Chronic fatigue is a common symptom that involves lacking in the strength needed to perform activities that require physical or mental effort.
It can be moderate or intense, depending on its cause and the physical capacity the patient has to handle it.
Those who lead a sedentary lifestyle, especially those who suffer from obesity, can experience discomfort more severely, even by simply going for a walk.
However, regardless of this, there are other factors that can trigger fatigue even if you are in physically fit.
In this article, we want to explain 6 possible causes of chronic fatigue so that you’ll be able to identify them if you consistently suffer from this problem.
Hypothyroidism is a condition that occurs when the thyroid gland doesn’t produce enough hormones to regulate the body’s metabolism.
It’s one of the most frequent causes of tiredness and it makes you feel weak and discouraged even when resting.
There are two key components that lead us to suspect that this symptom is related to alteration of the thyroid function:
- The patient doesn’t feel like making an effort, even after low physical impact activities.
- A feeling of discouragement and lack of energy even when there is no type of effort.
Anemia is a condition characterized by the reduction of red blood cells in the blood. These are the cells responsible for transporting oxygen through the body.
Often, when the oxygenation process of tissues and the brain becomes difficult, the patient tends to feel tired and weak both physically and mentally.
In addition to tiredness, the patient can show signs such as:
- Paleness of the skin
- High resting heart rate
- Brittle hair and nails
3. Heart failure
Heart failure occurs when the heart loses its ability to pump enough blood to other parts of the body.
Since it hinders circulation, cellular oxygenation is reduced. Therefore, this leads to feeling weak and fatigued.
In the initial stages, the patient may only feel tired when performing moderate activities. However, as time goes on, chronic fatigue will start to take over, even when doing daily tasks such as brushing your teeth.
Fatigue caused by heart failure is often accompanied by:
- Swelling of the limbs (edema),
- Shortness of breath when performing physical activities or while resting,
- Not wanting to make any sort of effort whether it be moderate or small,
- High blood pressure,
- Circulatory difficulties,
- Feeling of heaviness in the legs,
- Pain or stitches in the chest.
Diabetes is caused by the excessive accumulation of glucose in the blood. Whether due to a lack of insulin, or resistance to it, the substance is not used by cells to generate energy.
Without getting enough sugar, body cells “go hungry,” and if they don’t perform their functions correctly, they trigger painful symptoms.
A patient may suspect diabetes when, in addition to constant tiredness, there are other symptoms such as:
- Feeling thirsty,
- Sudden weight loss,
- Changes in urination
- Weakness in the legs.
5. Sleep disturbances
It’s not strange that after a bad night’s sleep, a person feels physical tiredness and finds it difficult to stay concentrated and mentally active.
Getting a good night’s sleep (no less than 7 hours a day without interruptions) is essential in order to renew your body’s energy.
If for several nights you have difficulty sleeping, or if your sleep is interrupted, then you may experience episodes of chronic tiredness.
In this case, you may be able to determine the cause if you also experience:
- Drowsiness during the day,
- Sleep apnea,
- Difficulty falling asleep at night,
- Feeling like sleep didn’t renew your body’s.
Depression is a psychiatric illness and its main symptom is a sudden change in mood. A patient suffering from depression also tends to be sad, with low self-esteem and energy.
This condition is different from the normal sadness that you generally only feel when you’re going through a bad time.
Ignoring depression can turn it into a chronic disease with physical, mental and emotional consequences.
This condition should be considered if, in addition to chronic fatigue, you experience:
- A feeling of discouragement,
- Low self-esteem,
- Deep sadness,
- Stress and anxiety,
- Social seclusion,
- Loss of interest in your daily activities.
Do you constantly feel tired? Do you lack the energy to carry out your daily tasks?
If you are experiencing these symptoms and you are feeling other types of discomfort, consult your doctor to find out if it has anything to do with any of these illnesses.
