up for most of the night, making you feel tired or less active the day after.
An underactive thyroid gland is responsible for fatigue in some people. The consequence of this is reduction in the levels of thyroid hormone in the body. Since this is crucial for energy production, you tend to feel tired easily when you have too little.
Hypothyroidism is more of an issue among older individuals and women. Weight gain is another common problem that can arise from this disorder.
From the name, one can easily see why this is a problem. Chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME), describes persistent fatigue that doesn't seem to have a visible cause.
You should suspect CFS if your feeling of fatigue is disabling and makes it hard to do daily activities. The sensation must have also been on for at least 4-6 months.
Mental health issues contribute to feeling of fatigue. Notable among this is depression.
This disorder not only causes feeling of deep sadness, but can also drain you of energy. Depression can interfere with your sleep cycle, making it hard to fall asleep or causing you to wake too early. Of course, this can leave you less refreshed and feeling tired.
Anxiety and depression typically go hand in hand. If you find yourself constantly feeling anxious, you will often feel fatigued. This is what medical experts often describe as generalized anxiety disorder (GAD).
People with GAD typically find it more tasking doing daily activities. They also tend to be more easily irritable.
Women are said to be at a higher risk of experiencing fatigue as a result of anxiety.
Excessively high amounts of sugar in the body are not ideal for health. This is why diabetics are typically advised to keep close watch on their glucose levels. Fatigue is just one of the problems that people with diabetes may experience.
At normal levels, sugar in the blood is effectively used for energy production in healthy humans. But when the levels are too high than the body can process, feeling of tiredness can result.
It should be noted, though, that too little sugar in blood can mean too little energy as well.
Fatigue is one of the signs that may point to the existence of this life threatening condition. Heart disease is usually synonymous with circulation issues.
When the heart is not able to effectively pump blood around the body, there is reduction in levels of oxygen. This can make simple things, such as walking or climbing stairs, rather tough to do.
Certain medications can result in feeling of fatigue. Among such are non-steroidal anti-inflammatory drugs (NSAIDs). Antidepressants, sedatives, statins, antihistamines, and medications for treating hypertension can also lead to drowsiness and fatigue.
As we already noted, the list of conditions that can make you feel tired is a long one. It includes the following issues:
What is evident is that a doctor will be needed in most cases to identify the cause of fatigue. Even at that, it may still be somewhat difficult detecting the particular cause. Blood, urine and imaging tests are often necessary to make a diagnosis.
There are different approaches for treating fatigue, depending on the particular cause. Regular exercise, a healthy diet, and restful sleep are typically among recommendations.
It is thought that growth hormone is beneficial for treatment of people with chronic fatigue syndrome. This is partly because some symptoms of HGH deficiency are similar to those seen in the disorder. People with CFS usually experience generalized suppression in their hypothalamic pituitary adrenal axis.
Growth hormone doesn't always help, but can help improve sleep quality. If you wish to try all the same, it may be better to take an HGH supplement like Genf20 Plus or Genfx for this purpose. There are reports of synthetic HGH users feeling fatigued or sleepy following injections.
