Fatigue is a natural thing experienced by anyone due to routine work or sports. But if you suddenly feel more tired than usual while doing your daily routine as usual, chances are you experience activity intolerance. Although extreme fatigue only occurs occasionally or when doing heavy physical activity, this cannot be underestimated. Extreme fatigue can be a sign of more serious health problems.
What is activity intolerance due to extreme fatigue?
Activity intolerance is a condition in which a person cannot carry out a physical activity which is generally considered to be carried out by groups of individuals of the same sex and age.
Activity intolerance is triggered by extreme fatigue due to lack of energy intake due to disruption of food nutrients and oxygen. The level of activity intolerance can vary, meaning that fatigue or decreased activity capacity can arise when a person is doing moderate or heavy work - even when doing light work.
Some chronic diseases can cause activity intolerance
Intolerance of activity can be experienced by someone suffering from heart disease or mitochondrial disorders as energy producers at the cellular level. This total mager syndrome can also be experienced by someone who has metabolic syndrome such as obesity and diabetes. But most of the main causes of activity intolerance are diastolic heart failure.
Diastolic heart failure is a condition when the heart does not get enough blood flow during the relaxation phase of the heart rate. This causes less blood from the heart to be pumped throughout the body and eventually the amount of oxygen and nutrients distributed is insufficient, especially when doing physical activity or exercise.
Simply put, the condition of diastolic heart failure causes the muscles not to get enough blood needed when they are actively doing work, causing activity intolerance. This is characterized by a decrease in performance and capacity both in exercise and daily activities.
Signs and symptoms of extreme fatigue (activity intolerance)
Here are some things that need to be suspected as signs of activity intolerance, including:
1. Too tired fast
Anyone can experience extreme fatigue while doing physical work, including someone who has a fit physical condition, because muscles must have to process oxygen and nutrients simultaneously.
However, in individuals who experience activity intolerance, extreme fatigue can appear within minutes of starting an activity which is characterized by running out of breath and the muscles feel weak. Even worse if it can arise when doing activities that do not use too much muscle, such as when eating or writing.
2. Muscle is easy to cramp
Warming up is one way to avoid muscle cramps and increase heart rate just before exercise. But if you experience intolerance to activities, warming up and light exercise can cause cramps. Even the pain caused can last up to several days.
3. Blood pressure changes
Activity intolerance is usually characterized by changes in normal blood pressure when not doing physical activity but immediately increases dramatically to become high blood pressure when standing or walking goods for several minutes.
4. Heart rate too low
Heart rate that is too low is defined as no significant increase in heart rate when there is an increase in the intensity of physical activity. A healthy heart rate will increase rapidly with the intensity of muscle movements, whereas if the heart rate is too low then it shows that the heart capacity cannot meet metabolic needs due to increased activity intensity.
5. Depressive symptoms
Mental fatigue such as a decrease in concentration can be experienced by someone after exercise, but if someone is experiencing activity intolerance, mental fatigue can trigger depressive symptoms such as irritability, lack of strength, sadness, anxiety and disorientation.
6. Experiencing cyanosis
Cyanosis is a condition of discoloration of the facial skin to become pale due to interference with blood flow or disruption of oxygen distribution while exercising. Cyanosis is a serious condition and requires immediate medical treatment.
Who is at risk of experiencing activity intolerance?
Intolerance of activity can be experienced by anyone who experiences a health disorder that has the potential to disrupt blood circulation. Activity intolerance is more likely to be experienced by adolescents and adults who experience metabolic syndrome problems and heart health disorders.
Activity intolerance can also occur at the age of children. But the root causes tend to originate from disorders of the respiratory, cardiovascular, and nervous system muscles as well as disorders due to mental stress that have an impact on physical and behavioral conditions.
Tips to overcome extreme fatigue (activity intolerance)
Here are some ways to minimize the appearance of activity intolerance, especially if you risk experiencing it:
- Don't stop exercising - maybe you think stopping exercise is the right way to deal with activity intolerance. Actually exercise is still needed to maintain and increase the capacity of blood flow. The exercise session does not need to be too long as long as it can increase the intensity of oxygen intake such as lifting weights several times a week and starting slowly.
- Frequently resting while exercising - this is one strategy to help the body last longer to exercise. Besides exercise with rest periods that often tend to be safe and can be tolerated by someone with a heart problem and a feeling of fatigue is more easily recognized.
- Pay attention to your condition - train yourself to recognize the physical condition when you begin to feel fatigue and stop to rest, at least when your body begins to feel uncomfortable. Avoid overemphasizing and prioritizing health, and review your body's ability to adapt when exercising.
